CakePHP is easily the best form of PHP for developing websites. It is not only highly flexible, but it is also a reliable and tested tool for programmers. So what is it that makes CakePHP development so suitable for development?

CakePHP framework is totally compatible with PHP 4 and PHP 5 and can be integrated with CRUD too.Since its launch in 2005, CakePHP development has gained wide acceptance and has left its mark in the field of open source frameworks for web development.
CakePHP development comes with all the advantages of PHP minus its haphazard nature! It strikes a perfect balance of flexibility and structure which its counterparts like Prado, CodeIgniter, Agavi and the likes fail to provide.
Its noteworthy features include:
  • Code generation via Bake
  • Access control lists
  • Application scaffolding request dispatcher with custom URLs
  • Data sanitation
  • Integrated CRUD for database security
  • Session and Request handling components
  • Robust User Community - Active Development of the Core Code
  • Simplified querying
  • Website directory independent
  • In-built validation

CakePHP is easy to license, flexible, generates codes automatically (using Bake), resolves data management issues using CRUD framework and most importantly, offers tones of support from the CakePHP development community.
Coming back to the main question – Why should you choose CakePHP for web application development? For one, CakePHP framework is easy to use and speeds up development. It also enables programmers to write their code in the MVC environment, thus, presentation and logic are not mixed. Using PHP, programmers can easily manage tables and classes. It also has an articulate directory structure and offers faster development time.
Working with CakePHP web development framework PHP developers do not need to set up configuration since LAMP configuration is automatically modified in accordance with developers' changes. It supports Ajax, JavaScript, XML and other languages and technologies; ensures robust security and authorization for future web applications.
This is just a brief outline of the CakePHP framework. To know it better and understand its features in more detail… you need to experience developing at the hands of CakePHP!
CakePHP Development is very much suitable if you want to give a boost to your web development process.
See it, to believe it!

Cloud computing technologies involve a definite style of computing which consist of dynamically scalable resources which help in delivering solutions and service over the Internet. Users need not be aware of the technology infrastructure but need to understand that the cloud houses all the resources that you need a monthly cost.
• Infrastructure as a service (IaaS)Multiple combinations for cloud computing work succinctly in any type of organization:
• Platform as a service (PaaS)
• Software as a service (SaaS)
Cloud computing services often deliver applications through the web browser while data is stored in the servers. Computer hardware is primarily used for all processes of the software development lifecycle and devoted to fulfill non-business critical requirements. Sometimes companies outsource part of the SDLC to different companies due to shortage of inhouse resources. Many risks are associated with such scenarios. The vendor's infrastructure is rarely transparent and hence it is found that mostly they are unaware of all the billing that is taking place in terms of effort put in the tasks. Huge investment is made firsthand but that does not guarantee the future work involved.
The client does not have any clue as to the working of the client's infrastructure which might result in confusion. Inefficient development methodology can also ruin the development processes since resources are wasted and have to be paid any way.

Major problems are caused due to continuous hardware scaling & the new systems seldom portray performance issues too. Many such factors are crucial for the success of the companies and hence they opt to reduce outsourcing of tasks related to the IT world.
Cloud architecture which is dedicated to the delivery of cloud computing services includes hardware and software designed by cloud architects who forms an alliance with a cloud integrator. A number of cloud components play an important role in communicating with each other of APIs especially the use of web services.
With cloud computing, organizations can lessen the IT complexity and strategic plans can be opted for, to manage resulting systems which are much more effective that the earlier systems. The cloud architecture is extensible to the client too, where web browsers and/or software applications access cloud applications.
Here are some of the salient characteristics of Cloud Computing
  • Rapid and inexpensive method for computing since it is not intensive on resources
  • Cost effective means since most of the capital expenditure is just transformed into operational expenditure
  • Location independence is boosted considerably and users can start using the web browser
  • Multi-tenancy options with equitable sharing of resources and applicable for a large number of users in an organization
  • Immense Reliability and scalability for rapid business continuity
  • Safety and Security options due to centralized data and focused resources

This degradable form validation demo verifies the form at the server side on the classic form submit, and also implements AJAX validation while the user navigates through the form.

Degradable AJAX Form Validation

Doing a final server-side validation when the form is submitted is always a must. If someone disables JavaScript in the browser settings, AJAX validation on the client side won't work, exposing sensitive data, and thereby allowing an evil-intended visitor to harm important data back on the server (for example, through SQL injection). Always validate user input on the server!

This form validation application validates a registration form, using both AJAX validation (client side) and typical server-side validation:

* AJAX-style (on the client), when each form field loses focus (onblur). The field's value is sent to the server, which validates the data and returns a result (0 for failure, 1 for success). If validation fails, an error message will unobtrusively show up and notify the user about the failed validation.
* PHP-style (on the server), when the entire form is submitted. This is the usual validation you would do on the server, by checking user input against certain rules. If no errors are found and the input data is valid, the browser is redirected to a success page. If validation fails, however, the user is sent back to the form page with the invalid fields highlighted.

Both AJAX validation and PHP validation check the entered data against these rules:

* Username must not already exist in the database
* Name field cannot be empty
* A gender must be selected
* Email address must be written in a valid email format, such as xyz@domain.com
* Phone number must be written in standard US form: +xx xxxxxxxxx

Thread-Safe AJAX

A piece of code is thread-safe if it functions correctly during simultaneous execution by multiple threads. In this exercise, we need to make an asynchronous request to the server to validate the entered data every time the user leaves an input box or changes a selection.

The hidden danger behind this technique is only revealed if the user moves very quickly through the input fields, or the server connection is slow; in these cases, the web application would attempt to make new server requests through an XMLHttpRequest object that is still busy waiting for the response to a previous request (this would generate an error and the application would stop functioning properly). 


Depending on the circumstances at hand, the ideal solution to this problem may be:

* Create a new XMLHttpRequest instance for every message you need to send to the server. This method is easy to implement, but it can degrade server's performance if multiple requests are sent at the same time, and it doesn't guarantee for the order in which you receive the responses.
* Record the message in a queue and send it later when the XMLHttpRequest object is able to make new requests. The requests are made in the expected order. Using a queue is particularly important in applications where the order of the messages is important.
* Schedule to automatically retry making the request after a specified amount of time. This method is similar to the one with the queue in that you don't make more than one server request at a time, but it doesn't guarantee for either the order in which the requests are made, or for the order in which the responses are received.
* Ignore the message.

In this form validation exercise, we use a message queue. When the user leaves an input element, a message to validate its value is added to the queue. When the XMLHttpRequest object is clear to make a new request, it takes the first message from the queue.

The queue is a First-In, First-Out (FIFO) structure, which guarantees that the messages are sent in the proper order. To get a feeling about how this works, go to the demo page, and press tab quickly multiple times, and then wait to see how the validation responses show up one by one.

PHP which is officially known as ‘Hypertext Preprocessor' was released in the year 1995. Initially written as a set of Common Gateway Interface (CGI) in ‘C', PHP was originally designed to replace a set of Perl scripts to maintain his Personal Home Pages (also known as PHP). PHP was originally designed to create dynamic and more interactive web pages. It is the most widely-used, open-source and general-purpose scripting language. It is a server-side scripting language often written in a HTML context. PHP code in a script can query databases, create images, read and write files and talk to remote servers. The output from PHP code is combined with HTML in script and the result is sent to the user.
It is possible to use PHP in almost every operating system. PHP can be used in all major operating systems including Linux, Microsoft Windows, Mac OS X, and RISC OS. PHP uses procedural programming or object oriented programming and also a mixture of them. PHP is used mainly in server-side scripting, command line interface and writing desktop applications. PHP also supports ODBC, the Open Database Connection standard which allows you to connect to other databases supporting this world standard. Server-side scripting is the most traditional one for PHP development. In order to use PHP for server-side scripting you need a PHP parser, a web server and a web browser. The PHP codes entered with the parser on a web server will be translated into a PHP page that can be viewed on your web browser. 

PHP is a popular language because it can be embedded directly into HTML coding. It has more benefits such as the following - it can be used on all major operating systems and can be supported by most of the web servers. The latest version of PHP development is a very stable and grown-up language used for web programming like Java and Microsoft C#. Both the PHP engine and the PHP code can be used on any platform, which makes PHP extremely flexible.

PHP has many features designed specifically for use in websites. PHP can be used to make your website secure by implementing mandatory sign in feature – asking the user or the administrator to enter a valid username and password. Adding such a feature is easy as PHP can display a HTML form and process the information that the user types in. This ‘sign in' feature can be an excellent way of getting to know about your customer's profile. 

The popularity of PHP Development continues to grow rapidly because it has many advantages. PHP is fast because the time needed to process and load a webpage is relatively low. PHP is also versatile and it runs on a wide variety of operating systems. PHP hosting is a server-side scripting environment that is used to create dynamic web pages. It is an open source language which is widely used by programmers and web developers. Open source gives a lot of advantages over proprietary programming languages. Due to this reason, PHP has been the one of the most popular server-side scripting language so far. Almost all the hosting providers offer PHP hosting services these days. PHP is especially strong in relational databases, which are used for dynamic content and e-commerce applications.

Software application development began with desktop applications, which could be used on standalone machines only. However, with the advent of internet and online commerce, web application development gained importance. Word processors and media players can be considered to be typical desktop applications, while an online shopping cart on an ecommerce website can be considered as a web application.
By definition, a desktop application means any software that can be installed on a single computer (laptop or a desktop) and used to perform specific tasks. Some desktop applications can also be used by multiple users in a networked environment. Web application development, however, soon started replacing desktop applications for reasons of portability and better functions from usability point of view. Web application development is usually made on client-server architecture and use a web-browser as the client interface. This is one of the reasons why web applications are so widely getting popular. Though web applications offer a slight advantage over desktop applications, there is a very narrow chance of desktop applications becoming outdated. The primary reason for this could be the security issues and legalities associated with web based applications.
Following is a basic comparison on desktop and web based applications based on certain parameters:

  • Maintenance - web based applications need to be installed only once where as desktop applications are to be installed separately on each computer. Also updating the applications is cumbersome with desktop applications as it needs to be done on every single computer which is not the case with web applications.
  • Ease of use - desktop applications are confined to a physical location and hence have usability constraint. Web applications development on the other hand makes it convenient for the users to access the application from any location using the Internet.
  • Security - web applications are exposed to more security risks than desktop applications. You can have a total control over the standalone applications and protect it from various vulnerabilities. This may not be the case with web applications as they are open to a large number of users in the Internet community thus widening the threat.

  • Connectivity - web application development relies significantly on Internet connectivity and speed. Absenceof Internet or its poor connectivity can cause performance issues with web applications. Desktop applications are standalone in nature and hence do not face any hindrances resulting from Internet connectivity. Connectivity also significantly affects the speed at which desktop and web applications operate.

  • Cost factor - web application development and its maintenance involve higher costs and mostly recurring in nature. Desktop applications are purchased one time and there are not continually occurring charges. However, in certain cases, maintenance fees may be charged.

Having considered the basics of desktop and web application development, the selection of a suitable type will depend on the business needs and factors discussed in the comparison given above.

Through concept such as Ajax and scripting languages like PHP, we now have a much robust set tools with which to deal with imaging. Thorugh Ajax, we can dynamically load and display images without the rest of the page having to reload, which speeds up the process considerably. We also have more control over what the user sees while the screen or images load. Users are generally understanding of load times, provided that you let them know what is happening. Thorugh Ajax and a little PHP magic, we can help the user's experience be a seamless and enjoyable as possible.

The basic uploading, manipulating and dynamically displaing images using PHP and Ajax.

Uploading Images
I suppose it is neccessary to bring a little bad news to Ajax at this point, it is not possible to process a file upload through the XMLHtrtpRequest Object. The reason of this is that javascript has no access to your computer's file system. While this is somewhat disappointing, there are still ways to perform Ajax-like functionality for this wighout making use of the XMLHttpRequest Object. Clever developeres have discovered that you can use hidden iframes to post a form request, thereby allowing for a image upload wiothout refresh.

I am designing a website with ajax and php. My main target is doing everything without full page refresh. I have done everything completed. I solved it partially using IFRAME.

By setting the iframe's CSS display property to none, the element is persent on the page to be utilized by the upload form, but not visible to the end user. by assiging a name to the iframe tag, you can use the target attribute in the form tag to post the request to the hidden iframe. Once you have the iframe configured, you can perform any uploads you like, and then use Ajax to perform any extra functionality. Consider the following example, which will allow yout to upload an image to a folder of your specification. Consider the code, which will allow you to create application.

An Ajax-enabled file upload system that uses hidden iframes to hide the upload
The code to create form, with a hidden iframe for processing

As you can see, you are using the same functionality and you will now use it to load the recently uploaded image into your 

web page dynamically and without a screen refresh. The uploading function will still perform your form submission, but it is now coupled with a function called downloading, which will fire once the process_upload.php script has finished uploading the image (determined by the onload evernt). The doneuploading function takes ther parent frame of the hidden iframe and the fine name as arguments. It then users Ajax to dyanmically load the image the speicified element of ther parent frame.

Im trying to create a page for a picture framing site where users can upload images to see how they would look framed.

Uploading images can be broken down into the three following steps which will be looked at in turn:

* An HTML form with a browse button to allow the client to choose which file to upload
* A script to process the upload, validate the file, name it and place it in the file system
* Lastly a page to advise the client the upload was a success
* Is there a AJAX based solution or PHP based solution to check the filesize a user is trying to upload via a form.
* If the filesize exceeds more than 2 MB we want to give a message to the user that they need to upload a smaller file 

size.

You can upload ZIP file of all your images in one shoot. You can upload image using zip file.
* You can create zip file for image, doc file and other file.
* This script find only jpg file uploaded and other file deleted.
* You can set which extension allowed or not allowed using this script uploaded.
