Introduction To PHP - World's Best Scripting Language

PHP which is also known as Hypertext Preprocessor is a broadly used, open source general-purpose scripting language that was originally designed for web development to produce dynamic web pages. For this reason, PHP code is implanted into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. PHP code is processed by an interpreter application in command-line mode performing desired operating system operations and producing program output on its standard output channel. The PHP code is enclosed in special start and end processing instructions that allows you to switch into and out of PHP mode. PHP is available as a processor for many of the current web servers and as separate interpreter on most operating systems.

PHP originally stood for personal home page. It was introduce way back in 1994 as a set of Common Gateway Interface (CGI) binaries written in the C programming language.

Simple PHP beginner example

PHP is a general-purpose scripting language that is especially suited to server-side web development where PHP generally runs on a web server. Any PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content. It can also be used for command-line scripting and client-side GUI applications. PHP can be deployed on most web servers, many operating systems and platforms, and can be used with many relational database management systems. It is available free of charge, and the PHP Group provides the complete source code for users to build, customize and extend for their own use.

PHP primarily acts as a filter,taking input from a file or stream containing text and/or PHP instructions and outputs another stream of data; most commonly the output will be HTML. Since PHP 4, the PHP parser compiles input to produce byte code for processing by the Zend Engine, giving improved performance over its interpreter predecessor.

PHP was originally designed to create dynamic web pages, but now PHP focuses mainly on server-side scripting, and it is similar to other server-side scripting languages that provide dynamic content from a web server to a client, such as Microsoft's Active Server Pages, Sun Microsystems' JavaServer Pages, and mod_perl. PHP has also attracted the development of many frameworks that provide building blocks and a design structure to promote rapid application development (RAD). Some of these include CakePHP, Symfony, CodeIgniter, and Zend Framework, offering features similar to other web application frameworks.

The LAMP architecture has become popular in the web industry as a way of deploying web applications. PHP is commonly used as the P in this bundle alongside Linux, Apache and MySQL, although the P may also refer to Python or Perl or some combination of the three.

A new major version has been under development alongside PHP 5 for several years. This version was originally planned to be released as PHP 6 as a result of its significant changes, which included plans for full Unicode support. The new version is set to remove many old features such as the removal of register globals, magic quotes, and safe mode.The reason for the removals was that register_globals had given way to security holes, and magic quotes had an unpredictable nature, and was best avoided. Instead, to escape characters, magic quotes may be substituted with the addslashes() function, or more appropriately an escape mechanism specific to the database vendor itself like mysql_real_escape_string() for MySQL.

How to toggle from an external web server to the built-in web server in Adobe ColdFusion

These are the following easy 6 steps through which you can toggle from an external web server to the built-in web server in Adobe ColdFusion :


For toggling from an external web server to built in web server the first thing you need to do is to take backup of the jrun.xml file.
This file is located under the cf_root\runtime\servers\default\SERVER-INF folder in Windows operating system, and in the cf_root/runtime/servers/default/SERVER-INF directory in UNIX operating system.

1. Now in the next  step you have to open the original jrun.xml file for editing.

2. Now search for the WebService service and set the deactivated attribute to false:

3. Search for the ProxyService service and set the deactivated attribute to true. It can be done like this:





4. Now  save the file.

5. In the next step, you have to copy the CFM pages in your web root directory (including the CFIDE and cfdocs directories) to the ColdFusion cf_root/wwwroot directory, and use appropriate URL references. If you toggle from the built-in web server to an external web server, you must copy the contents of the cf_root/wwwroot directory to your web server root.

Note: In case if you are using Adobe Dreamweaver, you must make sure that you must reconfigure all sites that you move from one server to another.

6. Lastly, restart ColdFusion to see the desired results.

What is Cold Fusion ?

ColdFusion is a commercial rapid application development platform invented by Jeremy and JJ Allaire in 1995. It is mainly developed to make it easier to connect simple HTML pages to a database, but wityh the its version 2 it had become a full platform that included an Integrated Development Enterprise (IDE) in addition to a full scripting language. Current versions of ColdFusion include advanced features for enterprise integration and development of rich internet applications. ColdFusion primarily competes with latest web technologies like PHP and ASP.

Adobe ColdFusion 9 software makes it easy for developers to rapidly build enterprise-ready Internet applications by collaborating complex business logic into fewer lines of code. Plus, unique integration between ColdFusion and the Adobe Flash Platform provides the easiest solution for building rich Internet applications (RIAs) from client to server.

One of the significant features of ColdFusion is its associated scripting language, ColdFusion Markup Language (CFML), which compares to the scripting components of ASP, JSP, and PHP in purpose and features, but more closely resembles HTML in syntax. “ColdFusion” is often used synonymously with “CFML”, but there are additional CFML application servers besides ColdFusion, and ColdFusion supports programming languages other than CFML, such as server-side Actionscript and embedded scripts that can be written in a JavaScript-like language known as CFScript.

ColdFusion is most often used for data-driven web sites or intranets, but can also be used to generate remote services such as SOAP web services or Flash remoting. It is especially well-suited as the server-side technology to the client-side Flex.

ColdFusion can also handle asynchronous events such as SMS and instant messaging via its gateway interface, available in ColdFusion MX 7 Enterprise Edition.

Latest Features in ColdFusion 9

Adobe AIR local/remote database synchronization

This features provides  users applications with online/offline capability featuring reliable data management. Using SQLLite in the client and ORM on the server, ColdFusion 9 manages conflict resolution and data synchronization between the client and server when your application comes back online.

New Ajax controls

Now you can develop more compelling and insightful applications with a wider rangeof Ajax controls that leverage the new Ext JS 3.0 library via CFML tags and attributes. New controls include mapping, multimedia player, multifile upload, accordion navigation, progress indicator, confirmations, alerts, buttons, and sliders etc.

Microsoft Office SharePoint integration

It exposes data from Microsoft Office SharePoint web services to a ColdFusion application with the new CFSHAREPOINT tag. Additionally, use the single sign-on capability in SharePoint to display a ColdFusion application as a web part within a SharePoint site without requiring users to reenter their login information.

Object-relational mapping

With the introduction of this feature you can build database-independent applications using object-relational mapping (ORM) based on the open source Hibernate library. It will surely save the time and manage database logic and connectivity without writing any SQL. You can use the ORM Application Wizard in ColdFusion Builder to generate ColdFusion components (CFCs) for logic and connectivity without writing a single line of code.

Server Manager

It saves time by simultaneously performing administrative tasks across multiple servers from one central console. You can create data sources, schedule tasks, apply hot fixes, clear caches, and compare settings across a cluster of ColdFusion servers.

Office file interoperability

Now by using this feature it is very easy to generate office documents for reporting, decision making, and presentations. Read, create, and update spreadsheets using the new CFSPREADSHEET tag. One can also programmatically generate PDF files from Microsoft PowerPoint and Word files and dynamically produce presentations in HTML or SWF from PowerPoint presentations directly on the server.
