PHP Language: The Hypertext Processor

PHP is one of the most commonly used wide purpose languages for scripting purposes. It was originally produced to develop websites and create dynamic website pages. For this reason, you will often find PHP code embedded into an HTML document, which acts as the source. This is interpreted through the use of a PHP processor (module) by a web server. As a result, a webpage document is produced.

PHP code, being a programming language used for general purposes, is processed through an application used for interpretation. It is used in a line of command mode, and it performs the required operations from the operating system. The output produced by the program is on the standard channel used for output. In fact, this can also act as a graphic program. The majority of recent web servers will offer PHP for processing purposes. It is also available as an interpreter that is a standalone with most computing platforms and operating systems.

PHP actually stands for “personal home page.” When its development started in 1994, Rasmus Lendorf, a programmer from Greenland, invented a Perl script set which he called “Personal Home Page Tools.” This was due to the fact that it maintained his personal homepage as well as performed tasks such as displaying a resume and noting the level of traffic being attracted by his webpage.

Originally invented by Rasmus Lendorf in the year 1995, PHP has continuously been improved since then. The core implementation of PHP is currently being produced by PHP Group. It serves to be the standard of de facto as far as PHP is concerned. In spite of no formal specifications existing, PHP is offered as free software. It is released under the hood of the PHP License.

PHP is a very useful invention that the modern computing would find it hard to manage without. Learn more about it to optimize its use in your computing applications.

Why PHP is a Popular Choice for the Web

PHP (Hypertext Pre-Processor) is a scripting language that’s behind the success of a number of popular websites. If you are a programmer or a tech-savvy user who works with programs like Putty and Tight VNC, you must have heard about several other programming languages meant for the Web development, such as Java, ASP, ASP.NET, CGI-Perl etc. However, the fact that the number of websites built using PHP is much higher than those written using its counterparts indicates the degree of popularity PHP has. Let us understand what makes PHP such a popular choice for Web development:
1. PHP is available as free and open-source software like the popular FileZilla FTP software. This reduces a development and maintenance cost to a great extent.
2. PHP is compatible with a number of application servers and Web servers. Thanks to its present degree of popularity, almost all the upcoming and new Web servers are being developed with a default native support for running PHP-based Web applications.
3.  The current version of PHP supports OOP (Object Oriented Programming) as well as its traditional scripting way of writing applications. This has also drawn interest of the developers who often prefer OOP-based programming over procedural programming or scripting.
4. PHP, being an open-source software like NotePad, has a support of a huge community of developers from all over the world. As a result, it has become much easier for everyone to find solutions to complex programming situations and problems faced while developing for the Web.
5. Speed of writing code in PHP is often quite less than its competitor language, Java. This is because it does not require programmer to think of information in form of objects even for the simplest of tasks. This is why less amount of boilerplate code is required for wiring various parts of the program.

Of course, it’s wise to choose a programming language based on the set of requirements. However, PHP is a potential candidate when you’re trying to decide the best language to develop a Web application.
