PHP is one of the most important web programming languages to learn, and knowing it, will give you SUPER POWERS in the web development world and job market place.Because Millions of websites and applications (the majority) use PHP. You can find a job anywhere or even work on your own, online and in places like freelancer or Odesk. You can definitely make a substantial income once you learn it.
PHP is a SERVER-SIDE language designed for WEB-DEVELOPMENT but also used as a GENERAL PURPOSE PROGRAMMING LANGUAGE. Originally created by RASMUS LERDOF in 1994, the PHP reference implementation is now produced by The PHP Group. PHP originally stood for Personal Home Page, but it now stands for the RECURSIVE ACRONYM.Â
PHP code may be embedded into HTML code, or it can be used in combination with various WEB TEMPLATE SYSTEMS, web content management systems, and WEB FRAMEWORKS. PHP code is usually processed by a PHP interpreter implemented as a module in the web server or as a COMMON GATEWAY INTERFACE (CGI) executable. The web server combines the results of the interpreted and executed PHP code, which may be any type of data, including images, with the generated web page. PHP code may also be executed with a COMMAND LINE INTERFACE(CLI) and can be used to implement standalone graphical applications.
The standard PHP interpreter, powered by the zend engine, is free software released under the PHP LICENSE. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge.
The PHP language evolved without a written FORMAL SPECIFICATION or standard until 2014, leaving the canonical PHP interpreter as a
PHP is a server-side scripting language designed for web development but also used as a general-purpose programming language. Originally created by Rasmus Lerdorf in 1994,[1]the PHP reference implementation is now produced by The PHP Group.[2] PHP originally stood for Personal Home Page, but it now stands for the recursive backronym PHP: Hypertext Preprocessor.

The PHP language evolved without a written formal specification or standard until 2014, leaving the canonical PHP interpreter as a de facto standard. Since 2014 work has gone on to create a formal PHP specification.[7]
During the 2010s there have been increased efforts towards standardisation and code sharing in PHP applications by projects such as PHP-FIG in the form of PSR-initiatives as well as Composer dependency manager and the Packagist repository. PHP hosts a diverse array of web frameworks requiring framework-specific knowledge, with Laravel recently emerging as a popular option by incorporating ideas made popular from other competing non-PHP web frameworks, like Ruby on Rails

PHP Advantages.
Knowing PHP will allow you to build web applications, websites or Content Management systems, like WordPress, Facebook, Twitter or even Google.The following functions can be performed by using PHP language.
- Object Oriented PHP
- CMS project-similar to (WordPress)
- Form Submissions in PHP
- Security in PHP
- Variables in PHP
- Math in PHP
- Arrays in PHP
- Control Structures in PHP
- Comparison Operators in PHP
- Mayor Loops in PHP
- Functions in PHP
- Constants in PHP
- Super Globals in PHP
- Sessions in PHP
- Cookies in PHP
And much more ….
PHP also has powerful output buffering that further increases over the output flow. PHP internally rearranges the buffer so that headers come before contents.
PHP is dynamic. PHP works in combination of HTML to display dynamic elements on the page. PHP only parses code within its delimiters, such as. Anything outside its delimiters is sent directly to the output and not parsed by PHP.
PHP can be used with a large number of relational database management systems, runs on all of the most popular web servers and is available for many different operating systems.
PHP5 a fully object oriented language and its platform independence and speed on Linux server helps to build large and complex web applications.
So, in general PHP is cheap, secure, fast and reliable for developing web applications.
