Web Development Using PHP
Introduction:
PHP source code php is a symbol of Hypertext Preprocessor, previously known as Personal Internet site, is a widely used, general-purpose scripting language who was originally designed for web site development, to produce active web pages. It is a excellent language for the immediate development of active Websites. Here some term has been implemented, the "Scripting Language", is a programming words that allows control of 1 or more software applications. "Scripts" are distinct from the core code of the application. It can be inserted into HTML(Hyper Text message Markup Language) along with generally runs using a web server, It usually is deployed on most web site servers and with almost every operating systems or platforms free of charge.

Unencumbered with licensing restrictions imposed by most industrial products.
Basically PHP is Open Base Software.
Everyone is free to participate.
Originally it happens to be designed to create dynamic web pages.
PHP at this moment focuses mainly with server-side scripting.
PHP is a loosely-typed dialect, which also boosts its practicality. For instance , there is no need to explicitly create, typecast, or simply destroy a changing, although you are not stopped from doing so.
Make and manipulate Macromedia Flash, image, and additionally Portable Document File (PDF) files
Measure a password designed for guess ability just by comparing it so that you can language dictionaries, and easily broken designs

In order to speed up delivery time and not have to make the PHP source code every-time your web-page is looked at, PHP scripts is usually stored in binary format using PHP compilers.
Code optimizers aim to reduce the run-time of the compiled passcode by reducing a size and producing other changes that could reduce the execution period with the goal with improving performance.
One other approach for trimming overhead for high load PHP staff is using an Opcode cache.
PHP is way faster after that any other server scripting language.
