Basically php is combination of two languages that’s C and Perl that’s reason behind its syntax look like C programming language. Today we see several number of versions like php 1.0, php 2.0, php 3.0 and

today we have latest version of php that’s php 7.0.

We can easily embedded the php code into html code, and it can combine in various web templates easily. Php codes are easily interoperated by web-servers without any king of troubles and get the output very fast.

At the beginning time php works under the ZEND Engine and executing the php code using Zend interpreter.

Actually php is open source product and users can easily download from the internet. And it is compatible with MySQL server that is also an open source product.
