Script language for dynamic web-pages. The syntax and concepts used are similar to Perl

Loop over an associative array (hash):

 
foreach ( $_POST as $key => $value ) {
            echo $key.' '.$value.' '.$_POST[$key].'<br>';
        }

Functions

Function have global scope, you do not need to declare them before calling

<?php
function func1($arg1, $arg2)
{
    <codeblock>
    return $value;
}
?>

On debian (and its derivates)

apt-get install php-fpm php-mysql: Install php7 and mysql support; Fix php security by editing /etc/php/7.0/fpm/php.ini; Uncomment line with cgi.fix_pathinfo and set it to 0
