How to Set Global Environment Variables for PHP

How to make global variables in php

Your question is kinda ambiguous for me. If you mean setting a variable from one file then making it available from all your php files you can put it in one file then include the file it in all your scripts. Put it on the top. Or you can put it inside an $_SESSION variable. This is the simplest solution I know. :)

Sample: Assuming all files are in the root directory

vars.php:

$globalVar = 2;
//or 
$_SESSION['global_var'] = 2; // if a session exists

otherfile.php:

include 'vars.php';
echo $globalVar; //outputs 2
//or
echo $_SESSION['global_var']; //outputs 2

I'm not sure if this is what you are trying to achieve :D
