Description

string getenv (string varname)

Returns the value of the environment variable varname, or FALSE on an error.


<?php
// Example use of getenv()

// Or simply use a Superglobal ($_SERVER or $_ENV)

You can see a list of all the environmental variables by using phpinfo(). You can find out what many of them mean by taking a look at the CGI specification, specifically the page on environmental variables.
