PHP – How to find the origin of the call on a PHP function

It can happen that a function is only callable from one interface (console, apache…). There is a function that returns exactly what we are looking for.

In the following example, we are looking to know whether the call is from the console.

if (php_sapi_name() != "cli") {
    header("Location: http://www.sadtrombone.com/");
    die();
}
