get_current_user
Name
get_current_user — Determines the owner of a PHP
script.
Synopsis
string get_current_user(void)
Returns
Owner of script file
Description
Returns the owner of the file containing the script, not
the username of the process executing the script. For
instance, while one user may own the script, the name of
the user executing the script may be the web server.
Depending on the platform that PHP is running on, this
can have an effect if attempting to perform such tasks as
file system access.
get_current_user() can also be used to provide a
small measure of system security. By comparing the owner
of the script to the owner of a file, Trojan horse type
exploits can be partially minimized. This is useful only
on systems with a concept of multiple users and
permissions, such as UNIX-based systems.
Example
Example 995. Display owner of
the current script
<?php
echo get_current_user();
?>
