The group id.

Return Values

Examples

Example #1 posix_setgid() example

This example will print out the effective group id, once it is changed.

<?php
echo 'My real group id is '.posix_getgid(); //20
posix_setgid(40);
echo 
'My real group id is '.posix_getgid(); //40
echo 'My effective group id is '.posix_getegid(); //40
?>
