Return Values

Examples

Example #1 posix_getegid example

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

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

Notes

posix_getegid is different than posix_getgid because effective group ID can be changed by a calling process using posix_setegid.
