posix_getegid
Return the effective group ID of the current process
(PHP 4, PHP 5)
int posix_getegid ( )
Examples
Example 1868. 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().
