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
?>

注释

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