posix_getegid — Return the effective group ID of the current process
Return the numeric effective group ID of the current process.
Returns an integer of the effective group ID.
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
?>
posix_getegid() is different than posix_getgid() because effective group ID can be changed by a calling process using posix_setegid() .
