posix_getegid
(PHP 4, PHP 5, PHP 7, PHP 8)
posix_getegid — Return the effective group ID of the current process
Description
posix_getegid(): int
Return the numeric effective group ID of the current process.
Parameters
This function has no parameters.
Return Values
Returns an int of the effective group ID.
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().
