posix_getegid -- Return the effective group ID of the current process

Description

int posix_getegid ( void )

Return the numeric effective group ID of the current process.

Return Values

Returns an integer 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().
