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

Return the numeric effective group ID of the current process.

Return Values

Returns an integer of the effective group ID.


Example 1868. posix_getegid() example

This example will print out the effective group id, once it is changed with posix_setegid().

echo 'My real group id is '.posix_getgid(); //20
'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().
