(PHP 4, PHP 5)
posix_setgid — Set the GID of the current process
Description
bool posix_setgid
( int $gid
)
Set the real group ID of the current process. This is a privileged function and needs appropriate privileges (usually root) on the system to be able to perform this function. The appropriate order of function calls is posix_setgid() first, posix_setuid() last.
Note: If the caller is a super user, this will also set the effective group id.
Parameters
- gid
-
The group id.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
Example #1 posix_setgid() example
This example will print out the effective group id, once it is changed.
<?php
echo 'My real group id is '.posix_getgid(); //20
posix_setgid(40);
echo 'My real group id is '.posix_getgid(); //40
echo 'My effective group id is '.posix_getegid(); //40
?>
