lchgrp

(PHP 5 >= 5.1.2, PHP 7)

Changes group ownership of symlink

bool lchgrp ( string $filename, mixed $group )

Attempts to change the group of the symlink filename to group.

Only the superuser may change the group of a symlink arbitrarily; other users may change the group of a symlink to any group of which that user is a member.

Parameters:

filename

Path to the symlink.

group

The group specified by name or number.

Returns:

Returns TRUE on success or FALSE on failure.

Notes:

This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script that is being executed.

This function is not implemented on Windows platforms.

Examples:

Changing the group of a symbolic link

<?php
$target = 'output.php';
$link = 'output.html';
symlink($target, $link);

lchgrp($link, 8);
?>
