# lchgrp

(PHP 5 >= 5.1.2, PHP 7)

lchgrp — Changes group ownership of symlink

### Description

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.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example #1 Changing the group of a symbolic link

`<?php
$target = 'output.php';
$link = 'output.html';
symlink($target, $link);
lchgrp($link, 8);
?>`

### Notes

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

> Note: 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.

> Note: This function is not implemented on Windows platforms.
