xattr_remove -- Remove an extended attribute

## Description

bool xattr_remove ( string path, string name [, int flags])

This function removes an extended attribute named name of a file path.

Extended attributes have two different namespaces: user and root namespace. User namespace is available for all users while root namespace is available only for user with root privileges. xattr operates on user namespace by default, but you can change that using flags argument.

表 1. Supported xattr flags

XATTR_DONTFOLLOW | Do not follow the symbolic link but operate on symbolic link itself.
XATTR_ROOT | Set attribute in root (trusted) namespace. Requires root privileges.

成功した場合に `TRUE` 、失敗した場合に `FALSE` を返します。

例 1. xattr_remove() example

The following code removes all extended attributes of file.

`<?php $file = 'some_file'; $attributes = xattr_list($file); foreach ($attributes as $attr_name) { xattr_remove($file, $attr_name); } ?>`
