xattr_remove — Remove an extended attribute

Description

xattr_remove(string $filename, string $name, int $flags = 0): bool

This function removes an extended attribute of a file.

Extended attributes have two different namespaces: user and root. The user namespace is available to all users, while the root namespace is available only to users with root privileges. xattr operates on the user namespace by default, but this can be changed with the flags parameter.

Parameters

filename

The file from which we remove the attribute.

name

The name of the attribute to remove.

flags
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.

Return Values

Returns true on success or false on failure.

Examples

Example #1 Removes all extended attributes of a file

<?php
$file = 'some_file';
$attributes = xattr_list($file);

foreach ($attributes as $attr_name) {
    xattr_remove($file, $attr_name);
}
?>
