xattr_remove Remove an extended attribute


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

Supported xattr flags

Return Values

Example #1 Removes all extended attributes of a file

= 'some_file';
$attributes = xattr_list($file);

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