<?php
$df = get_defined_functions(true);

var_dump(in_array('sha1', $df['internal'], true));
var_dump(is_string(sha1('foo')));

var_dump(in_array('hash', $df['internal'], true));
var_dump(is_string(hash('md5', 'foo')));
?>
$ php -d disable_functions=sha1_file,password_hash disable.php


Expected result:
----------------
bool(true)
bool(true)
bool(true)
bool(true)


Actual result:
--------------
bool(false)
bool(true)
bool(false)
bool(true)
