Description:
------------
---
From manual page: https://php.net/function.levenshtein
---

The documentation states that arguments 3 to 5 support weights for various actions. These are not implemented (not documented).

The documentation states the weights should be integers. Running with php strict_types reveals it only accepts strings.



Test script:
---------------
<?php
declare(strict_types=1);

$str1 = 'abc';
$str2 = 'abcd';

echo levenshtein($str1, $str2, 0);

//output:
//PHP Fatal error:  Uncaught TypeError: levenshtein() expects parameter 3 to be //string, integer given 

------
<?php
declare(strict_types=1);

$str1 = 'abc';
$str2 = 'abcd';

echo levenshtein($str1, $str2, '0');

//output:
// PHP Warning:  levenshtein(): The general Levenshtein support is not there yet
