I’m just going to leave this nifty little PHP snippet here, and recommend against it’s use. It could very well be shorter and more concise, probably a bit more performant too, but it works:

| class Example { | |
| public function length(){ | |
| return 5; | |
| } | |
| public function __call($name,$arguments){ | |
| $methods = get_class_methods($this); | |
| $ldist = 9999; | |
| $currmethod = $name; | |
| foreach($methods as $m){ | |
| $distance = levenshtein($name,$m); | |
| if($distance < $ldist){ | |
| $currmethod = $m; | |
| $ldist = $distance; | |
| } | |
| } | |
| return call_user_func(array($this,$currmethod),$arguments); | |
| } | |
| } | |
| $example = new Example(); | |
| echo $example->elngth(); |
It also encourages bad practices and ambiguity ( should elngth be mapped on to length1 or length2? If you’re willing to run levenshtein in your head, maybe you should spell correctly ).
Inspired by this tweet:
>>> def method_missing(n, *a, &b); send(methods.min_by { |m| levenshtein(n.to_s, m.to_s) }, *a, &b); end
>> p [1, 2, 3].elngth
3It's fine.
