Levenshtein distance function for Doctrine and MySQL
====================================================

[](#levenshtein-distance-function-for-doctrine-and-mysql)

A tiny Doctrine extension for the [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance) algorithm to be used directly in DQL. The `LEVENSHTEIN(s1, s2)` function returns the number of add, replace and delete operations needed to transform one string into another. The `LEVENSHTEIN_RATIO(s1, s2)` function returns the similarity of two strings in percent (`0 createQuery('SELECT u FROM User u WHERE LEVENSHTEIN_RATIO(u.name, :nameQuery) > :minSimilarity');
$query->setParameter('nameQuery', 'michael');
$query->setParameter('minSimilarity', 50)
$matchingUsers = $query->getResult();
```
