FuzzyWuzzy

Fuzzy string matching for PHP, based on the python library of the same name.

Requirements

• PHP 5.4 or higher

Installation

Using Composer

composer require wyndow/fuzzywuzzy

Usage

use FuzzyWuzzy\Fuzz;
use FuzzyWuzzy\Process;

$fuzz = new Fuzz();
$process = new Process($fuzz); // $fuzz is optional here, and can be omitted.

Simple Ratio

>>> $fuzz->ratio('this is a test', 'this is a test!')
=> 96

Partial Ratio

>>> $fuzz->partialRatio('this is a test', 'this is a test!')
=> 100

Token Sort Ratio

>>> $fuzz->ratio('fuzzy wuzzy was a bear', 'wuzzy fuzzy was a bear')
=> 90
>>> $fuzz->tokenSortRatio('fuzzy wuzzy was a bear', 'wuzzy fuzzy was a bear')
=> 100

Token Set Ratio

>>> $fuzz->tokenSortRatio('fuzzy was a bear', 'fuzzy fuzzy was a bear')
=> 84
>>> $fuzz->tokenSetRatio('fuzzy was a bear', 'fuzzy fuzzy was a bear')
=> 100

Process

>>> $choices = ['Atlanta Falcons', 'New York Jets', 'New York Giants', 'Dallas Cowboys']
>>> $c = $process->extract('new york jets', $choices, null, null, 2)
=> FuzzyWuzzy\Collection {#205}
>>> $c->toArray()
=> [
     [
       "New York Jets",
       100,
     ],
     [
       "New York Giants",
       78,
     ],
   ]
>>> $process->extractOne('cowboys', $choices)
=> [
     "Dallas Cowboys",
     90,
   ]

You can also pass additional parameters to extractOne to make it use a specific scorer.

>>> $process->extractOne('cowbell', $choices, null, [$fuzz, 'ratio'])
=> [
     "Dallas Cowboys",
     38,
   ]
>>> $process->extractOne('cowbell', $choices, null, [$fuzz, 'tokenSetRatio'])
=> [
     "Dallas Cowboys",
     57,
   ]

Caveats

Unicode strings may produce unexpected results. We intend to correct this in future versions.
