Example


<?php

include(dirname(__FILE__) . '/../../src/php/Fuzzion.php');



function test()

{

    $matcher = new Fuzzion();

    $tests = [

    ['jointure', 'join'],

    ['jointure', 'jiontre'],

    ['jointure', 'joitnrue'],

    ['jointure', 'turejoin'],

    ];



    foreach ($tests as $test)

    {

        $string1 = $test[0];

        $string2 = $test[1];

        echo "\n"; echo('levenshtein("'.$string1.'", "'.$string2.'") = '.strval($matcher->levenshtein($string1, $string2)));

        echo "\n"; echo('damerau("'.$string1.'", "'.$string2.'") = '.strval($matcher->damerau($string1, $string2)));

        echo "\n"; echo('lcs("'.$string1.'", "'.$string2.'") = '.strval($matcher->lcs($string1, $string2)));

        echo "\n"; echo('jaccard("'.$string1.'", "'.$string2.'") = '.strval($matcher->jaccard($string1, $string2)));

        echo "\n"; echo('overlap("'.$string1.'", "'.$string2.'") = '.strval($matcher->overlap($string1, $string2)));

        echo "\n"; echo('hamming("'.$string1.'", "'.$string2.'") = '.strval($matcher->hamming($string1, $string2)));

        echo "\n"; echo('jaro("'.$string1.'", "'.$string2.'") = '.strval($matcher->jaro($string1, $string2)));

        echo "\n"; echo('ngram("'.$string1.'", "'.$string2.'", 2) = '.strval($matcher->ngram($string1, $string2, 2)));

        echo "\n"; echo('ngram("'.$string1.'", "'.$string2.'", 3) = '.strval($matcher->ngram($string1, $string2, 3)));

        echo "\n";
