Hi, I'm trying to obtain the similarity percentage for 2 Strings when using the Levenshtein function but the percentages doesn't seem to match the percentage returned by similar_text($str1,$str2,$match_percent);
Below is what I use to calculate the similarity percentage
$dist = levenshtein($str1,$str2);
$str1len = strlen($str1);
$str2len = strlen($str2);
if($str1len > $str2len)
{
$pct = ($str1len - $dist)/$str1len;
}
else
{
$pct = ($str2len - $dist)/$str2len;
}
$pct = $pct*100;What am I missing from the calculation?
Thanks.
