Question

I have a form where I can input two words then compare the levenshtein score, that works fine.

I want to be able to compare 1 word with a string of words delimited by ", ". The whole lot then needs to echo out. Here’s what I have so far:

Levenstein for <b><?php echo $_POST["source"]; ?></b> and <b><?php echo $_POST["target"]; ?></b>:

<?php
$string5 = $_POST["source"];
$string6 = $_POST["target"];
$array6 = explode(', ',$string6); 
    
echo levenshtein("$string5","$array6");
?>

You’d use a foreach loop (a for loop would be fine too). Try:

Levenstien for <b><?php echo $_POST["source"]; ?></b> and <b><?php echo $_POST["target"]; ?></b>:

<?php
$string5 = $_POST["source"];
$string6 = $_POST["target"];
$array6 = explode(', ',$string6); 

foreach ($array6 as $derp)
{
    echo $string5, "/", $derp, ": ", levenshtein($string5, $derp), "<br>";
}

?>

To output in order by score, use this:

Levenstien for <b><?php echo $_POST["source"]; ?></b> and <b><?php echo $_POST["target"]; ?></b>:

<?php
$string5 = $_POST["source"];
$string6 = $_POST["target"];
$array6 = array_map('trim', explode(',',$string6));
$doop = array();

foreach ($array6 as $derp)
{
    doop[$derp] = levenshtein($string5, $derp);
}

arsort($doop); // sorts highest element first

foreach ($words as $key => $value)
{
    echo sprintf('%s / %s: %s<br />', $string5, $key, $value);
}
