Match string with array

[Xafke]

Hi guys.

 

I wanna write a script that checks how similar a string is to any string in an array.

 

Let's say this is my array:

 

"Name1" => "ABCD"

"Name2" => "ABCDE"

 

And let's say my string is ABC. The script should check how similar ABC is to any string in the array.

So my string matched Name1 for 85%. And it matches name2 for 75%.

 

The script should output the name (in this case name1 or name2) and should output howmuch it matched.

 

I've tried with similar_text() but it can't deal with arrays.

 

Thanks!

can you descibe how this 85% or 75% is calculated?

 

"ABC" has 3 characters, "ABCD" has 4 characters, so i would say they match for 3/4, of 75%

"ABC" has 3 characters, "ABCDE" has 5 characters, so i would say they match for 3/5, of 60%

 

Anw what about if you try to match "ABC" to "XYZABCDE" ?

If you match ABC to XYZABCDE you'll get a match of 54%

This is calculated using PHP's similar_text(). But as sad before, it doesn't work with arrays. (http://php.net/manual/en/function.similar-text.php)

<?php

$text[1]="ABCD";
$text[2]="ABCDE";

$compare="ABC";


foreach ($text as $x) {
        $p="";
        similar_text($compare, $x, &$p);
        $p=round($p,3);
        echo "$x compares to $compare: $p <br>";
}

?>

This does everything that I want. But now there's one more thing I want.

Your script show the result of everything. But I want that the script only show the biggest value. So it only shows the ones with the highest procent ($p in this case)

 

Thanks!

<?php

$text[1]="ABCD";
$text[2]="ABCDE";

$compare="ABC";

$m=0;
foreach ($text as $x) {
        $p="";
        similar_text($compare, $x, &$p);
        $p=round($p,3);
        if ($p>$m) {
                $result="$x compares to $compare: $p <br>";
                $m=$p;
        }
        echo "$x compares to $compare: $p <br>";
}

echo "Max is:";
echo $result;
?>
