How to format a semicolon separated output

[dragonstyleGG]

Hi,

I have a output (from a TV) like this:

test1;test2;test3;

How can I output it like:

<span class="tag">test1</span><span class="tag">test2</span><span class="tag">test3</span>

For example with a custom snippet:

[[formatTv? &tvValue=`[[*myTv]]`]]

Snippet formatTv:

<?php
$values = explode(';', $tvValue);
$output = '';
foreach($values as $value){
    $output .= '<span class="tag">' . $value . '</span>';
}
return $output;

Thank you very much. That worked.
I changed the code a bit to make a custom output filter:

$values = explode(';', $input);
$output = '';
foreach($values as $value){
    $output .= '<span class="tag">' . $value . '</span> ';
}
return $output;

and then call it like so:

[[+tv.myTV:explodeBySemi]]
