Use number as variable from curl

Question

I'm using CURL to scrape a progress bar from a website. I already managed to remove everything from the page except the part that I need. It's saved in a array as $progress. This is $progress: <p>Questions Left: <span id="ProgQ">0</span>/25</p>

Now I want to get the get the number 0 in the variable $done and the 25 in the variable #total

I read into this problem, and DOM was suggested, but I'm completly clueless, can anyone explain me step by step how I'm supposed to do this in php?

You wanna do it php or javascript?

In PHP:

$string = '<p>Questions Left: <span id="ProgQ">0</span>/25</p>';
if (preg_match('#<span id="ProgQ">(\d+)</span>/(\d+)#i', $string, $match)) {
   $progress = $match[1];
   $total = $match[2];
}
