Can not preg_match the following. What am I doing wrong?
===

I want to extract the description of a page that have the following description format. Even though I believe I am correct, I do not get it.

    $file_string = file_get_contents('');
    
    preg_match('/<div class="description">(.*)<\/div>/i', $file_string, $descr);
    $descr_out = $descr[1];
    
    echo $descr_out; 


    <div class="description">
    <p>some text here</p>
    </div>
