    Try the following instead:

    $test = '<script type="text/javascript"> [CONTENT HERE] </script>';
    $start = preg_quote('<script type="text/javascript">', '/');
    $end = preg_quote('</script>', '/');
    
    preg_match("/$start(.*?)$end/", $test, $matches);
    
    var_dump($matches);
    

    Output:

    array (size=2)
      0 => string '<script type="text/javascript"> [CONTENT HERE] </script>' (length=56)
      1 => string ' [CONTENT HERE] ' (length=16)
    

    The problem is actually the spaces after and before / in the preg_match
