Listing PDF files in dir with PHP 7.2

Question

The function below lists all PDF files in choosen directory. Also reads and print out the song title inside the PDF (they are all songs). The script works like a charm in PHP 5.6 but not in PHP 7.2. I have to upgrade to 7.2 because of my hosting company.

function listPDF($dirtoread) {

if($handle = opendir("pdf/".$dirtoread)) {

//ny
$theFiles = array();

$count = 0;
while($currentfile = readdir($handle)) {

    if(!ereg('^\.',$currentfile)) {
        $theFiles[$count] = $currentfile;
        $count++;
    }
}

sort($theFiles,SORT_STRING);

for ($i=0; $i < count($theFiles); $i++){

        $string = file_get_contents("pdf/".$dirtoread."/".$theFiles[$i]);
        $start = strpos($string, "<dc:title>") + 10;
        $length = strpos(substr($string, $start), '</dc:title>');

        if ($length) {
            $title = strip_tags(substr($string, $start, $length));
        }


        echo "<a  class='popup gallery pdf' rel='width:700;height:600'  href='pdf/".$dirtoread."/".$theFiles[$i]."' style='text-decoration:none; line-height:2em;'><img src='pdf/pdf_small.gif' align='bottom' border='0'> ".$title."</a><br>";


}
closedir($handle);
}
}
