I have a website that gets fed data from a local MLS. I put together PHP to grab the title of the page which contains the address & MLS # of the current property, and create schema for it. I also collect some information from meta and compase the image url based on known information. However, when I use the code below, my site becomes slow and starts to crash. I have put the script below just above the ending body tag, below wp_footer(). I would feel better about myself if the problem was something complex, but it is probably something dumb. Thank you in advance.

        $path="http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];//gets url of current page
$tags = get_meta_tags($path); //retrieves an array of all meta name tags
$description= $tags['og:description']; // tag containing the property descriion
        $the_address= explode(",",ucwords(strtolower(get_the_title())) ); //get post title, parse address parts
        $street=$the_address[0];
        $city =$the_address[1];
        $add2 = explode ("(", $the_address[2]);
        $state = strtoupper(substr($the_address[2],1,2));
        $zip = substr($the_address[2],4,5);
        $mls= substr($the_address[2],17,8); echo $mls;
$img_url = "/".substr($mls,5,3). "/f_". $mls. ".jpg";
$price="";
