        ';

        if (preg_match_all('#"url_line":[^"]*"([^"]*)"#', $content, $resultado)) {
            $mp = $resultado[1];   
        } else {
            $mp = ['sin coincidencias']; // este mensaje de error
        }

        foreach ($mp as $nombre) {

            $url = $Link_info;



                if(preg_match($nombre, $url)) {

What you can do is create a variable that contains the result and change if it finds the url. Something like this:

<?php
function External_links($Link_info){

        $content = '
            "url_line":"/youtube.com(.+)v=([^&]+)/";
            "url_line":"/vimeo.com\/([a-z1-9.-_]+)/";
            "url_line":"/facebook.com\/[a-z1-9.-_]+/";
        ';

        if (preg_match_all('#"url_line":[^"]*"([^"]*)"#', $content, $resultado)) {
            $mp = $resultado[1];   
        } else {
            $mp = ['sin coincidencias']; // este mensaje de error
        }
        $result = 'no funciona <br>';
        foreach ($mp as $nombre) {
            if(isset($Link_info)) :
                $url = $Link_info;    

                if(preg_match($nombre, $url)) {                
                    $result = 'yes <br>';
                }

            endif;///
        }
        return $result;
    }

echo External_links('https://www.youtube.com/watch?v=OawLX0jVRVU');
