Vous pouvez utiliser les fonctions regex et preg_match

preg_match('/src="([^"]+)"/', $iframe_string, $match);
$url = $match[1];

UPDATEsi vous avez une page générée avec php ou en tant que HTML intégré dans un fichier php, vous pouvez utiliser des tampons pour extraire le langage HTML de PHP, puis utiliser regex dessus:

utilisez d'abord ob_start(); au début de votre code de page ou si vous avez du code HTML avant votre php, vous pouvez l'utiliser pour la page entière en ajoutant:

<?php ob_start(); ?>

et le début du fichier php, puis à la fin, vous pouvez obtenir ob buffer en chaîne et appliquer la regex:

<?php ob_start(); ?>
<iframe src="foo.bar"></iframe>

<iframe src="baz"></iframe>
<?php

$output = ob_get_contents();
ob_end_clean();

// find all iframes generated by php or that are in html    
preg_match_all('/<iframe[^>]+src="([^"]+)"/', $output, $match);

$urls = $match[1];
echo $output;

?>

Je cherchais un moyen de prendre des éléments html de l'URL, mais je n'en ai pas trouvé, alors j'ai écrit ceci. une partie de la chaîne que vous voulez.

Mon code HTML est: 

  <div url="doctor.videoLink"><div class="media-youtube-video">
          <iframe src="https://www.youtube.com/embed/YZvJZrfw5oo?rel=0&amp;enablejsapi=1" frameborder="0" allowfullscreen="" id="widget2"></iframe>
</div> 
</div>

Et je retrive src de iframe as:

foreach($kolPro->find('div.video div div iframe') as $youTube)
                            {
                                //$kolsData['you_tube']=$youTube->innertext();
                                preg_match('/src="([^"]+)"/', $youTube, $match);
                                $youtubeLink= $match[1];
                            }
