Wie bekomme ich URL vom iFrame mit PHP

Question

Wie bekomme ich die Youtube-URL von dem folgenden Link?

<iframe title="YouTube video player" width="640" height="390" 
src="http://www.youtube.com/embed/VvJ037b_kLs" 
frameborder="0" allowfullscreen></iframe> 

Answer 1

können Sie verwenden regex und preg_match Funktion

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

Answer 2

<?php 
function getHtmlElement($html,$startOfElement,$endOfElement) 
{ 
    $startingPosition = strpos($html, $startOfElement); 
    $endPosition = strpos($html, $endOfElement,$startingPosition); 
    $foundElement = substr($html, $startingPosition,$endPosition); 

    return $foundElement; 
} 

    $html = file_get_contents('http://www.youtube.com/'); 
    $startOfElement = '<div id="guide"'; 
    $endOfElement = "<"; 

    $myElement = getHtmlElement($html,$startOfElement,$endOfElement); 

    echo $myElement; 

ich nach einem Weg suchen, HTML-Elemente aus URLs zu nehmen, aber ich fand nicht, ein so schrieb ich this.It Werke genau wie im Beispiel gezeigt. Nachdem Sie das Element erhalten haben, können Sie die gleiche Logik anwenden wie die Funktion, die ich geschrieben habe, um einen Teil der gewünschten Zeichenfolge zu erhalten.

$tmpDoc = new DOMDocument(); 

# Dirty hack to support utf-8 with loadHTML 
# http://php.net/manual/en/domdocument.loadhtml.php#95251 
@$tmpDoc->loadHTML('<?xml encoding="UTF-8">' . $url); 
foreach ($tmpDoc->childNodes as $item) { 
    if ($item->nodeType == XML_PI_NODE) { 
     $tmpDoc->removeChild($item);// remove hack 
    } 
} 
$tmpDoc->encoding = 'UTF-8'; // insert proper 

$body = $tmpDoc->getElementsByTagName('body'); 

if (! $body->length) { 
    return null;

$nodes = $body->item(0)->childNodes; 

if (empty($nodes)) {

Answer 5

Mein html webcode ist:

<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> 

Und ich retrive src von iframe wie:

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