title: How can I remove a spcific html meta tag with php?
body: <p>I would like to this:<br>
  <strong>If</strong> php found this specific meta tag in the html source,then delete from header:</p>
  
  <pre><code>&lt;meta property="og:video:type" content="application/x-shockwave-flash" /&gt; &lt;meta property="og:video" content="https://www.neocsatblog.info/jwplayer/player.swf?file=&amp;autostart=true&amp;skinName=newtube&amp;skinURL=https%3A%2F%2Fneocsatblog.info%2Fskinning-sdk%2Ffive%2Fnewtube%2Fnewtube.xml" /&gt;
  </code></pre>
  
  <p>I tryed this way, but dosen't work:</p>
  
  <pre><code>if ( $fullmeta == '&lt;meta property="og:video:type" content="application/x-shockwave-flash" /&gt; &lt;meta property="og:video" content="https://www.neocsatblog.info/jwplayer/player.swf?file=&amp;autostart=true&amp;skinName=newtube&amp;skinURL=https%3A%2F%2Fneocsatblog.info%2Fskinning-sdk%2Ffive%2Fnewtube%2Fnewtube.xml" /&gt;') {
       $fullmeta="";  
     }
  </code></pre>
  
  <p>The full codeblock where the full meta is declareted:</p>
  
  <pre><code>&lt;? 
   $video_url = get_field('video_urlasd');
  if (isset($video_url) &amp;&amp; $video_url !== "https://") {
    $meta1='&lt;meta property="og:video:type" content="application/x-shockwave-flash" /&gt;';
    $skinURL="https://neocsatblog.info/skinning-sdk/five/newtube/newtube.xml";
    $meta2=' &lt;meta property="og:video" content="https://www.neocsatblog.info/jwplayer/player.swf?file='.urlencode($video_url).'&amp;autostart=true&amp;skinName=newtube&amp;skinURL='.urlencode($skinURL).'" /&gt;';
    $fullmeta=$meta1.$meta2;
    echo $fullmeta;
    }else{
        echo chop($fullmeta,"asd");
    }
     if ( $fullmeta == '&lt;meta property="og:video:type" content="application/x-shockwave-flash" /&gt; &lt;meta property="og:video" content="https://www.neocsatblog.info/jwplayer/player.swf?file=&amp;autostart=true&amp;skinName=newtube&amp;skinURL=https%3A%2F%2Fneocsatblog.info%2Fskinning-sdk%2Ffive%2Fnewtube%2Fnewtube.xml" /&gt;') {
       echo $fullmeta="";  
     }
    ?&gt;
  </code></pre>
  
  <p>I don't know why, because on the HTML source I found it and looks like same as I copied!</p>
