php trim away undesired texts
<p>I have the following data in mysql database which is an iframe from u-tube:-</p>

<pre><code>`&lt;iframe width="560" height="315" src="http://www.youtube.com/embed/Om2fabTIKE4" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;`
</code></pre>

<p>Nevertheless, in the php codes, a present phase is present for the above iframe, in which I just need Om2fabTIKE4 as the variable to be filled in.</p>

<pre><code>I would like to ask, is there any way that I can trim away
</code></pre>

<p><code>&lt;iframe width="560" height="315" src="http://www.youtube.com/embed/</code></p>

<p>and</p>

<p><code>frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;</code></p>
