PHP check string for html

Question

$content gives the html code like:

<p>text</p>
<p><img ... /></p>
<div class="video">...</div>

or just

<p>text</p>
<p>more text</p>

Also we have a variable:

$video_match = false;

We should turn $video_match to true, if <div class="video"> (exactly this code) exists in $content.

Thanks.

Use:

if (strpos($content, '<div class="video">') !== FALSE)
{
  $video_match = true;
}

Update:

Or more compact version as shown in the comments below:

$video_match = (strpos($content, '<div class="video">') !== FALSE);
