Question

I have the following code:

    $embed_url = str_replace('<iframe width="512" height="288" frameborder="0" scrolling="no" src="', '', $embed_url);
    $embed_url = str_replace('"></iframe>', '', $embed_url);

What happens is the iframe width and height is not fixed values, so they can be any other numbers.

How can I make this works for any width/height?

Thanks.

Edit: What i am trying to get is the src value.

You could use a regular expression:

$embed_url = preg_replace('/<iframe width=".*?" height=".*?" frameborder="0" scrolling="no" src="/', '', $embed_url);

If all you want is to retrieve the value of src, you could use preg_match() instead:

if (preg_match('/<iframe.*?src="(.+?)"/ms', $embed_url, $matches)) {
    $src = $matches[1];
}
