Question

I have a youtube video embed code that looks like this:

<iframe width="560" height="315" src="http://www.youtube.com/embed/XGdfNb15h9o" frameborder="0" allowfullscreen></iframe>

I need to add the following (it gets rid of related video suggestions):

?rel=0

to the end of each url in the embed code. So in the above example, the final code should look like this:

<iframe width="560" height="315" src="http://www.youtube.com/embed/XGdfNb15h9o?rel=0" frameborder="0" allowfullscreen></iframe>

The embed code is stored in a variable called $embed_code. How can I transform the embed code to hav the ?rel=0 applied to it?

Answer 1

If everything else is staying constant you can use str_replace instead which will be faster.

    <?php
$iframe = '<iframe width="560" height="315" src="http://www.youtube.com/embed/XGdfNb15h9o" frameborder="0" allowfullscreen></iframe>';
$pattern = '" frameborder="0"';
$replace = '?rel=0" frameborder="0"';

$iframe = str_replace($pattern,$replace, $iframe);

echo $iframe;

?>
