youtube embed code with PHP

I have created a blog in php. Users can write something and post it. If this includes a web address then a link automated is created using this :

<?php

//...code

$row['comment'] = preg_replace('@(https?://([-\w.]+[-\w])+(:\d+)?(/([\w-.~:/?#\[\]\@!$&\'()*+,;=%]*)?)?)@', '<a href="$1" target="_blank"><font color="#69aa35">$1</font></a>', $row['comment']);

?>

Using this in posts, text posted successfuly and web address displayed in a link format inside text. Any idea how can I change this, so that if there is a link of youtube, then a youtube frame to be created. For example in facebook, when you post a youtube address, a youtube frame created and posted instead of a link.

I have improved my answer and tested this code:

<?php
// This is your comment string containing the youtube link
$string="Here is a link - https://www.youtube.com/watch?v=LJHFXenOPi4";
// This will remove all links from the input string
preg_match('/[a-zA-Z]+:\/\/[0-9a-zA-Z;.\/?:@=_#&%~,+$]+/', $string, $matches);
foreach($matches as $url){
    // Parse each url within the comment data
    $input = parse_url($url);
    if ($input['host'] == 'youtube.com' || $input['host'] == 'www.youtube.com' ) {
        // If it is a youtube link, then parse the get variables
        parse_str(parse_url($url, PHP_URL_QUERY), $variables);
        // Echo out the iframe with the relevant video ID
        echo '<iframe width="560" height="315" src="//www.youtube.com/embed/'.$variables['v'].'" frameborder="0" allowfullscreen></iframe>';
    }
}
?>

I hope this is what you were looking for, it has worked for me on a few tests

You know the solution don't you? :) If the snippet contains youtube.com URL, then using the same pattern matching you can replace it with a youtube embed tag :)

Basically it will be something like this in pseudo-code.

  • Check the comment pasted to see if youtube URL present (modify the same regex you are using for finding URL, just make it specific for youtube)

  • If yes, then replace it with:

    <iframe type="text/html" width="640" height="385" src="<youtube URL>" frameborder="0"> </iframe>
