Youtube API – Extract video ID
How do I extract query parameters from an URL string in PHP?

If the input is as follows:

$input = 'http://www.youtube.com/watch?v=ALph_u2iee8&feature=topvideos_music';

And I want to end up with:

$result = 'ALph_u2iee8';

What would be the most rational way to do this in PHP?

Answer 1

PHP has functions to deal with this already.

$input = 'http://www.youtube.com/watch?v=ALph_u2iee8&feature=topvideos_music';

$queryString = parse_url($input, PHP_URL_QUERY);

$queries = array();

parse_str($queryString, $queries);

echo $queries['v'];
