This may sound like a stupid question, but: which is faster when using it to extract keywords in a search query in php:

$keyword = preg_split('/[\s]+/', $_GET['search']);

or

$keyword = explode(' ', $_GET['search']);

Explode is faster, per PHP.net

Tip If you don't need the power of regular expressions, you can choose faster (albeit simpler) alternatives like explode() or str_split().
