How to make plain URL in string clickable in PHP

Hi :)

This is just a quick PHP function to make all plain URL found in a string clickable. Very useful for projects where you want users to be able to click on any links found within text contents. 



 function make_links_clickable($text) {
		// The Regular Expression filter
		$pattern = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
		$text = preg_replace($pattern, "<a href=\"\\0\" rel=\"nofollow\">\\0</a>", $text);

		return $text;

Good luck
