PHP – Auto Convert URLs to Links in a Block of Text

Whether you’re creating your own custom blog, tweaking a CMS or building a plugin this is one block of code that can come in very handy. I’ve used this many times over the years and it has always served me well. I will admit, I am terrible with regular expressions and found this a while back, so I can take no credit for it. Usually I use something like txt2re when I a cutomer regular expression.

$pattern = "@\b(https?://)?(([0-9a-zA-Z_!~*'().&=+$%-]+:)?[0-9a-zA-Z_!~*'().&=+$%-]+\@)?(([0-9]{1,3}\.){3}[0-9]{1,3}|([0-9a-zA-Z_!~*'()-]+\.)*([0-9a-zA-Z][0-9a-zA-Z-]{0,61})?[0-9a-zA-Z]\.[a-zA-Z]{2,6})(:[0-9]{1,4})?((/[0-9a-zA-Z_!~*'().;?:\@&=+$,%#-]+)*/?)@";

$text = preg_replace($pattern, '\0', $text_raw);

Hopefully someone else finds it useful
