How do I linkify urls in a string with php?

Question

I have the following string:

"Look on http://www.google.com". 

I need to convert it to:

"Look on http://www.google.com"

The original string can have more than 1 URL string.

How do I do this in php?

Thanks

You can use the following:

$string = "Look on http://www.google.com"; $string = preg_replace(               "~[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]~",               "<a href=\"\\0\">\\0</a>",                $string); 

PHP versions < 5.3 (ereg_replace) otherwise (preg_replace)

lib_autolink does a pretty good job, avoiding pitfalls like extra punctuation after the link and links inside HTML tags:
