PHP url create from string

Question

I would like to check a string and convert all the substrings that could be potential links inside the original string like http://www.google.com, or www.google.com, replaced with <a href='http://www.google.com'>http://www.google.com</a> so that i can create real links from them.

How can i do this?

@alexn: Not quite, as Alexander wants to also linkify URLs without http://. — Tim Pietzcker

you can create the HTML links by calling the following function in PHP:

$stringToCheck = 'http://www.google.com, or www.google.com';
$stringWithHTMLLinks = '';

$stringWithHTMLLinks = preg_replace('/\b((https?|ftp|file):\/\/|www\.|ftp\.)[-A-Z0-9+&@#\/%?=~_|!:,.;]*[A-Z0-9+&@#\/%=~_|]/si', '<a href="\0">\0</a>', $stringToCheck);

the h*ttp://www.google.com works fine but the www.google.com gives me localhost/migo2/www.google.com on localhost

Use this regex provided on Daring Fireball to match an URL.

Here is the full version (IT IS LONG):

(?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s

!()[]{};:'".,<>?«»“”‘’]))`

Here is the shortened version (only matching http addresses):

(?i)\b((?:https?://|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s

!()[]{};:'".,<>?«»“”‘’]))`

Also from Daring Fireball's page above:

Update: A few readers have asked what the licensing terms are for using this pattern in their own code. This pattern is free for anyone to use, no strings attached. Consider it public domain.
