@AbhishekKasera I've edited [my answer](http://stackoverflow.com/a/26774893/3000179) to include `target="_blank"`. Is there anything I've missed? — ʰᵈˑ, Nov 06 '14 at 09:33

function linkify( $string ) {
    return preg_replace( "~\bhttp(s)?://[^<>[:space:]]+[[:alnum:]/]\b~", "<a href=\"\\0\" target=\"_blank\">\\0</a>", $string);
}

its work for https but not work when url contains www ie. "onwww.example.com" – Abhishek Kasera Nov 07 '14 at 11:11
Oh, you've updated the question. – Valentin Rodygin Nov 07 '14 at 11:19
yes, add all requirement, so please suggest me solution for that – Abhishek Kasera Nov 07 '14 at 11:33
Well, it's not clear how you decide how a legitimate third-level domains look like. onwww.somesite.com is a valid domain name, and strictly speaking is not a URL (since there is no schema). – Valentin Rodygin Nov 07 '14 at 11:37

You could use something like;

/\s((http(s)?\:\/\/[a-zA-Z0-9\-\.]+\.)(com|org|net|mil|edu|))/i

With a replace of

<a href="$2">$2<a/>

http://regex101.com/r/nI4gU6/7

Which would make your PHP something like;

 $str = preg_replace(
            '/\s((http(s)?\:\/\/[a-zA-Z0-9\-\.]+\.)(com|org|net|mil|edu))/i',
            ' <a href="${1}" target="_blank">${1}</a>', 
             $s);

For example: https://eval.in/218269

(Note: You'd need to modify it to allow all the other (g)TLD's - however the basic set-up is there)

You could have something like this:

<?php
 function addhttp($url) {
   if (false === strpos($url, '://')) {
      $url = 'http://' . $url;
   }
   return $url;
 }

 $url = "www.google.com";

 var_dump(addhttp($url)); 
 ?>

Then for the URLS where you want to output "http://" you just pass it to the function.

@downvoter - Why the downvote with no explanation? Seems stupid. – Phorce Nov 06 '14 at 08:34
Adding `http://` doesn't automatically make the link clickable. – ʰᵈˑ Nov 06 '14 at 08:36
Wow I did not add `` again, stupid reason. No offence – Phorce Nov 06 '14 at 08:38
