Hello Friends

If you want to convert plain text in to URLs in JavaScript or PHP. This is good solution for you.

In PHP :

public function makeLinks($str)
{
    $reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
    $urls = array();
    $urlsToReplace = array();
    if(preg_match_all($reg_exUrl, $str, $urls)) {
        $numOfMatches = count($urls[0]);
        $numOfUrlsToReplace = 0;
        for($i=0; $i<$numOfMatches; $i++) {
            $alreadyAdded = false;
            $numOfUrlsToReplace = count($urlsToReplace);
            for($j=0; $j<$numOfUrlsToReplace; $j++) {
                if($urlsToReplace[$j] == $urls[0][$i]) {
                    $alreadyAdded = true;
                }
            }
            if(!$alreadyAdded) {
                array_push($urlsToReplace, $urls[0][$i]);
            }
        }
        $numOfUrlsToReplace = count($urlsToReplace);
        for($i=0; $i<$numOfUrlsToReplace; $i++) {
            $str = str_replace($urlsToReplace[$i], "<a target='_balnk' href=\"".$urlsToReplace[$i]."\">".$urlsToReplace[$i]."</a> ", $str);
        }
        return $str;
    } else {
        return $str;
    }
}

In JavaScript

function makeLinks(text) {
 var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
 return text.replace(exp,"<a target='_blank' href='$1'>$1</a>");
}

Hope it helps.
