php将unicode http链接转换为可点击

Question

i have unicode link needed to be turn into links.

Is it possible to change unicode into clickable?

Currently i'm using this piece of code to turn link into clickable

function clickable_link($text)
{
$ret = ' ' . $text;
$ret = preg_replace("#(^|[
 ])([\w]+?://[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a class=\"hrefLink\" href=\"\\2\" target=\"_blank\">\\2</a>", $ret);
$ret = preg_replace("#(^|[
 ])((www|ftp)\.[\w\#$%&~/.\-;:=,?@\[\]+]*)#is", "\\1<a class=\"hrefLink\" href=\"http://\\2\" target=\"_blank\">\\2</a>", $ret);
$ret = preg_replace("#(^|[
 ])([a-z0-9&\-_.]+?)@([\w\-]+\.([\w\-\.]+\.)*[\w]+)#i", "\\1<a href=\"mailto:\\2@\\3\">\\2@\\3</a>", $ret);
$ret = substr($ret, 1);
return $ret;
} 

Any help would be deeply appreciated.
