Linkify PHP text

Hi I have a field from a database that contains http links as well as normal text.

I need to find out a way to display this information using PHP to show Text and a link when applicable.

the following is my sql query:

  $sql =
   "select bw_supporting_doc
    from cm3rm2 with(nolock)
    where number = '$id'";

the output of this sql statement is:

Please find below the link to the FSS: http://blahblack.html

I need to display the http://blahblack.html as a link at the moment it is displaying as normal text.

Thanks!

Answer 1

function hyperlink($text){
    $text = preg_replace("#(http://)+?([.]?[a-zA-Z0-9_/-])*#", "<a href=\"\\0\" target=\"_blank\">\\0</a>", $text);
    return $text;
}

this might do the job

example usage: $str = 'this is a random string which contains a link http://www.yahoo.com';

echo hyperlink($str);
