This little PHP function will find urls and email addresses in a block of text and turn them into hyperlinks and mailto: anchors respectively.



function makeLinks($sourceText) {

  $destText = preg_replace( "/([_a-zA-Z0-9-]+)(\.[_a-zA-Z0-9-]+)*@([a-zA-Z0-9-]+)(\.[a-zA-Z0-9-]+)*(\.[a-zA-Z]{2,4})/", '\\0',$sourceText);

  $destText = preg_replace_callback('/\bhttp[^\s]+/',create_function('$matches', 'return "" . preg_replace("#(\.|/)#", "$1", $matches[0]) . "";'),$destText);

  return $destText;

}
