Yes, you're right about that. 10 years ago I went to a seminar were Rasmus Lerforf was speaking and asked him exactly that question. The single qoutes are preferred and are way faster because it doesn´t have to parse the string, only the glued variables. Also we discussed that if you´re doing a bunch of HTML code it's considerably faster to do: <tr> <td><?= $data ?></td> </tr> Than print " \n\t<tr> \n\t\t<td>$data</td> \n\t</tr>"; or print ' <tr> <td>'.$data.'</td> </tr>'; I remember benchmark testing it afterwards back then and there was clearly a difference. -- Kind regards Kim Emax - masterminds.dk -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
