如何更改PHP日期格式

A user selects dating like 22-Sep-2010 from jQuery datepicker.

Is there a php function to convert that date to 22/09/2010? Could strtottime or mktime be used?

$newTime = date('d/M/Y',strtotime($oldTime));

where $oldTime is the value from the date picker.

To convert the date format from dd-mmm-yyyy to dd/mm/yyyy in php,

<?php

$dt='22-Sep-2010';
$dt=date('d/m/Y',strtotime($dt));
echo $dt;

?>

The o/p will be, 22/09/2010
