Changing a date format in PHP

hi

I can not figure out how to format a date in PHP.

I have a form where a user will enter 01/10/2011 15:00

I have a php script which is calling the date

$date = $_POST["date"];

I then can call this no problem, but I want to format the date to 01102011PM

I have tried

$date = $_POST["date"];
$booking = date('ddmmyyy',$date);

But this comes back 01011970

Please could someone assist?

 

preg_replace("/\//",$_POST['date']);

but sanitize your inputs.

 

Thank you , preg_replace('/\//','',$_POST['date']) this is the exact string ) which works.
