回答1:

$newDate = date('r', strtotime('2011-08-01 04:01:45'));

回答2:

use the strtotime function in php to parse the date string and then the date function to print it in whatever format you'd like.

<?php

$orig = "2011-08-01 04:01:45";

$timestamp = strtotime($orig);

echo date("D, d M Y H:i:s O",$timestamp);
?>

I know that this isn't going to solve your problem but a really fast method of using dates and information is to store the time using a unix time stamp. This is an integer value of seconds counting from the time (1970 -1 second).

It will allow you to format dates in a much simpler manner using something like:

<?php date('d-m-Y', $unixTimeStamp); ?>

This method is also much faster when it comes to comparing times.
