将json日期格式与php一起转换为mm / dd / yy

How do I go about converting date to a readable format like mm/dd/yy? The code below is giving me this: /Date(1335412800000)/

<?php echo '<td>'.$r['effdate'].'</td>'; ?> //displaying this now: /Date(1335412800000)/

Try:

<?php
    $effdate = date('m/j/Y', preg_replace('/[^\d]/','', $r['effdate'])/1000);    
    echo '<td>'.$effdate.'</td>';
?>

I am removing all the non digits.

preg_replace('/[^\d]/','', $r['effdate'])

Dividing it by 1000 as epoch times in JavaScript is x 1000.

/1000

Then I return the formatted date.

date('m/j/Y', ...
