将datetime json字符串转换为日期

I got JSON object with date property like this

"date": 1402680443

How can I convert it with PHP to show just the date in Jan 00 0000 format ?

You can use function date(); date("Y-m-d H:i:s", 1402680443);

If you receive json and need converting date, try this:

$date = new DateTime();
$date->setTimestamp(1402680443);
echo $date->format('Y-m-d H:i:s');

Set to setTimestamp() method date value from your json object.
