      2011-05-27T11:21:23

How can do with date function to get this date format:

Answer 1

If parsing the string returned by microtime makes you vomit in your mouth, and you don't want multiple distinct timestamps munged together into your output, you can do this:

$unow = microtime(true);
sprintf("%s.%06d%s", date("Y-m-d\TH:i:s", $unow), ($unow - floor($unow))*1e6, date("P", $unow));
