get day from date in php

[dazed]

I have the code below which I got from the php: mktime manual just edited it to use my own variables but for the day I always get "1".\[code\]$requested_day = $_GET['day'];$requested_month = $_GET['month'];$requested_year = $_GET['year'];if (!empty ($requested_day) || empty ($requested_month) || empty ($requested_year)){ echo $requested_day. " ".$requested_month." ".$requested_year." is on day : ". date("1", mktime(0, 0, 0, $requested_month, $requested_day, $requested_year));}\[/code\]I enter the values and it is outputted as:\[code\]23 09 2010 is on day : 1\[/code\]I think I am having a problem on the "1" I entered on the date, I don't quite understand what this is actually for?Thanks
