<?php

$curdate=mktime(0,0,0,date("d"),date("m"),date("Y"));

  echo $curdate;

Are you trying to get the previous month?

 

If so, just use mktime's ability to subtract...

 

echo "Today: " . date("Y/m/d") . "<br />";
echo "Last month: " . date("Y/m/d", mktime(0, 0, 0, date("m") - 1, date("d"), date("Y")));

I'm not sure what you're after, but your code looks like it's trying to find the date 30 days prior to the current date. If so, you could use any number of options. Here are a couple to get you started:

<?php
// Option 1: strtotime()
$time = strtotime("today -30 day");
echo date('Y-m-d', $time);

// Option 2: time() or mktime()
$day   = 60 * 60 * 24;
$time  = time(); // or $time = mktime();
$time -= $day * 30;
echo date('Y-m-d', $time);
?>

 

If this isn't what you're after, try telling us what yours is actually showing and what you want it to show. That will help us debug with you.

Imagine it was the 1st month (ie January), then the month parameter would have 0 (which is not a valid month). Also, not all months got the same amount of days.

Sorry, I really didn't specify what i wanted.

 

You're right,I need to find the date 30 prior to the current.

Thank you for your help.With your assistance it works.

But I can't understand why my code won't work  :-\

 

Anyway,thank you

I just realized you have your month and day switched in your mktime() call. That's why it's giving you a date sometime in 2009. Remember, though, with mktime(), it will default to the current date, so you don't have to provide the year, month and day at all:

<?php
$curdate = mktime(0,0,0,date('m'),date('d'),date('Y')); // notice the switch from yours
?>

mktime is designed for such an occurrence.  Should that happen, it will go to the previous year's December...
