Compare two dates in in php

PHP compare dates

I have this code which permits me to grab today's date in this format:

 $today = date("d-m-Y");

Then this query:

while ($row1 = mysql_fetch_array($queryenddate)) { 
$end_date=$row1['end_date'];
}

The end date prints something like : 12-02-2012

How can i compare this two dates? What do i need to do? Thanks

I need to compare the whole date, i mean which is bigger than the other, if today's date is bigger or not — Tao, Sep 25 '12 at 15:43

Convert the date to timestamp, then you can compare the dates easily — Ramya, Sep 25 '12 at 15:46

You can just use DateTime

$today = new DateTime();
$date = DateTime::createFromFormat("d-m-Y", $end_date);

if ($today > $date) {
    // Totaay is more current
}

if ($today->format("m") == $date->format("m")) {
    // they have same month
}

You can also do something like this

$diffrence = $today->diff($date); //enddate is "01-01-2010"
var_dump($diffrence);

Output

object(DateInterval)[3]
  public 'y' => int 2
  public 'm' => int 8
  public 'd' => int 24
  public 'h' => int 0
  public 'i' => int 0
  public 's' => int 0
  public 'invert' => int 1
  public 'days' => int 998

You can use the strtotime () function to convert a date into a number, then you can use for comparisons or opereaciones.

 $today = date("d-m-Y"); 

 $end_date='02-09-2012';

 echo $today;
 echo "<br>".$end_date;

 $diference= (strtotime($end_date)-strtotime($today))/86400;
 $diference= abs($diference); 
 $diference= floor($diference);

  echo "<br>".$diference;
