Rename array index in PHP

Question

I want to explode a date but want to rename default index 0,1,2 to year, month, day respectively, I tried but I am not able to figure it out. Here's what am doing right now.

$explode_date = explode("-", "2012-09-28");
echo $explode_date[0]; //Output is 2012
echo $explode_date[1]; //Output is 09
echo $explode_date[2]; //Output is 28

what I want

echo $explode_date['year']; //Output is 2012
echo $explode_date['month']; //Output is 09
echo $explode_date['day']; //Output is 28

Thanks..

@V413HAV You might want to check out PHP's DateTime class (built-in) since it can handle dates and times gracefully. It's also supported by PHP, so why not use something that's already been built, rather than re-inventing the wheel? — Stegrex, Jul 13 '12 at 09:25
@Stegrex As I told complex857 I need a solution for php version < 5 and by the way am not that good with OOP ;) still need to learn it. — Random Guy, Jul 13 '12 at 09:29

use array_combine:

$keys = array('year', 'month', 'day');
$values = explode("-", "2012-09-28");
$dates = array_combine($keys, $values);

list($year, $month, $day)  = explode("-", "2012-09-28");
$x = compact('year', 'month', 'day');


var_dump($x);

array
  'year' => string '2012' (length=4)
  'month' => string '09' (length=2)
  'day' => string '28' (length=2)

You'll have to map out the associations:

$explode_date = explode("-", "2012-09-28");
$new_array['year'] = $explode_date[0];
$new_array['month'] = $explode_date[1];
$new_array['day'] = $explode_date[2];

Or, you can use PHP's built in DateTime class (probably better since what you want to do has already been done):

http://www.php.net/manual/en/book.datetime.php

$date = new DateTime('2012-09-28');
echo $date->format('Y');
echo $date->format('m');
echo $date->format('d');
