PHP Datetime Convert slash to minus - php

Question

I want to convert my datetime 08/11/2013 to 2013-08-11.
I was trying this, but it did not work as it suppose to.
$date = $_POST['gt_date']; // Getting 08/11/2013
$date = explode("/", $date); // Exploding the / character into array
$datetime = $date[2] + '-' + $date[0] + '-' + $date[1];
Any Ideas?

Answer 1

You can pass it to DateTime to format it for you.
$date = new DateTime('08/11/2013');
echo $date->format('Y-m-d');

Answer 2

I don't know what the + does, but changing your code to the following will work:
$datetime = $date[2].'-'.$date[0].'-'.$date[1];
Edit: I guess the + was adding them together. Was the result you were getting 2032?

Answer 3

Here's a function that will return your format so that you don't have to repeat your code.
function makeDateFormat($date) {
$date = $_POST['gt_date'];
$date = explode("/",$date);
$new_date = array($date[2], $date[0], $date[1]);
$date = implode("-",$new_date);
return $date;
}

Answer 4

This issue is caused by the "+" operator, replace it with "." operator. You could use this function:
function formatDate($date) {
$arr = explode("-",$date);
$year = $arr[2];
$month = $arr[1];
$day = $arr[0];
return $year."-".$month."-".$day;
}

Answer 5

Nice function but correction is this below if you want to covert format as well:
echo makeDateFormat('13/02/23','Y-m-d');
function makeDateFormat($date,$date_format) {
$date = explode("/",$date);
$new_date = array($date[2], $date[1], $date[0]);
$date = implode("-",$new_date);
$date=date($date_format,strtotime($date));
return $date;
}
Another way if your require to format date as per your requirement:
$date=explode("/","13/02/23");
$new_date_format=date('Y-m-d',strtotime($date[2].'-'.$date[1].'-'.$date[0]));
