Convert a date from yyyy-mm-dd to dd-mm-yyyy format

How do I Convert Date Format in PHP

This tutorial uses PHP strtotime() and date() functions to convert date time format. For example you have stored a date YYYY-MM-DD format in a variable and need to change this to MM-DD-YYYY format.

We can achive this by converting date first to seconds using strtotime() function. After that reconstruct date to any format using date() function. Below is few examples of conversion:

1. Change YYYY-MM-DD => MM-DD-YYYY

Here we have date yyyy-mm-dd (“2019-01-15”) format and converting it to mm-dd-yyyy (“01-15-2019”) format.

2. Change YYYY-MM-DD => DD-MM-YYYY

Here we have date yyyy-mm-dd (“2019-01-15”) format and converting it to dd-mm-yyyy (“15-01-2019”) format.

3. Change DD/MM/YYYY => YYYY-MM-DD

If you have slashes in date format like “15/01/2019” and need to convert / with hyphens (-). The following example will help you to convert DD/MM/YYYY (“15/01/2019”) to YYYY-MM-DD (2019-01-15).

How to Convert a Date Format in PHP

Check out several possible conversion cases below.

Convert YYYY-MM-DD to DD-MM-YYYY

Imagine, that you have kept date 2020-05-15 in MM-DD-YYYY format and intend to change it to 15-05-2020 in the DD-MM-YYYY format.

 $orgDate = "2020-05-15"; $newDate = date("d-m-Y", strtotime($orgDate)); echo "New date format is: " . $newDate . " (MM-DD-YYYY)"; ?>

Convert YYYY-MM-DD to MM-DD-YYYY

Now, imagine having a date 2020-05-15 in YYYY-MM-DD format. Let’s convert it to 05-15-2020 (MM-DD-YYYY) like this:

 $orgDate = "2020-05-15"; $newDate = date("m-d-Y", strtotime($orgDate)); echo "New date format is: " . $newDate . " (MM-DD-YYYY)"; ?>

Convert DD-MM-YYYY to YYYY-MM-DD

In this section, consider having a date 15-05-2020 in DD-MM-YYYY format. Below, you can see how to convert it to 2020-05-15 (YYYY-MM-DD) format:

 $orgDate = "15-05-2020"; $newDate = date("Y-m-d", strtotime($orgDate)); echo "New date format is: " . $newDate . " (YYYY-MM-DD)"; ?>

Convert DD-MM-YYYY to YYYY/MM/DD

Now, suppose having a date 15-05-2020 in DD-MM-YYYY format. It is separated by dash (-) sign. Let’s try converting it to 2020/05/15 (YYYY/MM/DD) format, separated by slash(/) .

 $orgDate = "15-05-2020"; $date = str_replace('-"', '/', $orgDate); $newDate = date("Y/m/d", strtotime($date)); echo "New date format is: " . $newDate . " (YYYY/MM/DD)"; ?>

In this section, you will figure out how to transform date format MM-DD-YYYY to YYYY-DD-MM, as well as12 hours time clock to 24 hours.

 $date = "05/15/2020 5:36 PM"; //converts date and time to seconds $sec = strtotime($date); //converts seconds into a specific format $newdate = date("Y/d/m H:i", $sec); //Appends seconds with the time $newdate = $newdate . ":00"; // display converted date and time echo "New date time format is: " . $newDate; ?>
