How do I Convert Date Format in PHP

    RahulBy 1 Min ReadUpdated:

    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.

    1
    2
    3
    4
    $origDate = "2019-01-15";
     
    $newDate = date("m-d-Y", strtotime($origDate));
    echo $newDate;

    Output:

    01-15-2019

    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.

    1
    2

    4
    $origDate = "2019-01-15";
     
    $newDate = date("d-m-Y", strtotime($origDate));
    echo $newDate;

    Output:

    15-01-2019

    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).

    5
    $origDate = "15/01/2019";
     
    $date = str_replace('/', '-', $origDate );
    $newDate = date("Y-m-d", strtotime($date));
    echo $newDate;

    Output:

    2019-01-15

      Hello Paul, this is a great tutorial but I have question regarding my current problem in MySQL and PHP in finding the difference between 2 dates(variables: start date and end date). MySQL date format is YYYY-mm-dd while in bootstrap is mm/dd/YYYY. I want to calculate the difference between two dates from MySQL and display the output from PHP. I hope you could help me on this Paul ?

      Great article however what do you do if the original date is in the format of a posted string ie let’s say “15/01/2019” .

      $origDate = $_POST[‘Date1’];

      $date = str_replace(‘/’, ‘-‘, $origDate );
      $newDate = date(“Y-m-d”, strtotime($date));
      echo $newDate;
