datetime - PHP Fatal error: Call to a member function format() on boolean

Question

Crashes on:

<?php 
    $date = "13-06-2015 23:45:52";
    echo Datetime::createFromFormat('d-m-Y h:i:s',  $date)->format('Y-m-d h:i:s'); 
?>

PHP Fatal error: Call to a member function format() on boolean

But with other dates works well:

<?php 
    $date = "10.06.2015 09:25:52";
    echo Datetime::createFromFormat('d-m-Y h:i:s',  $date)->format('Y-m-d h:i:s');
?>

Wrong format?

Answer 1

Neither example work as you have multiple errors:

1. You forgot your second parameter to Datetime::createFromFormat()
2. h:i:s should be H:i:s
3. Your date in the second example is separated by a . not a -

Fixes:

<?php 
    $date = "13-06-2015 23:45:52";
    echo DateTime::createFromFormat('d-m-Y H:i:s', $date)->format('Y-m-d h:i:s'); 

    $date = "10.06.2015 09:25:52";
    echo DateTime::createFromFormat('d.m.Y H:i:s', $date)->format('Y-m-d h:i:s');
?>
