| Version | Description |

        return the documented array structure. | 
Example #1 DateTimeImmutable::getLastErrors() example
<?php
try {
    $date = new DateTimeImmutable('asdfasdf');
} catch (Exception $e) {
    // For demonstration purposes only...
    print_r(DateTimeImmutable::getLastErrors());
    // The real object-oriented way to do this is
    // echo $e->getMessage();
}
?>
The above examples will output:
Array
(
   [warning_count] => 1
   [warnings] => Array
       (
           [6] => Double timezone specification
       )
   [error_count] => 1
   [errors] => Array
       (
           [0] => The timezone could not be found in the database
       )
)
The indexes 6, and 0 in the example output refer to the character index in the string where the error occurred.
