Php bug与日期有关

when i edit the data and after the submission of that form, i got an error like

ERROR - 2019-05-19 12:40:26 --> Severity: error --> Exception: Call to a member function format() on boolean please help me out of this....

i followed this but its not working Call to a member function format() on boolean in PHP LARAVEL

$datetime = DateTime::createFromFormat('d/m/Y H:i:s', $date . ' ' . $time);
$created_at = $datetime->format('Y-m-d H:i:s');

$record = ['created_at' => $created_at,];

The issue is with the $date or $time string(s) you are trying to pass into DateTime::createFromFormat. They should look similar to the following to work properly:

$date = "15/05/2019";
$time = "10:28:33";

$datetime = DateTime::createFromFormat('d/m/Y H:i:s', $date . ' ' . $time);
$created_at = $datetime->format('Y-m-d H:i:s');

$record = ['created_at' => $created_at,];

print_r($record);

Output:

Array
(
    [created_at] => 2019-05-15 10:28:33
)

The error message explains it all quite detailed.

ERROR - 2019-05-19 12:40:26

Meaning the input is in format "Y-m-d H:i:s"

But your code says 'd/m/Y H:i:s'.

Either your $date variable is wrong or your code is wrong.
Most likely your code should be with format: 'Y-m-d H:i:s'
