I am currently utilizing PHP 7.2 for my project and attempting to generate a date from a string through the following process:
$dateString = '2018-12-31T01:01:01+00:00';
$converted = DateTime::createFromFormat(DATE_ATOM), $dateString);
The code snippet mentioned above is functioning properly and yielding the expected output.
However, an issue arises when I interchange the day and month within the provided date string, as depicted below:
$dateString = '2018-31-12T01:01:01+00:00';
$converted = DateTime::createFromFormat(DATE_ATOM), $dateString);
I had anticipated that this second scenario would result in false, but contrary to my expectations, an actual datetime value of 2020-07-12 01:01:01.000000 is returned.
This poses a challenge since I am unable to distinguish whether the second date is valid or invalid, given that the system has accepted it. Consequently, I will be storing inappropriate data in my database unknowingly.
Could this behavior potentially be classified as a bug within PHP 7.2?
