Remove warning when parsing datetime with + symbol?

Can anyone explain to me why it is desirable/beneficial for the DateTime class to store a warning that trailing characters were ignored while parsing a date/time string with the + symbol in createFromFormat()? Basic example: https://3v4l.org/Sod9o $dt = DateTime::createFromFormat('h:i:A+', '01:31:PM - 03:00:PM'); var_export(DateTime::getLastErrors()); Output: array ( 'warning_count' => 1, 'warnings' => array ( 8 => 'Trailing data', ), 'error_count' => 0, 'errors' => array ( ), ) Docs: https://www.php.net/manual/en/datetimeimmutable.createfromformat.php#:~:text=If%20this%20format,instead I mean, why would I welcome the warning when I explicitly stated that I want to ignore the trailing characters? If there is longer a good reason for the warning, can it be removed from the language? If there is some benefit from having this feedback, then could it be moved to be a new property of the datetime object? To programming purists who hate generating notices and warnings, this probably feels like a wart on the language. Please enlighten me. mickmackusa
