Bug #79176 [Nab]: Since 7 years this function randomly fails when using microtime input

Edit report at https://bugs.php.net/bug.php?id=79176&edit=1 ID: 79176 Updated by: requinix@php.net Reported by: h dot kocznar at compunect dot com Summary: Since 7 years this function randomly fails when using microtime input Status: Not a bug Type: Bug Package: Date/time related Operating System: All PHP Version: 7.4.2 Assigned To: cmb Block user comment: N Private report: N New Comment: You can't rely on the *float* being returned by microtime() to be compatible with the *string* input expected by createFromFormat. This is one of those times that loose typing is a disadvantage: in a strictly-typed language, this wouldn't compile. Protip: sprintf() is good at converting numbers to strings.

I am irritated that such a obvious bug can be ignored, is there no quality control path that makes sure such mistakes are avoided ? ------------------------------------------------------------------------ [2020-01-27 22:34:07] cmb@php.net Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. ------------------------------------------------------------------------ [2020-01-27 17:44:40] h dot kocznar at compunect dot com Wrongly closed bug report: https://bugs.php.net/bug.php?id=64414 ------------------------------------------------------------------------ [2020-01-27 17:44:14] h dot kocznar at compunect dot com Description: ------------ --- From manual page: https://php.net/datetime.createfromformat --- $foo = \DateTime::createFromFormat('U.u', \microtime(true)); This is affecting a huge amount of PHP projects, the function will fail with an error when microtime returns a float without precision values which happens when the time is exactly on that second. This problem was reported 7 years ago and the developer in charge declared the error as "not a bug" because microtime() produces "garbage". Due to the lack of professionalism on his behalf the error is still present in PHP 7.3 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79176&edit=1
