Edit report at http://bugs.php.net/bug.php?id=54139&edit=1 ID: 54139 User updated by: ryan_a_martin at yahoo dot com Reported by: ryan_a_martin at yahoo dot com Summary: All date acceptance functions should cross-reference checkdate() Status: Open Type: Documentation Problem Package: Documentation problem Operating System: N/A PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Test script was invalid: ---------- <?php print_r(date_parse('2009-02-30')); echo strtotime('2010-11-31'); ?> Previous Comments: ------------------------------------------------------------------------ [2011-03-02 15:54:58] ryan_a_martin at yahoo dot com Description: ------------ Since PHP functions like strtotime, mktime, and date_parse do not catch well-formatted but invalid dates like 2009-02-30 and 2010-11-31, it is necessary to use checkdate() to catch them. All documentation pages that document functions intended for accepting Gregorian dates should list checkdate() in their "See Also" sections. Test script: --------------- print_r(date_parse('2009-02-30')); print_r(strtotime('2010-11-31')); Expected result: ---------------- For date_parse, error_count > 0 and an error thrown. For strtotime, an error thrown, not a UNIX timestamp. Since this does not happen, we need the documentation to make clear that these functions do not validate Gregorian dates, and that a call to checkdate() is required to catch such dates. Actual result: -------------- Array ( [year] => 2009 [month] => 2 [day] => 30 [hour] => [minute] => [second] => [fraction] => [warning_count] => 0 [warnings] => Array ( ) [error_count] => 0 [errors] => Array ( ) [is_localtime] => ) 1291179600 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54139&edit=1
