note 85321 added to function.checkdate

I wrote a simple function to converter datetime to UNIX timestamp. If the input time with error format, the function will return current timestamp. function datetime2timestamp($datetime) { $datetime = str_replace('-', ' ', $datetime); $datetime = str_replace('/', ' ', $datetime); $datetime = str_replace(':', ' ', $datetime); $array = explode(' ', $datetime); $year = $array[0]; $month = $array[1]; $day = $array[2]; $array[3] ? $hour = $array[3] : $hour = '00'; $array[4] ? $minute = $array[4] : $minute = '00'; $array[5] ? $second = $array[5] : $second = '00'; if (preg_match("/^(\d{4}) (\d{2}) (\d{2}) ([01][0-9]|2[0-3]) ([0-5][0-9]) ([0-5][0-9])$/", "$year $month $day $hour $minute $second", $matches)) { if (checkdate($matches[2], $matches[3], $matches[1])) { return mktime(intval($hour), intval($minute), intval($second), intval($month), intval($day), intval($year)); } else { return time(); } } else { return time(); } } ---- Server IP: 140.113.54.119 Probable Submitter: 60.199.247.200 ---- Manual Page -- http://www.php.net/manual/en/function.checkdate.php Edit -- https://master.php.net/note/edit/85321 Del: integrated -- https://master.php.net/note/delete/85321/integrated Del: useless -- https://master.php.net/note/delete/85321/useless Del: bad code -- https://master.php.net/note/delete/85321/bad+code Del: spam -- https://master.php.net/note/delete/85321/spam Del: non-english -- https://master.php.net/note/delete/85321/non-english Del: in docs -- https://master.php.net/note/delete/85321/in+docs Del: other reasons-- https://master.php.net/note/delete/85321 Reject -- https://master.php.net/note/reject/85321 Search -- https://master.php.net/manage/user-notes.php
