note 130478 added to function.strtotime

An interesting gotcha I found today which took a second to track down. strtotime will return false with an empty string, or something that is clearly not a date. But whitespace returns the current time. <?php $date = ''; $utc = strtotime($date); var_dump($date); var_dump($utc); $date = 'notADate'; $utc = strtotime($date); var_dump($date); var_dump($utc); $date = ' '; $utc = strtotime($date); var_dump($date); var_dump($utc); ?> Will return: string(0) "" bool(false) string(8) "notADate" bool(false) string(1) " " int(1757608141) ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.84.18 (proxied: 206.195.188.253) ---- Manual Page -- https://php.net/manual/en/function.strtotime.php Edit -- https://main.php.net/note/edit/130478 Del: integrated -- https://main.php.net/note/delete/130478/integrated Del: useless -- https://main.php.net/note/delete/130478/useless Del: bad code -- https://main.php.net/note/delete/130478/bad+code Del: spam -- https://main.php.net/note/delete/130478/spam Del: non-english -- https://main.php.net/note/delete/130478/non-english Del: in docs -- https://main.php.net/note/delete/130478/in+docs Del: other reasons-- https://main.php.net/note/delete/130478 Reject -- https://main.php.net/note/reject/130478 Search -- https://main.php.net/manage/user-notes.php
