note 79146 added to language.types.string

<?php $a = '2007-11-05 15:17:49'; $b = '2007-11-05 15:17:48'; $bool = $a > $b; var_dump($bool); //bool(true) ?> works correctly since there is a comparing between strings. The comparisson is done on the last number/letter (since thats the only thing that is difference in the string) and that is in this case: the 9 and 8. 8 > 9 = true if you want to compare the string as pure numbers then you must type cast it to numbers or type juggle it: <?php $a = '2007-11-05 15:17:49'; $b = '2007-11-05 15:17:48'; $bool1 = ($a + 0) > ($b + 0); // 2007 > 2007 $bool2 = (int) $a > (int) $b; // 2007 > 2007 $bool3 = intval($a) > intval($b); // 2007 > 2007 var_dump($bool1,$bool2,$bool3); //bool(false) ?> ---- Server IP: 85.12.26.134 Probable Submitter: 82.171.170.147 ---- Manual Page -- http://www.php.net/manual/en/language.types.string.php Edit -- https://master.php.net/note/edit/79146 Del: integrated -- https://master.php.net/note/delete/79146/integrated Del: useless -- https://master.php.net/note/delete/79146/useless Del: bad code -- https://master.php.net/note/delete/79146/bad+code Del: spam -- https://master.php.net/note/delete/79146/spam Del: non-english -- https://master.php.net/note/delete/79146/non-english Del: in docs -- https://master.php.net/note/delete/79146/in+docs Del: other reasons-- https://master.php.net/note/delete/79146 Reject -- https://master.php.net/note/reject/79146 Search -- https://master.php.net/manage/user-notes.php
