note 112452 added to function.filter-var

One key thing to remember about filtering integers is that the value for the option max_range must be less than or equal to the value of PHP_INT_MAX. filter_var($someVariable, FILTER_VALIDATE_INT, array('options' => array('min_range' => 1, 'max_range' => SOME_VALUE_GREATER_THAN_PHP_INT_MAX))); This will fail even if $someVariable is a valid integer in the expected range. This can show up when you are attempting to validate a potential key for an unsigned MySQL INT type (whose maximum value is 4294967295) on a 32-bit system, where the value of PHP_INT_MAX is 2147483647. ---- Server IP: 69.147.83.199 Probable Submitter: 108.172.101.141 ---- Manual Page -- http://php.net/manual/en/function.filter-var.php Edit -- https://master.php.net/note/edit/112452 Del: integrated -- https://master.php.net/note/delete/112452/integrated Del: useless -- https://master.php.net/note/delete/112452/useless Del: bad code -- https://master.php.net/note/delete/112452/bad+code Del: spam -- https://master.php.net/note/delete/112452/spam Del: non-english -- https://master.php.net/note/delete/112452/non-english Del: in docs -- https://master.php.net/note/delete/112452/in+docs Del: other reasons-- https://master.php.net/note/delete/112452 Reject -- https://master.php.net/note/reject/112452 Search -- https://master.php.net/manage/user-notes.php
