note 101180 added to language.types.boolean

Dunno if someone else posted this solution already, but if not, here's a useful and function to convert strings to strict booleans. Note this one only checks for string and defaults to the PHP (boolean) cast where e.g. -1 returns true, but you easily add some elseifs for other datatypes. <?php function toStrictBoolean ($_val, $_trueValues = array('yes', 'y', 'true'), $_forceLowercase = true) { if (is_string($_val)) { return (in_array( ($_forceLowercase?strtolower($_val):$_val) , $_trueValues) ); } else { return (boolean) $_val; } } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 212.121.110.171 ---- Manual Page -- http://www.php.net/manual/en/language.types.boolean.php Edit -- https://master.php.net/note/edit/101180 Del: integrated -- https://master.php.net/note/delete/101180/integrated Del: useless -- https://master.php.net/note/delete/101180/useless Del: bad code -- https://master.php.net/note/delete/101180/bad+code Del: spam -- https://master.php.net/note/delete/101180/spam Del: non-english -- https://master.php.net/note/delete/101180/non-english Del: in docs -- https://master.php.net/note/delete/101180/in+docs Del: other reasons-- https://master.php.net/note/delete/101180 Reject -- https://master.php.net/note/reject/101180 Search -- https://master.php.net/manage/user-notes.php
