note 86809 added to language.types.boolean

Beware of certain control behavior with boolean and non boolean values : <?php // Consider that the 0 could by any parameters including itself var_dump(0 == 1); // false var_dump(0 == (bool)'all'); // false var_dump(0 == 'all'); // TRUE, take care var_dump(0 === 'all'); // false // To avoid this behavior, you need to cast your parameter as string like that : var_dump((string)0 == 'all'); // false ?> ---- Server IP: 89.31.146.176 Probable Submitter: 91.163.188.142 ---- Manual Page -- http://www.php.net/manual/en/language.types.boolean.php Edit -- https://master.php.net/note/edit/86809 Del: integrated -- https://master.php.net/note/delete/86809/integrated Del: useless -- https://master.php.net/note/delete/86809/useless Del: bad code -- https://master.php.net/note/delete/86809/bad+code Del: spam -- https://master.php.net/note/delete/86809/spam Del: non-english -- https://master.php.net/note/delete/86809/non-english Del: in docs -- https://master.php.net/note/delete/86809/in+docs Del: other reasons-- https://master.php.net/note/delete/86809 Reject -- https://master.php.net/note/reject/86809 Search -- https://master.php.net/manage/user-notes.php
