note 77595 added to ref.strings

be aware of this string behavior: $array= "foo"; echo $array["bar"]; // "f" explanation: $array is string, so $array["bar"] is evaluated as $array[0] and this is the first character of "foo". if someone passes string into your associative array (get, post or cookie), it is security risk, i.e.: isset($array["user_exists"]); // true! use array_key_exists() instead! ---- Server IP: 212.24.129.51 Probable Submitter: 81.2.196.33 ---- Manual Page -- http://www.php.net/manual/en/ref.strings.php Edit -- https://master.php.net/note/edit/77595 Del: integrated -- https://master.php.net/note/delete/77595/integrated Del: useless -- https://master.php.net/note/delete/77595/useless Del: bad code -- https://master.php.net/note/delete/77595/bad+code Del: spam -- https://master.php.net/note/delete/77595/spam Del: non-english -- https://master.php.net/note/delete/77595/non-english Del: in docs -- https://master.php.net/note/delete/77595/in+docs Del: other reasons-- https://master.php.net/note/delete/77595 Reject -- https://master.php.net/note/reject/77595 Search -- https://master.php.net/manage/user-notes.php
