note 110368 added to reserved.variables.cookies

Note: When checking if a cookie exist, the in_array() does not work on the $_COOKIE array, you should isset() to check if the cookie exists. <?php /** * part 1, setting cookie */ $name = 'testCookie'; $value = 'testValue'; $expires = time() + (60 * 60 * 24 * 365); $path = '/'; setcookie($name, $value, $expires, $path); /** * part 2, retrieving cookie */ var_dump($_COOKIE); // output: array(1) { ["testCookie"] => string(9) "testValue" } var_dump(isset($_COOKIE[$name])); // output: bool(true) var_dump(in_array($name, $_COOKIE)); // does not work as aspected !!! // ouput: bool(false) echo $_COOKIE[$name]; // output: testValue ?> ---- Server IP: 69.147.83.199 Probable Submitter: 94.209.223.124 ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.cookies.php Edit -- https://master.php.net/note/edit/110368 Del: integrated -- https://master.php.net/note/delete/110368/integrated Del: useless -- https://master.php.net/note/delete/110368/useless Del: bad code -- https://master.php.net/note/delete/110368/bad+code Del: spam -- https://master.php.net/note/delete/110368/spam Del: non-english -- https://master.php.net/note/delete/110368/non-english Del: in docs -- https://master.php.net/note/delete/110368/in+docs Del: other reasons-- https://master.php.net/note/delete/110368 Reject -- https://master.php.net/note/reject/110368 Search -- https://master.php.net/manage/user-notes.php
