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
?>
