How can case sensitivity affect the reading of cookies in PHP?

Case sensitivity can affect the reading of cookies in PHP because cookie names are case-sensitive. This means that if you set a cookie with a specific case, you must also read it with the exact same case. To solve this issue, you should ensure consistency in the case of cookie names when setting and reading them in your PHP code. 

// Set a cookie with a specific case
setcookie("myCookie", "exampleValue", time() + 3600, "/");

// Read the cookie with the exact same case
if(isset($_COOKIE['myCookie'])){
    $cookieValue = $_COOKIE['myCookie'];
    echo $cookieValue;
} else {
    echo "Cookie not set";
}
