How to remove a cookie with PHP?
To remove a cookie with PHP, we can use the unset and setcookie functions.
For instance, we write
if (isset($_COOKIE["remember_user"])) {
unset($_COOKIE["remember_user"]);
setcookie("remember_user", null, -1, "/");
return true;
} else {
return false;
}
in a function.
We check if the cookie with name 'remember_user' is set with isset.
If it is, then we call unset to remove it from the $_COOKIE array.
And we call setcookie to send the 'remember_user' cookie with -1 to make it expire.
Conclusion
To remove a cookie with PHP, we can use the unset and setcookie functions.
