PHP Warning Undefined array key logOut

This warning message indicates that the PHP code is trying to access an undefined array key "logOut". It means that the specific array key "logOut" is not defined or initialized in the code.

To fix this warning message, you need to define the array key "logOut" before trying to access it. You can define the array key by assigning a value to it, like this:

$array['logOut'] = "some value";

Alternatively, you can first check if the array key exists using the isset() function and then access it, like this:

if(isset($array['logOut'])) {
   // access the array key here
}

By doing so, you can avoid the PHP warning message and ensure that the array key is defined before accessing it.
