How to Solve the

Handling "Creating Default Object from Empty Value" Error in PHP

In PHP versions >= 5.4, you may encounter the error "Creating default object from empty value" when attempting to access a property on an uninitialized object. This error signifies that the referenced variable is either null or not an object.

Recommended Solution:

To resolve this issue, declare the variable as an instance of the stdClass object in the global namespace before accessing its properties:

$res = new \stdClass();
$res->success = false;
Copy after login

Explanation:

With E_STRICT warnings enabled in PHP <= 5.3.x or error_reporting set to E_WARNING in PHP >= 5.4, PHP strictly enforces object manipulation. Attempting to access properties on a null or non-object variable will trigger an error. Declaring the variable as a stdClass object ensures that it is an object instance and can have properties assigned to it.

Alternative Approaches:

Alternatively, you can use the following approach to avoid this error:

  • Check if the variable is null or not an object before accessing its properties:
if (!isset($res) || !is_object($res)) {
    $res = new \stdClass();
}
Copy after login
  • Directly instantiate an object with the desired properties:
$res = (object) ['success' => false];
Copy after login
