What is the potential issue with returning an uninitialized array in PHP, even after initializing it in the code?

Returning an uninitialized array in PHP, even after initializing it in the code, can lead to unexpected behavior and potential errors when trying to access or manipulate the array later on. To solve this issue, make sure to properly initialize the array before returning it to ensure that it is properly set up and ready for use.

// Initialize the array before returning it
function initializeArray() {
    $array = [];
    
    // Add elements to the array
    $array[] = "Element 1";
    $array[] = "Element 2";
    
    return $array;
}
