What resources or documentation can help in understanding complex variable parsing in PHP?

Complex variable parsing in PHP refers to the ability to access nested arrays or objects using a single line of code. This can be achieved by using curly braces and the appropriate syntax to access the desired element within the complex variable. Understanding this concept is essential for efficiently working with multidimensional data structures in PHP. Example: 

// Define a multidimensional array
$data = [
    'user' => [
        'name' => 'John Doe',
        'email' => 'john.doe@example.com',
    ],
];

// Access nested array elements using complex variable parsing
echo "User's name: {$data['user']['name']}"; // Output: User's name: John Doe
echo "User's email: {$data['user']['email']}"; // Output: User's email: john.doe@example.com
