How can default parameters be implemented in PHP functions similar to C++?

In PHP, default parameters can be implemented in functions by assigning a default value to a parameter in the function definition. This allows the function to be called without providing a value for that parameter, in which case the default value will be used. This is similar to how default parameters are implemented in C++. 

function greet($name = "Guest") {
    echo "Hello, $name!";
}

greet(); // Output: Hello, Guest!
greet("John"); // Output: Hello, John!
