How to mock a function with multiple return value types in PHP?

Mocking functions with multiple return value types in PHP: Use arrays. 1. Define a function that returns an array, with each value corresponding to a key-value pair. 2. Use the array access notation ('[]') to obtain a single return value.

Mocking functions with multiple return value types in PHP

Introduction

In PHP, functions usually return a single value. However, sometimes you need functions with multiple return values. One way to simulate multiple return value types is to use an array.

Solution: Use an array

Suppose you have a function called get_data() that needs to return two values: a name and an age. You can simulate this behavior using the following code:

function get_data() {
  return array('name' => 'John Doe', 'age' => 30);
}

Practical case

The following code is a practical example demonstrating how to use the get_data() function :

$data = get_data();

echo "Name: " . $data['name'] . "\n";
echo "Age: " . $data['age'];

Output:

Name: John Doe
Age: 30

Conclusion

Using arrays to simulate functions with multiple return value types is a simple and flexible way, Can be implemented in PHP. This allows you to conveniently return multiple values ​​and organize your data using key-value pairs.
