What role does test-driven development (TDD) play in addressing unfinished or to-be-done tasks in PHP programming?

Test-driven development (TDD) can help address unfinished or to-be-done tasks in PHP programming by allowing developers to write tests for the desired functionality before writing the actual code. This approach ensures that the code meets the specified requirements and helps catch any potential issues early in the development process. 

// Example of using TDD to address unfinished task in PHP

// Test case
class MathTest extends PHPUnit_Framework_TestCase {
    public function testAddition() {
        $math = new Math();
        $result = $math->add(2, 3);
        $this->assertEquals(5, $result);
    }
}

// Implementation
class Math {
    public function add($a, $b) {
        return $a + $b;
    }
}
