How does Test-Driven Development (TDD) impact the development process for PHP projects, and what are the potential benefits and drawbacks of this approach?

Test-Driven Development (TDD) can impact the development process for PHP projects by requiring developers to write failing test cases before writing any production code. This approach can help ensure that the code is well-tested and meets the specified requirements. Some potential benefits of TDD include improved code quality, faster development iterations, and easier refactoring. However, drawbacks may include the initial time investment in writing tests and the need for developers to have a good understanding of testing principles. 

// Example of a simple PHP test using PHPUnit

class MyTest extends \PHPUnit\Framework\TestCase
{
    public function testAddition()
    {
        $result = 1 + 2;
        $this->assertEquals(3, $result);
    }
}
