What are the potential drawbacks of manually testing PHP code using fake data compared to using a testing framework like PHPUnit?

Manually testing PHP code using fake data can be time-consuming and error-prone, as it requires creating and managing the fake data manually for each test case. This approach also lacks the automation and structure provided by testing frameworks like PHPUnit, which offer features such as test isolation, data providers, and assertions. Using PHPUnit can streamline the testing process, improve test coverage, and make it easier to maintain and update tests in the future. 

// Example of using PHPUnit to test a simple function

use PHPUnit\Framework\TestCase;

class MyTest extends TestCase
{
    public function testAddition()
    {
        $result = add(2, 3);
        $this->assertEquals(5, $result);
    }
}

function add($a, $b)
{
    return $a + $b;
}
