What are the potential pitfalls of not testing PHP code before implementing it in a project?

Not testing PHP code before implementing it in a project can lead to various issues such as bugs, errors, and unexpected behavior in the application. This can result in a poor user experience, security vulnerabilities, and potential downtime. To avoid these pitfalls, it is crucial to thoroughly test PHP code using unit tests, integration tests, and other testing methodologies before integrating it into a project. 

// Example of a simple unit test using PHPUnit
class MyTest extends \PHPUnit\Framework\TestCase {
    public function testAddition() {
        $result = 1 + 1;
        $this->assertEquals(2, $result);
    }
}
