How can developers with basic knowledge of unit tests improve their skills to achieve better test coverage in PHP projects?

Developers with basic knowledge of unit tests can improve their skills and achieve better test coverage in PHP projects by learning more advanced testing techniques, such as mocking dependencies and writing more comprehensive test cases. They can also utilize code coverage tools to identify areas of the code that are not being tested adequately. 

// Example code snippet demonstrating how to use PHPUnit for unit testing in PHP

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

class CalculatorTest extends PHPUnit_Framework_TestCase {
    public function testAdd() {
        $calculator = new Calculator();
        $result = $calculator->add(2, 3);
        $this->assertEquals(5, $result);
    }
}
