What is the typical workflow after development, including the use of integration or test servers?

After development, it is common practice to test the code on integration or test servers before deploying it to production. This helps identify any bugs or issues that may arise in a controlled environment before releasing the code to users.

// Example of using integration or test servers in PHP
// Assuming we have a function to test
function add($num1, $num2) {
    return $num1 + $num2;
}

// Testing the function on an integration server
$test_result = add(2, 3);
echo "Result of adding 2 and 3 on integration server: " . $test_result;
