How can PHP developers ensure that variables are correctly initialized to prevent errors in calculations?

To prevent errors in calculations due to uninitialized variables, PHP developers should always initialize variables with default values before performing any calculations. This ensures that the variables have a defined value, preventing unexpected results or errors in calculations. 

// Initialize variables with default values
$number1 = 0;
$number2 = 0;

// Perform calculations using the initialized variables
$result = $number1 + $number2;

// Output the result
echo "The result of the calculation is: " . $result;
