What are the best practices for using comparison operators in PHP to achieve desired outcomes?

When using comparison operators in PHP, it is important to understand the different operators available and their behaviors. To achieve desired outcomes, make sure to use the correct operator for the comparison you want to make (e.g., == for equality, === for identical, != for not equal, etc.). Additionally, be mindful of type coercion when comparing values of different types. 

// Example: Using the identical operator to compare both value and type
$num1 = 5;
$num2 = "5";

if ($num1 === $num2) {
    echo "The values are identical.";
} else {
    echo "The values are not identical.";
}
