What are the best practices for handling numeric values and calculations in PHP scripts?

When handling numeric values and calculations in PHP scripts, it is important to ensure data validation to prevent unexpected results or errors. Always sanitize user input to avoid security vulnerabilities and use appropriate data types for numeric values. Additionally, consider using built-in PHP functions for mathematical operations to ensure accuracy and efficiency. 

// Example of handling numeric values and calculations in PHP
$number1 = 10;
$number2 = 5;

// Addition
$sum = $number1 + $number2;

// Subtraction
$diff = $number1 - $number2;

// Multiplication
$product = $number1 * $number2;

// Division
$quotient = $number1 / $number2;

echo "Sum: " . $sum . "<br>";
echo "Difference: " . $diff . "<br>";
echo "Product: " . $product . "<br>";
echo "Quotient: " . $quotient . "<br>";
