What are some best practices for handling numeric data manipulation in PHP?

When handling numeric data manipulation in PHP, it is important to ensure data integrity and accuracy. Best practices include validating input data, using appropriate data types, and handling errors gracefully. Additionally, using built-in PHP functions for mathematical operations can help prevent common pitfalls such as overflow or precision issues. 

// Example of handling numeric data manipulation in PHP
$input_number = "10"; // Input number as string
$validated_number = filter_var($input_number, FILTER_VALIDATE_INT); // Validate input as integer

if($validated_number !== false){
    $result = $validated_number * 2; // Perform arithmetic operation
    echo "Result: " . $result;
} else {
    echo "Invalid input. Please provide a valid integer.";
}
