What are some best practices for handling numeric values in PHP arrays?

When working with numeric values in PHP arrays, it is important to ensure that the values are properly formatted and handled to avoid unexpected results or errors. One best practice is to use appropriate data types for numeric values, such as integers or floats, to maintain accuracy and prevent data loss. Additionally, sanitizing input and validating numeric values before storing them in an array can help prevent security vulnerabilities and ensure data integrity. 

// Example of handling numeric values in PHP arrays

// Define an array with numeric values
$numbers = [1, 2, 3, 4, 5];

// Loop through the array and perform operations on numeric values
foreach ($numbers as $number) {
    // Ensure the value is a valid integer
    if (is_numeric($number)) {
        // Perform calculations or operations on the numeric value
        $result = $number * 2;
        echo $result . "\n";
    } else {
        // Handle non-numeric values or errors
        echo "Invalid numeric value: " . $number . "\n";
    }
}
