What are some best practices for handling numeric values in PHP to avoid formatting errors?

When handling numeric values in PHP, it is important to ensure that proper formatting is maintained to avoid errors. One common issue is dealing with decimal points and commas in numeric values, especially when working with international data. To avoid formatting errors, it is recommended to use PHP's number_format() function to format numeric values consistently.

// Example of handling numeric values using number_format() function
$number = 1234567.89;
$formatted_number = number_format($number, 2, '.', ',');
echo $formatted_number; // Output: 1,234,567.89
