What are some best practices for handling numerical calculations involving commas in PHP?

When handling numerical calculations involving commas in PHP, it is important to remove the commas from the numbers before performing any calculations. This can be done using the str_replace() function to replace commas with an empty string. Once the commas are removed, the numbers can be used in calculations as needed. 

$number_with_commas = "1,000";
$number_without_commas = str_replace(",", "", $number_with_commas);

// Perform calculations with the number without commas
$result = $number_without_commas * 2;

echo $result; // Output: 2000
