Are there any best practices to keep in mind when working with number formatting in PHP?

When working with number formatting in PHP, it is important to keep in mind the desired format, such as decimal places, thousands separators, and currency symbols. One best practice is to use PHP's built-in number_format() function, which allows you to easily format numbers according to your specifications. Additionally, consider using sprintf() for more advanced formatting options. 

// Example of using number_format() to format a number with 2 decimal places and a comma as a thousands separator
$number = 1234567.89;
$formatted_number = number_format($number, 2, '.', ',');
echo $formatted_number; // Output: 1,234,567.89
