What are the best practices for handling decimal separators in numeric values in PHP?

When handling decimal separators in numeric values in PHP, it is important to ensure consistency in the format to avoid errors in calculations or data processing. One way to handle this is by using the PHP built-in functions such as number_format() or setlocale() to format numeric values according to the desired decimal separator. 

// Example of handling decimal separators in numeric values in PHP

// Set the desired decimal separator
$decimal_separator = ',';

// Format the numeric value with the specified decimal separator
$number = 1234.56;
$formatted_number = number_format($number, 2, '.', $decimal_separator);

echo $formatted_number; // Output: 1.234,56
