What are some best practices for handling decimal separators in float values in PHP?

When handling decimal separators in float values in PHP, it's important to ensure consistency in the format used. This is particularly crucial when working with data from different sources or when displaying values to users. One common approach is to use the `number_format()` function in PHP, which allows you to format numbers with decimal points and thousands separators according to a specified locale. 

// Example of handling decimal separators in float values using number_format()

$number = 1234.56; // float value with decimal separator
$formatted_number = number_format($number, 2, '.', ','); // format the number with 2 decimal places, using '.' as decimal separator and ',' as thousands separator

echo $formatted_number; // Output: 1,234.56
