How can PHP interpret commas as periods for decimal numbers to avoid manual changes?

To interpret commas as periods for decimal numbers in PHP, you can use the `str_replace()` function to replace commas with periods before converting the string to a float. This will allow PHP to correctly interpret the decimal number format regardless of whether commas or periods are used. 

// Example input with commas as decimal separators
$number_with_commas = "1,234.56";

// Replace commas with periods and convert to float
$number = (float) str_replace(',', '.', $number_with_commas);

// Output the correctly interpreted decimal number
echo $number;
