How can PHP handle input of prices with both decimal points and commas and ensure accurate output?

When handling input of prices with both decimal points and commas in PHP, we can use the `str_replace()` function to remove any commas from the input string. This ensures that the input is in a format that can be accurately processed as a numerical value. We can then convert the input to a float using `floatval()` to ensure accurate calculations and output.

$input_price = "1,234.56";
$cleaned_price = floatval(str_replace(",", "", $input_price));
echo $cleaned_price; // Output: 1234.56
