What are the implications of treating decimal numbers with commas as strings in PHP, and how can this be avoided?

Treating decimal numbers with commas as strings in PHP can lead to unexpected behavior when performing mathematical operations. To avoid this issue, you can use the `str_replace()` function to remove the commas from the string before converting it to a float for calculations. 

// Example code snippet to avoid treating decimal numbers with commas as strings
$decimalNumber = "1,234.56";
$decimalNumber = str_replace(',', '', $decimalNumber);
$decimalNumber = (float) $decimalNumber;

// Now $decimalNumber can be safely used in mathematical operations
