Form validation with Greater Than won't work with international currencies (comma separated decimal numbers)

You'll want to sanitize the numbers further, because given your example, a number with thousands would then contain more than one decimal point, providing incorrect results when comparing. For example:

Code:

$num1 = '102,33';
$num2 = '1.044,98';

$num1 = str_replace(',', '.', $num1); // 102.33
$num2 = str_replace(',', '.', $num2); // 1.044.98

var_dump($num1 > $num2); // bool(true)
