Question

I need to filter the value like this 100.50 using filter_var in PHP.
Now I am using like this
filter_var($_POST['amount'],FILTER_SANITIZE_NUMBER_INT) : '';
And it gives me the result is 10050 .
How can I solve this problem.
Thanks in advance.

Answer 1

An integer does not have decimal fractions, so the validation must fail (although I find the sanitation result of 100.50 turning into 10050 pretty bizarre on PHP’s end. WTF?).

You would need to use a different filter, e.g. FILTER_VALIDATE_FLOAT.
