Converting some values of a json string to double in php

Question

I have the following php code:

'fees' => number_format($_POST['fees'],2)

The sample JSON is:

{
 "fees":"74.00"
}

I need the value for fees to be a double rather than being a string.

I tried doing this:

'fees' => (double)number_format($_POST['fees'],2)

But it does not seem to work. Is there any way to make fees a double rather than it being a string?

Answer 1

If you want to convert the string value to float , you can use following code. But in Json it should be a string .

$string='123.56999';
$float  =   doubleval(number_format($string,2));
var_dump($float);
