Hi guys,
The variable '$pixels' in the code below may be an integer type or an
integer represented as a string type. I need to check if the value is
indeed one of these. Is the following code the simplest I can get?
if (!is_int($pixels) && !ctype_digit($pixels))
{
// some code
}
How about is_numeric() ?
$pixels_numeric = 25;
$pixels = '25';
var_dump($pixels);
var_dump($pixels_numeric);
var_dump(is_numeric($pixels));
var_dump(is_numeric($pixels_numeric));
var_dump(!ctype_digit($pixels));
var_dump(!ctype_digit($pixels_numeric));
var_dump(!is_int($pixels) && !ctype_digit($pixels));
var_dump(!is_int($pixels_numeric) && !ctype_digit($pixels_numeric));
