The instruction is to get the is_int with the following.
Example:
$num1 = 123;
$num2 = "123";
then get the is_int:
is_int ($num1); => result is true but displays in the browser 1 the instruction is to display true
is_int ($num2); => none is displayed in the browser since the answer to that condition is false, but the instruction is to display in the browser 0
how to get this?
any idea?
any help will be appreciated.. thank you!!![:)]()
