!is_int

[salihk.]

Hello everyone,

I have no well knowledge about php coding.

I am trying to write simple php code for take some datas from mysql. My problem is  whhen i try to control my values that i take from get html with get command.

 

if(!is_int($_REQUEST["num"])

die('It is not integer');

 

When i put integer to num variable for example 2 it prints It is not integer.

Maybe i misunderstand the "!" think.

Could you help me to figure out

Thanks

Things that are in $_REQUEST will never be integers. They are always strings. is_int checks the data type, not the contents. You can use ctype_digit to solve your problem.

But in order to check the function is_int() works or not i assigned the num value to a variable

$num=$_REQUEST["num"] and add an integer

$num=$_REQUEST["num"] +1; so it is output was correct

 

than i put it to

if(is_not($num))

die('it is integer');

it prints it is integer

 

than change the code to

 

if(!is_not($num))

die('it is not integer');

and the result is the same it prints again  :-\

By the way your suggestion works properly thanks but i am confused

What's is_not()?

[Daniel0]

It's the magic function that reads your mind to make sure it's not whatever you think of

I don't know 

it should be is_int()
