From: au <email protected>
Operating system: Linux 2.0.35
PHP version: 3.0.1
PHP Bug Type: Misbehaving function
Bug description:
The functions is_int() and is_long() don't return true if the given argument is a variable:
echo is_int(12345);
--> 1
echo is_int("12345");
--> (nothing returned!!)
$abc = "12345";
echo is_int($abc);
--> (nothing returned!!)
echo is_int("abcdef");
--> (nothing returned!!)
$abc = "abcdef";
echo is_int($abc);
--> (nothing returned!!)
Is this behaviour a bug or a feature?
