Xor is a bitwise operator:
0^0=0
0^1=1
1^0=1
1^1=0
If you have multiple 1 bits it is no longer a simple test.
It's not real obvious why you would do that. But the result is a match. Do you know C language? If so it is like:
Make them both 0xb1 and the test will fail.
#include <iostream.h>
class test
{
private:
int i;
public:
inline test(int m)
{
i = m;
}
inline int get_i()
{
return i;
}
};
int main()
{
test * a = new test(2); (3 Replies)

EXAMPLES
Example #1
debug_print_backtrace(3) example
<?php
// include.php file
function a() {
b();
}
function b() {
c();
}
function c(){
debug_print_backtrace();
}
a();
?>
<?php
// test.php file
// this is the file you should run
include 'include.php';
?>
The above example will output something similar to:
#0 c() called at [/tmp/include.php:10]
#1 b() called at [/tmp/include.php:6]
#2 a() called at [/tmp/include.php:17]
#3 include(/tmp/include.php) called at [/tmp/test.php:3]
