At this time, your statistical system (perhaps Quantum, Baidu, etc.) will of course not be able to count. However, we can use some anti-attack software to achieve this, but the effect is sometimes not obvious. Below I provide a piece of PHP code, which can have a certain anti-CC effect.
Main function: Continuously refreshing the page more than 5 times within 3 seconds will point to the local http://127.0.0.1
Copy the code The code is as follows:
$P_S_T = $t_array[0] + $t_array [1];
$timestamp = time();
session_start();
$ll_nowtime = $timestamp;
if (session_is_registered('ll_lasttime')){
$ll_lasttime = $_SESSION['ll_lasttime'];
$ll_times = $_SESSION['ll_times'] + 1;
$_SESSION['ll_times'] = $ll_times;
}else{
$ll_lasttime = $ll_nowtime;
$ll_times = 1;
$_SESSION['ll_times'] = $ ll_times;
$_SESSION['ll_lasttime'] = $ll_lasttime;
}
if (($ll_nowtime - $ll_lasttime)<3){
if ($ll_times>=5){
header(sprintf("Location: % s",'http://127.0.0.1'));
exit;
}
}else{
$ll_times = 0;
$_SESSION['ll_lasttime'] = $ll_nowtime;
$_SESSION['ll_times'] = $ll_times;
}
The above introduces the anti-cc attack PHP anti-CC attack implementation code, including the content of anti-cc attack. I hope it will be helpful to friends who are interested in PHP tutorials.
