This article describes how to add counters on your own image website. Assume that you have multiple image sites as an example. first, insert several new data num and visited into the data table, which will be used on your image site, change count1.php in the previous article. create a folder named count and put the count2.php, count3.php, and so on ......, For example, in the count2 source code, you can use cou to describe how to add counters on your own image site.

Use the counter code directly in the PHP file:
$countfile = "Num.txt";
The definition counter writes the file to the current directory under Num.txt, and then we should test whether the file can be opened
if ($fp = fopen ($countfile, "r+") = = False) {//Open file in read/write mode, exit if not open
printf ("Open file%s failed!", $countfile);
Exit
}
Else
{
If the file can open normally, read the data in th

First, the principle:CTR Mode is a stream cipher that generates a key stream by encrypting successive accumulated counters, and in CTR mode, each packet corresponds to a successive cumulative counter, and the key stream is generated by encrypting the counter. The final cipher packet is obtained by XOR the bit sequence encrypted by the counter and the plaintext pa
