Design and Implementation of PHP Counter Page 1/2_PHP Tutorial
本程序有4个计数器。
index.php是一个普通的计数器可以看出总次数和哪个人来这个站点的次数,点几次加几次,不防水。
index1.php也是一个防水的计数器可以看出次数和哪个人来这个站点的次数,点几次加几次,防水,5秒加一次。
index2.php是一个防水的计数器可以看出总次数和哪个人来这个站点的次数,点几次加几次,防水,2秒加一次。
indexa.php是一个普通和防水和图形的计数器3合一的。可以看出总次数和哪个人来这个站点的次数,防水,有图形。
关键语句:
防水的:$sql = "SELECT COUNT(*) FROM `counter_1` WHERE user='$user' AND TIME_TO_SEC(NOW()-`time`) < 5 AND ip='$REMOTE_ADDR'";
图形计数器: for ( $i=0; $i< strlen($row[0]);$i++)
{
$digit= substr($row[0],$i,1);
$pic.="";
}

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
