Simple example of using redis in PHP

<?php
// header("Content-Type: text/html;charset=utf-8");

try {
    
    $redis = new Redis();
    $redisConn = $redis->connect('127.0.0.1', 6379);
} catch (Exception $e) {
    
    $text = $e->getMessage();
    //  solve PHP The output shows a small black diamond with a question mark 
    die(iconv("GB2312", "UTF-8", $text));
}

//  Connect to database 
$host = '127.0.0.1';
$username = 'root';
$pass = '';
$dbname = 'mmw';
$conn = new mysqli($host, $username, $pass, $dbname);
if (!$conn) {
    
    die(' Database connection failed '. $conn->connect_error);
}

// rpush Add a string value from the end of the list 
// for ($i = 0; $i < 2; $i++) {
    
// $redis->rpush('test', $i);
// }

// llen Returns the length of the list 
$length = $redis->llen('test');
var_dump($length);
if ($length <= 0) {
    
    die(' No value ');
}

for ($i = 0; $i < $length; $i++) {
    
    // lpop Return and remove the first element of the list 
    $value = $redis->Lpop('test');

    try {
    
        $sql = 'insert into mmw_user (name) values (' . $value . ')';
        $result = mysqli_query($conn, $sql);
        if ($result && mysqli_affected_rows($conn) > 0) {
    
            echo ' Insert the success ';
        } else {
    
            die(' Insert the failure ');
        }
    } catch (Exception $e) {
    
        die(' Insert the failure ' . $e->getMessage());
    }

    //  Delay 1 Seconds to perform 
    sleep(1);
}
