pdo數據庫連接代碼

目錄

1、配置文件 config.php

2、連接數據庫文件 conn.php

3、連接使用

---

1、配置文件 config.php

class Config
{
    public static $db_name = '數據庫名稱';
    public static $db_user = '用戶名';
    public static $db_pwd = '******';
    public static $db_host = '主機IP地址';
    public static $dsn = 'mysql:dbname=數據庫名稱;host=主機IP地址';
}

2、連接數據庫文件 conn.php

include 'config.php';
class connDatabase
{
    public function connectOperator()
    {
        $dsn = Config::$dsn;
        $db_user = Config::$db_user;
        $db_pass = Config::$db_pwd;
        try {
            $pdo = new PDO($dsn, $db_user, $db_pass);
        } catch (PDOException $e) {
            echo "數據庫連接失敗" . $e->getMessage();
        }
        return $pdo;
    }
}

3、連接使用

include("conn.php");

class joinTarget{
    public function joinTargetOperator(){
        $pdoObj = new connDatabase();
        $pdo = $pdoObj->connectOperator();
        $pdo->exec("set names utf8");
        $nowTime = date("Y-m-d 00:00:00");
        $sql_account_log = "SELECT * FROM gs_account_log WHERE check_status = 2 AND create_time ='".$nowTime."'";
        $result_account_log = $pdo->query($sql_account_log);

        $result_account_log_list = $result_account_log->fetchAll();
        foreach ($result_account_log_list as $k=>$v){
            $task_id = $v['task_id'];
            $aid     = $v['aid'];

            $sql_account = "SELECT * FROM gs_account WHERE id =".$aid;
            $result = $pdo->query($sql_account);
            $account_list = $result->fetch();


            $uid = $account_list['store_target_uid'];
            $sql_account_update = "UPDATE gs_account SET uid = ".$uid." WHERE id = ".$aid ;
            $pdo->exec($sql_account_update);


            $sql_task_update = "UPDATE gs_task SET join_status = 0 WHERE id = ".$task_id ;
            $pdo->exec($sql_task_update);
        }
    }
}
$joinTargetObj = new joinTarget();
$joinTargetObj->joinTargetOperator();
