解决php下多人同时操作数据表

当同一时刻,多人对同一个表进行insert或者update的时候,往往会出现同一条数据出现好多次或者一些奇怪的问题,可以通过mysql的锁表机制来进行排队解决这个问题




php中插入数据之前锁表


// lock talbe write
        $sql = "LOCK TABLES alliance_perf WRITE";
        mysql_query($sql, $this->mysql->conn);
        unset($sql);
        
////////这里是数据insert操作
        
        // unlock table
        $sql = "UNLOCK TABLES";
        mysql_query($sql, $this->mysql->conn);
        unset($sql);
