mysqli连接和oop

本文介绍了mysqli连接和oop的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 如果您使用$ _SERVER重新加载页面[''PHP_SELF'']，您的程序 会在重新加载页面时丢失mysqli连接吗？这段代码 有用吗？我需要知道如何在方法之间进行连接。 我是OOP的新手？谢谢... 例子; ======================================== < ？php //网页 $ newsignon = new newuser（）; 登录（）; if（isset（$ _ POST [''submit'']））{ $ newsignon = query（" SELECT name，password FROM database"） ; } ？> <？php // class newuser class newuser { public $ name; private $ passwd; private $ mysqli; 函数__construct（）{ include（''dbconn.php''）; $ mysqli = new mysqli（$ dbnet，$ dbuser，$ dbpass，$ dbname）; if（mysqli_connect_errno（））{printf（无法连接到MySQL 服务器。错误代码：％s \\ \\ n"，mysqli_connect_error（））; 退出; } $ this-> mysqli = $ mysqli; //这是对的吗？ } //结束构造函数 函数查询（$ query）{ if（$ result） = $ this-> mysqli-> real_query（$ query））{ $ result = $ this-> mysqli-> store_result（）; if （$ this-> mysqli->错误）{echo" ERROR with mysqli storage procedure" ;;} } //结束如果 } //结束函数 函数登录（）{ echo"< form action =''"。$ _ POST [''PHP_SELF'' ]。'''method =''post''>" ;; //这会有效吗？ echo"< input type ='' text''name =''user''/>< br />< input type =''password''name =''passwd''/>" ;; echo"< input type =''submit''value =''submit''/>" ;; } //结束功能 } //结束课If you do a page reload with $_SERVER[''PHP_SELF''] will your programlose a mysqli connection upon the reload of the page? Would this codework? I need to know how to carry over a connection between methods asI am new to OOP? Thanks...Example; ========================================<?php// webpage$newsignon = new newuser();logon();if (isset($_POST[''submit''])){$newsignon = query("SELECT name, password FROMdatabase");}?><?php// class newuserclass newuser {public $name;private $passwd;private $mysqli;function __construct(){include(''dbconn.php'');$mysqli = new mysqli($dbnet, $dbuser, $dbpass, $dbname);if (mysqli_connect_errno()){ printf("Can''t connect to MySQLServer. Errorcode: %s\n", mysqli_connect_error());exit;}$this->mysqli = $mysqli; // is this right?} //end constructorfunction query($query){if ($result = $this->mysqli->real_query($query)){$result = $this->mysqli->store_result();if($this->mysqli->error) { echo "ERROR with mysqli stored procedure";}} // end if} // end functionfunction logon(){echo "<form action=''".$_POST[''PHP_SELF'']."'' method=''post'' >";// Would this work?echo "<input type=''text'' name=''user'' /><br /><inputtype=''password'' name=''passwd'' />";echo "<input type=''submit'' value=''submit'' />";} // end function} //end class推荐答案 _SERVER [''PHP_SELF''你的程序是否会在重新加载页面时丢失一个mysqli连接？这段代码 有用吗？我需要知道如何在方法之间进行连接。 我是OOP的新手？谢谢... 例子; ======================================== < ？php //网页_SERVER[''PHP_SELF''] will your programlose a mysqli connection upon the reload of the page?
