面向对象的php类简单示例 [英] Object oriented php class simple example

问题描述

我是php的初学者，所以现在我尝试学习面向对象，我在偷看它，但得到了一些想法，但概念不明确.所以我来了.请任何php专家举一个简单的示例，说明如何创建类和如何调用类在其他php页面上.

例如

我想要两个类，一个是show name，第二个是enter name.第一类显示名称，该名称来自数据库，第二类显示名称在数据库中.

Index.php

<form action="checking.php" method="post">
      <input type="text" placeholder="Please enter name">
</form>

解决方案

调用php页面的方式很好.那是来自HTML.

我认为，您错了.用于从数据库获取名称的类showName和要保存在数据库中的类enterName.好吧，我建议应该是一个类中的一个函数.

<?php
class Name
{
    public $name;
    public function showName()
    {
        /**
        Put your database code here to extract from database.
        **/
        return($this->name);
    }
    public function enterName($TName)
    {
        $this->name = $TName;
        /**
        Put your database code here.
        **/
    }
}
?>

在checking.php中，您可以包括:

<?php
    include_once("name_class.php");
    $name = $_POST['name'];   //add name attribute to input tag in HTML
    $myName = new Name();
    $myName->enterName($name); //to save in database/
    $name=$myName->showName(); //to retrieve from database. 
?>

通过这种方式可以实现这一点，这只是一个概述.不仅如此.

i am beginner on php so now i try to learn object oriented i was goggling i got it some ideas but not clear concept.So i come there.Please any php guru give simple example of how to crate classes and how to call on other php page.

for example

i want two classes one is show name and second one is enter name.First class show name this name come from database and second class put name in database.

Index.php

<form action="checking.php" method="post">
      <input type="text" placeholder="Please enter name">
</form>

解决方案

The way you are calling a php page is good. That is from HTML.

What I think, you are getting this wrong. A class showName to get name from database and enterName to save in database. Well what I suggest that should be a function within one single class.

<?php
class Name
{
    public $name;
    public function showName()
    {
        /**
        Put your database code here to extract from database.
        **/
        return($this->name);
    }
    public function enterName($TName)
    {
        $this->name = $TName;
        /**
        Put your database code here.
        **/
    }
}
?>

In checking.php you can include:

<?php
    include_once("name_class.php");
    $name = $_POST['name'];   //add name attribute to input tag in HTML
    $myName = new Name();
    $myName->enterName($name); //to save in database/
    $name=$myName->showName(); //to retrieve from database. 
?>

This way you can achieve this, this is just an overview. It is much more than that.
