新手求解:Zend框架下,如何创建新Class的问题
近期在帮朋友公司改个PHP网站的后台,PHP我是半路上手,之前没弄过。
大致看了一下,网站的结构大致如下:
--------------------------------------------
/application/
./admin/controllers/
./admin/views/
/library/
./App/
./App/Db.php
./App/Model.php
./App/Db/
./App/Model/
./Zend/
/wwwroot/
...
--------------------------------------------
/library/App/Model/目录下存放的是现有的CLASS对象的PHP文件,那么我就安装相同的原理新建了一个新文件CreditYd.php,并创建一个新类:
class App_Model_CreditYd extends App_Model_Abstract
{
省略函数
}
但是在controllers中调用App_Model::factory('CreditYd');时出错。functory函数如下:
class App_Model
{
static public function factory($model)
{
$className = 'App_Model_' . $model;
$classPath = _LIB_DIR_ . '/App/Model/' . $model . '.php';
if (!file_exists($classPath)) {
throw new Exception('Class Not Fonud');
} else {
$model = new $className;
//error_log("[new className]\r\n", 3, _LIB_DIR_ . '/App/error.log');
if ($model instanceof App_Model_Abstract) {
return $model;
} else {
throw new Exception('Error');
}
}
}
}
--------------------
错误行是在 $model = new $className;,是找不到对象??
因为没有使用过Zend,也不知道如何创建对象,是不是要像C语言一样的,需要包含,需要make。
求高手解答!!!!
------解决方案--------------------
你的这种写法似乎不合他的规矩吧?不过我也没有用过这个玩意
你在 $model = new $className; 前加一句
include_once $classPath;
看看
------解决方案--------------------
呵呵 我是外行 zf 好像 有一个工具 可以方便创建 控制器 模型 试图 安装好后 直接在cmd下面 zf create xxxx 就能自己创建
------解决方案--------------------
这个类的头文件引用了没?
------解决方案--------------------
就在你写这些代码的PHP文件中的开头引用一下。include_once 'CreditYd.php';
------解决方案--------------------
一般开源的框架都是封装好的,所有的头文件及常用函数都写到一个文件中,比如include 'utils.php'在这个utils.php中引入了许多头文件,那么到你的页面中只需要引入utils.php就可以了。所以说你看不到其他文件引用你这个model的头文件。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
