本文实例讲述了CI框架整合widget(页面格局)的方法。分享给大家供大家参考,具体如下:
在WEB开发过程中,我们免不了要输出视图文件,而通常视图文件又一般都少不了头部、左侧栏以及底部这些公共元素。
如何让整个项目开发在涉及视图套用时引入敏捷的思维,提高效率呢?就不得不提一下widget。承然你也大可以使用HMVC模型。
这里仅介绍下widget如何结合入CI框架中:
1、在类文件MY_Controller.php中添加调用方法:
/* * 如果$name存在则调用widget类及widget方法 *@param string $name */ protected function widget ($name = '') { if (isset($name) && $name != '') { require_once BASE_WIDGET.$name.'.php'; } }
2、定义widget类文件:
<?php /*------------ widget.php 组件包含自己的控制器,视图,模型(可以共用普通model) *用来实现各页面都有的公共部分 @author crystal 20120106 --------------*/ class Widget extends MY_Controller { private function __construct() { parent::MY_Controller(); } /*** 获取当前类名*/ private static function _getClass() { return __CLASS__; } public static function left() { $class = self::_getClass(); $data['userinfo'] = MY_Controller::_getUserCookieInfo(); $this->load->view('com/left.php',$data); } } ?>
3、在视图文件中调用(在相应的控制器中应该先调用父类控制中的widget方法):
<!--left sider --> <div> <?php Widget::left();?> </div> ... <!--/left sider -->

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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.
