Yii中引入php文件及插件
作者:zccst
一、设置环境变量(在PHP)
echo get_include_path(); //获取当前所有环境变量。即该项目中那些代码已被引用。
set_include_path('.'. PATH_SEPARATOR . Yii::app()->basePath.'/lib/PHPExcel' . PATH_SEPARATOR . get_include_path()); //新增一个环境变量,写在最前面。
echo get_include_path();
通过两次差别,可以看出,使用set_include_path()函数,设置新的环境变量成功。
二、在YII中引用
1,Yii::import("application.lib.PHPExcel.*");
解释:
application相当于protected文件夹。
2,在yii的../config/main.php中,引入基路径
return array( 'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..', ...... // autoloading model and component classes 'import'=>array( 'application.models.*', 'application.components.*', 'application.helpers.*', // helper methods 'ext.mail.Message', 'application.lib.*', ), )
在代码中可以使用下面方式引用
Yii::app()->basePath
3,在controller使用
//引入PHPExcel相关文件 require_once 'PHPExcel.php'; require_once 'PHPExcel/IOFactory.php'; require_once 'PHPExcel/Writer/Excel2007.php'; require_once 'PHPExcel/Writer/Excel5.php';
三、在Yii中引用插件
注:插件和扩展不一样
1,源码放在project/ckeditor/*
2,在代码create,update中引用
<?php include_once "/ckeditor/ckeditor.php"; // Create a class instance. $CKEditor = new CKEditor(); // Path to the CKEditor directory. $CKEditor->basePath = Yii::app()->baseUrl.'/ckeditor/'; // Replace a textarea element with an id (or name) of "textarea_id". $CKEditor->replace("News_content"); ?>
引入插件方法二:
第一,比如说,我们要使用 Zend framework的东西。我们把zend framework解压到 prtected/vendors里面,现在的文件夹为 protected/vendors/Zend/Search/Lucene.php
第二,在controller文件的头部,插入下面代码。
Yii::import(’application.vendors.*’);
require once(’Zend/Search/Lucene.php’);
上面代码包含了Lucene.php这个类文件。因为我们用到的是相对路径,所以我们需要改变PHP加载文件的路径,Yii::import 一定要在require_once 之前。
第三,一旦我们设置好了,我们就可以在controller里面使用了。比如说
$lucene=new Zend Search Lucene($pathOfIndex);
$hits=$lucene->find(strtolower($keyword));
四、在一个页面中引入任意其他文件
比如,想在../controllers/OutsourceController.php直接使用../components/RMSClient.php,可用如下方法
require_once(dirname(__FILE__)."/../components/RMSClient.php"); //注意以下方式引入,提升找不到 require_once(Yii::app()->baseUrl . "/protected/components/RMSClient.php"); //原因:include、require包含的是服务器上的文件路劲,和url没有直接关系。 //如果想用yii::app()方式,可以使用../config/main.php中的Yii::app()->basePath.

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.
