使用COM,可以在PHP中控制Excel。下面通过一个简单的示例来演示PHP如何与Excel相交互(示例中有详细的注释):

 1  php
 2       // 指定页面编码,防止出现中文乱码的情形
 3       header ( ' Content-type: text/html; charset=gb2312 ' );
 4   
 5       // 启动Excel
 6       $ms_excel = new  COM( " excel.application " ) or  die ( " 不能打开Excel应用程序 " );
 7   
 8       // 在网页中显示当前的Excel版本
 9       echo   " Excel版本:{ $ms_excel ->Version}\n " ;
10   
11       // 新建一个工作簿
12       $ms_excel -> Application -> Workbooks -> Add() or  die ( " 不能添加新工作簿 " );
13   
14       // 在工作簿的工作表Sheet1中单元格A1中输入文本
15       $ms_excel -> Worksheets( " Sheet1 " ) -> Range ( " A1 " ) -> Value = " 测试 " ;
16   
17       // 保存工作簿,如果没有指定路径,则默认保存在我的文档中
18       $ms_excel -> Workbooks( 1 ) -> SaveAs( " php_excel_test.xls " );
19   
20       // 关闭工作簿
21       $ms_excel -> Quit();
22   
23       // 清空对象
24       $ms_excel = null ;
25  ?>

在htdocs文件夹中将该文件保存为“excelsample.php”。打开浏览器,在地址栏中输入:

http://localhost/excelsample.php

此时,将会在页面中显示当前的Excel版本,同时创建名为php_excel_test.xls的工作簿并在工作表Sheet1单元格A1中输入“测试”。
打开工作簿php_excel_test.xls,在单元格A1中将会看到已经输入了“测试”。
注:为防止出现乱码,在代码开始设置了编码格式,同时在保存文件时选择保存为gb2312格式。

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
