在PHP中操作Excel
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。

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security.
