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

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.
