前几天工作中,需要将3个txt文件,打包成*.zip down到本地……
一开始,我和普通青年一样,想到用PHP内置的 ZipArchive,代码看起来应该是这样的:
/*拆分成3个txt文件 分别是wow_1.txt wow_2.txt 和 wow_3.txt*/
$zip=new ZipArchive();
$zipfile='./Exl_file/wow.zip';
if($zip->open($zipfile,ZIPARCHIVE::CREATE)===TRUE){
$zip->addFile('./Exl_file/wow_1.txt','wow_1.txt');
$zip->addFile('./Exl_file/wow_2.txt','wow_2.txt');
$zip->addFile('./Exl_file/wow_3.txt','wow_3.txt');
$zip->close();
//下载输出文件后删除相关文件
}else{
echo "ZIP生成失败!";
}
可是纠结的是正式环境上没安装zip扩展,ZipArchive直接没法用,代码绝对比在上面装个扩展要来的快——用PHP调用Linux的命令行 ,执行压缩命令,OK,马上行动!
/*拆分成3个txt文件 分别是wow_1.txt wow_2.txt 和 wow_3.txt全部放到 Exl_file 目录下*/
$outputs=array();
/*用php的exec执行Linux命令 括号里的字符串就是你在Linux命令窗口里敲的命令;
第二个参数是linux执行该命令后返回的结果数组;
linux执行返回的每一条结果依次存入该数组
第三个参数是结果,如果执行成功,则Linux返回结果值为0,如果执行失败,则结果值不为0
*/
exec("zip ./Exl_file/wow.zip ./Exl_file/wow_1.txt ./Exl_file/wow_2.txt ./Exl_file/wow_3.txt",$outputs,$rc);
if($rc!=0){
foreach ($outputs as $ko=>$vo){
echo "$vo
";
}
}else{
$zipfile='./Exl_file/wow.zip';
//文件下载输出后删除相关文件
}
}
你可以把if($rc!=0)改成if(1==1)查看Linux执行命令返回的结果行,如下图:
adding: Exl_file/wow_1.txt (deflated 96%)
adding: Exl_file/wow_2.txt (deflated 97%)
adding: Exl_file/wow_3.txt (deflated 97%)
可以看到执行返回的信息全部输入到了 $outputs 数组中,*.zip文件生成成功。

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.
