PHP执行Linux命令行小例文件压缩,
PHP执行Linux命令行小例——文件压缩,
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:
<span>/*</span><span>拆分成3个txt文件 分别是wow_1.txt wow_2.txt 和 wow_3.txt</span><span>*/</span> <span>$zip</span>=<span>new</span><span> ZipArchive(); </span><span>$zipfile</span>='./Exl_file/wow.zip'<span>; </span><span>if</span>(<span>$zip</span>->open(<span>$zipfile</span>,ZIPARCHIVE::CREATE)===<span>TRUE</span><span>){ </span><span>$zip</span>->addFile('./Exl_file/wow_1.txt','wow_1.txt'<span>); </span><span>$zip</span>->addFile('./Exl_file/wow_2.txt','wow_2.txt'<span>); </span><span>$zip</span>->addFile('./Exl_file/wow_3.txt','wow_3.txt'<span>); </span><span>$zip</span>-><span>close(); </span><span>//</span><span>下载 输出文件后删除相关文件</span> <span> }</span><span>else</span><span>{ </span><span>echo</span> "ZIP生成失败!"<span>; }</span>
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!
<span>/*</span><span>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</span><span>*/</span> <span>$outputs</span>=<span>array</span><span>(); </span><span>/*</span><span>用php的exec执行Linux命令 括号里的字符串就是你在Linux命令窗口里敲的命令; 第二个参数是 linux执行该命令后返回的结果数组; linux执行返回的每一条结果依次存入该数组 第三个参数是结果,如果执行成功,则Linux返回结果值为0,如果执行失败,则结果值不为0 </span><span>*/</span> <span>exec</span>("zip ./Exl_file/wow.zip ./Exl_file/wow_1.txt ./Exl_file/wow_2.txt ./Exl_file/wow_3.txt",<span>$outputs</span>,<span>$rc</span><span>); </span><span>if</span>(<span>$rc</span>!=0<span>){ </span><span>foreach</span> (<span>$outputs</span> <span>as</span> <span>$ko</span>=><span>$vo</span><span>){ </span><span>echo</span> "<span>$vo</span><br/>"<span>; } }</span><span>else</span><span>{ </span><span>$zipfile</span>='./Exl_file/wow.zip'<span>; </span><span>//</span><span>文件下载 输出后删除相关文件</span> <span> } }</span>
你可以把 if($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%<span>) adding</span>: Exl_file/wow_2.txt (deflated 97%<span>) adding</span>: 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。

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 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.

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

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.
