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:

     

复制代码
<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>
复制代码

      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!

复制代码
<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>
复制代码


     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。
