blocks|key|678151|text|请不要那样做(传递GET+var作为系统调用的一部分)。请改用ZipArchive。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|678152|因此，您的代码应该如下所示：|678153|$zipArchive+=+new+ZipArchive();

Please, don't do it like that (passing GET var to be a part of a system call). Use <a href="http://php.net/manual/en/class.ziparchive.php" rel="noreferrer">ZipArchive</a> instead.

So, your code should look like:

<pre><code>$zipArchive = new ZipArchive();
$result = $zipArchive-&gt;open($_GET["master"]);
if ($result === TRUE) {
 $zipArchive -&gt;extractTo("my_dir");
 $zipArchive -&gt;close();
 // Do something else on success
} else {
 // Do something on error
}
</code></pre>

And to answer your question, your error is 'something $var something else' should be "something $var something else" (in double quotes).

I want to unzip a file and this works fine

<pre><code>system('unzip File.zip');
</code></pre>

But I need to pass in the file name through the URL and can not get it to work, this is what I have. 

<pre><code>$master = $_GET["master"];
system('unzip $master.zip'); 
</code></pre>

What am I missing? I know it has to be something small and stupid I am overlooking.

Thank you,

Unzip a file with php

我想解压缩一个文件，这样就可以了。system('unzip File.zip');但是我需要通过URL传入文件名，并且无法使其工作，这就是我所拥有的。$master = $_GET["master"];system('unzip $master.zip'); 我遗漏了什么？我知道这一定是我忽略的一些小而愚蠢的事情。谢...
