PHP Zip Archive - open or extractTo is not working
提问by Lawrence DeSouza
I'm completely at a loss for explaining why this isn't working. HELP!
我完全无法解释为什么这不起作用。帮助！
$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);
if ($res === 'TRUE') {
$unzip_success= $zip->extractTo('/temp/', "inscriptions.txt")
$zip->close();
}
- the target dir "temp" is "0777" permissions
- the code obtained from $res is "11" and not "TRUE" as required by the documentation on PHP.net
- note: must put the full url for $archive and the first argument of extractTo
- 目标目录“temp”是“0777”权限
- 从 $res 获得的代码是“11”而不是 PHP.net 上的文档要求的“TRUE”
- 注意：必须把 $archive 的完整 url 和 extractTo 的第一个参数

if nothing works then check if your server is linux. if its linux you can run unzip command to unzip your file via php's system/exec function. i.e
如果没有任何效果，请检查您的服务器是否为 linux。如果是 linux，您可以运行 unzip 命令通过 php 的 system/exec 函数解压缩您的文件。IE
system("unzip archive.zip");
to extract specific file you can check man docs for unzip. many times due to server parameters zip library doesn't work as expected in that cases i switch back to linux commands.
要提取特定文件，您可以检查 man docs 以进行解压缩。很多时候由于服务器参数 zip 库不能按预期工作，在这种情况下我切换回 linux 命令。

ZipArcive::extractTo is case-sensitive. If file's name to be extracted do not meet zipped one exactly, the method returns false.
ZipArcive::extractTo 区分大小写。如果要提取的文件名与压缩文件名不完全一致，则该方法返回 false。

I faced the same problem, I have fixed this :)
Use $_SERVER['DOCUMENT_ROOT']for url.
My code (codeigniter):
我遇到了同样的问题，我已经解决了这个问题:) $_SERVER['DOCUMENT_ROOT']用于 url。我的代码（codeigniter）：
$this->load->library('unzip');
$file = $this->input->GET('file');
$this->unzip->extract($_SERVER['DOCUMENT_ROOT'].'/TRAS/application/uploads/' . $file,$_SERVER['DOCUMENT_ROOT'].'/TRAS/application/views/templates/' . $file);

The problem is that you are quoting TRUE, which is a keyword and should be left without single quotes. Plus, you could check if the file exists in the zip archive prior to its extraction with locateName:
问题是你在引用TRUE，这是一个关键字，应该没有单引号。另外，您可以在使用locateName提取文件之前检查该文件是否存在于 zip 存档中：
$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);
if ($res === true && $zip->locateName('inscriptions.txt') !== false) {
$unzip_success= $zip->extractTo('/tmp/', "inscriptions.txt");
$zip->close();
}

If $resis equal to 11, that means that ZipArchivecan't open the specified file.
如果$res等于11，则表示ZipArchive无法打开指定的文件。
To test this:
要测试这个：
$archive = "x.zip";
$zip = new ZipArchive();
$res = $zip->open($archive);
if($res == ZipArchive::ER_OPEN){
echo "Unable to open $archive\n";
}

Adding document root is what worked for me as well. here is my code
添加文档根目录也对我有用。这是我的代码
$zip = new ZipArchive;
if ($zip->open($_SERVER['DOCUMENT_ROOT'].'/'.$folder.$file_path) === TRUE) {
$zip->extractTo($_SERVER['DOCUMENT_ROOT'].'/$folder');
$zip->close();
echo 'ok';
}

I meet same problem, but I can open the zip file, it returns trueafter open.
我遇到了同样的问题，但是我可以打开 zip 文件，true打开后它会返回。
My issue is I got false after $zip->extractTo().
我的问题是我在$zip->extractTo().
I finally success after delete files named in CHINESE (NO-ENGILISH) in the zip file.
在 zip 文件中删除以中文（无英文）命名的文件后，我终于成功了。

I had the same problem on Windows 10. The only solution I found was just to try extractTo twice, even though the open() was successful:
我在 Windows 10 上遇到了同样的问题。我找到的唯一解决方案是尝试 extractTo 两次，即使 open() 成功了：
$zip = new ZipArchive;
if ($open === true) {
$result = $zip->extractTo($destination);
if ($result === false) {
$result = $zip->extractTo($destination);
}
$zip->close();
}
The fact that the second extractTo() works (with no intervening action) would seem to indicate that there's nothing wrong with the archive or the destination directory.
第二个extractTo() 工作（没有干预操作）的事实似乎表明存档或目标目录没有任何问题。
