提取 Zip 内的目录 [英] Extract Directory Inside Zip
问题描述
我正在编写一个脚本，用于将 zip 存档中的文件提取到脚本所在的目录中.
I'm writing a script to extract files from a zip archive into the directory that the script is located.
这是我的代码:
$zip = new ZipArchive;
if ($zip->open('latest.zip') === TRUE) {
$zip->extractTo('.');
$zip->close();
unlink('installer.php');
echo 'it works!';
} else {
echo 'failed';
}
这很好用，但有一个问题.拉链包含一个额外的层.(zip/directory/files) 它像这个目录/文件一样提取，而不仅仅是文件.
This works fine, but there's one problem. The zip contains an extra layer. (zip/directory/files) which extracts like this directory/files rather then just the files.
有没有办法去除这个额外的层?
Is there a way to remove this extra layer?
感谢您的帮助！

推荐答案
为了防止任何文件被覆盖，您可能希望先将 zip 文件解压缩到一个目录中.我会创建一个随机名称的目录，将 zip 解压缩到该目录中，然后检查任何子目录:
In order to prevent any files from getting overwritten, you probably want to extract the zip file into a directory first. I'd create a directory with a random name, extract the zip into that director and then check for any subdirectories:
<?php
// Generate random unzip directory to prevent overwriting
// This will generate something like "./unzip<RANDOM SEQUENCE>"
$pathname = './unzip'.time().'/';
if (mkdir($pathname) === TRUE) {
$zip = new ZipArchive;
if ($zip->open('latest.zip') === TRUE) {
$zip->extractTo($pathname);
// Get subdirectories
$directories = glob($pathname.'*', GLOB_ONLYDIR);
if ($directories !== FALSE) {
foreach($directories as $directory) {
$dir_handle = opendir($directory);
while(($filename = readdir($dir_handle)) !== FALSE) {
// Move all subdirectory contents to "./unzip<RANDOM SEQUENCE>/"
if (rename($filename, $pathname.basename($filename)) === FALSE) {
print "Error moving file ($filename) \n";
}
}
}
}
// Do whatever you like here, for example:
unlink($pathname.'installer.php');
}
// Clean up your mess by deleting "./unzip<RANDOM SEQUENCE>/"
}
我还没有测试过这段代码，所以，使用风险自负，另外，它在 Windows 系统上可能无法按预期工作.此外，请查看我使用的所有功能的文档:
I haven't tested this code, so, use at your own risk, also, it may not work as intended on Windows systems. Additionally, check out the documentation for all of the functions I used:
