php decompression zip file garbled problem

Official operation method:

<?php
$zip = new \ZipArchive;
$zipfile = "./test.zip";
$res = $zip->open($zipfile);
$toDir = "./test";
$s = $zip->extractTo($toDir);
print_r(scandir($toDir));

Existing problems

If the zip is compressed on the windows platform, then the above code will appear garbled when executed on the Linux server, and at the same time The decompressed files will also be missing

Solution

Problem analysis:

ZipArchive garbled characters are caused by inconsistent encoding, Windows file system is gbk encoded, while the file names in PHP ZipArchive are UTF-8 encoded. If the file name in the Zip archive contains special characters such as Chinese, it is inevitable to use PHP ZipArchive to decompress the garbled characters. The same reason applies when ZipArchive compressed files appear garbled or cannot be compressed.

Solution

Don’t use the built-in ZipArchive::extractTo() method to decompress ZipArchive documents, use PHP instead The zip packaging protocol is decompressed to solve the ZipArchive garbled code.

Solution code

<?php
$zip = new \ZipArchive;
$zipfile = "./test.zip";
$res = $zip->open($zipfile);
$toDir = "./test";
if(!file_exists($toDir)) {
   mkdir($toDir);
}
$docnum = $zip->numFiles;
for($i = 0; $i < $docnum; $i++) {
   $statInfo = $zip->statIndex($i);
   if($statInfo[&#39;crc&#39;] == 0) {
       //新建目录
       mkdir($toDir.&#39;/&#39;.substr($statInfo[&#39;name&#39;], 0,-1));
   } else {
       //拷贝文件
       copy(&#39;zip://&#39;.$zipfile.&#39;#&#39;.$statInfo[&#39;name&#39;], $toDir.&#39;/&#39;.$statInfo[&#39;name&#39;]);
   }
}
print_r(scandir($toDir));
