怎么解决php压缩中文乱码问题?
解决php使用ZipArchive解压时中文乱码问题(纯php,绕开ZipArchive)
解决php使用ZipArchive解压时中文乱码问题
使用php自带的ZipArchive来解压带中文文件名压缩包时会造成乱码,现象如下:
网上查阅基本上给出的答案大同小异,自己照着同样的方法试了都不能解决,下图是网上给出的方案:
经过摸索终于找到了解决方案,那就是弃用ZipArchive,选择其他的途径,经过比较我选择了“PhpZip”,优点是:纯php(不需要扩展和类),下面介绍安装方法:
composer安装:
composer require nelexa/zip
登录后复制
如果选择版本的话:composer require nelexa/zip:^3.0 (3.0版本号)
使用方法:
//解压文件
$fileAddess = "压缩包地址";
$toDir = "解压目录";
$zipFile = new \PhpZip\ZipFile();
$zipFile->openFile($fileAddess) // open archive from file
->extractTo($toDir); // extract files to the specified directory
$zipFile->close();

注释:(**如果安装好使用正常请忽略下面的注释内容**)
1.我的压缩包放在共享盘里面连接的是smb地址,可能会出现报错:"Destination is not writable directory",这个坑已经踩过:打开ZipFile.php这个文件,找到“extractTo”方法,将“is_writable”函数改掉,或者去掉,然后再转换一下编码格式!,下面有注释的是我修改的内容!
public function extractTo($destination, $entries = null)
{
if (!file_exists($destination)) {
throw new ZipException("Destination " . $destination . " not found");
}
if (!is_dir($destination)) {
throw new ZipException("Destination is not directory");
}
$is_really_writable = $this->is_really_writable($destination);
if (!$is_really_writable) {
throw new ZipException("Destination is not writable directory");
}
if (!empty($entries)) {
if (is_string($entries)) {
$entries = (array)$entries;
}
if (is_array($entries)) {
$entries = array_unique($entries);
$flipEntries = array_flip($entries);
$zipEntries = array_filter(
$this->centralDirectory->getEntries(),
function ($zipEntry) use ($flipEntries) {
return isset($flipEntries[$zipEntry->getName()]);
}
);
}
} else {
$zipEntries = $this->centralDirectory->getEntries();
}
foreach ($zipEntries as $entry) {
header("Content-type:text/html;charset=bgk");
$entry_getName = iconv('GB2312', 'UTF-8//ignore',$entry->getName());
//header("Content-type:text/html;charset=utf-8");
$file = $destination . DIRECTORY_SEPARATOR . $entry_getName;
if ($entry->isDirectory()) {
if (!is_dir($file)) {
if (!mkdir($file, 0755, true)) {
throw new ZipException("Can not create dir " . $file);
}
chmod($file, 0755);
touch($file, $entry->getTime());
}
continue;
}
$dir = dirname($file);
if (!is_dir($dir)) {
if (!mkdir($dir, 0755, true)) {
throw new ZipException("Can not create dir " . $dir);
}
chmod($dir, 0755);
touch($dir, $entry->getTime());
}
if (file_put_contents($file, $entry->getEntryContent()) === false) {
throw new ZipException('Can not extract file ' . $entry_getName);
}
touch($file, $entry->getTime());
}
return $this;
}
//王天佑加的新逻辑,判断目录是否可写
public function is_really_writable($file){
if (DIRECTORY_SEPARATOR == '/' AND @ini_get("safe_mode") == FALSE) {
return is_writable($file);
}
if (is_dir($file)) {
$file = rtrim($file, '/') . '/' . md5(mt_rand(1,100) . mt_rand(1,100));
if (($fp = @fopen($file, "w+")) === FALSE) {
return FALSE;
}
fclose($fp);
@chmod($file, 0777);
@unlink($file);
} elseif (!is_file($file) OR ($fp = @fopen($file, "r+")) === FALSE) {
fclose($fp);
return FALSE;
}
return TRUE;
}
