Question

我尝试了很多代码，但没有工作。

<?php
$file = $_GET['file'];

if (isset($file))
{
   echo "Unzipping " . $file . "<br>";
   if(system('unzip '. $file.' -d dirtounzipto ' ))
   {echo 'GGWP';}else{echo 'WTF';}

   exit;
}?>

如何在服务器中解压缩。使用＆＃34; system＆＃34;或＆＃34; shell_exec＆＃34;代码。

Answer 1

$zip_filename = "test.zip";
$zip_extract_path = "/";
try{
$zip_obj = new ZipArchive;
            if (file_exists($zip_filename)) {
                $zip_stat = $zip_obj->open($zip_filename);
                if ($zip_stat === TRUE) {
                    $res = $zip_obj->extractTo($zip_extract_path);
                    if ($res === false) {

                            throw new Exception("Error in extracting file on server.");

                    }
                    $zip_obj->close();


                } else {
                    throw new Exception("Error in open file");
                }
            } else {
                throw new Exception("zip file not found for extraction");
            }
}catch (Exception $e) {

    echo $e->getMessage();
}

Answer 2

请充分利用PHP的ZipArchive library：

<?php
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
    $zip->extractTo('/my/destination/dir/');
    $zip->close();
    echo 'ok';
} else {
    echo 'failed';
}
?>

版本要求：PHP＆gt; = 5.2.0，PECL zip＆gt; = 1.1.0

更新要自动创建目标路径，您可以使用：

mkdir($path, 0755, true);

自动创建所需的文件夹。

PHP具有用于处理压缩文件的内置扩展。不需要为此使用系统调用。 ZipArchive docs是一种选择。

// assuming file.zip is in the same directory as the executing script.
$file = 'file.zip';

// get the absolute path to $file
$path = pathinfo(realpath($file), PATHINFO_DIRNAME);

//folder name as per zip file name
$foldername = basename($file, ".zip");

mkdir($foldername, 0755, true);
$path = $path . "/" . $foldername;

$zip = new ZipArchive;
$res = $zip->open($file);
if ($res === TRUE) {
  // extract it to the path we determined above
  $zip->extractTo($path);
  $zip->close();
  echo "WOOT! $file extracted to $path";
} else {
  echo "Doh! I couldn't open $file";
}
