php解压zip文件

php实现解压zip文件

function zip($filename, $path)
{
//        $filename = 'test.zip';
//        $path = './document/2016-05-11/test.zip';
    $path_all = $_SERVER['DOCUMENT_ROOT'] . sp_get_asset_upload_path(mb_substr($path, 2));//think_cmf的获取文件路劲
    $file_name_head = mb_substr($path, 0, strrpos($path, "/"));
    if (!file_exists($path_all)) {
        echo '文件不存在';
    }
    //z转码  将文件名和路径转成windows系统默认的gb2312编码，否则将会读取不到
    $filename = iconv('utf-8', 'gb2312', $filename);
    $path_all = iconv('utf-8', 'gb2312', $path_all);
    //打开压缩包
    $resource = zip_open($path_all);
    $i = 0;
    while ($dir_resource = zip_read($resource)) {
        if (zip_entry_open($resource, $dir_resource)) {
            $file_name = substr($path_all, 0, strrpos($path_all, "/")) . '/' . zip_entry_name($dir_resource);
            $dir_name = zip_entry_name($dir_resource);
            $file_path = substr($file_name, 0, strrpos($file_name, "/"));
        }
        if (!is_dir($file_path)) {
            mkdir($file_path, 0777, true);
        }
        if (!is_dir($file_name)) {
            $file_size = zip_entry_filesize($dir_resource);
            //最大读取10M，如果文件过大，跳过解压，继续下一个
            if ($file_size < (1024 * 1024 * 10)) {
                $file_content = zip_entry_read($dir_resource, $file_size);
                file_put_contents($file_name, $file_content);
            }
            //关闭当前
            zip_entry_close($dir_resource);
        }
        $dir_name = iconv('gb2312', 'utf-8', $dir_name);
        $data[$i][filename] = $file_name_head . '/' . $dir_name;
        $data[$i]['size'] = $file_size;
        $i++;
    }
    zip_close($resource);
    return $data;
}
