如何解压缩上传的zip文件？ [英] how to unzip uploaded zip file?

问题描述

我正在尝试使用带有以下代码的codeigniter框架上传压缩文件

I am trying to upload a zipped file using codeigniter framework with following code

function do_upload()
{
    $name=time();
    $config['upload_path'] = './uploadedModules/';
    $config['allowed_types'] = 'zip|rar';
    $this->load->library('upload', $config);

    if ( ! $this->upload->do_upload())
    {
        $error = array('error' => $this->upload->display_errors());

        $this->load->view('upload_view', $error);
    }
    else
    {
        $data = array('upload_data' => $this->upload->data());

        $this->load->library('unzip');

    // Optional: Only take out these files, anything else is ignored
    $this->unzip->allow(array('css', 'js', 'png', 'gif', 'jpeg', 'jpg', 'tpl', 'html', 'swf'));

     $this->unzip->extract('./uploadedModules/'.$data['upload_data']['file_name'], './application/modules/'); 



        $pieces = explode(".", $data['upload_data']['file_name']);
        $title=$pieces[0];
        $status=1;
        $core=0;
        $this->addons_model->insertNewModule($title,$status,$core);

    }
}

但是主要的问题是提取函数被调用，它提取压缩文件，但结果是空文件夹。有什么方法可以解决这个问题？

But the main problem is that when extract function is called, it extract the zip but the result is empty folder. Is there any way to overcome this problem?

推荐答案

$zip = new ZipArchive;

     $res = $zip->open($fileName);

    if($res==TRUE)
        {  
            $zip->extractTo($path.$fileName);

            echo "<pre>";
            print_r($zip);//to get the file type


            $zip->close();
