Question

这是我用来上传文件的代码然后它无法正常工作。我试图强制下载，我得到一个空白的zip文件。当我提取时，我得到一个.cpgz文件。

要创建的zip文件接缝，但上传的文件没有进入zip文件我已经更新了代码，这就是整个代码的样子

<?php
if(isset($_POST['createpdf']))
{
            $file_folder = "files/";    // folder to load files
            $zip = new ZipArchive();            // Load zip library 
            $zip_name = "upload/".time().".zip";            // Zip name
            if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){
        // Opening zip file to load files
                $error .=  "* Sorry ZIP creation failed at this time<br/>";
            }

            foreach($_FILES['file']['tmp_name'] as $k => $filesuploaded) {
                    $fname = $_FILES['name'][$k];
                    $ftmpname = $filesuploaded;

                    $zip->addFromString(basename($fname),  
  file_get_contents($ftmpname));

                    }

            $zip->close();  }
?>

以这种形式工作：

<?php
$error = '';
if(isset($_POST['createpdf'])) {
    //$file_folder = "files/";  // folder to load files
    $zip         = new ZipArchive();          // Load zip library 
    $zip_name    = "upload/" . time() . ".zip";       // Zip name

    if($zip->open($zip_name, ZipArchive::CREATE) !== TRUE) {
        //Opening zip file to load files
        $error .= "* Sorry ZIP creation failed at this time<br/>";
    }

    $files = $_FILES['file']; // current 'file' field posted from HTML page

    if(is_array($files['tmp_name'])) {
        // multi file form
        foreach($files['tmp_name'] as $k => $value) {
            if($value == '') { // not empty field
                continue;
            }
            $zip->addFromString($files['name'][$k], file_get_contents($value));
        }
    } elseif($files['tmp_name'] != '') { // not empty field
        // single file form
        $zip->addFromString($files['name'], file_get_contents($files['tmp_name']));
    }

    $zip->close();
}
?>

应该像单文件格式一样用于多文件格式。试图评论我们的有用提示。

上传多个文件并将其压缩到服务器的文件夹中
