PHP ziparchive ReadFile的，没有这样的文件中发现错误

Question

我遇到这个错误：

[23-Jul-2013 16:26:15 America/New_York] PHP Warning: readfile(Resumes.zip): failed to open stream: No such file or directory in /home/mcaplace/public_html/download.php on line 24

这是代码：

<?php 
    /*foreach($_POST['files'] as $check) { 
     echo $check;}*/ 
    function zipFilesAndDownload($file_names,$archive_file_name,$file_path) 
    { 
     $zip = new ZipArchive(); 
     //create the file and throw the error if unsuccessful 
     if ($zip->open($archive_file_name, ZIPARCHIVE::CREATE)!==TRUE) { 
     exit("cannot open <$archive_file_name>\n"); 
     } 
     //add each files of $file_name array to archive 
     foreach($file_names as $files) 
     { 
     $zip->addFile($file_path.$files,$files); 
     /*if(file_exists($file_path.$files)) //." ".$files."<br>"; 
      echo "yes";*/ 
     } 
     $zip->close(); 
    //then send the headers to foce download the zip file 
     header("Content-type: application/zip"); 
     header("Content-Disposition: attachment; filename=$archive_file_name"); 
     header("Pragma: no-cache"); 
     header("Expires: 0"); 
     readfile($archive_file_name); 
     exit; 
    } 
    //If you are passing the file names to thae array directly use the following method 
    $file_names = $_POST['files']; 
    //if you are getting the file name from database means use the following method 
    //Include DB connection 

    $archive_file_name='Resumes.zip'; 
    $file_path=$_SERVER['DOCUMENT_ROOT']."/resumes/"; 
    zipFilesAndDownload($file_names,$archive_file_name,$file_path); 
?>

你有几件事情错 首先ZIPARCHIVE :: CREATE是不正确的，它应该是ZipArchive :: CREATE或ZipArchive :: OVERWRITE（覆盖，如果你没有删除zip文件）。

接下来你的路径是错误的。你不告诉readfile（）文件的绝对路径。因此，您需要提供绝对路径来指定zip文件的保存位置和读取位置。

此外，我觉得你的网站的根文件夹是可写的，这是不明智的。所以我把zip放到简历文件夹下面的代码中。我倾向于远离$ _SERVER ['DOCUMENT_ROOT']我的自我，并使用realpath（）函数。

最后，你必须确定什么文件夹的zip文件正在被创建成它拥有777权限。

下面是完整的代码更改

<?php 
    /*foreach($_POST['files'] as $check) { 
     echo $check;}*/ 
    function zipFilesAndDownload($file_names,$archive_file_name,$file_path) 
    { 
     $zip = new ZipArchive(); 
     //create the file and throw the error if unsuccessful 
     if ($zip->open($file_path.$archive_file_name, ZipArchive::OVERWRITE)!==TRUE) { 
      exit("cannot open <$archive_file_name>\n"); 
     } 
     //add each files of $file_name array to archive 
     foreach($file_names as $files) 
     { 
      $zip->addFile($file_path.$files,$files); 
      /*if(file_exists($file_path.$files)) //." ".$files."<br>"; 
       echo "yes";*/ 
     } 
     $zip->close(); 
    //then send the headers to foce download the zip file 
     header("Content-type: application/zip"); 
     header("Content-Disposition: attachment; filename=$archive_file_name"); 
     header("Pragma: no-cache"); 
     header("Expires: 0"); 
     readfile($file_path.$archive_file_name); 
     exit; 
    } 
    //If you are passing the file names to thae array directly use the following method 
    $file_names = array('test.txt'); 
    //if you are getting the file name from database means use the following method 
    //Include DB connection 

    $archive_file_name='Resumes.zip'; 
    $file_path=$_SERVER['DOCUMENT_ROOT']."/resumes/"; 

    zipFilesAndDownload($file_names,$archive_file_name,$file_path); 
?>
