Question

大家好，我已经过了几天没有任何回应我试图解决问题，我在php上并不擅长，但我正在尽我所能。

我想自动下载，而不是在服务器上保存一个名为Bigzip的拉链

在这个Bigzip中： - 另一个叫做Smallzip的拉链

但是打开下载的zip时出现错误，已损坏

<?php

//Big and Small Archives names
$BzipN='Bigzip.zip';
$SzipN='Smallzip.zip';

//Big and Small Archives
$Bzip = new ZipArchive();
$Szip = new ZipArchive();




//File path
$file_path=$_SERVER['DOCUMENT_ROOT'].'/PF/';




zipFilesAndDownload($BzipN,$SzipN,$Bzip,$Szip,$file_path);

function zipFilesAndDownload($BzipN,$SzipN,$Bzip,$Szip,$file_path)
{


//create the file and throw the error if unsuccessful
if ($Bzip->open($BzipN, ZIPARCHIVE::CREATE )!==TRUE) {
exit("cannot open <$BzipN>\n");
}
if ($Szip->open($SzipN, ZIPARCHIVE::CREATE )!==TRUE) {
exit("cannot open <$SzipN>\n");
}



//Add Smallzip to BigZip
$Bzip->addFile($file_path.$SzipN,$Szip);


$Szip->close();
$Bzip->close();
//then send the headers to foce download the Big zip file
header("Content-type: application/zip"); 
header("Content-Disposition: attachment; filename=$BzipN");
header("Content-length: " . filesize($BzipN));
header("Pragma: no-cache"); 
header("Expires: 0"); 
readfile("$BzipN");
exit;
}
?>

如果您有任何其他选择，想法和建议，我会很乐意接受它。

谢谢

Answer 1

问题编号1：
您无法在空的zip存档中创建空的zip存档。这将导致文件损坏。

第2期：
当你还没有关闭第一个zip存档时，不要尝试将zip存档添加到另一个zip存档。

第3期：
$Bzip->addFile($file_path.$SzipN,$Szip);那你为什么要把对象设置为你的文件名呢？ =＆GT; $Szip = new ZipArchive();

<强>解决方案：

<?php

//Big and Small Archives names
$BzipN='Bigzip.zip';
$SzipN='Smallzip.zip';

//Big and Small Archives
$Bzip = new ZipArchive();
$Szip = new ZipArchive();

//File path
$file_path=$_SERVER['DOCUMENT_ROOT'].'/PF/';


function zipFilesAndDownload($BzipN,$SzipN,$Bzip,$Szip,$file_path){
    // Create the file Smallzip.zip and throw the error if unsuccessful
    if ($Szip->open($SzipN, ZIPARCHIVE::CREATE )!==TRUE) {
        exit("cannot open <$SzipN>\n");
    }

    // Add a txt file to Smallzip so it isn't empty
    $Szip->addFromString("testfilephp.txt", "#1 This is a test string added as testfilephp.txt.\n");

    // Close Smallzip.zip as we're done with it
    $Szip->close();

    // Create the file Bigzip.zip and throw the error if unsuccessful
    if ($Bzip->open($BzipN, ZIPARCHIVE::CREATE )!==TRUE) {
        exit("cannot open <$BzipN>\n");
    }

    // Add Smallzip.zip to Bigzip.zip with a valid name
    $Bzip->addFile($file_path.$SzipN,$SzipN);

    // Close Bigzip.zip as we're done with it
    $Bzip->close();

    //then send the headers to foce download the Big zip file
    header("Content-type: application/zip"); 
    header("Content-Disposition: attachment; filename=$BzipN");
    header("Content-length: " . filesize($BzipN));
    header("Pragma: no-cache"); 
    header("Expires: 0"); 
    readfile("$BzipN");

    // Delete the files from the server, even if the user cancels the download
    ignore_user_abort(true);
    unlink($file_path.$SzipN);
    unlink($file_path.$SzipN);
    exit;
}

zipFilesAndDownload($BzipN,$SzipN,$Bzip,$Szip,$file_path);

?>

如果你不想在服务器上保存文件只是echo创建的文件。 index.php

<form action="test.php" method="post">
To file: <input type="text" name="tofile" />
<input type="submit" />
</form>

test.php的

<?php
$filename = 'test-download.zip';
$htmlcode1 = "<HTML> \n <BODY>";
$htmlcode2 = "</BODY> \n <HTML>";
$somecontent = $htmlcode1.$_POST["tofile"].$htmlcode2;
!$handle = fopen($filename, 'w');
fwrite($handle, $somecontent);
fclose($handle);


header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Length: ". filesize("$filename").";");
header("Content-Disposition: attachment; filename=$filename");
header("Content-Type: application/octet-stream; "); 
header("Content-Transfer-Encoding: binary");

readfile($filename);

?>
