內拉鏈（PHP）
[英]Zip inside zip (php)
問題描述
大家好，我已經嘗試了幾天而沒有任何回應，我對php並不滿意，但是我正在努力。
我想自動下載，而不在服務器上保存名為Bigzip的zip文件
在此Bigzip內部：-另一個名為Smallzip的拉鏈
但是打開下載的zip時出現錯誤，它已損壞
<?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;
}
?>
如果您有其他選擇，想法和建議，我將很樂意接受。
謝謝

問題編號1：
您無法在空的zip檔案中創建空的zip檔案。 這將導致文件損壞。
問題編號2：
在您尚未關閉第一個zip存檔的情況下，請勿嘗試將其添加到另一個zip存檔。
問題編號3：
$Bzip->addFile($file_path.$SzipN,$Szip); 那么，為什么要嘗試將對象設置為文件名呢？ => $Szip = new ZipArchive();
解：
<?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);
?>

如果您不想在服務器上保存文件，只需回顯創建的文件。 的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); ?>
