我的代码能够打开我已经上传并移动到文件夹中的zip文件的问题,zip文件上传很好,你可以在任何Zip程序中打开它然而,当我尝试用ZipArchive打开它时提取错误的数据。
$path = "../"; // Upload directory
$count = 0;
foreach ($_FILES['files']['name'] as $f => $name) {
if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path . $name))
$count++; // Number of successfully uploaded file
}
$kioskFile = $_FILES['files']['name'][0];
$kioskFile = explode(".", $kioskFile);
$kioskFile = $kioskFile[0];
$zipFile = "../" . $kioskFile . ".zip";
$zip = new ZipArchive;
$res = $zip->open($zipFile);
if ($res === true) {
$zip->extractTo("./");
$zip->close();
} else {
echo "Error Cannot Open Zip File - Error Code: ";
}
当我运行代码时,它会显示错误代码19
ZIPARCHIVE :: ER_NOZIP - 19
这是我得到的错误,但文件存在,如果我使用zip_open,它返回它可以打开zip文件。
任何帮助都会非常棒
EDIT1 如果我上传我手动创建的zip文件(使用zip程序),那么上传工作正常。但是,如果我使用ZipArchive创建的zip文件,那么它会立即出错并出现错误19。
EDIT2 我现在添加了一个检查,以确保该文件存在于正确的目录中,并且还放置了该位置的打印,两者都匹配,但仍然是相同的问题。错误19
$path = "../"; // Upload directory
$count = 0;
foreach ($_FILES['files']['name'] as $f => $name) {
if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path . $name))
$count++; // Number of successfully uploaded file
}
$kioskFile = $_FILES['files']['name'][0];
$kioskFile = explode(".", $kioskFile);
$kioskFile = $kioskFile[0];
$realpath = realpath("../");
$zipFile = $realpath . "\\" . $kioskFile . ".zip";
if (file_exists($zipFile)) {
$extract = zip_extract($zipFile, "../");
if ($extract === TRUE) {
} else {
echo "The file " . $zipFile . " cannot be opened";
}
} else {
echo "The file " . $zipFile . " does not exist";
die();
}
UPDATE1 所以我想我已经把它缩小到这个代码,或者我用来从系统下载.zip文件的下载脚本,如果我在系统上保留zip并使用完全相同的代码,它工作正常
这是我的下载代码,也许我错过了导致此问题的内容。
$fileID = $_GET['id'];
$backupLoc = "backups/";
$sql = "SELECT * FROM backups WHERE id = '" . addslashes($fileID) . "' LIMIT 1";
$res = mysql_query($sql);
$row = mysql_fetch_array($res);
$backupFile = $row['backupFile'];
$zipFile = $backupLoc . "/" . $backupFile . ".zip";
$zipSize = filesize($zipFile);
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="' . basename($zipFile). '"');
ob_end_flush();
readfile($zipFile);
exit;
die();

使用文本或十六进制编辑器打开存档,并确保您拥有' PK'文件开头的签名。 如果您在该签名之前有任何HTML,则表明您的缓冲区未被清除或者在它们不应该被刷新时被刷新,这意味着PHP ZipArchive将假定存档无效。

导致问题的是download.php文件,这是解决方案。这是做一个OB CLEAN而不是Flush
///echo "<div style='padding: 50px;'>Please Wait .....</div>";
$fileID = $_GET['id'];
$backupLoc = "backups/";
$sql = "SELECT * FROM backups WHERE id = '" . addslashes($fileID) . "' LIMIT 1";
$res = mysql_query($sql);
$row = mysql_fetch_array($res);
$backupFile = $row['backupFile'];
$zipFile = $backupLoc . "/" . $backupFile . ".zip";
$zipSize = filesize($zipFile);
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="' . basename($zipFile). '"');
//ob_end_flush();
ob_end_clean();
readfile($zipFile);
exit;
die();
