[英]PHP downloading files has been corrupted(While downloading from ftp server)
我在從特定文件夾下載文件(php)時遇到問題。
當我下載並打開文件時,它說您的文件已損壞。
當我檢查上傳文件和下載文件的大小時,它是相同的,但對於 zip 文件大小,它不同。
沒有文件正在打開。
誰能說我錯在哪里???
if (isset($_GET['file']) && basename($_GET['file']) == $_GET['file']) {
$filename = $_GET['file'];
}
else
{
$filename = NULL;
}
$err = 'Sorry, the file you are requesting is unavailable.';
if (!$filename) {
// if variable $filename is NULL or false display the message
echo $err;
}
else
{
// define the path to your download folder plus assign the file name
$path = '/public_html/wp-content/uploads/'.$filename;
// check that file exists and is readable
if (file_exists($path) && is_readable($path)) {
// get the file size and send the http headers
$size = filesize($path);
header ("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Content-Type: application/octet-stream');
header('Content-Length: '.$size);
header('Content-Disposition: attachment;filename="'.basename($filename).'"');
header('Content-Transfer-Encoding: binary');
// open the file in binary read-only mode
// display the error messages if the file can´t be opened
$file = @ fopen($path, 'rb');
if ($file) {
// stream the file and exit the script when complete
fpassthru($file);
exit;
} else {
echo $err;
}
} else {
echo $err;
}
exit;
}
插入表:
echo "<tr><td><a href='?file=" . $row["FileupName"]. "'>".$row["FileupName"]."</td></tr>";
我很高興文件正在下載,但沒有打開。
.txt 文件正在打開。
也檢查過標題。
我試過把:
ob_clean();
flush();
readfile($file);
if (file_exists($path)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . basename($path));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($path));
ob_clean();
flush();
readfile($path);
exit;
}
