我正在使用phpdocx来创建word文档。当我在服务器上查看它时,它是一个有效的word文档。但是,当我尝试下载它时,它说该文件无法打开,因为该文件存在问题。 Word能够恢复文档,但客户端会抱怨无效的Word文档。这是我用来下载文件的代码:
function readfile_chunked_remote($filename, $seek = 0, $retbytes = true, $timeout = 3) {
set_time_limit(0);
$defaultchunksize = 1024*1024;
$chunksize = $defaultchunksize;
$buffer = '';
$cnt = 0;
$remotereadfile = false;
if (preg_match('/[a-zA-Z]+:\/\//', $filename))
$remotereadfile = true;
$handle = @fopen($filename, 'rb');
if ($handle === false) {
return false;
}
stream_set_timeout($handle, $timeout);
if ($seek != 0 && !$remotereadfile)
fseek($handle, $seek);
while (!feof($handle)) {
if ($remotereadfile && $seek != 0 && $cnt+$chunksize > $seek)
$chunksize = $seek-$cnt;
else
$chunksize = $defaultchunksize;
$buffer = @fread($handle, $chunksize);
if ($retbytes || ($remotereadfile && $seek != 0)) {
$cnt += strlen($buffer);
}
if (!$remotereadfile || ($remotereadfile && $cnt > $seek))
echo $buffer;
ob_flush();
flush();
}
$info = stream_get_meta_data($handle);
$status = fclose($handle);
if ($info['timed_out'])
return false;
if ($retbytes && $status) {
return $cnt;
}
return $status;
}
谢谢!
