PHP的smbclient庫本身并不支持大文件傳輸,但你可以通過以下方法實現(xiàn)大文件傳輸:
以下是一個使用smbclient庫進行分塊傳輸?shù)氖纠?/p>
function smb_chunk_read($connection, $file_id, $offset, $size) {
$data = '';
while ($size > 0) {
$read_size = min($size, 4096);
$result = smb_read($connection, $file_id, $offset, $read_size);
if ($result === False) {
throw new Exception("Failed to read chunk from file.");
}
$data .= $result;
$offset += $read_size;
$size -= $read_size;
}
return $data;
}
function smb_chunk_write($connection, $file_id, $offset, $data) {
$total_chunks = ceil(strlen($data) / 4096);
for ($i = 0; $i < $total_chunks; $i++) {
$start_offset = $offset + ($i * 4096);
$end_offset = min($start_offset + 4096, strlen($data));
$chunk_data = substr($data, $start_offset, $end_offset - $start_offset);
$result = smb_write($connection, $file_id, $offset + ($i * 4096), $chunk_data);
if ($result === False) {
throw new Exception("Failed to write chunk to file.");
}
}
}
// 連接到SMB服務(wù)器
$connection = smb_connect("smb://server/share");
// 打開文件
$file_id = smb_open($connection, "largefile.txt", SMB_O_RDONLY);
// 讀取文件的第一塊
$offset = 0;
$chunk_data = smb_chunk_read($connection, $file_id, $offset, 4096);
// 處理數(shù)據(jù)(例如將其保存到磁盤)
file_put_contents("largefile_chunk.txt", $chunk_data);
// 將文件的第一塊寫回服務(wù)器
$offset = 0;
smb_chunk_write($connection, $file_id, $offset, $chunk_data);
// 關(guān)閉文件和連接
smb_close($file_id);
smb_disconnect($connection);
