使用 ftp_nb_get() 函数断线续传

<?php

// 开始

$ret = ftp_nb_get ($my_connection, "test", "README", FTP_BINARY,

filesize("test"));

// 或: $ret = ftp_nb_get ($my_connection, "test", "README",

// FTP_BINARY, FTP_AUTORESUME);

while ($ret == FTP_MOREDATA) {

// 可以插入其它代码

echo ".";

// 继续传送...

$ret = ftp_nb_continue ($my_connection);

}

if ($ret != FTP_FINISHED) {

echo "下载出错...";

exit(1);

}

?>
