ftp在本地能往遠(yuǎn)程服務(wù)器上傳文件，但是放到服務(wù)器上就不好使了
網(wǎng)站購(gòu)買的萬(wàn)網(wǎng)的虛擬主機(jī)，無(wú)法修改php.ini，也沒(méi)有辦法是用.htaccess來(lái)修改上傳文件大小，故上傳大于10M的文件只好使用ftp方式，代碼如下：
????????$ftp_server=?"xxxx.xxxx.com";
$ftp_user_name=?"xxxx";
$ftp_user_pass=?"xxxxx";
$local_file?=?"D:/Lyb_0/zmsgx.mp4";????????//本地文件
$server_file?=?"htdocs/videos/zmsgx.mp4";??//待上傳后文件所在路徑
$conn_id?=?ftp_connect($ftp_server);?????????//聯(lián)接FTP
$login_result?=?ftp_login($conn_id,$ftp_user_name,$ftp_user_pass)?or?die("Login?error");??//登錄
$fp=fopen($local_file,"r");
ftp_pasv($conn_id,?true);???//開(kāi)啟被動(dòng)模式傳輸?
//上傳參數(shù)
if(ftp_fput($conn_id,$server_file,$fp,FTP_BINARY))?{
????echo?"Successfully?uploaded?$server_file\n";
}else{
????echo?"There?was?a?problem?while?uploading?$file\n";
}
//關(guān)閉連接
ftp_close($conn_id);
fclose($fp);

???????但是這段代碼只在本地好使，放到服務(wù)器上就好使了，fopen($local_file,"r");無(wú)法打開(kāi)本地文件。請(qǐng)問(wèn)如何解決？
------解決思路----------------------
你先確認(rèn)?fopen?是否可用
在服務(wù)器上所謂“本地文件”是指服務(wù)器上的文件

所以你使用?ftp?繞過(guò)?upload?限制的做法，是不現(xiàn)實(shí)的
------解決思路----------------------
$local_file

這個(gè)無(wú)法取到本地文件吧。
