php實現檔案的自動ftp更新

php實現的使用ftp自動更新上傳檔案的代碼，有需要的朋友，可以參考下。 完整代碼。 Mirror update '; exit;}echo "Connected to $host. ";@ $result=ftp_login($conn,$user,$password); if(!$result) { echo "Error: 使用者 $user 登入失敗。 "; ftp_quit($conn); exit; } echo "login as $user "; //check file times to see if an update is required echo 'Checking file time....'; if(file_exists($localfile)) { $localtime=filetime($localfile); echo 'Local file last updated'; echo date('G:i j-M-Y',$localtime); echo ' '; } else $localtime=0; $remotetime=ftp_mdtm($conn,$remotefile);// 擷取遠程檔案的修改時間函數 if (!($remotetime>=0)) { echo 'Can/'t access remote file time. '; $remotetime=$localtime+1; //make sure of an update } else { echo 'Remote file last updated'; echo date('G:i j-M-Y',$remotetime); echo ' '; } if(!($remotetime>$localtime)) { echo 'Local copy is up to date. '; exit; } //download file echo 'Getting file from server.... '; $fp=fopen($localfile,'w'); if(!$success=ftp_fget($conn,$fp,$remotefile)); { echo 'Error:Could not download file'; ftp_quit($conn); exit; } fclose($fp); echo "File download successfully"; //close connection to host ftp_quit($conn);//fget()函數的用法： //ftp_get($conn,$localfile,$remotefile);?>
