"; //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,$remotefile);// 获取远程文件的修改时间函数 if (!($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($conn); //fget()函数的用法: //ftp_get($conn,$localfile,$remotefile); ?>
