如何实现文件上传 ?
文件上传界面 if($UploadAction){ $UploadAction=0; $TimeLimit=60; /*设置超时限制时间默认时间为 30s，设置为0时为不限时 */ set_time_limit($TimeLimit); If(($Upfile != "none")&& ($Upfile != "")) { $Filepath="d:webwebphp est"; //上载文件存放路径 $FileName=$Filepath.$Upfile_name; if($Upfile_size <1024) //上载文件大小 {$FileSize = (string)$Upfile_size . "字节";} elseif($Upfile_size <(1024 * 1024)) { $FileSize = number_format((double)($Upfile_size / 1024), 1) . " KB"; } else { $FileSize = number_format((double)($Upfile_size/(1024*1024)),1)."MB"; } if(!file_exists($FileName)) { if(copy($Upfile,$FileName)) {unlink($Upfile); echo " "; echo "文件 $Upfile_name 已上载成功！"; echo " "; echo "文件位置：$FileName"; echo " "; echo "文件大小：$FileSize"; echo " "; } else {echo "文件 $Upfile_name上载失败！"; } } else {echo "文件 $Upfile_name已经存在！"; } } else {echo "你没有选择任何文件上载！"; } set_time_limit(30); //恢复默认超时设置 } ?> ACTION = "default.php" METHOD = "POST">
