一个很简单的,常用PHP上次方法,我是从类里给大家拿出来的,直接可以使用,也可以继续完善一下,bkJia视频教程里也详细讲解了PHP上传的方法,大家参考一下

/**
  * 图片上传方法-来源与bkJia中文网
  * $maxsize=500000 = 500k;
  * $updir="up/";
  * $upfile=$_FILES["file_img"];
  */
 public function Get_file_upload($upfile, $maxsize, $updir, $newname = date) {

  if ($newname == date)
   $newname = date("Ymdhs"); //使用日期做文件名
  $name = $upfile["name"];
  $type = $upfile["type"];
  $size = $upfile["size"];
  $tmp_name = $upfile["tmp_name"];

  switch ($type) {
   case image/pjpeg :
   case image/jpeg :
    $extend = ".jpg";
    break;
   case image/gif :
    $extend = ".gif";
    break;
   case image/png :
    $extend = ".png";
    break;
  }
  if (empty ($extend)) {
   echo 文件类型不正确,只能使用JPG GIF PNG 格式;  
  }
  if ($size > $maxsize) {
   $maxpr = $maxsize / 1000;
   echo "警告!上传图片大小不能超过";
  }
  if (move_uploaded_file($tmp_name, $updir . $newname . $extend)) {
   return $newname . $extend;
  }
 }
