Question

我想在我的上传图片中添加限制file.I 想验证尺寸 500kb.Here 是我的代码。


    if(empty($_FILES["uthu"]["name"]))
        $errors[] = "Thumb was empty";
    if($_FILES["uthu"]["error"] != 0)
        $errors[] = "error uploading Thumbnail";
        $ext = strtolower(substr($_FILES["uthu"]["name"], -4));
    if($ext != ".jpg")
        $errors[] = "upload .jpg for Thumb";

        $fnm1 = time().rand(1111,9999)."_".$_FILES["uthu"]["name"];
        move_uploaded_file($_FILES["uthu"]["tmp_name"], "uploads/".$fnm1);

您可以通过以下代码查看文件大小

// You should also check filesize here. 
if ($_FILES['uthu']['size'] > 500000) {
    $errors[] = "Exceeded filesize limit";
}
