Php图像类型上传问题gif png

Question

我有这部分代码，我尝试了一些像“或”和“其他”的东西，但它对我来说不正常。 因此，它适用于.jpg文件格式，上传它很好，当我尝试添加.gif限制1-2mb它没有上传它。 你能帮我吗？

if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") && ($_FILES["uploaded_file"]["size"] < 350000))

我用了

if (($ext == "gif") && ($_FILES["uploaded_file"]["type"] == "image/gif") && ($_FILES["uploaded_file"]["size"] < 2000000))

对于GIF和

if (($ext == "png") && ($_FILES["uploaded_file"]["type"] == "image/png") && ($_FILES["uploaded_file"]["size"] < 1000000))

但它不起作用，所以如果有人可以帮助我，请=）

jpeg代码的完整部分是：

if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {
                  //Check if the file is JPEG image and it's size is less than 350Kb
                  $filename = basename($_FILES['uploaded_file']['name']);
                  $ext = substr($filename, strrpos($filename, '.') + 1);
                  if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") && ($_FILES["uploaded_file"]["size"] < 350000)){
                    //Determine the path to which we want to save this file
                      $newname = dirname(__FILE__).'/upimg/'.$filename;
                      //Check if the file with the same name is already exists on the server
                      if (!file_exists($newname)) {
                        //Attempt to move the uploaded file to it's new place
                        if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) {

检查php.ini文件中的设置：

upload_max_filesize
post_max_size

如果最大尺寸太小，则不会上传文件。 增加大小，看看它是否解决了您的问题。
