上傳圖片到服務器不起作用.jpeg是類型

Question

我正在使用此腳本上傳圖片.jpg &.png類型到服務器和數據庫，但是當談到.jpeg或.JPG它不工作，而不是將文件放在正確的目錄中，並且使用正確的擴展名，它只是在/galleri/uploads/a4b7c7fb0de9c561110c2279f24ec820jpeg.php中自動添加.php文件。

我一直試圖做的是增加這些線路

if ($type == 'image/jpeg') { $filetype = '.jpeg'; } else { $filetype = str_replace('image/', '', $type); } 

if ($type == 'image/jpeg') { $filetype = '.JPG'; } else { $filetype = str_replace('image/', '', $type); } 

，但沒有用..

除了有沒有更好的裁切工具，我可以在這種情況下使用是不是很先進？

這是完整的腳本：

    $mediatype = escape(striptags($_POST['mediatype'])); 
    $title =  escape(striptags($_POST['title']));

    if ($mediatype === 'img') { 
     if(!isset($_POST['p'])) { $_POST['p']= 0; } 

     if($_POST['p'] == 1) { 
      $name =  $_FILES['image']['name'];

試試這個：

<?php 

    ... 

    $name = $_FILES['image']['name']; 
    $temp = $_FILES['image']['tmp_name']; 
    $size = $_FILES['image']['size']; 

    $type = image_type_to_mime_type(exif_imagetype($temp)); // get the real image mime type 

    if ($type == 'image/jpeg') { // jpeg 

     $filetype = '.jpg'; 

    } else if ($type == 'image/png'){ // png 

     $filetype = '.png'; 

    } else { // other image type 

     $filetype = '.' . str_replace('image/', '', $type); // to get .gif for a gif image, for example 

    } 

    ... 

?>
