Question

我遵循了教程，下面的代码用于在数据库中插入图像。我想上传PDF文件而不是图片使用代码我不知道要将PDF文件插入数据库需要更改什么。我找到了另一个有位置的教程。我还想允许用户在任何位置/文件夹中上传PDF。

这是将图像插入数据库的实际代码。我也想上传pdf文件

<?php
$msg = "";
if (isset($_POST['upload'])) {
   if(getimagesize($_FILES['image']['tmp_name']) == FALSE)
   {
    echo "Please Select an image.";
   }
   else {
    $image = addslashes($_FILES[''])
    $image = addslashes($_FILES['image']['tmp_name']);
    $name = addslashes($_FILES['image']['name']);
    $image = file_get_contents($image);
    $image = base64_encode($image);
    saveimage($name,$image);
   }
}
displayimage();
function saveimage($name,$image)
{
$servername = "localhost";
    $username = "id834551_teacherss";
    $password = "jeromelim";
    $dbname = "id834551_teacher";

    // Create connection
    $conn = new mysqli($servername, $username, $password, $dbname);
    $query = "INSERT INTO images (name,images) values ('$name','$image')";
        if ($conn->connect_error) {

代码已更新...

 <?php
$msg = "";

$tmp_file=$_FILES['image']['tmp_name'];
if($tmp_file){

      $img_name=basename($_FILES['image']['name']);
      $ext = strtolower(substr(strrchr($img_name, "."), 1));
      $ext1=".".$ext;

      $allowed = array('.pdf');

      if(in_array($ext1, $allowed)){

      // Update Path to upload on server

      $img_path="";
      move_uploaded_file($tmp_file,$img_path);
      saveiFILE($img_name,$img_path);


     }else{
         $output_message="Uploaded File seems to be Undefined Type";
     }

}
function saveFILE($name,$image)
{
$servername = "localhost";
    $username = "id834551_teacherss";
    $password = "jeromelim";
    $dbname = "id834551_teacher";

    // Create connection
    $conn = new mysqli($servername, $username, $password, $dbname);
    $query = "INSERT INTO images (name,images) values ('$name','$image')";
        if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    } 

    $result = mysqli_query($conn,$query);
    if($result) {
        echo "<br/> fILE uploaded.";
    }
    else {
