意外（T_VARIABLE）

Question

我有一个PHP图像上传脚本，它将图像数据上传到MySQL服务器。它给了我一个意想不到的T_VARIABLE，但看起来我的所有分号都存在。有人可以帮帮我吗？

<?php
$username = "username";
$description = "description";
// Check if image file is a actual image or fake image

if(isset($_FILES['image'])){ 
    $check = getimagesize($_FILES["image"]["tmp_name"]);

    if($check !== false) {
         echo "File is an image - " . $check["mime"] . ".";
         $uploadOk = 1;
         $image = file_get_contents($_FILES["image"]["tmp_name"]);
         $con = mysqli_connect("localhost", "root", "root", "familyConnections");

         $query = "INSERT INTO images (userName, image, description) VALUES ($username, $image, $description)";
         $query = mysqli_query($con, $query);

         if($query != 0){
               echo "ERROR something went wrong";
         }else {
            echo "IT WORKED".$query;
         }

         } else {
             echo "File is not an image.";
             $uploadOk = 0;
      }
    }
?>

我得到的结果是
