Question

我在上传图片方面遇到了一些问题。我想从表中存储和检索图像，但是当我尝试获取图像时，它并没有显示。只有破碎的图像图标。但是，如果我通过phpmyadmin手动上传图像，它会显示图像。我的表格行的类型是blob。我完全糊涂了。任何人都可以帮忙。

我的代码很简单：

$pdo = new PDO('mysql:dbname=database_name;host=localhost', 'username', 'password',
                array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'));

              $imageName = mysql_real_escape_string($_FILES["image"]["name"]);
              $imageData = addslashes(file_get_contents($_FILES["image"]["tmp_name"]));
              $imageType = mysql_real_escape_string($_FILES["image"]["type"]);

              $stmt = $pdo->prepare('INSERT INTO image (name,image) VALUES (:name,:image)');
              $stmt->execute(array('name' => $imageName, 'image' => $imageData));
              echo "Image Uploaded";


              $res = mysql_query("SELECT * FROM image "); 
              while ($row = mysql_fetch_assoc($res)) 
              {                                                  
                echo "<img src=data:image/jpeg;base64," . (base64_encode(($row['image']))) . " style='width:60px;height:60px;'>";
              }

尝试删除验证，使用预准备语句，不需要它。

              $pdo = new PDO('mysql:dbname=database_name;host=localhost', 'username', 'password',
                array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'));

              $imageName = $_FILES["image"]["name"];
              $imageData = file_get_contents($_FILES["image"]["tmp_name"]);
              $imageType = $_FILES["image"]["type"];

              $stmt = $pdo->prepare('INSERT INTO image (name,image) VALUES (:name,:image)');
              $stmt->execute(array('name' => $imageName, 'image' => $imageData));
              echo "Image Uploaded";


              $res = mysql_query("SELECT * FROM image "); 
              while ($row = mysql_fetch_assoc($res)) 
              {                                                  
                echo "<img src=data:image/jpeg;base64," . (base64_encode(($row['image']))) . " style='width:60px;height:60px;'>";
              }
