Question

当我执行以下代码时，图像不会显示在浏览器中，而是显示非ASCII符号和字符。很少的行如下：

JFIF6Photoshop 3.08BIMgqarIDeY1blFS2krGbsOU��ICC_PROFILElcmsmntrRGBXYZ�）9acspAPPL��-lcms 说明^ CPRT \ wtpthbkpt | rXYZgXYZbXYZrTRC @ GTRC @ BTRC @ descc2textFBXYZ ��-XYZ3�XYZo�8��XYZb��XYZ $��curv��c�k�？Q4！�）�2;�FQw]�kpz��|�i�}��0��C！ $（％2％（， - / 0 /＃484.7 ./ç

我在这里做错了什么？

<?php
session_start();

if (isset($_SESSION['logSyscuruser'])) {
// logged in
$id = $_SESSION['logSyscuruser'];


$imgLocation = '/Applications/XAMPP/im/';

include "include/specificproductDB.php";
$data = new specificPro();

  $out = $data->select($query, $id, $pId);
  $count = count($out);


}

else
{
  //not logged in
header("Location: loginSystem/login.php", true, 302);
die();
}



?>

    // Print the image data
    readfile($imgPath);
    }

   else

    header('HTTP/1.0 403 Forbidden');

   }

   echo "<br><br>";

  }

readfile函数以非ASCII字符返回文件内容
