问题是BLOB数据返回从我的服务器错误。

The problem is the blob data returns wrong from my server.

    <?php

       $select = "SELECT `data` 
               FROM  `sandbox`.`photos` 
               WHERE `id` = 4
               LIMIT 0 , 1";

        $result = mysql_query($select, $connection);



         while($row = mysql_fetch_array( $result )){

           $blob_data = $row[0];

           echo "$blob_data";

           }

    ?>

的问题是，这retuns 5.533782782 * E

The problem is that this retuns 5.533782782 * E.

我如何认为这是一个形象呢？我需要DEEN code呢？

How do I view this as an image? Do I need to deencode it?

推荐答案

试试这个：

echo '<img src="data:image/png;base64,'.base64_encode($blob_data).'">';
