PHP字节数组到Base64(来自Mssql的字节数组) [英] PHP Byte Array to Base64 (Byte Array From Mssql)

问题描述

我在表上使用Mssql和图像，例如"0xFFD8FFE000104A46494 ....".我认为这是字节数组.

I use Mssql and images on table like "0xFFD8FFE000104A46494...." . I think it is byte array.

我想用PHP将其更改为图像.

And I wanna change it to image with PHP.

我尝试这个；

<?php $resim="0xFFD8FFE000104A46494...."; ?>

<img src="data:image/jpeg;base64,<?php echo base64_encode($resim);?>" />

但是没有显示图像.

推荐答案

您需要将十六进制字符串从SQL Server转换为base64.试试这个，它应该可以工作:

You need to convert the hexadecimal string from SQL Server to base64. Try this, it should work :
