php - 使用 PHP 和 HTML 将字节数组转换为图像

Question

我正在使用 PHP 从 SOAP 服务检索数据，其中一部分是用 base64 编码的图像字节数组，我想在浏览器中显示该图像。数据检索步骤工作正常，但我找不到在浏览器中显示此图像的单一方法。
假设字节数组在 PHP 中存储为 $byteArray:

$img = "<img src= 'data:image/jpeg;base64, $byteArray' />";
print($img);

我希望该代码能够在浏览器中显示图像，但浏览器的解析器总是失败。知道我做错了什么吗？

我在这里使用的 byteArray 示例是:“[B@14a3da8”

提前致谢， 布莱恩
