现在我正在尝试显示这样的图像...

<img src="data:image/jpeg;base64,<?php echo $profile_image;?>">

但它不显示。我在哪里犯了错误。

Answer 1

去掉 0x 然后使用 hex2bin()或 pack() 获取二进制表示，然后再次对其进行 base64_encode。

 $hex = substr($hex, 2);
 $binary =  pack("H*", $hex);

输出方式:

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