我想将图像从它的 url 转换为 base64.

I want to convert image from its url to base64.

推荐答案

要创建数据url吗?然后，您需要 MIME-Type 和一些其他附加信息(请参阅 Wikipedia).如果不是这种情况，这将是图像的简单 base64 表示:

Do you want to create a data url? You need a MIME-Type and some other additional information then (see Wikipedia). If this is not the case, this would be a simple base64 representation of the image:

$b64image = base64_encode(file_get_contents('path/to/image.png'));
