如何创建用于从任何设备上传文件的PHP rest api

Question

我正在创建一个API来注册用户。我已成功注册，但图像未上传。我在谷歌上搜索了一些关于file_put_contet((的信息，但不知道实现它的正确方法

用户已成功注册，但图像未上载到服务器。

要使用API上传图像，最合适的方法是在Json请求中传递base64编码的图像数据，然后使用file_put_contents()将base64编码字符串解码为文件。

$img_info = explode(',',$data['photo']);
$image_content = base64_decode($img_info[1]);
$img_extension = substr($img_info[0], 11, 3);
$img_filename = "images/passport_photo/some_random_text".$img_extension;
file_put_contents($img_filename, $image_content);
//apply your filters of size, extensions before uploading the image

但是base64不是上传大尺寸图像的好主意。首先上传图片，然后在json请求中传递图片URL。
