从上传的文件创建Base64而不保存本地php

Question

I need to send a file in base 64 format through a SOAP service. I cannot save the file locally. Is there a way to convert an uploaded file and send it through in one instance, without saving it?

I initially thought it was as easy as:

$base64file = base64_encode($_FILES["cv"]["tmp_name"]);

But that doesn't seem to be working great.

Answer 1

The problem with your code is that you are encoding the filename, not the file content.

Use this to open the file and convert it to base64:

$base64file = base64_encode(file_get_contents($_FILES["cv"]["tmp_name"]));

Then you can send it back to the client. Just double check that the Soap server does not double base64 encode the string.
