How to pass a binary string without conversion?

Question

PHP

I have a binary string that I received using the `pack` function.
It is necessary to transfer this string via HTTP to another server and process this string as binary there.
I can't think. How to achieve such a result?
Is there anything more elegant than base64?

Answer 1

base64 is the most elegant way to pass binary data for HTTP.
Well, you can try uuencode, but it's older and less elegant.
The direct binary string will be modified, because the HTTP protocol can't pass unreadable characters - they will disappear. Therefore, encoding is required in a format where all unreadable characters are replaced (the size increases by about 30%).
Or use NOT http.
