remove whitespaces from base64 encoded string when posting

Question

I need to remove white spaces from a base64 encoded file. When Base64 gets POSTed, and I get more white spaces in the output string. Where did these white spaces coming

How do I remove these whitespaces?

Answer 1

When Base64 gets POSTed, all pluses(+) are parsed as spaces. So I used str_replace to convert the spaces back to pluses. This saved my time
