README

This library provides a simple URL-safe Base64 encoder/decoder. Nothing fancy, just PHP's standard base64_encode() and base64_decode() functions converted to a URL- and filename-safe alphabet as defined in RFC 4648. None of this is new, I just wanted to have a convenient place to bundle these tools into my projects.

Encoding/Decoding Data

Simply pass your raw or encoded data into the appropriate function:

Base64Url::encode("Hello, world!") => "SGVsbG8sIHdvcmxkIQ"  // *see note
Base64Url::decode("SGVsbG8sIHdvcmxkIQ") => "Hello, world!"

*Note: The Base64 padding characters (=) are removed from the encoded string, but are reconstituted on decode if needed.
