Comparing Base64 and Base62
I need to pass data through a URL query and will first Base64 or Base62 encode it.
I have three questions:
1. What is the difference between Base64 or Base62?
2. Do both Base64 and Base62 encode data in a way that is URL query safe?
3. Which is space efficient (Takes less bytes)? Base64 or Base62?

Forgot to mention - Depending on what data you're using URL encoding can be horribly inefficient. base-64 adds a fixed and consistent 33% overhead, but URL encoding can add anywhere between 0 and 300% overhead, depending on your data. Whether this is relevant also depends if URL length is a problem - 2k is about the safe limit.
If anything is above 2k, it should not be used in any URL related activities if you ask me. Good point for the overhead.
I have a few implementations of base62 somewhere - none in java though - the only one I ever found in Java that at least was working well enough was doing it by going through Base64 and then to Base62 (and on the way back from 62 to 64 to decoded)

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
