Thus far, I've built very simple pieces of PHP such as logins, maintaining sessions, writing/reading to/from MySql. My one concern with PHP is the overwhelming "alphabet soup" of functions.

I haven't done anything web-facing with Python just yet, just using it to; parse files, some socket programming - basically getting a feel for the language.

So far, I couldn't say I've run into any issues resulting directly from the languages themselves.

Thanks for the input.
