PHP vs Javascript

What are the similarities and differences between these two languages?

What i've gathered so far

They're both web based scripting languages.
PHP is an open source alternative to Microsoft's. It is a recursive acronym for PhpHypertextProcessing.

What i'd like to know is what can you do in JS but not in PHP and vice versa. Also, could Anusymous be written in JS ?

Listen fag, we have no way of knowing when (or where) on earth you've said that, probably a lot of different times, in different locations. But we have no way of knowing do we. The fact is MILKRIBS4k is right, as usual I might add, and your trolling is epic fail type logic because of your pussy choice to stay anonymous.
