Can I use a hash sign (#) for commenting in PHP?

Question

I have never, ever, seen a PHP file using hashes (#) for commenting. But today I realized that I actually can! I\'m assuming there\'s a reason why everybody uses

Answer 1

Is there any reason, aside from personal preference, to use // rather than # for comments?

I came here for the answer myself, and its good to know there is NO code difference.

However, preference-wise one could argue that you'd prefer the 'shell->perl->php' comment consistency vs the 'c->php' way.

Since I did approach php as a poor man's webby perl, I was using #.. and then I saw someone else's code and came straight to SO. ;)
