php Variables...

[friedstingray]

I was wondering,

say if i have a $total_cost variable to calculate the price for a user... and if 2 users were to be viewing the page at the same time,

will this variable be unique to each user or will the variable content be the same for both user?

thanks

are they choosing different options from somewhere, then they will certainly be different
