Vizor Posted July 31, 2007 Share Posted July 31, 2007 A variable is simply a pointer to the memory where the actual variable contents are stored, the same with a constant, the only difference being that a constant can't be changed. It depends on what you're script is being used for, if it's being used alot then constants are to be avoided as php creates a new instance in the memory for each constant every time the script is run; for example if the script is accessed 5 times at the same time you end up with 5 constants in the memory. Not too sure how variables work in the same level of detail.
