Functions vs. Not - Memory Usage?

[spags]

I am wondering if anyone knows how functions take up memory in PHP. For example, I'm re-doing a project that was one huge honkin IF/ELSE statement (about 900 lines) into functions. Some are reused through out the code, a few are not.

I would assume that PHP frees up the memory that a local variable takes up after a function is complete. Yes?

How does PHP allocate memory for a function? at runtime? or when it needs to use it?

And, it all comes down to... am I saving more memory by using functions?

Thanks for any help 🙂

Functions are a good way to structure you code and to actually speed some things up... I don't want to go onto the details of Memory Systems architechture, but fucntions will be allocated segments of memory that will be used while the function is executed and most of it will be trashed (depending on what you want to store after the fucntion has executed, whether it is just the return value, or the variables that were passed to the function too)...

As far as I remmember, memory is allocated at runtime, but I can be mistaken here... anyhow, you should not be worried about this at all, since PHP does not go into System Programming where you start thinking about allocating right ammount of memory to the right tasks... most PHP scripts are fully executed in less than a second... so just relax and have fun 🙂
