Hmmm ok ill try some things tomo and get back to yas.

Also a file and database will not work as it will just retrieve the value, but still the large amout of iterations are require and hence the same resources are used.

Its like a once use program nothing major more of an experiement for family.

Can anyone answer the max_execution_time = 30 question?

Also niek_e you sound very knowledgable very nice work

Thanks, Goodnight

PS: Its not a hog as such It needs to do alot of calculations.

max_execution_time is used if you have a script which takes more than 30 seconds to execute. When you set max_execution_time as 0, the execution time of the script is removed. That's what I use when I have a process a large csv file. But I don't think it will work in this case.

Thanks, but I'm actually an Embedded engineer, which means I like playing with bits and bytes. For PHP questions you shouldn't be paying too much attention to me Nav33n would be the one to listen to in this thread

Not exactly. Writing to a DB and retrieving data will use a lot of CPU time and HD-space, but you wouldn't need an enormous amount of memory. A MB or two would be enough

Lol.. no.. I got to know few things after reading your posts ! I wasn't aware of the 'in depth bits and bytes calculation' ! electronics! eh ?

If you write to a file or db and call set_time_limit every x number of iterations and use your memory resources wisely by utilizing disc space, you could go all day.
