Re: [PHP] Size of Arrays

[Galen]

Should anyone be planning experiments or projects with large arrays, 
use a for() loop instead of a foreach() loop when working with your 
array. And be sure to count the array, stick that result into a 
variable, then compare against the variable instead of running the 
count() again.

On huge arrays (hundreds of thousands of elements, three dimensions, 
several megabytes) the performance impact is huge! The downside is 
you'll probably have to use numeric keys instead of associative, but 
for big arrays, numeric keys will probably also keep more memory free 
and improve performance a bit.

Good luck with your arrays!
