i need a structure like this

array(){ [0] => array(){ [0] => array(){ // this array will have 'n' values(n is large, like 2000) } [1] => array(){ // this array will have 'n' values(n is large, like 2000) } } . . . . [n] => ............

n arrays will each have a 2 element array, where each element has an array of n values.

I used $list[$m][0][$n] and $list[$m][1][$n] inside 2 for loops where $m,$n vary from 0...2000

this crosses the allowed memory size.. i can change the size in php.ini, but i want to optimize my memory usage and not change the limit.

will using objects help ?

Please provide some sample code to understand. Thank you.
