Question

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.

Using objects will most likely not help (it might even be worse).

What you need to do, in a case such as this one, is re-think :

• either your design : there must be another way to achieve what you want
  • possibly, using another algorithm ?
  • or storing some “temporary data” elsewhere than in memory ? In an SQLite database, for instance ?
• or the language you’ll use for your script
  • PHP is not always the best tool for the job.
