Optimization problem

[fazi]

Hi, I got this code with is slow for 'big' numbers like 1kkk or more can u have any idea how i can speed up calculations ? (by not baying new server ;])

<?php
function gen_time()
{
    list($usec, $sec) = explode(' ', microtime());
    return ((float)$usec + (float)$sec);
}

//generate start time
$start = gen_time();


//items_id, number of items
$Items        = "111,5000000;112,1000;203,50000;113,1000;";

$time_item    = 6666611111;
$left_time    = 10;

  if($Items != 0 && $left_time != 0)
  {
      $time_item        += $left_time;
      $id      = explode(';',$Items);

      foreach($id as $n => $array)
      {
          if(false == empty($array))
          {
              $array             = explode(',',$array);
              $CArray[$n] = array($array['0'],$array['1'],100);
          }
      }
      $Items                    = '';    
      $end           = false;
      $create                = '';
      foreach($CArray as $a => $b)
      {            
          // var_dump($b); - array(3) { [0]=>  string(3) "111" [1]=>  string(5) "50000" [2]=>  int(100) } thats why im using int its incrise a speed a little
          $Type          = (int)$b['0'];
          $Count         = (int)$b['1'];
          $Time          = (int)$b['2'];

       //do this while time is 0 or end of qoute
          while($time_item >= $Time && $end == false)
          {
            if($Count > 0)
            {
                  $time_item -= $Time;
                  ++$create[$Type];
                  --$Count;
            }
            else
            {
                  $end = true;
                  break;
            }
          }
          if($Count != 0)
          {
            $Items .= $Type.",".$Count.";";
          }
    }
  }
  else
  {
    $create        = '';
    $time_item  = 0;
  }

$end = gen_time();

//show time of script generation
echo round($end - $start,3);

?>

I ran the code and get 0.023.. not sure what your problem is here.

You might want to check your use of [man]settype[/man], it's spitting out notices the way you're using it; and it probably isn't necessary at all.

Could you explain what it's supposed to be dong. All I can tell is that with the given input $Items ends up with the value

112,1000;203,50000;113,1000;

(and I get an additional notice message that "111" is an undefined array offset).

112,1000;203,50000;113,1000;

Script updated in first post.

@ Weedpacket
Its a script form a game.

$item its just a mysql SELECT and this what usually u get.

112,1000;

This should generate item 112 1000 depends of time. More time more items will be generated (max is 1000)

soo if add some items to base and wait 3 seconds it could generate 333 and 1000 - 333 update base with actual time and then wait for u to click again if u click after 6s u get 666 items soo script will do 667 - 666 and upgrade base with time and then wait again.

@m@tt

change to

$Items = "111,5000000;112,1000;203,50000;113,1000;";
