multi-dimensional arrays?

leon77

hello, i'm extremely new
here, however i was wondering
if anyone could help me?

i'm trying to create a multi-dimensional array
using a few variables and loops.

i'm trying to create a stock simulation chart,
and i need to fill a db with random activity

based on: numberOfDays, numberOfTradesPerDay,
changeOfPricePerTrade, timeStampsForEachTrade

i'll probably use these variables for the form

$days = "";
$tradesPerDay = "";
$startPrice = "";
$upLimit = "";
$downLimit = "";
$timeStamp = "";

anyhelp on creating multi's with loops will do wonders for me
this way i dont have to fill the db by hand.

thanks
leon

Well, here's an array with double int indices:

$results = array();

for ($i = 0; $i <= $theNumberOfRows; $i++) {
          for ($j = 0; $j <= $theNumberOfColumns; $j++) {
                  $result[$i][$j] = $whatEverYouWant // random numbers, an index, description, whatever)
          }
}

here's one with rows as int indices, each row being filled with an array:

$results = array();

for ($i = 0; $i <= $theNumberOfRows; $i++) {
          $results[$i] = array($key1 => $value1, $key2 => $value2, ....) // Note that you can leave out "$keyX =>" if you simply want int indices
}

Let me know if that didn't help
