convert one dimentional array to two dimentional

[vasana]

Hi. I'm a very new php user. Anyone know how to convert one dimentional array to two?

such as :
$one_array[0] = 'powder'
$one_array[1] = '2'
$one_array[2] = '4.5'
$one_array[3] = 'soap'
$one_array[4] = '12'
$one_array[5] = '5.6'

convert it to
$two_array[0][0] ='powder'
$two_array[0][1] ='2'
$two_array[0][2] ='4.5'
$two_array[1][0] ='soap'
$two_array[1][1] ='12'
$two_array[1][2] ='5.6'

Thank you for your help.

Well it all depends on how the data is stored in your array, but if you are dealing with data that is in sets of 3 like what you show above you could do something like this:

$fieldCount=1;
$twoRow=0;
for ($i = 0; $i < count($one_array); $i++) {
   if ($fieldCount == 3) {
      $fieldCount = 1;
      $twoRow++;
   }
   $two_array[$twoRow][] = $one_array[$i];
   $fieldCount++;
}

This will walk through each value in your array (you could use foreach as shown below) and put it into a new multidimensional array broken up into chuncks of 3 values.

$fieldCount=1;
$twoRow=0;
foreach ($one_array as $value) {
   if ($fieldCount == 3) {
      $fieldCount = 1;
      $twoRow++;
   }
   $two_array[$twoRow][] = $value;
   $fieldCount++;
}

Niether of these pieces of code is very robust but you should be able to get the idea.
