PHP array loop, accessing by numeric index

Question

I have two arrays at the bottom, I'm looking to output their values by a numeric index. Seems so simple yet I cannot get it to work for the life of me. I'm nesting these into a few other foreach loops.

 $x = $ppro_model->orderedByDate($val->ProdCode);
                          $xx = $ppro_model->receivedByDate($val->ProdCode);
                          $ordQty = arrayDateBuilder($x, 'ordQUANTITY', $daterange);
                          $recQty = arrayDateBuilder($xx, 'recQUANTITY', $daterange);

$ordQty and $recQty will ALWAYS have the same amount of elements. So ideally I would like to be able to do the following:

 for($i = 0; $i <= count($ordQty); $i++){
                        echo "<td>";
                        echo $ordQty['recQUANTITY'][$i];
                        echo $recQty['ordQUANTITY'][$i];
                        echo "<td>";
                    }

but I'm definitely doing something wrong. Any advice would be appreciated.

I also tried:

  echo $ordQty[$i];

to not avail.

array (size=7)
  0 => 
    array (size=2)
      'DATE' => string '20141110' (length=8)
      'ordQUANTITY' => string '55.00' (length=5)
  1 => 
    array (size=2)
      'DATE' => string '20141111' (length=8)
      'ordQUANTITY' => string '80.00' (length=5)
  2 => 
    array (size=2)
      'DATE' => string '20141112' (length=8)
      'ordQUANTITY' => string '70.00' (length=5)
  3 => 
    array (size=2)
      'DATE' => string '20141113' (length=8)
      'ordQUANTITY' => string '135.00' (length=6)
  4 => 
    array (size=2)
      'DATE' => string '20141114' (length=8)
      'ordQUANTITY' => string '70.00' (length=5)
  5 => 
    array (size=2)
      'DATE' => string '20141115' (length=8)
      'ordQUANTITY' => string '120.00' (length=6)
  6 => 
    array (size=2)
      'DATE' => string '20141116' (length=8)
      'ordQUANTITY' => string '0' (length=1)

then one like:

array (size=7)
  0 => 
    array (size=2)
      'DATE' => string '20141110' (length=8)
      'recQUANTITY' => string '0' (length=1)
  1 => 
    array (size=2)
      'DATE' => string '20141111' (length=8)
      'recQUANTITY' => string '0' (length=1)
  2 => 
    array (size=2)
      'DATE' => string '20141112' (length=8)
      'recQUANTITY' => string '0' (length=1)
  3 => 
    array (size=2)
      'DATE' => string '20141113' (length=8)
      'recQUANTITY' => string '0' (length=1)
  4 => 
    array (size=2)
      'DATE' => string '20141114' (length=8)
      'recQUANTITY' => string '0' (length=1)
  5 => 
    array (size=2)
      'DATE' => string '20141115' (length=8)
      'recQUANTITY' => string '0' (length=1)
  6 => 
    array (size=2)
      'DATE' => string '20141116' (length=8)
      'recQUANTITY' => string '0' (length=1)

as per Barmar's answer, use foreach to make your life easy. — Mike 'Pomax' Kamermans

You had your array expressions backward, it should be $ordQty[$i]['ordQUANTITY']. Also, your loop condition was wrong, it should be $i < count($ordQty), not <=, since array indexes go from 0 to count-1.

It can be simplified a bit using foreach.

foreach ($ordQty as $i => $ordElt) {
    echo "<td>";
    echo $ordElt['ordQUANTITY'];
    echo $recQty[$i]['recQUANTITY'];
    echo "<td>";
}
