php looping through 2D array

Question

I access the following values like this.

$result->{'HistoricalPricesResult'}->HistoricalPricesResult[0]->Price
$result->{'HistoricalPricesResult'}->HistoricalPricesResult[0]->Low
//next row
$result->{'HistoricalPricesResult'}->HistoricalPricesResult[1]->Price
$result->{'HistoricalPricesResult'}->HistoricalPricesResult[1]->Low

However I need to consolidate this to

$values[0][price]
$values[0][low]
$values[1][price]
$values[1][low]

2 other strange things. The values are strings and I need them to be decimals(2 decimal points) and also the min and the max for price and low accross all the rows

Answer 1

Well the obvious way to build an array of values would be:

$values = array();
for($i = 0; $i < some_maximum_value; $i++) {
   $values[$i] = array(
      'price' => $result->{'HistoricalPricesResult'}->HistoricalPricesResult[$i]->Price,
      'low' => $result->{'HistoricalPricesResult'}->HistoricalPricesResult[$i]->Low,
   );
}

Answer 2

TADAAAAAA!!!!

$values = array();
foreach($result->{'HistoricalPricesResult'}->HistoricalPricesResult as $key => $obj){
    $values[$key]['price'] = $obj->Price;
    $values[$key]['low'] = $obj->low;
}

Answer 3

$myVals = array();
foreach ($result->{'HistoricalPricesResult'}->HistoricalPricesResult as $key => $v)
{
   $myVals[$key]['price'] = 1.0 * $c->Price;  //hoping string has 2 after the decimal
   $myVals[$key]['low'] = 1.0 * $c->Low
}

Try to figure out max/min yourself
