通過二維數組循環播放

Question

我可以像這樣訪問下列值。

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

不過，我需要鞏固這一對其他

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

2件奇怪的事情。該值是字符串，我需要他們小數（小數點後2分），也min和價格的最高和低翻過所有行

Answer 1

嘛打造明顯的方式值的數組將是：

 
$values = array(); 
for($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 
} 

揣摩最大/最小自己

退房foreach循環和字符串/浮充轉換
