我有数组$roomResponse:
Array
(
[0] => Array
(
[0] => stdClass Object
(
[roomCategory] => Standard Room - Double
[paxes] => Array
(
[0] => stdClass Object
(
[paxType] => Adult
[age] => 30
)
[1] => stdClass Object
(
[paxType] => Adult
[age] => 30
)
[2] => stdClass Object
(
[paxType] => Child
[age] => 11
)
)
[totalRoomRate] => 280
[ratesPerNight] => Array
(
[0] => stdClass Object
(
[date] => 2015-06-08
[amount] => 40
)
[1] => stdClass Object
(
[date] => 2015-06-09
[amount] => 40
)
[2] => stdClass Object
(
[date] => 2015-06-10
[amount] => 40
)
)
)
[1] => stdClass Object
(
[roomCategory] => Standard Room - Double
[paxes] => Array
(
[0] => stdClass Object
(
[paxType] => Adult
[age] => 30
)
[1] => stdClass Object
(
[paxType] => Child
[age] => 11
)
[2] => stdClass Object
(
[paxType] => Child
[age] => 11
)
)
[totalRoomRate] => 274
[ratesPerNight] => Array
(
[0] => stdClass Object
(
[date] => 2015-06-08
[amount] => 40
)
[1] => stdClass Object
(
[date] => 2015-06-09
[amount] => 40
)
[2] => stdClass Object
(
[date] => 2015-06-10
[amount] => 40
)
)
)
)
如何提取roomCategory和totalRoomRate。上面的数组包含来自两个房间的信息。我想使用$roomCategory[][]和$totalRoomRate[][]
我试过下面的foreach，但它不起作用，它返回空数组。
foreach ($roomResponse as $camere) {
$roomCategory[][] = $camere->roomCategory;
$totalRoomRate[][] = $camere->totalRoomRate;
感谢
试试这个
<?php
foreach($roomResponse[0] as $key => $value){
print_r($key) // Here the keys
print_r($value) // Here the values
}
?>
这应该可以让您根据需要获取东西：
// Reconstruct for testing...
$oRoom1 = new stdClass;
$oPaxes1 = new stdClass;
$oPaxes2 = new stdClass;
$oPaxes3 = new stdClass;
$oPaxes1->paxType = 'Adult';
$oPaxes1->age = '30';
$oPaxes2->paxType = 'Child';
$oPaxes2->age = '15';
$oPaxes3->paxType = 'Adult';
$oPaxes3->age = '30';
$oRates1 = new stdClass;
$oRates2 = new stdClass;
$oRates3 = new stdClass;
$oRates1->date = '2015-06-08';
$oRates1->amount = 40;
$oRates1->date = '2014-06-08';
$oRates1->amount = 50;
$oRates1->date = '2013-06-08';
$oRates1->amount = 20;
$aRatesPerNight[ 0 ] = $oRates1;
$aRatesPerNight[ 1 ] = $oRates2;
$aRatesPerNight[ 2 ] = $oRates3;
$oRoom1->roomCategory = 'Standard Room - Double';
$oRoom1->paxes[ 0 ] = $oPaxes1;
$oRoom1->paxes[ 1 ] = $oPaxes2;
$oRoom1->paxes[ 2 ] = $oPaxes3;
$oRoom1->totalRoomRate = 280;
$oRoom1->ratesPerNight = $aRatesPerNight;
$aComplex[] = $oRoom1;
$aComplex[] = $oRoom1;
$iCountRooms = count( $aComplex );
for( $i = 0; $i < $iCountRooms; ++$i )
{
foreach( $aComplex[ $i ] as $sRoom => $aRoomAttributes )
{
if( $sRoom = 'roomCategory' )
{
echo 'Room Category is: ' . $aComplex[ $i ]->$sRoom;
echo '<br />';
}
if( $sRoom = 'totalRoomRate' )
{
echo 'Total Room Rate is: ' . $aComplex[ $i ]->$sRoom;
echo '<br />';
}
}
}
// How can i pull roomCategory and totalRoomRate.
echo '<pre>';
var_dump( $aComplex );
echo '</pre>';
foreach ($roomResponse[0] as $camere) {
