從陣列中獲得值用foreach

Question

我的格式陣列這樣

 

Array ( 

[0] => stdClass Object ([subscriptionContractId] => 20878 [merchantId] => 10062 [merchantName] => LinkIT360 [startDate] => 2015-07-02 03:27:39.000 [endDate] => 2015-07-04 03:27:39.000 [operatorCode] => 60201 [operatorName] => Mobinil-EGY [status] => 2 [isVerified] => 1 [initialPaymentproductId] => [initialPaymentDate] => [recurringPaymentproductId] => game_sku_1 [productCatalogName] => Game [autoRenewContract] => 1 [msisdn] => 201200000000 [customerAccountNumber] => 201200000000 [subscriptionContractName] => Game [nextPaymentDate] => 2015-07-03 03:27:39.000 [lastPaymentDate] => 2015-07-02 03:27:39.000 [subscriptionContractHistory] =>Array ([0] => stdClass Object ([subscriptionContractId] => 20878 [status] => 2 [isMerchantNotified] => 1 [paymentTransactionId] => [date] => 2015-07-01 03:27:53.290)) [subscriptionContractLogs] =>) 

[1] => stdClass Object ([subscriptionContractId] => 20861 [merchantId] => 10062 [merchantName] => LinkIT360 [startDate] => 2015-07-01 11:31:47.000 [endDate] => 2015-06-30 11:32:05.150 [operatorCode] => 60201 [operatorName] => Mobinil-EGY [status] => 5 [isVerified] => 1 [initialPaymentproductId] => [initialPaymentDate] => [recurringPaymentproductId] => game_sku_1 [productCatalogName] => Game [autoRenewContract] => 1 [msisdn] => 201200000000 [customerAccountNumber] => 201200000000 [subscriptionContractName] => Game [nextPaymentDate] => [lastPaymentDate] => 2015-07-01 11:31:47.000 [subscriptionContractHistory] => Array ([0] => 
stdClass Object ([subscriptionContractId] => 20861 [status] => 2 [isMerchantNotified] => 1 [paymentTransactionId] => [date] => 2015-06-30 11:31:55.530) [1] => stdClass Object ([subscriptionContractId] => 20861 [status] => 5 [isMerchantNotified] => 1 [paymentTransactionId] => [date] => 2015-06-30 11:32:05.977)) [subscriptionContractLogs] =>) 

[2] => stdClass Object ([subscriptionContractId] => 20860 [merchantId] => 10062 [merchantName] => LinkIT360 [startDate] => 2015-07-01 11:29:37.000 [endDate] => 2015-06-30 11:30:19.887 [operatorCode] => 60201 [operatorName] => Mobinil-EGY [status] => 5 [isVerified] => 1 [initialPaymentproductId] => [initialPaymentDate] => [recurringPaymentproductId] => game_sku_1 [productCatalogName] => Game [autoRenewContract] => 1 [msisdn] => 201200000000 [customerAccountNumber] => 201200000000 [subscriptionContractName] => Game [nextPaymentDate] => [lastPaymentDate] => 2015-07-01 11:29:37.000 [subscriptionContractHistory] => Array ([0] => stdClass Object ([subscriptionContractId] => 20860 [status] => 2 [isMerchantNotified] => 1 [paymentTransactionId] => [date] => 2015-06-30 11:30:10.267) [1] => stdClass Object ([subscriptionContractId] => 20860 [status] => 5 [isMerchantNotified] => 1 [paymentTransactionId] => [date] => 2015-06-30 11:30:20.687)) [subscriptionContractLogs] =>) 

[3] => stdClass Object ([subscriptionContractId] => 20859 [merchantId] => 10062 [merchantName] => LinkIT360 [startDate] => 2015-07-01 11:27:33.000 [endDate] => 2015-06-30 11:27:57.683 [operatorCode] => 60201 [operatorName] => Mobinil-EGY [status] => 5 [isVerified] => 1 [initialPaymentproductId] => [initialPaymentDate] => [recurringPaymentproductId] => game_sku_1 [productCatalogName] => Game [autoRenewContract] => 1 [msisdn] => 201200000000 [customerAccountNumber] => 201200000000 [subscriptionContractName] => Game [nextPaymentDate] => [lastPaymentDate] => 2015-07-01 11:27:33.000 [subscriptionContractHistory] => Array ([0] => stdClass Object ([subscriptionContractId] => 20859 [status] => 2 [isMerchantNotified] => 1 [paymentTransactionId] => [date] => 2015-06-30 11:27:42.173) [1] => stdClass Object ([subscriptionContractId] => 20859 [status] => 5 [isMerchantNotified] => 1 [paymentTransactionId] => [date] => 2015-06-30 11:27:58.467)) [subscriptionContractLogs] =>) 
 

我想利用這個值[subscriptionContractId] => 20859 PFB我的代碼

 

foreach($getContract as $key =>$value) { 
    $cancel = $getContract[$key]->subscriptionContractId;  
    $this->data['res'] = $cancel; 
} 
 

上面的代碼只顯示記錄的單個值，同時記錄大約是27條記錄。

和另一個代碼，我嘗試用初始化數組PFB來糾正。

 

$cancel = array() 
    foreach($getContract as $key =>$value) { 
    $cancel[] = $getContract[$key]->subscriptionContractId;  
    $this->data['res'] = $cancel; 
    } 
 

我只需要值，陣列如20879等的eventhough我使用雙迴路來提取特定的陣列僅顯示在最後的記錄10663.

請幫助

您可以修改代碼如下（見php documenation about foreach更多背景）：

$cancel = array(); 
foreach($getContract as $value) { 
    $cancel[] = $value->subscriptionContractId;  
    ... 
} 

這樣，在每一次迭代中，$value都會從您的getContract數組中分配一個值，它的鍵被省略。然後，您可以將值subscriptionContractId存儲在您的$cancel陣列中，以執行您打算執行的任何操作。

注：briosheje是正確的進線：

$this->data['res'] = $cancel; 

$this->data['res']在每次迭代覆蓋。當你用你的$cancel數組覆蓋它時，你的代碼仍然可以工作，但是你在這裏做了不必要的工作，因爲你的數組在下一次迭代時可能會受到進一步的改變。

我的建議是推動這一行後你的循環結束支架，讓您的結果保存一次：

... 
foreach($getContract as $value) { 
    ... 
} 
$this->data['res'] = $cancel;
