Question

我有多个数组，我希望在我的代码

下使用foreach获取特定值

注意：未定义的索引：第52行的transId

$test = array(
    'messages' => Array
    (
        'resultCode' => 'Ok',
        'message' => Array
        (
            'code' => 'I00001',
            'text' => 'Successful',
        ),

    ),
    'transactionResponse' => Array
    (
        'responseCode' => '1',
        'authCode' => 'Z7K31J',
        'avsResultCode' => 'Y',
        'cvvResultCode' => 'P',
        'cavvResultCode' => '2',
        'transId' => '40004672975',
        'refTransID' => Array
        (
        ),

        'transHash' => '163382584395AB06470CF365AD6F7381',
        'testRequest' => '0',
        'accountNumber' => 'XXXX4242',
        'accountType' => 'Visa',
        'messages' => Array
        (
            'message' => Array
                (
                    'code' => '1',
                    'description' => 'This transaction has been approved',
                ),

        ),
        'transHashSha2' => Array
        (
        ),
    ),
);

在我的数组上方，在foreach

中执行$test

我希望显示transid，response，transhash

的显示值

foreach ($test as $key => $value) {  
    $response = $value['resultCode'];
    $transId = $value['transId'];
    $authCode = $value['authCode'];
    $transHash = $value['transHash'];
}

Answer 1

你不需要foreach：

$response = $test['messages']['resultCode'];
$transId = $test['transactionResponse']['transId'];
$authCode = $test['transactionResponse']['authCode'];
$transHash = $test['transactionResponse']['transHash'];

Answer 2

使用array_walk_recursive()，您不必进入数组的每个级别来回显您的值，如下所示：

<?php
  array_walk_recursive($test, function ($item, $key){
    if($key == 'transId' || $key == 'transHash' || $key == 'resultCode'){
        echo $key." => ".$item."<br>";
    }
});

Answer 3

你可以用这个

foreach ($test as $key => $value)
{
   if(!empty($value['message']))
   {
      $response = $value['messages']['resultCode'];
   }
   elseif(!empty($value['transactionResponse']))
   {
        $transId = $value['transactionResponse']['transId'];
        $authCode = $value['transactionResponse']['authCode'];
        $transHash = $value['transactionResponse']['transHash'];
   }
}

如果你想要正确，那么你必须把它带到数组并键入你的transid
