PHP - JSON 编码输出仅包含 1 个 XML 条目而不是多个

PHP - JSON encode output contains only 1 XML entry instead of multiple

上一个post:

好的,我的代码对 1 位客户来说完美运行。现在我 运行 遇到另一个问题,如果我想接收多个客户作为 JSON 输出,我该怎么做?

我在状态为 C 的帐户下创建了第二个条目,并修改了我目前收到的代码部分,基本上从所有状态为 C 的帐户输出 name/email/...。但是我只是收到它看到的第一个。可能哪里弄错了

$document = new DOMDocument();
$document->loadXML($response);
$xpath = new DOMxpath($document);

$json = [];
foreach ($xpath->evaluate('(/eExact/Accounts)') as $account) {
    $json['email'] = $xpath->evaluate('string(Account[@status="C"]/Email)', $account);
    
    $json['first_name'] = $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/FirstName)', $account);
    $json['last_name'] = $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/LastName)', $account);
    $json['billing'] = [
      'first_name' => $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/FirstName)', $account),
      'last_name' => $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/LastName)', $account),
      'postcode'=> $xpath->evaluate('string(Account[@status="C"]/Address[@default="1"]/PostalCode)', $account),
    ];

    // ...
}

$customer = json_encode($json, JSON_PRETTY_PRINT);
echo $customer; 

输出:

{
    "email": "example1@example1.com",
    "first_name": "John",
    "last_name": "Doe",
    "billing": {
        "first_name": "John",
        "last_name": "Doe",
        "postcode": "10000"
    }
}[Finished in 0.4s]

我真正想要的是这样的:[或者换句话说,所有状态为 C 的帐户]

 {
        "email": "example1@example1.com",
        "first_name": "John",
        "last_name": "Doe",
        "billing": {
            "first_name": "John",
            "last_name": "Doe",
            "postcode": "10000"
        }
 {
        "email": "example2@example2.com",
        "first_name": "Steve",
        "last_name": "Doe",
        "billing": {
            "first_name": "Steve",
            "last_name": "Doe",
            "postcode": "20000"
        }

您将在每次迭代时覆盖 $json 数组键。您将其设为一维数组,而您需要的是多维数组(其中每个元素是另一个数组):

foreach ($xpath->evaluate('(/eExact/Accounts)') as $account) {
    $json[] = [
        'email' => $xpath->evaluate('string(Account[@status="C"]/Email)', $account),
        'first_name' => $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/FirstName)', $account),
        'last_name' => $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/LastName)', $account),
        'billing' => [
            'first_name' => $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/FirstName)', $account),
            'last_name' => $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/LastName)', $account),
            'postcode'=> $xpath->evaluate('string(Account[@status="C"]/Address[@default="1"]/PostalCode)', $account),
        ],
    ];
}

这里的关键是 $json[] = ... - 这告诉 PHP 在数组中创建一个新元素并为其分配后面的值。

您正在创建一个数组并在每次循环中覆盖它。有多种追加方法,但使用现有代码,您可以执行如下操作:

foreach ($xpath->evaluate('(/eExact/Accounts)') as $account) {
    $json['email'] = $xpath->evaluate('string(Account[@status="C"]/Email)', $account);        
    $json['first_name'] = $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/FirstName)', $account);
    $json['last_name'] = $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/LastName)', $account);
    $json['billing'] = [
      'first_name' => $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/FirstName)', $account),
      'last_name' => $xpath->evaluate('string(Account[@status="C"]/Contact[@default="1"]/LastName)', $account),
      'postcode'=> $xpath->evaluate('string(Account[@status="C"]/Address[@default="1"]/PostalCode)', $account),
    ];
    // append to your result here
    $result[] = $json;
}
$customer = json_encode($result, JSON_PRETTY_PRINT);
echo $customer;
