PHP数组获取值

Question

N00B 在这里，我有以下 php 数组输出，对于我来说，我无法提取数组值 - 我已经遍历数组并尝试输出$array['AmountPaid']. 我注意到在其他帖子中，数组有一个 => 而不是 : 来将键与值分开，然后使用它：$array=>AmountPaid

{

  "Type": "ACCREC",

  "Contact": {

    "ContactID": "37918a06-92f6-4edb-bfe0-1fc041c90f8b",

    "Name": "Boom FM",

    "ContactPersons": [],

    "Addresses": [],

    "Phones": [],

    "ContactGroups": [],

    "HasAttachments": false,

    "HasValidationErrors": false

  },

  "LineItems": [],

  "Date": "2020-04-08",

  "DueDate": "2020-04-21",

  "LineAmountTypes": "Exclusive",

  "InvoiceNumber": "INV-0010",

  "Reference": "Training",

  "CurrencyCode": "USD",

  "Status": "PAID",

  "SubTotal": 500,

  "TotalTax": 41.25,

  "Total": 541.25,

  "InvoiceID": "4c4db294-3633-45cd-8706-f0b3b0079609",

  "HasAttachments": false,

  "IsDiscounted": false,

  "Payments": [],

  "Prepayments": [],

  "Overpayments": [],

  "AmountDue": 0,

  "AmountPaid": 0,

  "FullyPaidOnDate": "2020-04-19",

  "AmountCredited": 541.25,

  "UpdatedDateUTC": "2008-12-20T18:38:32+01:00",

  "CreditNotes": [

    {

      "Date": "2020-04-19",

      "LineItems": [],

      "Total": 541.25,

      "CreditNoteID": "602f5486-664e-492f-b4d1-e12df1d4b8ba",

      "CreditNoteNumber": "CN-0014",

      "AppliedAmount": 541.25,

      "HasAttachments": false,

      "HasErrors": false

    }

  ],

  "HasErrors": false

}

Answer 1

它是一个 JSON 字符串而不是 PHP 数组。要转换，您可以这样做：    $string = '{ "Type": "ACCREC", "Contact": { "ContactID": "37918a06-92f6-4edb-bfe0-1fc041c90f8b", "Name": "Boom FM", "ContactPersons": [], "Addresses": [], "Phones": [], "ContactGroups": [], "HasAttachments": false, "HasValidationErrors": false }, "LineItems": [], "Date": "2020-04-08", "DueDate": "2020-04-21", "LineAmountTypes": "Exclusive", "InvoiceNumber": "INV-0010", "Reference": "Training", "CurrencyCode": "USD", "Status": "PAID", "SubTotal": 500, "TotalTax": 41.25, "Total": 541.25, "InvoiceID": "4c4db294-3633-45cd-8706-f0b3b0079609", "HasAttachments": false, "IsDiscounted": false, "Payments": [], "Prepayments": [], "Overpayments": [], "AmountDue": 0, "AmountPaid": 0, "FullyPaidOnDate": "2020-04-19", "AmountCredited": 541.25, "UpdatedDateUTC": "2008-12-20T18:38:32+01:00", "CreditNotes": [ { "Date": "2020-04-19", "LineItems": [], "Total": 541.25, "CreditNoteID": "602f5486-664e-492f-b4d1-e12df1d4b8ba", "CreditNoteNumber": "CN-0014", "AppliedAmount": 541.25, "HasAttachments": false, "HasErrors": false } ], "HasErrors": false }'    $data = json_decode($string, true); //Second parameter forces conversion to array    var_dump($data);

好吧，我会因为我的回答而被钉牢，因为我真的把它混为一谈，但它有效：$result = "Xero 会计 API 的数组输出"; $json = ""; foreach ($result as $results) {     $json = $json . $results; } $obj = json_decode($json);  $Type = $obj->{'Type'};

You can deal with this JSON string in PHP as follows://声明一个json字符串$json = '{ "Type": "ACCREC", "Contact": { "ContactID": "37918a06-92f6-4edb-bfe0-1fc041c90f8b", "Name": "Boom FM", "ContactPersons": [], "Addresses": [], "Phones": [], "ContactGroups": [], "HasAttachments": false, "HasValidationErrors": false }, "LineItems": [], "Date": "2020-04-08", "DueDate": "2020-04-21", "LineAmountTypes": "Exclusive", "InvoiceNumber": "INV-0010", "Reference": "Training", "CurrencyCode": "USD", "Status": "PAID", "SubTotal": 500, "TotalTax": 41.25, "Total": 541.25, "InvoiceID": "4c4db294-3633-45cd-8706-f0b3b0079609", "HasAttachments": false, "IsDiscounted": false, "Payments": [], "Prepayments": [], "Overpayments": [], "AmountDue": 0, "AmountPaid": 0, "FullyPaidOnDate": "2020-04-19", "AmountCredited": 541.25, "UpdatedDateUTC": "2008-12-20T18:38:32+01:00", "CreditNotes": [ { "Date": "2020-04-19", "LineItems": [], "Total": 541.25, "CreditNoteID": "602f5486-664e-492f-b4d1-e12df1d4b8ba", "CreditNoteNumber": "CN-0014", "AppliedAmount": 541.25, "HasAttachments": false, "HasErrors": false } ], "HasErrors": false }'; //1st Way:  // Use json_decode() function to $obj= json_decode($json);$item = $obj->{'Type'};print $item;//2nd way:$obj= json_decode($json,true);$item = $obj['Type'];print $item;
