Question

例如，我有以下JSON：

    {
    "status": "OK",
    "response": {
        "1": {
            "name": "Personal Information",
            "fields": {
                "1": {
                    "name": "About Me",
                    "value": ""
                },
                "4": {
                    "name": "Discord name",
                    "value": "TestAccount#1012"
                }
            }
        }
    }
}

例如，我是否有机会搜索 Discord名称，并得到 TestAccount＃1012 ？

因为ID号码或称为ID的号码有时会“可能”更改。（我正在尝试一种更简单的方法来阅读我的论坛rest api）

更新：这是我当前的代码：

<?php {
if ( $_GET ) //Make sure it is a post request.
{
    if ( isset( $_GET[ "forum" ] ) && isset( $_GET[ "api" ] ) && isset( $_GET[ "username" ] ) ) //Make sure username and serial are provided.
    {
        $communityUrl = $_GET[ "forum" ];
        $apiKey = $_GET[ "api" ];


        $curl = curl_init( $communityUrl . 'api/index.php?/core/members&name=' . $_GET[ "username" ] );
        curl_setopt_array( $curl, array(
            CURLOPT_RETURNTRANSFER => TRUE,
            CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
            CURLOPT_USERPWD => "{$apiKey}:"
        ) );
        $response = curl_exec( $curl );
        header( 'Content-Type: application/json' );
        if ( $response === false ) {
            // Website down so result is this
            $jsonanswer = array(
                "status" => 'FAILED',
                "response" => 'Test1'
            );
            echo json_encode( $jsonanswer, JSON_PRETTY_PRINT );
        } else {
            $requestjson = json_decode( $response, true );
            $checkuser = $requestjson[ 'results' ];
            switch ( json_last_error() ) {
                case JSON_ERROR_NONE:
                    // Check if there is a member
                    if ( empty( $checkuser ) ) {
                        $jsonanswer = array(
                            "status" => 'NOTFOUND',
                            "response" => 'Test2'

                    } else {
                        $jsonanswer = array(
                                    "status" => 'OK',
                                    "response" => $requestjson[ 'results' ][ 0 ][ 'customFields' ]
                                );
                                echo json_encode( $jsonanswer, JSON_PRETTY_PRINT );

                    }

                    echo json_encode( $jsonanswer, JSON_PRETTY_PRINT );
                    break;
                case JSON_ERROR_STATE_MISMATCH:
                    // Underflow or the modes mismatch
                    $jsonanswer = array(

                case JSON_ERROR_CTRL_CHAR:
                    // Unexpected control character found
                    $jsonanswer = array(
                        "status" => 'FAILED',
                        "response" => 'Test 5'
                    );
                    echo json_encode( $jsonanswer, JSON_PRETTY_PRINT );
                    break;
                case JSON_ERROR_SYNTAX:

                    $jsonanswer = array(

                        "response" => 'Test 6'
                    );
                    echo json_encode( $jsonanswer, JSON_PRETTY_PRINT );
                    break;
                case JSON_ERROR_UTF8:

                    $jsonanswer = array(
                        "status" => 'FAILED',
                        "response" => 'Test 7'
                    );
                    echo json_encode( $jsonanswer, JSON_PRETTY_PRINT );
                    break;
                default:
                    // Unknown error
                    $jsonanswer = array(
                        "status" => 'FAILED',
                        "response" => 'Test 8'

                    echo json_encode( $jsonanswer, JSON_PRETTY_PRINT );
                    break;
            }
        }
    } else {
        die( "Access Denied!" ); //Not a post request. Display Access Denied and exit.
    }

} else {
    die( "Access Denied!" ); //Not a post request. Display Access Denied and exit.
}

}

当前，我正在请求自定义字段，但是在我不知道如何过滤后，如果我搜索 Discord名称，就会得到该值。

Answer 1

如果name的值是唯一的，这是一种有趣的方式：

$name = 'Discord name';

echo array_column(current(json_decode($json, true)['response'])['fields'],
                  'value', 'name')[$name];

如果您已经解码了JSON：

echo array_column(current($array['response'])['fields'], 'value', 'name')[$name];

这是使用name作为键并以value作为值来提取新数组，并访问键$name。

搜索值并获取其他值
