Question

开发人员正在向我发送一个多维JSON数组，它有一个我似乎无法从中获取信息的元素/数组。我附上了我的代码和解码数组的片段。

    foreach($item['author'] as $sub){
    if (is_array($sub)){
        foreach($sub as $field => $value){
            if ($field == "name"){
                $author = $value;
            } elseif ($field == "Request"){
                $request = $value;
            } elseif ($field == "Phone"){
                $phone = $value;
....

数组是：

        Array
(
    [0] => Array
        (
            [field] => name
            [value] => John Smith
        )

    [1] => Array
        (
            [field] => Request
            [value] => order
        )

    [2] => Array
        (
            [field] => Phone
            [value] => 123-555-1212
        )
....

我的$ author，$ request和$ phone即将出现。

感谢您提供任何帮助。

Answer 1

字段是一个键，您想检查其中的值

foreach($item['author'] as $sub){
        if (is_array($sub)){
            foreach($sub as $field => $value){
                if ($sub[$field] == "name"){
                    $author = $sub[value];
                } elseif ($sub["$field"] == "Request"){
                    $request = $sub[value];
                } elseif ($sub[$field] == "Phone"){
                    $phone = $sub[$value];
    `

您应该使用$value而不是$field。

$field将是0,1,2（INDEX）等等..

所以解决方案将是：

foreach($a as $field => $value){
       if ($value['field'] == "name"){
            $author = $value['value'];
       }
}

迭代JSON解码数组
