内部数组json_en code变量 [英] json_encode variable inside array

问题描述

我使用json_en code创建从我想静态数组里面放置一个foreach的数组。我已经加载了json_en codeD数组变量。如果我附和变量，数据看起来不错。这只是当我输入变量放入数组，这是行不通的。

I am using json_encode to create an array from a foreach that I would like to place inside of a static array. I have loaded the json_encoded array into a variable. If I echo the variable, the data looks great. It's just when I enter the variable into the array, it doesn't work.

这是我的foreach。

This is my foreach.

$arr = array();
foreach ($response->records as $record) {
    $r['id'] = $record->Id;
    $r['title'] = $record->Title;
    $r['pin'] = $record->Pin;

$arr[] = $r;

}

$locations = json_encode($arr);

这是我的，我已经进入了$位置静态数组变量。

And this is my static array where I have entered the $locations variable.

$data = array(
    'name' => Locations,
    'data' => '{
        "title":"USA",
        "location":"World",
        "levels":[
            {
                "id":"states",
                "title":"States",
                "locations":'$locations'
            }
        ]
    }'
);

这它，我看到的错误。

Parse error: syntax error, unexpected '$locations' (T_VARIABLE), expecting ')'

我想AP preciate的帮助，谢谢。

I would appreciate the help, thank you.

您正在寻找的小玩意儿是的连接符它看起来像这样

The gizmo you're looking for is the concatenation operator which looks like this

据胶合串在一起。

It glues strings together.

$data = array(
    'name' => Locations,
    'data' => '{
        "title":"USA",
        "location":"World",
        "levels":[
            {
                "id":"states",
                "title":"States",
                "locations":' . $locations . '
            }
        ]
    }'
);
