创建Laravel数组

问题描述：

I'm trying to create an array with Laravel but customise some of the values.

For example, if I was to return $user->rounds this would return

"data": [
    {
        "id": 3,
        "name": "sample name"
    },
    {
        "id": 4,
        "name": "sample name 2"
    }
]

I want to customise the return to something like

"data": [
    {
        "id": 3,
        "name": "sample name",
        "extra": "Extra Detail"
    },
    {
        "id": 4,
        "name": "sample name 2",
        "extra": "Extra Detail"
    }
]

I'm trying to do it, by the following code:

$data = array();

foreach ($user->rounds as $r) {
    $data = [
        'id' => $r->id,
        'name' => $r->name,
        'extra' => 'Test Extra'
    ];
}

return $data;

But it returns only one round while it should be returning 3.

我正在尝试使用Laravel创建一个数组但是自定义了一些值。 p> \ n

例如，如果我要返回$ user-＆gt; rounds code>，则返回 p>

 “data”：[
 {  
“id”：3，
“名称”：“样本名称”
}，
 {
“id”：4，
“名称”：“样本名称2”
} 
]  
  code>  pre> 
 
 我想将返回自定义为 p> 
 
 
 “data”：[
 {
  “id”：3，
“名称”：“示例名称”，
“额外”：“额外详细信息”
}，
 {
“id”：4，
“名称”：“示例 名称2“，
”额外“：”额外细节“
} 
] 
  code>  pre> 
 
 我正在尝试通过以下代码执行此操作：   p> 
 
 
  $ data = array（）; 
 
foreach（$ user-＆gt; rounds as $ r）{
 $ data = [
'id'=＆gt;  ;  $ r-＆gt; id，
'name'=＆gt;  $ r-＆gt; name，
'extra'=＆gt;  '测试额外'
]; 
} 
 
返回$ data; 
  code>  pre> 
 
 但它只返回一轮，而它应该返回3。  p> 
  div>

答

You need to add array to $data array with each iteration:

$data[] = [
    'id' => $r->id,
    'name' => $r->name,
    'extra' => 'Test Extra'
];

Also, you could use array_push() function for that.

Try to do like this

$data = array();
$i=0;
foreach($user->rounds as $r){
  $data[$i] = [
    'id' => $r->id,
    'name' => $r->name,
    'extra' => 'Test Extra'
  ];
  $i++;
}
return $data;
