foreach只获得第一个值，而不是循环
$all =TwitchApi::streams($options);
foreach ($all['streams'] as $streams){
$stream = new streams;
$stream->stream_id = $streams['channel']['_id'];
$stream->game = $streams['channel']['game'];
$stream->service = 'twitch';
$stream->viewers =$streams['channel']['views'];
//$stream->save();
var_dump($all['streams']);
}
当我变换转储（$ all [＆＃39; streams＆＃39;]）时，我得到了这个：

在这个循环后我有一个返回但它没有任何区别，因为我在到达return语句之前转储数据 什么错了？
答案 0 :(得分：0)
您在foreach循环$streams中命名了第二个变量，而在循环体中引用了$stream。
答案 1 :(得分：0)
试试这个;
$all =TwitchApi::streams($options);
$all = json_encode($all);
function objectToArray( $object )
{
if( !is_object( $object ) && !is_array( $object ) )
{
return $object;
}
if( is_object( $object ) )
{
$object = get_object_vars( $object );
}
return array_map( 'objectToArray', $object );
}
$depth = 512;
$options = 1;
$result = json_decode ($json, $assoc, $depth, $options);
$result = objectToArray($result);
var_dump($result["_total"]);
首先将all转换为JSON，然后将其转换为Array，然后从数组中获取值。
答案 2 :(得分：0)
这里是答案人：）
$all =TwitchApi::streams($options);
$clean[] = $all['streams'];
//dd($clean['0']['1']['game']);
for ($idx = 0; $idx < 100; $idx++){
//print_r($idx);
$stream = new streams;
$stream->stream_id = $clean['0'][$idx]['channel']['_id'];
$stream->game = $clean['0'][$idx]['channel']['game'];
$stream->service = 'twitch';
$stream->viewers =$clean['0'][$idx]['channel']['views'];
$stream->save();
}
