Question

我正在使用curl和php从api检索数据。我能够从api成功获取响应并从中检索所需的数据。每当我尝试将数据传递到数组以能够将其返回时，都会出现我的问题，因为当我在数组上使用var_dump（）时，它为空。任何有关如何使该数组返回其值的指针都很好

// decode json string into array
$output = json_decode($output, true);

// check if the supplied data is an array
if(is_array($output)){
//loop through the first level of the array
foreach($output as $key => $value) {
   //assigning variable values

    $btcDominance = ["btc_dominance"];
   $errorMsg = $value["error_message"];
$errorCode = $value["error_code"];
$timestamp = $value["last_updated"];





//check if the next level is an array and loop through it
if(is_array($value)) {
foreach($value as $key => $values) {


//check if the next level is an array and loop through it
    if(is_array($values)) {
    foreach($values as $keys => $value3) {
    //check if the next level is an array and loop through it

        $marketCap = $value3["total_market_cap"];
        $volume = $value3["total_volume_24h"];





$values = array('btc' => $btcDominance,
'errMsg' => $errorMsg);
return $values;


}//foreach3

}//isarray 3        

}//foreach2

}//is array 2       

}//foreach1
}//is array 1



}//end of qryCmc

我认为getValues函数可能是数组返回为空白的原因，但是如果我从该函数中删除“ =”“，则会收到警告：Cmc :: getValues（）的参数1缺失

function getValues($values ='') {
return $this->output;
}
}// end of Cmc



  $cmc = new Cmc();
  var_dump($cmc->getValues());

填充的数组返回空白
