错误 - {时间} - ＆gt;严重性：警告 - ＆gt; array_values（）期望参数1是数组，对象给出instagram_helper.php 169

Question

在我的codeigniter脚本日志中，我看到了这个错误：

  

ERROR - 2018-02-12 03:54:11 - ＆gt;严重性：警告 - ＆gt; array_values（）期望参数1为数组，给定对象/home/webhouse/public_html/app/helpers/instagram_helper.php 169

instagram_helper.php第169行：

return array_values($feeds);

这是instagram_helper.php php代码：

function instacurl(){
    if(FX == 1){
        return false;
    }else{
        return true;
    }
}

function file_get_contents_curl($url) {
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    $data = curl_exec($ch);
    curl_close($ch);

    return $data;
}

任何想法？
