你好

我偶然发现了一个简单的问题，但我不知道可能出了什么问题：

        function zabbixGraphGetId($HostName, $Name,$zabbixData) {

            try {

                $api = new ZabbixApi(...$zabbixData);

            } catch (Exception $e) {
                // Exception in ZabbixApi catched
                echo $e->getMessage();
            }
            $GetGraphId = $api->graphGet(array(
                'output' => 'extend',
                'filter' => array('host' => $HostName),
                'search' => array('name' => $Name)
            ));
            $ReturnGraphId = $GetGraphId['0']->graphid;

            return $ReturnGraphId;
        }

那是我在 symfony 中的函数，我想从数组 $GetGraphId 中获取只有 graphid 的值。关键是在我调用这个函数之后我得到这个错误：警告：尝试读取数组上的属性“graphid”但是如果我返回整个数组（$GetGraphId）我得到这个：

array:2 [
  0 => array:19 [
    "graphid" => "some id"
    "name" => "Network traffic on tun0"
    "width" => "900"
    "height" => "200"
    "yaxismin" => "0"
    "yaxismax" => "100"
    "templateid" => "0"
    "show_work_period" => "1"
    "show_triggers" => "1"
    "graphtype" => "0"
    "show_legend" => "1"
    "show_3d" => "0"
    "percent_left" => "0"
    "percent_right" => "0"
    "ymin_type" => "1"
    "ymax_type" => "0"
    "ymin_itemid" => "0"
    "ymax_itemid" => "0"
    "flags" => "4"
  ]

所以有graphid值但我仍然无法得到它，我真的很感激任何线索/想法/解决方案谢谢！

警告说：尝试读取数组上的属性“graphid”。您不能使用object->property表示法访问 graphid。请改用此行：

$ReturnGraphId = $GetGraphId['0']['graphid'];
