Question

我在ubuntu 16.04上使用Laravel 5.3，当我运行此代码时：

    echo "<pre>";
    print_r($currentSessions[0]);
    echo "</pre>";

    echo "<pre>";
    print_r($lmirOrder);
    echo "</pre>";

返回：

$ currentSessions [0]是：

stdClass Object
(
[iID] => 484444768
[bStatus] => SESSION_ONHOLDBUTCUSTOMERLEFT
[sStatus] => Closed by waiting customer
[iEntry] => 404466296
[sEntry] => Technical Support
[iTechnician] => 17536581
[sTechnician] => Removed
[sStartTime] => 11/23/2016 2:48:35 PM
[iWaitingTimeInSec] => 2 Hours
[sCustomField0] => removed
[sCustomField1] => removed
[sCustomField2] => Array
    (
        [phoneNumber] => removed
        [emailAddress] => removed
    )

[sCustomField3] => 
[sCustomField4] => 
[sCustomField5] => 
[sLanguage] => en
[sTransferredTo] => 
[sTransferredComment] => 
[bIsLead] => 1
[bHandingOff] => 
)

$ lmirOrder是：

Array
(
[1] => sTechnician
[2] => sCustomField0
[3] => sCustomField2[phoneNumber]
[4] => sStatus
[5] => sStartTime
[6] => sCustomField1
[7] => iWaitingTimeInSec
[8] => sCustomField2[emailAddress]
)

当我回显时，为什么会出现“数组到字符串转换”错误：

echo $currentSessions[0]->$lmirOrder[4];

非常感谢任何帮助！

这是因为声明$currentSessions[0]->$lmirOrder[4]实际上被解释为{$currentSessions[0]->$lmirOrder}[4]导致在对象上查找属性Array。

<?php

$a = new stdClass();
$a->test = 'Hello World';
$a->Array = "You didn't want me";

$b = ['test'];

// Notice: Array to string conversion in php shell code on line 6
// string(1) "Y"
var_dump($a->$b[0]); 

// string(11) "Hello World"
var_dump($a->{$b[0]});

Laravel给了我数组到字符串的转换错误，我做错了什么？
