For the following two things:
对于以下两件事：
$value['id']
$value['std']
the variable $valueis not an array but a string. And the square brackets then are substring access. Because the string is empty, you get the error message.
变量$value不是数组而是字符串。然后方括号是子串访问。由于字符串为空，您会收到错误消息。

The [] binds stronger than the $$, i.e. php first evaluates $value['id']and then would use this value as the name/identifier for the variable variable.
Use curly braces to change the precedence.
[] 绑定比 $$ 强，即 php 首先评估$value['id']，然后将此值用作变量变量的名称/标识符。
使用花括号更改优先级。
<?php
$array = array('id'=>123);
$value = 'array';
echo ${$value}['id'];
prints 123.
打印123。

Its hard to say unless we know the pattern that $optionshold.
Try
除非我们知道其中的模式，否则很难说$options。尝试
$value->idinstead of $value["id"]
$value->id代替 $value["id"]
