php表单从mysql变量中选择选项数组

Hopefully a simple one.

I am using a drop down on a form as follows:

// A sample product array
$products = array("Mobile", "Laptop", "Tablet", "Camera");

this works fine but rather than define the list I was hoping to populate the options using a variable populated from Mysql, Here is what I have

// A sample product array
$products = array<?php echo $customoption1data;>;

But I can't seem to get it to work.

The data in the table is formatted as "Mobile", "Laptop", "Tablet", "Camera"

Where am I going wrong?
