PLEASE HELP been at this for 24hours.... I know its simple because I have done it before... just cant seem to remember of find any referencing code!
推荐答案
您可以在粘贴内容中看到$ results是对象数组，因此您需要指定数组中的哪个项目才能获得正确的电子邮件结果
You can see in what you pasted that $results is an array of objects, so you need to specify which item in the array to get a proper result for email.
示例:
print_r($results[0]->email);
