There are two arrays, namely

<code>$template1 = array(
            "您好,你的网址是@,请访问",
            "您预约的时间在@,请按时到@报道",
            "您的面试一结束,请给@评价吧,网址在@"
)
$template2 = array(
            "你的验证码是@",
            "所有的特殊字符有@"
)
</code>
Copy after login
Copy after login

The @ is any possible string, now if I get a string

<code>$message = "您好,你的网址是http://www.baidu.com/jsdkj,请访问";</code>
Copy after login
Copy after login

How to determine which array this $message belongs to?

Convert the string in the template into a regular expression, and then match the messages one by one.

For example:

<code>$template1 = array(
            "您好,你的网址是.*,请访问",
            "您预约的时间在.*,请按时到.*报道",
            "您的面试一结束,请给.*评价吧,网址在.*"
)
</code>

It is worth noting: If the template array is relatively large, it may affect performance. Also, template rendering is usually supposed to be one-way, so I doubt the legitimacy of this requirement.

Can’t it be done with just one in_array? Could it be that I misunderstood what the poster meant?

Just judge strpos in the form of keywords

This kind of logic is too rare. Usually, the message is obtained based on variable + template, and you do not need to infer based on the message. Is there something wrong in your understanding?
