PHP message matching

There is an information template, such as:
"Name: @, phone number @, please notify this person"
The @ is a variable that needs to be modified, fill in the information, and become

<code>"姓名:小明,电话:15888888888,请通知此人"
</code>

How can I tell whether the modified template uses the previous template?

Regular replacement preg_replace :xxx, Replace with:@,

<code>$a = "姓名:小明,电话:15888888888,请通知此人";
var_dump(preg_replace('/:([^<]*?),/is',':@,',$a));</code>

Then compare it with your message template.
