Until now, I have been validating the ID with the following regex:
到目前为止,我一直在使用以下正则表达式验证ID:
's_id' => 'unique:users|required|max:255|regex:/^\d{3}\-\d{2}\-\d{3}$/'
It validates the ID in the ***-**-*** format.
它以*** - ** - ***格式验证ID。
How can I validate the students id having the initial of 131-35-*** only?
如何验证初始值为131-35的学生ID?***?

Since \d{3} matches any three digits and \d{2} matches any two digits, your current regex just matches any first 5 digits.
由于\ d {3}匹配任意三位数且\ d {2}匹配任意两位数,因此您当前的正则表达式只匹配前5位数。
If the digits are set, known beforehand, they can be "hard-coded" into the pattern.
如果预先知道了数字,则可以将它们“硬编码”到模式中。
Use
regex:/^131-35-\d{3}$/
Now, only the last 3 digits can be any digits from 0 to 9.
现在,只有最后3位数字可以是0到9之间的任何数字。
