用于字母的PHP正则表达式后跟数字后跟“hotmail.com”

Question

I have a very specific requirement to stop bots attacking my site. They are joining and registering with email addresses of the form:

[first_name][numbers]@hotmail.com

e.g. [e-mail]

Can someone please give me the regex to match this so I can block them at registration?

Answer 1

Try this -

^[a-zA-Z]+[0-9]+@hotmail\.com$
