Please help: function to prevent numbers and @ signs in text field

[php-newbies]

Hi all, I have a textarea field name brief in my php form. The problem is that users are entering phone numbers and email addresses in this field even though there is dedicated email and phone fields. I want a function to either delete the numbers and emails address automatically on this field or alert the user that numbers are not allowed in this field.

 

I have include my form.

 

Many thanks for your help
