Matching uppercase or lowercase string Regex

Question

I need to match the last part an an email and am using Regex.

It is working fine using the following "[a-zA-Z0-9._-][email protected]$" but I want the last part of the address to be upper or lower case.

so that that it will match variations such as

[email protected]
[email protected]
[email protected]

as possible scenarios...so in other words all variations of upper and lower case.

How could I change the pattern to accommodate this

Answer 1

Use the i flag to ignore case.
