Regex to match email (not strict)

Question

I would like to validate if an email address is entered by the user but I don't want to be too strict on it... So I came up with this....

My current if statement with regex:

if (preg_match('^/.+?@.+?\..+$/', $_POST["email"]))

However, I would not work for an email address with multiple periods...

For example:

testing@test.one.com

How can I allow multiple . or periods?

You can allow any character multiple times by putting the `+` character after them // `a` = `1 "a" character` // `a*` = `0 or more "a" characters` // `a+` = `1 or more "a" characters` // `a{2,5}` = `2 to 5 "a" characters` — h2ooooooo, Feb 05 '15 at 18:09

I would suggest something far simpler that doesn't require you to reinvent the wheel

if(filter_var($_POST["email"], FILTER_VALIDATE_EMAIL))
