php preg_match, how to switch values

Question

Hello guys.

Please help with this little issue if you could.

I would like to search a string, if a match is made, I'd like to change the value to something else.

eg.

if (preg_match("gmail",$email)) {

// code needed to switch "gmail" for "googlemail"

}

This is needed because my mail server won't accept an email address in 'gmail.com' format.

Thanks in advance. Shane

Answer 1

Use preg_replace:

preg_replace("gmail", "googlemail", $email);

Answer 2

if you don't need regular expressions just use str_replace. No need to test either, just replace it.

str_replace( '@gmail.com', '@googlemail.com', $email );

Answer 3

Just so it doesn't match something like [email protected]:

$email = preg_replace('/(.+)gmail(\..+)$/', '$1googlemail$2', $email);
