Hello,
I have an email string that sometimes has a name and the email 
address between <> and sometimes has the email adress right away.

Two examples of the possible value of $address
Joe Doe <[EMAIL PROTECTED]> [EMAIL PROTECTED]
I need to convert this string always to the email address and 
discard the name to the left of the < character, if the string is 
already correct (like [EMAIL PROTECTED]) then do not change 
it, keep it as it is.

I have writen a function to do a for loop and check for the < then 
copy everything to the end removing the >. I wonder, is there a more 
efficient, clear way to accomplish this?

Thanks in advace.

One way to do it (untested):
        $EmailAddress =
        preg_match('/<([^>]+)>/', $TestAddress, $MatchList) ?
        $MatchList[1] :
        $TestAddress
        ;
$TestAddress would be the 'Joe Doe <[EMAIL PROTECTED]>' or 
'[EMAIL PROTECTED]' string, and $EmailAddress *should* be just 
the email address proper. If you want to validate the email address 
further, search the archives for email validation:

See
        http://php.he.net/preg_match
and ternary operators in
        http://us2.php.net/language.operators
for more info.
