I like Egil's idea of readable code using explode and regular
expressions. Or, you could use this function I wrote:
function isValidEmail($email) {
if(strlen($email) < 6)
return false;
$at = -1; // index of '@'
for($i=0; $i<strlen($email); $i++) {
if($email[$i] == '@')
$at = $i;
}
if($at < 1)
return false;
for($i=$at; $i<strlen($email); $i++) {
if($email[$i] == '.')
break;
}
if($i>$at && $i<strlen($email))
return true;
else
return false;
}

Brush up on your patternmatching then, brother. Check the php.net manual
on regexp.
If you want more readable code, try splitting the string (explode) on @
first, then split the segment after @ that you now have on . again.
Cheers,
Egil (in Norway, so I am way past bedtime myself :))
