What will be the output of the following PHP code?

Home » PHP » PHP Strings » Question

$name = "mAnjeSh";
if (ereg("([^a-z])",$name))
echo "Name must be all lowercase!";
else
echo "Name is all lowercase!";
?>

1. Name is all lowercase!
2. No Output is returned
3. Name must be all lowercase!
4. Error
5. None of these

Correct Option: C

Because the provided name is not all lowercase, ereg() will not return FALSE (instead returning the length of the matched string, which PHP will treat as TRUE), causing the message to output.
