Phone formatting not working

[GoogleCodeExporter]

Phone formatted fields in Excel 2003 don't show up properly. They output 
something like this: [<=1234567891]1234567891-123456789

I made a fix by passing: format_phone($class_ref->val($row,$col,$sheet))

To this function...

function format_phone($phone) {
    $new_phone = preg_replace("/\[<=(\d{10,})\](\d{10,})-(\d{3,})(\d{3})(\d{4})/", "($3) $4-$5", $phone); //Outputs (###) ###-####

    if($new_phone == $phone || $new_phone == null) {
        return $phone;
    }else{
        return $new_phone;
    }
}
