Try casting the value and comparing it with the original one:

define('DECIMAL_SEPARATOR', '.');

switch ($fieldList[$i])
{
    case (string)(int)$fieldList[$i]:
        $typeInfo = (strpos($fieldList[$i], DECIMAL_SEPARATOR) === false) ? 'int(11)' : 'float';
        break;
    case (string)(float)$fieldList[$i]:
        $typeInfo = 'float';
        break;
    default:
        $typeInfo = 'varchar(80)';
        break;
}

Additionaly, check for the presence of decimal separator in the first case for numbers that are round, yet they have the decimal fraction part.
