An example of a `ctype_*` function uage in the Magento 2.0.x branch

magento/magento2/blob/2.0.0/app/code/Magento/CatalogImportExport/Model/Import/Product/Option.php#L782-L797


      
          /**
           * Validation of additional data in main row
           *
           * @param array $rowData
           * @param int $rowNumber
           * @return bool
           */
          protected function _validateMainRowAdditionalData(array $rowData, $rowNumber)
          {
              if (!empty($rowData[self::COLUMN_SORT_ORDER]) && !ctype_digit((string)$rowData[self::COLUMN_SORT_ORDER])) {
                  $this->_productEntity->addRowError(self::ERROR_INVALID_SORT_ORDER, $rowNumber);
              } else {
                  return true;
              }
              return false;
          }

But the official system requirements document for Magento 2.0.x does not methion it:

Magento 2 does document its dependence on the `ctype` PHP extension

http://devdocs.magento.com/guides/v2.2/install-gde/system-requirements-tech.html#required-php-extensions

The `ctype` PHP extension is not ebabled by default in some Unix-like systems (e.g., FreeBSD)

http://php.net/manual/en/ctype.installation.php#119977

On FreeBSD, this library is NOT included automatically.
It must be manually installed.
This can be done with the following command:
pkg install php70-ctype
