/** Get configuration and whitelist data */

/** Object initialization */

/** Set parameter */
$streetNameKga->setTypeWhitelist($streetTypeList);
$streetNameKga->setDistrictWhitelist($districtWhitelist);
$streetNameKga->setStreetNormalization($streetNormalizedList);
$streetNameKga->setPatternStreetName($patternStreetName);

/** Get a result (array) with normalized data */
$data = $streetNameKga->getCsvAsArray($pathSourceFile);

/** Get other data */
$res = [];
$res['type_list'] = $streetNameKga->getTypeList();
$res['type_counter'] = $streetNameKga->getTypeCounter();
$res['name_list'] = $streetNameKga->getNameList();
$res['name_double'] = $streetNameKga->getNameDouble();
$res['district_not_whitelist'] = $streetNameKga->getDistrictNotFound();

/** Get warnings if present */
$warning = $streetNameKga->getWarning();
$warningValue = $streetNameKga->getWarningValue();
if (null !== $warning AND count($warning) > 0) {
    print_r($warning);
}
print_r($data);
print_r($res);

Ukrainian language

Apostrophe

The resulting data will contain as ukrainian apostrophe symbol "ʼ" unicode symbol U+02BC. All other similar characters in source data (' - U+0027, ’ - U+2019, etc) will be replaced to ʼ (U+02BC). U+02BC - this symbol is used in the ukrainian domain name (ICANN).
