I have added PHP YAZ as extension into XAMPP following steps in the latest comment here http://php.net/manual/en/ref.yaz.php but when I check for YAZ section in PHPINFO, I do not have YAZ section there. Can somebody try to install it check if it is only my problem or there is something wrong?
So after all installation tutorials, it appears that even though the extension can be enabled just by adding DLL file into ext folder but it is necessary to add other DLL files, except php_*.dll where * is name of the extension, into apache\bin\ folder. Then restart server and in phpinfo you should have new extension section.
