PHP iAddressBook is an address book for a single user. You can use it for Personal or Business Cards (it supports tons of fields), features a spotlight-like search, has transparent vCard import/export, multilanguage support, design templates and an intuitive interface. It aims at 100% compatibility to the AddressBook in macOS.
