For more information of public suffixes, and why you may want to query the list, please see [publicsuffix.org](https://publicsuffix.org/) Installation ============ [](#installation) > composer require xoops/regdom Usage ===== [](#usage) Class Xoops\\RegDom\\PublicSuffixList ------------------------------------- [](#class-xoopsregdompublicsuffixlist) This class handles all direct interaction with the public suffix list (PSL.) This includes, fetching the list from a source URL, caching that list locally, converting that list to a tree form to facilitate rapid lookup, and caching that tree in a serialized form. ### $psl = new PublicSuffixList(*$url*) [](#psl--new-publicsuffixlisturl) Creates a new PublicSuffixList object that will use the specified URL as the source of the PSL. If no *$url* is specified, it will default to [https://publicsuffix.org/list/public\_suffix\_list.dat](https://publicsuffix.org/list/public_suffix_list.dat) ### $psl->setURL(*$url*) [](#psl-seturlurl) Resets the current PSL, and uses the specified URL as the source. ### $psl->getTree() [](#psl-gettree) Returns the tree of the current PSL. `Xoops\RegDom\RegisteredDomain`uses this tree form for all lookups. ### $psl->clearDataDirectory(*$cacheOnly*) [](#psl-cleardatadirectorycacheonly) By default, this will clear all cached PSL data, including local copies of remotely accessed PSL data. Pass *true* for `$cacheOnly` to clear only the serialized tree data. Class Xoops\\RegDom\\RegisteredDomain ------------------------------------- [](#class-xoopsregdomregistereddomain) This class can be used to determine the registrable domain portion of a URL, respecting the public suffix list conventions. ### $regdom = new RegisteredDomain(PublicSuffixList *$psl*) [](#regdom--new-registereddomainpublicsuffixlist-psl) Creates a new RegisteredDomain object that will use *$psl* to access the PSL. If no *$psl* is specified, a new PublicSuffixList object will be instantiated using default behaviors. ### $regdom->getRegisteredDomain(*$host*) [](#regdom-getregistereddomainhost) Returns the shortest registrable domain portion of the supplied *$host*, or *null* if the host could not be validly registered. Examples: `echo $regdom->getRegisteredDomain('https://www.google.com/');`Outputs: > google.com `echo $regdom->getRegisteredDomain('theregister.co.uk');`Outputs: > theregister.co.uk `echo null === $regdom->getRegisteredDomain('co.uk');`Outputs: > 1 script bin\\reloadpsl --------------------- [](#script-binreloadpsl) This script can be used to load a fresh copy of the PSL. It may be useful in cron job, or other scripted updates.
