PHP根据URL提取主域名,在网上荡了一个!

优化了一下域名库,修复了PHP7.0!

可以直接拿来用,测试了一下没发现问题!

<?php  #使用示例 echo getBaseDomain('http://blog.jp.goo.ne.jp/index.php','domain');echo "\n"; echo getBaseDomain('http://51.ca/index.php','domain');echo "\n"; echo getBaseDomain('https://blog.ab.cc.win.aisa.hk/index.php','domain');echo "\n";   
   function getBaseDomain($url='',$type){   if(!$url){     return $url[$type];   }   #列举域名中固定元素   $state_domain = array(     'al','dz','af','ar','ae','aw','om','az','eg','et','ie','ee','ad','ao','ai','ag','at','au','mo','bb','pg','bs','pk','py','ps','bh','pa','br','by','bm','bg','mp','bj','be','is','pr','ba','pl','bo','bz','bw','bt','bf','bi','bv','kp','gq','dk','de','tl','tp','tg','dm','do','ru','ec','er','fr','fo','pf','gf','tf','va','ph','fj','fi','cv','fk','gm','cg','cd','co','cr','gg','gd','gl','ge','cu','gp','gu','gy','kz','ht','kr','nl','an','hm','hn','ki','dj','kg','gn','gw','ca','gh','ga','kh','cz','zw','cm','qa','ky','km','ci','kw','cc','hr','ke','ck','lv','ls','la','lb','lt','lr','ly','li','re','lu','rw','ro','mg','im','mv','mt','mw','my','ml','mk','mh','mq','yt','mu','mr','us','um','as','vi','mn','ms','bd','pe','fm','mm','md','ma','mc','mz','mx','nr','np','ni','ne','ng','nu','no','nf','na','za','aq','gs','eu','pw','pn','pt','jp','se','ch','sv','ws','yu','sl','sn','cy','sc','sa','cx','st','sh','kn','lc','sm','pm','vc','lk','sk','si','sj','sz','sd','sr','sb','so','tj','tw','th','tz','to','tc','tt','tn','tv','tr','tm','tk','wf','vu','gt','ve','bn','ug','ua','uy','uz','es','eh','gr','hk','sg','nc','nz','hu','sy','jm','am','ac','ye','iq','ir','il','it','in','id','uk','vg','io','jo','vn','zm','je','td','gi','cl','cf','cn','yr','com','arpa','edu','gov','int','mil','net','org','biz','info','pro','name','museum','coop','aero','xxx','idv','me','mobi','asia','ax','bl','bq','cat','cw','gb','jobs','mf','rs','su','sx','tel','travel','accountant','app','art','auction','audio','auto','band','bar','beer','best','bid','bike','black','blog','blue','business','cab','cafe','camera','car','cards','cars','cash','center','ceo','chat','city','click','clothing','club','cn.com','coffee','com.co','com.hk','com.tw','company','cool','credit','cricket','date','design','dev','diet','dog','domains','download','email','equipment','estate','expert','faith','family','fans','feedback','fish','fit','flowers','fun','fund','fyi','game','games','gift','gives','gold','group','guru','haus','help','holiday','host','hosting','house','ink','kim','land','life','link','live','loan','lol','love','ltd','market','marketing','mba','media','men','mom','money','net.co','network','news','one','online','ooo','party','pet','photo','photography','photos','pics','pink','plus','press','property','pub','racing','red','ren','rent','review','rip','run','sale','school','science','services','sex','sexy','shop','show','site','social','software','solutions','space','store','studio','style','support','taipei','tax','team','tech','test','tips','today','tools','top','town','toys','trade','ventures','vet','video','vin','vip','wang','watch','webcam','website','wiki','win','wine','work','works','world','wtf','xin','xyz','yoga','zone','net.cn','org.cn'   );
