PHP实现链表
看了很久數據結構但是沒有怎么用過,在網上看到了關于PHP的數據結構,學習了一下,與大家一起分享一下。
簡短不割?????????????????????????????????????????????????????????????????????????????????????
class Hero {public $no;//排名public $name;//名字public $next=null;//$next是一個引用,指向另外一個Hero的對象實例public function __construct($no='',$name=''){$this->no=$no;$this->name=$name;}static public function showList($head){$cur = $head;while($cur->next!=null){echo "排名:".$cur->next->no.",名字:".$cur->next->name."<br>";$cur = $cur->next;}} //普通插入static public function addHero($head,$hero){$cur = $head;while($cur->next!=null){$cur = $cur->next;}$cur->next=$hero;}//有序的鏈表的插入 static public function addHeroSorted($head,$hero){$cur = $head;$addNo = $hero->no;while($cur->next->no <= $addNo){$cur = $cur->next;}/*$tep = new Hero();$tep = $cur->next;$cur->next = $hero;$hero->next =$tep;*/$hero->next=$cur->next;$cur->next=$hero;}static public function deleteHero($head,$no){$cur = $head;while($cur->next->no != $no && $cur->next!= null){$cur = $cur->next;}if($cur->next->no != null){$cur->next = $cur->next->next;echo "刪除成功<br>"; }else{echo "沒有找到<br>"; }}static public function updateHero($head,$hero){$cur = $head;while($cur->next->no != $hero->no && $cur->next!= null){$cur = $cur->next;}if($cur->next->no != null){$hero->next = $cur->next->next;$cur->next = $hero;echo "更改成功<br>"; }else{echo "沒有找到<br>"; }} }//創建head頭 $head = new Hero(); //第一個 $hero = new Hero(1,'111'); //連接 $head->next = $hero; //第二個 $hero2 = new Hero(3,'333'); //連接 Hero::addHero($head,$hero2); $hero3 = new Hero(2,'222'); Hero::addHeroSorted($head,$hero3); //顯示 Hero::showlist($head); //刪除 Hero::deleteHero($head,4); //顯示 Hero::showlist($head); //更改 $hero4=new Hero(2,'xxx'); Hero::updateHero($head,$hero4); //顯示 Hero::showlist($head);我是天王蓋地虎的分割線????????????????????????????????????????????????????????????????
有序的插入的話需要遍歷一遍鏈表,鏈表的一些知識就不介紹了哈。這里主要分享一下代碼。
