看了很久数据结构但是没有怎么用过,在网上看到了关于PHP的数据结构,学习了一下,与大家一起分享一下。

复制代码 代码如下:
class Hero
{
    public $no;//排名
    public $name;//名字
    public $next=null;//$next是一个引用,指向另外一个Hero的对象实例

    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."
";
            $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;
    }
    //有序的链表的插入 
    static public function addHeroSorted($head,$hero)
    {
        $cur = $head;
        $addNo = $hero->no;
        while($cur->next->no         {
            $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 "删除成功
";
        }
        else
        {
            echo "没有找到
";
        }
    }

    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
";
        }
        else
        {
            echo "没有找到
";
        }
    }
}

//创建head头
$head = new Hero();
//第一个
$hero = new Hero(1,'111');
//连接
$head->next = $hero;
//第二个
$hero2 = new Hero(3,'333');
//连接
Hero::addHero($head,$hero2);
$hero3 = new Hero(2,'222');
Hero::addHeroSorted($head,$hero3);
//显示
Hero::showlist($head);
//删除
Hero::deleteHero($head,4);
//显示
Hero::showlist($head);
//更改
$hero4=new Hero(2,'xxx');
Hero::updateHero($head,$hero4);
//显示
Hero::showlist($head);

有序的插入的话需要遍历一遍链表,链表的一些知识就不介绍了哈。这里主要分享一下代码。
