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."<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;
}
//有序的链表的插入
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 = $cur->next->next;
echo "删除成功<br>";
}
else
{
echo "没有找到<br>";
}
}
static public function updateHero($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 "没有找到<br>";
}
}
}
