看了很久數(shù)據(jù)結(jié)構(gòu)但是沒有怎么用過，在網(wǎng)上看到了關(guān)于php的數(shù)據(jù)結(jié)構(gòu)，學(xué)習(xí)了一下，與大家一起分享一下。

代碼如下:

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(chuàng)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);

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。
