本文实例为大家分享了php单链表的具体代码，供大家参考，具体内容如下

<?php

/**

 * 单链表

class Demo

{

  private $id;

  public $name;

  public $next;

  public function __construct ($id = '', $name = '')

  {

    $this->id = $id;

    $this->name = $name;

  }

  static public function show ($head)

  {

    $cur = $head;

    while ($cur->next) {

      echo $cur->next->id,'###',$cur->next->name,'<br />';

      $cur = $cur->next;

    }

    echo '<hr />';

  }

  //尾插法

  static public function push ($head, $node)

  {

    $cur = $head;

    while (NULL != $cur->next) {

      $cur = $cur->next;

    }

    $cur->next = $node;

    return $head;

  }

  static public function insert($head, $node)

  {

    $cur = $head;

    while (NULL != $cur->next) {

      if ($cur->next->id > $node->id) {

        break;

      }

      $cur = $cur->next;

    }

    $node->next = $cur->next;

    $cur->next = $node;

    return $head;

  }

  static public function edit($head, $node)

  {

    $cur = $head;

    while (NULL != $cur->next) {

      if ($cur->next->id == $node->id) {

        break;

      }

      $cur = $cur->next;

    }

    $cur->next->name = $node->name;

    return $head;    

  }

  static public function pop ($head, $node)

      if ($cur->next == $node) {

        break;

      }

      $cur = $cur->next;

    }

    $cur->next = $node->next;

    return $head;      

  }

}

$team = new Demo();

$node1 = new Demo(1, '唐三藏');

Demo::push($team, $node1);

$node1->name = '唐僧';

Demo::show($team);

// Demo::show($team);

$node2 = new Demo(2, '孙悟空');

Demo::insert($team, $node2);

// Demo::show($team);

$node3 = new Demo(5, '白龙马');

Demo::push($team, $node3);

// Demo::show($team);

$node4 = new Demo(3, '猪八戒');

Demo::insert($team, $node4);

// Demo::show($team);

$node5 = new Demo(4, '沙和尚');

Demo::insert($team, $node5);

// Demo::show($team);

$node4->name = '猪悟能';//php对象传引用，所以Demo::edit没有必要

// unset($node4);

// $node4 = new Demo(3, '猪悟能');

// Demo::edit($team, $node4);

Demo::pop($team, $node1);

Demo::show($team);

以上就是本文的全部内容，希望对大家实现php单链表有所帮助。
