PHP中模拟链表和链表的基本操作示例

模拟链表：

name = $name;
    $this->id  = $id;
  }
   
  
  public static function echo_link_list($head) {
    $curr = $head;
    while ($curr->next != null) {
      echo '姓名:'.$curr->next->name, ' 编号:'.$curr->next->id;
      echo '
';
      $curr = $curr->next;
    }
  }
   
  
  public static function add($head, $id, $name) {
    $curr = $head;
    $obj = new linkList($id, $name);
     
    while ($curr->next != null) {
      // 如果当前ID < 下一个ID,则添加到中间，添加节点到指定顺序位置
      if ($curr->next->id > $id) {
  
 $obj->next = $curr->next;
 $curr->next = $obj;
  
 return true;
      } else if ($curr->next->id == $id) {
  
 echo '当前Id:'.$id.'重复了，请不要继续添加了！';
 echo '
';
  
 return false;
      }
      $curr = $curr->next;
    }
    // 添加节点到尾部
    if ($curr->next == null) {
      $curr->next = $obj;
    }
  }
   
  
  public static function del($head, $id) {
    $curr = $head;
     
    while($curr->next != null) {
      if ($curr->next->id == $id) {
 $curr->next = $curr->next->next;
 return true;
      }
      $curr = $curr->next;
    }
  }
   
  
  public static function edit($head, $id, $new_name) {
    $curr = $head;
     
    while($curr->next != null) {
      if ($curr->next->id == $id) {
 $curr->next->name = $new_name;
      }
      $curr = $curr->next;
    }
  }
}
 
$head = new linkList();
linkList::add($head, 1, 'wangdk');
linkList::add($head, 2, 'sunshuzhen');
linkList::add($head, 8, 'wanghaha');
linkList::add($head, 6, 'wangchufen');
linkList::add($head, 6, 'wangchufen');
linkList::add($head, 3, 'wangdaye');
 
linkList::del($head, 1);
linkList::edit($head, 2, 'hahaha');
linkList::echo_link_list($head);
 
?>

链表的增删查改：

name = $name;
    $this->id  = $id;
  }
   
  
  public static function echo_link_list($head) {
    $curr = $head;
    while ($curr->next != null) {
      echo '姓名:'.$curr->next->name, ' 编号:'.$curr->next->id;
      echo '
';
      $curr = $curr->next;
    }
  }
   
  
  public static function add($head, $id, $name) {
    $curr = $head;
    $obj = new linkList($id, $name);
     
    while ($curr->next != null) {
      // 如果当前ID < 下一个ID,则添加到中间，添加节点到指定顺序位置
      if ($curr->next->id > $id) {
  
 $obj->next = $curr->next;
 $curr->next = $obj;
  
 return true;
      } else if ($curr->next->id == $id) {
  
 echo '当前Id:'.$id.'重复了，请不要继续添加了！';
 echo '
';
  
 return false;
      }
      $curr = $curr->next;
    }
    // 添加节点到尾部
    if ($curr->next == null) {
      $curr->next = $obj;
    }
  }
   
  
  public static function del($head, $id) {
    $curr = $head;
     
    while($curr->next != null) {
      if ($curr->next->id == $id) {
 $curr->next = $curr->next->next;
 return true;
      }
      $curr = $curr->next;
    }
  }
   
  
  public static function edit($head, $id, $new_name) {
    $curr = $head;
     
    while($curr->next != null) {
      if ($curr->next->id == $id) {
 $curr->next->name = $new_name;
      }
      $curr = $curr->next;
    }
  }
}
 
$head = new linkList();
linkList::add($head, 1, 'wangdk');
linkList::add($head, 2, 'sunshuzhen');
linkList::add($head, 8, 'wanghaha');
linkList::add($head, 6, 'wangchufen');
linkList::add($head, 6, 'wangchufen');
linkList::add($head, 3, 'wangdaye');
 
linkList::del($head, 1);
linkList::edit($head, 2, 'hahaha');
linkList::echo_link_list($head);
 
?>
