单链表是一种链式存取的数据结构，用一组地址任意的存储单元存放线性表中的数据元素。
单链表简介
链表中的数据是以结点来表示的，每个结点的构成：元素(数据元素的映象) + 指针(指示后继元素存储位置)，元素就是存储数据的存储单元，指针就是连接每个结点的地址数据。
关键代码如下所示：
PHP;">
id = $id;
$this->name = $name;
}
static public function show ($head)
{
$cur = $head;
while ($cur->next) {
echo $cur->next->id,'###',$cur->next->name,'
'; $cur = $cur->next; } echo '
'; } //尾插法 static public function push ($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) { $cur = $head; while (NULL != $cur->next) { if ($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);
'; $cur = $cur->next; } echo '
'; } //尾插法 static public function push ($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) { $cur = $head; while (NULL != $cur->next) { if ($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);
