下面这个是基于php mysql的递归实现无限分类

数据库结构如下

实现如下效果

php程式代码

<?php

*
* php递归实现的无限分类
*
CREATE TABLE `article_class` (
`pcid` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`pcname` VARCHAR( 50 ) NOT NULL ,
`level` INT NOT NULL ,
`parentid` INT NOT NULL
) ENGINE = MYISAM ;
* __________________________________________________________*/

error_reporting(E_ALL);

//mysql_connect ...

$link = mysql_connect('localhost','root','');

mysql_select_db('test');

function tree($parentid) {

$result = mysql_query('Select * FROM `article_class` Where `parentid` = '.$parentid) OR die("Invalid query: " . mysql_error());;

while($r = mysql_fetch_array($result)) {

echo str_repeat('  ',$r['level']).$r['pcname'].'<br />';

tree($r['pcid']);

}

if(($parentid + 0) < 1){

$parentid = 0;

}

tree($parentid);

?>
