有没有在php利用类的好例子呀!

土八路你的网址无法访问的．给你一篇不错的文章我想你看过以后就可以理解类了．
http://www.cngnu.org/technology/0584/207.html

我写了一个简单的不能再简单的类.相信你会看懂的.<?php
class test
{
function aaa($a="aaa"){
echo $a;
} function bbb($b="bbb"){
echo $b;
} function ccc($c="ccc"){
echo $c;
}
}$test = new test;$test->aaa();
$test->bbb();
$test->ccc();
?>显示结果为
aaabbbccc就这么简单.依我理解.类就是一个函数的聚合罢了.比较适合像我这种比较懒的人..嘿嘿
