可显示多种图形报表的php图片类，包括竖柱形图，横柱形图，画柱形图，折线图，饼状图。
是学习php图像处理的好例子，供大家学习参考。

一、php类中数据类型
public: 公有类型
在子类中可以通过self::var 来调用 public类型的方法或属性 可以通过parent::method 来调用父类中的方法
在实例中可以能过$obj->var 来调用 public类型的方法或属性
protected: 受保护类型
在子类中可以通过self::var 来调用 protected类型的方法或属性 可以通过parent::method 来调用父类中的方法
在实例中不能通过$obj->var 来调用 protected类型的方法或属性
private: 私有类型
该类型的属性或方法只能在该类中使用，在该类的实例、子类中、子类的实例中都不能调用私有类型的属性和方法
二、self 和 parent 的区别
a).在子类中常用到这两个对像。他们的主要区别在于self可以调用父类中的公有或受保护的属性，但parent不可以调用
b).self:: 它表示当前类的静态成员(方法和属性) 与 $this 不同,$this是指当前对像
附代码：
<?php
/**
* parent 只能调用父类中的公有或受保护的方法，不能调用父类中的属性
* self 可以调用父类中除私有类型的方法和属性外的所有数据

首先，给大家演示一下调用示例：
$smtpserver = "*****";
$smtpserverport = 25;
$smtpuser = "******";
$smtppass = "*******";
$smtp = new smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass); //这里面的一个true是表示使用身份验证,否则不使用身份验证.
$smtp->debug = false;
//$emailtype ＝ "HTML";
for ($i=0; $i<5; $i++) {
$smtp->sendmail("*****", "******", "Hello world!","This is only a test!");
}
echo "共发送了 <b>$i</b> 封邮件！";
