Php 致命错误:无法重新声明类pDraw

Php 致命错误:无法重新声明类pDraw,php,yii,pchart,Php,Yii,Pchart,我正在使用Yii框架从mPDF库生成pdf。对于这个PDF,我需要添加在服务器上生成的图表,因此我使用pChart库来生成它们。我创建了一个简单的对象类,以更简单的方式为PDF设置pChart属性 这是类对象: <?php Class Chart { protected $fontsFolder = null; protected $data = array(); protected $resolution = array(); public $char

我正在使用
Yii
框架从
mPDF
库生成pdf。对于这个PDF,我需要添加在服务器上生成的图表,因此我使用
pChart
库来生成它们。我创建了一个简单的对象类,以更简单的方式为PDF设置
pChart
属性

这是类对象:

使用
包含一次
而不是
包含

include_once('pDraw.class.php');
include_once('pImage.class.php');
include_once('pData.class.php');

谢谢你,这就成功了,我现在觉得自己很笨,我现在意识到我还是一个新手程序员
include_once('pDraw.class.php');
include_once('pImage.class.php');
include_once('pData.class.php');
