问题还在于：可以将功能从外部源添加到FPDF中吗????
我想从原始FPDF类中分离出一些“items”函数，并使用include或require将它们添加回该类。所有“包含”功能都是我项目的一种“模板”。我将拥有不同数量的项目/功能。拥有原始类中的所有函数会使代码很长。我想在自己的php文件中拥有每组“items”的函数，然后将它包含在类中......这可能吗？
这是我得到的错误：PHP致命错误：在/ home /....

您可以创建具有此附加信息的帮助程序类：
class PDFHelper {
public static function addCell($instance, ...) {
}
public static function setHeader($instance, ...) {
}
}
然后在主要班级：
class PDFReceipt extends FPDF {
PDFHelper::addCell($this, 95, 20, "Color");
/* ... */
}
