php如何调用方法

本类中普通方法调用

$fundList =$this->getOnsaleFundList();

本类中静态方法调用 （推荐学习：PHP视频教程）

$fundList =self::getOnsaleFundList();

调用其他类的普通方法

$objFix = new ApiAssemble();

 $objFix->setUser($obj);

调用其他类的静态方法

$objFix = ApiAssemble::setUser($obj);

代码：

<?php
	// 最常见的函数调用 --- 1
	function userFunction1($param1, $param2){
		echo &#39;UserFunction1: Param1 : &#39;,$param1,&#39; , Param2 : &#39;,$param2,&#39;<br/>&#39;;
	}
	userFunction1(&#39;Hello&#39;,&#39;world&#39;);
 
	// 最常见的函数调用 --- 2
	$userFunction2 = function($param1, $param2){
		echo &#39;UserFunction2: Param1 : &#39;,$param1,&#39; , Param2 : &#39;,$param2,&#39;<br/>&#39;;
	};
	$userFunction2(&#39;Hello&#39;, &#39;PHP&#39;);
 
	// 作为回调函数的函数调用 --- 1
