[英]what is the difference between reference function and normal function in PHP5.3?
hi I am a php developer. 嗨,我是一名PHP开发人员。
Recently I got an old project using php5 which I have to upgrade to PHP5.3. 最近,我有一个使用php5的旧项目,我必须升级到PHP5.3。
In old version of php5 coding they declare functions in two different ways 在旧版本的php5编码中,它们以两种不同的方式声明函数
public function &getMyname(){ }
Some other place they are defining like normal 他们定义的其他一些地方像平常一样
public function getMyname(){ }
What is the difference between these two declarations. 这两个声明之间有什么区别。
The first method will return by reference. 第一种方法将通过引用返回。
