Method in a class to access an array element

lukin

I am trying to write a very simple class and include a getter method to return an array element. My code is below. I must stress I am new to PHP.
The function I am using to get the value in the array is getArrayElement
The error I am getting is:
Notice: Undefined variable: guys in C:\XAMPP\htdocs\lab6\exercise3.php on line 10

Fatal error: Cannot access empty property in C:\XAMPP\htdocs\lab6\exercise3.php on line 10
Thanks for any replies.

[PHP]
<?php

class myFirstClass
{
public $guys = array("mike","pete","larry","pam");
public $t;
public function getArrayElement($arrIndex)
{
$t =$arrIndex;
return $this->$guys[$t];


}

}


$fc = new myFirstClass();


echo $fc->getArrayElement(3);




?>



[/PHP]

I sorted it; It was just a case of changing the line

return $this->$guys[$t];

to this:

return $this->guys[$t];

Removing the dollar sign before guys

Glad you sorted it. Have a look at this too: http://php.net/manual/en/language.variables.variable.php
It will explain.
