XAMPP: How to upgrade PEAR

Question

When trying to upgrade XAMPP pear the following error is raised:

Fatal error: Cannot use result of built-in function in write context in C:\xampp\php\pear\Archive\Tar.php on line 639

Some suggestions how to fix this?

Answer 1

Just change in Tar.php

$v_att_list = & func_get_args(); 

to

$v_att_list = func_get_args();

PD:Tested over PHP 7.2 in Xammp

Answer 2

Usually this means you have a function inside a fuction, and sometimes it doesn't like that.

As an example, if this caused the error:

if(!isset(Session::get($something))){ 

Then you could change it to this to fix the problem:

$value = Session::get($something);
if(!isset($value)){
