Php error help

[Buvian]

First of let me start by saying I have not a clue about PHP and coding in general. I'm running a PHP/MySQL Chat bot for a game I play and I have a module that I'm having issues with. The script is for recruiting people. This is the error it keeps throwing. Fatal error: Can't use method return value in write context in /home/guild/service48/modules/aoc/Ginfo.php on line 19

 

This is the PHP code. Any help would be greatly appreciated and I'm sorry if I posting in wrong section. I would ask the developers, but they do not monitor the project often.
