[DLE] How to remove error when inserting php code into tpl?

Question

PHP

I actually output the php code to the tpl file as follows: {include file="engine/modules/giveitem.php"}
giveitem.php in turn includes the shop.php file. In the output I get the following error:

Warning: stream_set_timeout() expects parameter 1 to be resource, boolean given in Z:\home\mine.ru\www\engine\modules\shop.php on line 36 Warning: fwrite() expects parameter 1 to be resource, boolean given in Z:\home\mine.ru\www\engine\modules\shop.php on line 57 Warning: fwrite() expects parameter 1 to be resource, boolean given in Z:\home\mine.ru\www\engine\modules\shop.php on line 57 Warning: fwrite() expects parameter 1 to be resource, boolean given in Z:\home\mine.ru\www\engine\modules\shop.php on line 57

Just in case, I provide the code of these php files.
giveitem.php - pastebin.com/ynRyXt91
shop.php - pastebin.com/4RXSR9JW

Answer 1

There is a suspicion that the modules you installed are not adapted to your version of DLE.

Answer 2

1. The error is that after opening the socket you do not check the success of its opening.
2. Use __construct instead of a method with name = class name
PS There is one more problem, but I don't think it can be fixed.

Answer 3

What is the DLE version? Sometimes it is necessary to make changes to index.php in order to correctly process such pieces of code
