How to solve the syntax problem?

Question

PHP

Parse error: syntax error, unexpected '.', expecting ',' or ';'
And so in the lines that have a line gluing in the fields. Anyone faced?

Answer 1

The $parts array is formed from the value of $this->request->get['path'] by splitting this value into parts at the underscore character. If $this->request->get['path'] is empty, then $parts will be empty and an error will occur.
Since $category_id is allowed to be null later in the script, add $parts = array(0); before the 45th line, the error will disappear. And it's better to do:

//-- GET ALL PRODUCTS FILTER BY CATEGORY
if(isset($this->request->get['path'])) {
$parts = explode('_', (string)$this->request->get['path']);
$category_id = (int)array_pop($parts);
} else {
$category_id = 0;
}

Answer 2

First, does it refer to itself? O_O How is it theoretically even supposed to work?
Second, you can't do that.
In the constructor, sculpt if you need to do so.

Answer 3

Tell me, is it generally correct to set so many properties?
Do I understand correctly that in the context of a large property system, classes should be grouped into DTOs?
