unexpected back slash

Hi,

I think there is an unexpected back slash:

/administrator/components/com_abook/views/books/viewhtml.php #40

		if (!\count($this->items) && $this->isEmptyState = $this->get('IsEmptyState'))

Hi iberan,
which version of Abook are you using?
I think you are referring to this file administrator/components/com_abook/views/book/view.html.php but the line #40 is totally different.

So sorry, Federica, this back slash appears in administrator/components/com_abook/views/books/view.html.php #40

iberan · 17 July 2023, 15:59:14

... and the version is Abook 4.01

I found the line you refers and the backslash.
Which PHP error occurs? My installation does not display any errors.

No any PHP error occurs, I can't recognize this character only.

It is an escape character useful to call a function.
Joomla core also do that
eg. components/com_contact/helpers/route.php line 16
you can see:

Code Select

\defined('_JEXEC') or die;)
