严格标准：只能通过引用传递变量（qdig gallery）

Question

The code from Qdig Gallery is:

$excl_imgs[] = end($logo_arrray = explode('/', $header['css_logo_url']));
$excl_imgs[] = end($bg_img_array = explode('/', $header['css_bg_img_url']));

which gives the above error (Strict Standards).

How do I fix this?

Answer 1

Do this instead and your error should go away:

$logo_arrray = explode('/', $header['css_logo_url']);
$bg_img_array = explode('/', $header['css_bg_img_url']);

$excl_imgs[] = end($logo_arrray);
$excl_imgs[] = end($bg_img_array);

You should always try and fix any Strict Standards warning and not just hide them.
