PHP: Notice when error_reporting(E_ALL)

Question

When I try to access info that is not presented in xml like so: $someInfo = $element->blabla->cats[0]->src;
PHP shows notice like this: Notice: Trying to get property of non-object
How would I settle the matter?

Answer 1

Either $element, blabla, or cats[0] is not an object, and thus can't contain any elements.

Use isset():

if (isset($element->blabla->cats[0]->src))
 echo $element->blabla->cats[0]->src;

one isset() should do, no need to check every part consecutively.

This should do the job even if cats exists but is not an array.

Answer 2

you can use isset to verify if object property exists, like this:

if (isset ($element->blabla) && isset ($element->blabla->cats) && etc..)

if you just don't want to see the notice, use error_reporting(E_ALL & ~E_NOTICE)

Answer 3

Or alternative (but wrong way) you can suppress log in your php script by:

error_reporting(E_ERROR);

Which will force php to report only fatal errors.

Anyway, use Pekka solution.
