PHP notice because array is empty - howto avoid?

[closer2u2]

This code

$x=$rs->getarray();

$list=explode("|", $x[0]['poll_answer']);

Gives me a php notice

PHP Notice: Undefined offset: 0

So, if I understand it well, the array is empty in this case, what to adjust in the code so it will not give me the notice anymore?

Check that the array is not empty by using [man]empty[/man] or [man]count/man.

[closer2u2]

something like if (!empty($x)) { ...

or do you mean otherwise?

Yes, do something along those lines.
