Answer 1

Looks like you were able to figure it out from the comments and the other answer. However, I should clarify that my comments on the question were slightly misleading, so you can disregard them. I actually assumed class referred to PHP objects, when in fact class was simply a key for a string (the array looks to me like some parsed HTML/XML). I realized this when you posted a var_dump() of the array in the comments.
The issue is that the array structure is fairly complicated with all the nesting going on, so it may be difficult to see what's what. In general, I agree with the other answer; debugging with var_dump() is a great way to check. Here's my take on what the answer might be.
Assuming your array variable is $array:
1.
$array['query']['results']['div'][0]['span']['a']['href']
$array['query']['results']['div'][0]['span']['a']['img']['src']
2.
$array['query']['results']['div'][1]['span']['p']
3.
$array['query']['results']['span'][0]['content']
4.
$array['query']['results']['span'][1]['content']

Answer 2

try this:
if this array is in a variable named $array
1-$array['query']['result']['div'][0]['a']['href']
2-$array['query']['result']['div'][1]['p']
3-$array['query']['result']['span'][0]['class']
To debug and find the desired value, try to do like that,
var_dump($array['query']);
then
var_dump($array['query']['result']);
...etc
