Answer 1

you should first check if photo key is exist in $resp['results'][$i] array by using isset function in php
for example
if(isset($resp['results'][$i]['photos']) && count($resp['results'][$i]['photos']) > 0)
{
// write your code
}
and also you should use phpenter code here count function to check $resp['results'][$i]['photos'] array has multi entry
so you can write $resp['results'][$i]['photos'][0] without have out of scope error
