Just wondering when I'm declaring on my view file I always got this error Undefined offset: 1

But when I change the array from [1-5] to [0] it works okay but it didn't get any data at all? If you see whats causing this, posting below would really help. Thanks! :)

It seems you meant to replace your auth token with an abstraction, but you've actually replaced your URL and left your token in place. You probably want to change/revoke that token immediately. — Alex Howansky, Sep 12 '18 at 17:09
Print your array and check array having actually offsets that you are accessing — , Sep 12 '18 at 17:10
@AlexHowansky I just need to hide my api key. that's why I leave my auth token out there. But thank you for reminding me. — Christian Gallarmin, Sep 12 '18 at 18:06

First of all, change your $array_issues declaration to either

$array_issues = array();

or

$array_issues = [];

Then, i don't know what you are trying to accomplish in this lines:

$results = json_decode($server_output2);

$j=0;
// to get each object from an array of object
foreach((array)$results as $result){ 
    if($j==3)
    $array_issues[$i] = $result;

    $j++;
}

But, i don't think this is initializing your $array_issues[0] index correctly, it may not even be entering this... i would at least initialize the index outside that if and foreach, something like:

$j=0;
// to get each object from an array of object
$array_issues[$i] = ""; // MAKING SURE THIS IS AT LEAST DEFINED.
foreach((array)$results as $result){ 
    if($j==3)
    $array_issues[$i] = $result;

    $j++;
}

Also, i think you could accomplish what you are trying to do with a $key => $value syntax instead of that $j counter...

$array_issues[$i] = ""; // MAKING SURE THIS IS AT LEAST DEFINED.
foreach((array)$results as $key => $result){ 
    if($key==3)
    $array_issues[$i] = $result;
}

$key => $value syntax? ... supposing the array keys are numeric, i added it to the answer – Erubiel Sep 12 '18 at 18:20
tried that already. but when i var_dump($array_issues); All of them is zero – Christian Gallarmin Sep 12 '18 at 18:44
Where are you dumping it ? After all this runs ? In the view ? – Erubiel Sep 12 '18 at 18:50
at the controller. – Christian Gallarmin Sep 12 '18 at 18:51
I think its because of my X-Auth-Token is not updated that's why. – Christian Gallarmin Sep 12 '18 at 19:11
The session token remains valid for 6 hours, then must be regenerated. Source : http://api-docs.deepcrawl.com/ – Christian Gallarmin Sep 12 '18 at 19:24
Was it really that ? i don't think that matters, 6 hours should be long enough. – Erubiel Sep 12 '18 at 19:25
