Using a custom function in a Laravel 5 Controller - function

Question

I'm using a Laravel 5, I just want to know how to use or declare a custom function inside my controller. I have
class UploadController extends Controller
{
function on_request_done($content, $url, $ch, $search) {
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($httpcode !== 200) {
print "Fetch error $httpcode for '$url'\n";
return;
}
$responseobject = json_decode($content, true);
if (empty($responseobject['responseData']['results'])) {
print "No results found for '$search'\n";
return;
}
print "********\n";
print "$search:\n";
print "********\n";
$allresponseresults = $responseobject['responseData']['results'];
foreach ($allresponseresults as $responseresult) {
$title = $responseresult['title'];
print "$title\n";
}
}
}
And whenever I call on_request_done inside one of my functions let's say,
public function getParallelApi()
{
define ('SEARCH_URL_PREFIX', 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&rsz=large&filter=0');
$terms_list = array(
"John", "Mary",
"William", "Anna",
"James", "Emma",
"George", "Elizabeth",
"Charles", "Margaret",
"Frank", "Minnie",
"Joseph", "Ida",
"Henry", "Bertha",
"Robert", "Clara",
"Thomas", "Alice",
"Edward", "Annie",
"Harry", "Florence",
"Walter", "Bessie",
"Arthur", "Grace",
"Fred", "Ethel",
"Albert", "Sarah",
"Samuel", "Ella",
"Clarence", "Martha",
"Louis", "Nellie",
"David", "Mabel",
"Joe", "Laura",
"Charlie", "Carrie",
"Richard", "Cora",
"Ernest", "Helen",
"Roy", "Maude",
"Will", "Lillian",
"Andrew", "Gertrude",
"Jesse", "Rose",
"Oscar", "Edna",
"Willie", "Pearl",
"Daniel", "Edith",
"Benjamin", "Jennie",
"Carl", "Hattie",
"Sam", "Mattie",
"Alfred", "Eva",
"Earl", "Julia",
"Peter", "Myrtle",
"Elmer", "Louise",
"Frederick", "Lillie",
"Howard", "Jessie",
"Lewis", "Frances",
"Ralph", "Catherine",
"Herbert", "Lula",
"Paul", "Lena",
"Lee", "Marie",
"Tom", "Ada",
"Herman", "Josephine",
"Martin", "Fanny",
"Jacob", "Lucy",
"Michael", "Dora",
);
if (isset($argv[1])) {
$max_requests = $argv[1];
} else {
$max_requests = 10;
}
$curl_options = array(
CURLOPT_SSL_VERIFYPEER => FALSE,
CURLOPT_SSL_VERIFYHOST => FALSE,
CURLOPT_USERAGENT, 'Parallel Curl test script',
);
$parallel_curl = new ParallelCurl($max_requests, $curl_options);
foreach ($terms_list as $terms) {
$search = '"'.$terms.' is a"';
$search_url = SEARCH_URL_PREFIX.'&q='.urlencode($terms);
$parallel_curl->startRequest($search_url, 'on_request_done', $search);
}
$parallel_curl->finishAllRequests();
//return "Helloo";
}
I get
call_user_func() expects parameter 1 to be a valid callback, function 'on_request_done' not found or invalid function name
My route
Route::get('/parallelapi', 'UploadController#getParallelApi');
PLEASE NOTE THAT getParallelApi() is under UploadController as well.

Answer 1

The problem is you are passing in the name of the function but it has no idea what class that function exists in. You should be able to do this by passing an array as your callback with the first item being an instance of your controller and the second item being the name of the function.
$parallel_curl->startRequest($search_url, [$this, 'on_request_done'], $search);
