I am getting array(0) in PHP yii2? - php

Question

I am getting array(0) as var_dump.
tbl_supplierOrderDetails['user_id']array(2) {
["tbl_supplierOrderDetails"]=>
array(0) {
}
["tbl_userContactDetails"]=>
array(0) {
}
}
Here is my API example using php yii2
public function actionSuggestions()
{
$listingId = Yii::$app->request->get('listing_id');
$apiUrl = "http://example.com:8800/api/Home/view_supplierOrderDetails?listing_id=".$listingId;
$suggestions = file_get_contents($apiUrl);
$suggestions = json_decode($suggestions, JSON_PRETTY_PRINT);
echo "tbl_supplierOrderDetails['user_id']";
//print_r($suggestions);
var_dump($suggestions);
exit;
return $this->render('suggestions' , array(
'listingId' => $listingId,
'suggestions' => $suggestions,
));
}
here is my api demo in json format.
{
"tbl_supplierOrderDetails": [
{
"num": 1,
"user_id": 3496,
"priority": "A.closed",
"no_of_times": 5,
"username": "eyuw",
"company_name": "djff",
"email": "abc#gmail.com",
"contact_no": "9999999999",
"origin": "abc",
"dest": "xyz",
"vehicle_class": "abc,
"vehicle_type": "abc",
"notes": "TCS_"
}]
"tbl_userContactDetails": [
{
"user_id": 500,
"contact_name": "Mr abc",
"contact_email": "abc#gmail.com",
"contact_mobile": 9999999999,
"contact_mobile2": null
}]
}
I want to display both this details in my html in different section . how can i do so by calling this api.

first of all, make sure that variable $suggestions contains what data you are expecting.
Your structure is completely wrong so, I would like to suggest you a good structure.
public function actionSuggestions() {
try {
$message = array();
$listingId = Yii::$app->request->get('listing_id');
if (!empty($listingId)) {
$apiUrl = "http://example.com:8800/api/Home/view_supplierOrderDetails?listing_id=" . $listingId;
$suggestions = file_get_contents($apiUrl);
$suggestions = json_decode($suggestions, JSON_PRETTY_PRINT);
//if $suggestions contains required data then you can return those data
$message = ['status' => 'success', 'message' => 'Data fetched succesfully', 'data' => $suggestions];
//else build an array like what format you want
} else {
$message = ['status' => 'failed', 'message' => 'Missing parameters.'];
}
} catch (\Exception $exception) {
$message = ['status' => 'failed', 'message' => "Some exception occured."];
}
return $message;
}
Here you can expect json output like the following:
{
"status" : "success",
"message" : "Data fetched succesfully",
"data" : {
}
}
