API returns NULL response sometimes - php

I am making a API request in my web app which looks like this:
<?php
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://******.com/jdconnectionpool/view?
requestAction=JOB_FILE_DETAILS&job_no=7476709",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"accept: application/json",
"cache-control: no-cache"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
Everything looks to be fine. However, it returns null sometimes for the same set of params on calling multiple times. I do not seem to find any pattern either. Any far fetched information from someone who has experienced this phenomenon would be really appreciated.

cannot resolve URL in PHP

When I make a request with cURL gives error "cannot resolve host URL". Should I encode URL? After I encoded Google API URL, it still gives error.
https://developers.google.com/people/api/rest/v1/contactGroups/batchGet
GET https://people.googleapis.com/v1/contactGroups:batchGet
Where is the problem?
<?php
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "https://people.googleapis.com/v1/contactGroups:batchGet",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"Cache-Control: no-cache"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
I don't see anything wrong with the code, and I tested it and it worked fine.
I guess it's some issue with the DNS that can't resolve the host.

PHP cURL with API Key and Secret (Postman)

I'm working with an API which is made by a classmate. I used Postman to generate the PHP cURL for the connection, with Authorization Basic. This works perfectly. Now, I want to get rid of the Authorization Basic and use my own API Key & Secret (password). Are there any good ways to do this?
Thanks in advance!
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "Some link here",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"authorization: Basic //something here",
"cache-control: no-cache",
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
$result = json_decode($response,true);
}

IP long string filter

Hey,
i am trying to only show 1 bit of the long string i get from the api i got fram postman, the only thing i need to show is the city. How do i need do this?
i'm trying to find a way with php but i have no clue what to do
a:14:{s:10:"regionName";s:10:"California";s:6:"status";s:7:"success";s:4:"city";s:13:"Mountain View";s:8:"timezone";s:19:"America/Los_Angeles";s:7:"country";s:13:"United States";s:11:"countryCode";s:2:"US";s:3:"zip";s:0:"";s:3:"lon";d:-122.08499908447266;s:3:"isp";s:6:"Google";s:2:"as";s:19:"AS15169 Google Inc.";s:5:"query";s:7:"8.8.8.8";s:6:"region";s:2:"CA";s:3:"lat";d:37.42290115356445;s:3:"org";s:6:"Google";}
(im using the ip of google just for this question)
so the length of the city name changes!
the site where i got it frm http://ip-api.com/php/8.8.8.8
and the code i am using:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "http://ip-api.com/php/8.8.8.8",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"cache-control: no-cache",
"postman-token: 2e83e542-a6fb-5bb6-94e0-c1908282a2a2"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
That's a product of running a PHP variable in a PHP serialize you can reverse it with unserialize
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => "http://ip-api.com/php/8.8.8.8",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"cache-control: no-cache",
"postman-token: 2e83e542-a6fb-5bb6-94e0-c1908282a2a2"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
$responseArray = unserialize($response); //You probably need some error trapping here
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $responseArray["country"];
}
