to get hourly and six hours based weather from NOAA - php

Question

I am trying to get the weather data from NOAA and parse it to get the current temperature, humidity, and other values. I am trying to get the JSON data from its website, which uses the latitude, and longitude values to get the weather data of location. I am getting trouble to get the data, and I found out we have to use CURl to get it done, and I have no idea on using CURL.
this is the URL i am using to get the data
"https://api.weather.gov/points/$latitude,$longitude/forecast".
This is what I tried, based on one example I found here. I want to know how to pass the latitude, and longitude, and add the forecast at the end in the url
<?php
/**

$url='https://api.weather.gov/points/'; //noaa url of choice
$params=array('39.7456','-97.0892','forecast');
$curl = curl_init();
curl_setopt($curl, CURLOPT_FAILONERROR, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, $params);
curl_setopt($curl, CURLOPT_URL, $url);
$result = curl_exec($curl);
$data = json_decode($result);
curl_close($curl);
echo "<pre>";
echo json_encode($data, JSON_PRETTY_PRINT);
echo "<pre>";
?>

Simply append the coordinates to the URL.
<?php
$ch = curl_init('https://api.weather.gov/points/39.7456,-97.0892/forecast');
curl_setopt_array($ch, [
CURLOPT_RETURNTRANSFER => true,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_SSLVERSION => 6,
CURLOPT_USERAGENT => 'Firefox',
]);
$response = curl_exec($ch);
if($response === false)
exit(curl_error($ch));
print_r(json_decode($response));
A few notes about the code :
Passing the URL to curl_init is the same as setting it with curl_setopt(CURLOPT_URL
curl_exec returns false on failure, hence the $response === false test. I used === in this case otherwise PHP may interpret an empty string as false, which doesn't make sense in this context.
The network connection would fail unless I set the SSL version to 6 (or CURL_SSLVERSION_TLSv1_2)
The API would forbid me from accessing the data unless I specified a believable user-agent, in this case Firefox.
