How to implement cURL on these parameters - php

Question

please I need your help.
I am working on a plagiarism api from Prepostseo, and I have been given this parameters to invoke using cURL. Now, I know little of cURL because I have been using file_get_contents. But now I am required to only use cURL. I have searched through their documentation, no reference material or source code available, not even on Github.
Here are the parameters, I need help please, on how to implement this:
curl -X POST https://www.prepostseo.com/apis/checkSentence \
-d "key=YOUR_KEY"
-d "query=Inside that cage there was a green teddy bear"
Thanks in advance!

For future reference, you can use the https://incarnate.github.io/curl-to-php
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.prepostseo.com/apis/checkSentence");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "key=YOUR_KEY&query=Inside that cage there was a green teddy bear");
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array();
$headers[] = "Content-Type: application/x-www-form-urlencoded";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
curl_close ($ch);
echo $result;
?>

This link explains everything you need to know about how to use cURL in PHP.
The code snippet below will POST through a URL-encoded query string to the specified URL.
When the cURL call is performed, the response is assigned to the $respsonse variable, and the cURL call is closed there after.
$payload = [
'key' => 'YOUR_KEY',
'query' = 'Inside that cage there was a green teddy bear'
];
$url = "https://www.prepostseo.com/apis/checkSentence";
//set up cURL - below is a general basic set up
$ch = curl_init( $url );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
//specify your method
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
//for the body values you wish to POST through
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($payload));
//specifiy any specific headers you need here in your array
curl_setopt($ch, CURLOPT_HTTPHEADER, []);
//execute and close cURL
$response = curl_exec($ch);
curl_close($ch);
