[i need help making my api files]

hi i need help making my api files here the following code

License Activation using the “POST” method
Description: Request to validate a license key and also log/write the user’s data into the database. You have to use this method upon software activation so InstaMember can count or limit the usage properly.
API End-Point: http://YOURDOMAIN.COM/!/instamember_api/license/{license_key}
PHP Example:
<?php
$secret_key = ‘YOUR SECRET KEY’; $license_key = ‘LICENSE KEY HERE’;
$md5_hash = md5($license_key . $secret_key);
$api_url = “http://yourdomain.com/!/instamember_api/license/{$license_key}”;
$hostname = @gethostbyaddr($_SERVER['SERVER_ADDR']); $data = array(
'domain' => $_SERVER['HTTP_HOST'], 'userip' => $_SERVER['REMOTE_ADDR'],
'servip' => ( $hostname ) ? $hostname : $_SERVER['SERVER_ADDR']
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_USERPWD, "{$secret_key}:{$md5_hash}"); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
$result = curl_exec($ch); $response = json_decode($result);
If ( $response->status == ‘Success’ ) {
// code to unlock software here…
} else {
// code handling error here…
}
License Validation using the “GET” method
Description: Request to validate the license whether the license is still active or invalid (e.g. expired, inactive, suspended, etc). This method does not accept any type of data, and will not log any data into the database.
API End-Point: http://YOURDOMAIN.COM/!/instamember_api/license/{license_key}
PHP Example:
<?php
$secret_key = ‘YOUR SECRET KEY’; $license_key = ‘LICENSE KEY HERE’; $md5_hash = md5($license_key . $secret_key);
$api_url = “http://yourdomain.com/!/instamember_api/license/{$license_key}”;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_USERPWD, "{$secret_key}:{$md5_hash}"); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$response = json_decode($result);
If ( $response->status == ‘Expired’ ) {
// the license key is expired… do something here… } else if ( $response->status == ‘Suspended’ ) {
// the license key has been suspended… do something here…
} else {
// do something here…
}
