how to use an api php code example

Example 1: php get data from api with key and id

function callAPI($method, $url, $data){
   $curl = curl_init();
   switch ($method){
      case "POST":
         curl_setopt($curl, CURLOPT_POST, 1);
         if ($data)
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
         break;
      case "PUT":
         curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
         if ($data)
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);			 					
         break;
      default:
         if ($data)
            $url = sprintf("%s?%s", $url, http_build_query($data));
   }
   // OPTIONS:
   curl_setopt($curl, CURLOPT_URL, $url);
   curl_setopt($curl, CURLOPT_HTTPHEADER, array(
      'APIKEY: 111111111111111111111',
      'Content-Type: application/json',
   ));
   curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
   // EXECUTE:
   $result = curl_exec($curl);
   if(!$result){die("Connection Failure");}
   curl_close($curl);
   return $result;
}

Example 2: external api php

<?php
function getServerStatistics($url) {
    $statisticsJson = file_get_contents($url);
    if ($statisticsJson === false) {
       return false;
    }

    $statisticsObj = json_decode($statisticsJson);
    if ($statisticsObj !== null) {
       return false;
    }

    return $statisticsObj;
}

// ...

$stats = getServerStatistics($url);
if ($stats !== false) {
    print $stats->players->online;
}

Example 3: php get data from api with key and id

$get_data = callAPI('GET', 'https://api.example.com/get_url/'.$user['User']['customer_id'], false);
$response = json_decode($get_data, true);
$errors = $response['response']['errors'];
$data = $response['response']['data'][0];

Example 4: rest api example php

CREATE TABLE `Transaction` (
  `id` int(11)  UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
  `comment` text,
  `price` float,
  `quantity` float,
  `reason` enum('New Stock','Usable Return','Unusable Return'),
  `createdAt` datetime NOT NULL,
  `updatedAt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `productid` int(11) NOT NULL
);
