API With POST Parameters in PHP

API parameters can be passed not only via the GET method but also via the POST method. Let's see how this is done. Let our API expect data via the POST method:

api.loc/index.php<?php
  echo mt_rand($_POST['num1'], $_POST['num2']);
?>

Let's make a request to this API. For this, we will need the CURL library. Let's make a POST request using it:

tst.loc/index.php<?php
  $url = 'http://api.loc/index.php';
  
  $curl = curl_init();
  curl_setopt($curl, CURLOPT_URL, $url);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($curl, CURLOPT_POST, 1);
  
  $data = ['num1'=>'1', 'num2'=>'100'];
  curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
  
  $res = curl_exec($curl);
  
  var_dump($res);
?>
