This PHP script api.php is designed to set up an API endpoint using the Xcrud library. It provides a simple way to interact with a database for CRUD (Create, Read, Update, Delete) operations. Here’s a breakdown of what the code does:

<?php
    //Save this file api.php somewhere accessible
    //$xcrud->table('products');
    echo "<br><a href='../api_GET.php'>GET link</a>";
    echo "<br><a href='../api_UPDATE.php'>UPDATE link</a>";
    echo "<br><a href='../api_DELETE.php'>DELETE link</a>";
    echo "<br><a href='../api_PUT.php'>PUT/INSERT link</a>";

    $xcrud = Xcrud::get_instance();
    $xcrud->table("payments");
    $xcrud->columns("customerNumber,checkNumber,amount");
    $xcrud->token('key123!');// Set Bearer token for authentication
    $xcrud->response_message(array("PUT"=>"Successfully inserted record","DELETE"=>"Successfully deleted record","POST"=>"Successfully Updated record"));//response message
    $xcrud->limit(10);// this applies for GET number of records
    //$json_data = $xcrud->render('api');
    //echo $json_data;


    //ACCEPTS PUT, GET, POST, UPDATE on api,php
   
    //GET
    /*

    <?php
        // URL of the API endpoint
        $url = 'http://localhost/xCrud_1.7.25.2/api.php';

        // Bearer token
        $bearerToken = 'key123!';

        // Initialize cURL session
        $ch = curl_init($url);

        // Set the options for cURL
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the response as a string
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
            'Authorization: Bearer ' . $bearerToken
        ));

        // Execute the request
        $response = curl_exec($ch);

        // Check for errors
        if (curl_errno($ch)) {
            echo 'cURL Error: ' . curl_error($ch);
        } else {
            // Output the response
            echo $response;
        }
