To call an API in Codeigniter, you can use the HTTP client library cURL. Here's an example of how to do it:

  1. First, make sure that the cURL library is loaded:
1
$this->load->library('curl');


  1. Next, set the options for the cURL request. This can include the HTTP method (e.g. GET, POST), the URL of the API, and any data that you need to send with the request:
1
2
3
4
5
6
7
$options = array(
    CURLOPT_URL => 'https://api.example.com/endpoint',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $data
);
$this->curl->options($options);


  1. Finally, execute the cURL request and handle the response:
1
2
3
4
5
6
7
8
9
$response = $this->curl->execute();

if ($response === FALSE) {
    // There was an error executing the cURL request
    $error = $this->curl->error_string;
} else {
    // The request was successful
    // Process the response here
}


You can also use the GET, POST, PATCH, DELETE, etc. methods provided by the cURL library as a shortcut for setting the HTTP method and options:

1
2
$this->curl->get('https://api.example.com/endpoint');
$response = $this->curl->execute();

To call an API in CodeIgniter, you can follow these steps:

  1. Start by making sure that the cURL library is enabled in your PHP installation. You can check this by searching for the "extension=curl" line in your php.ini file. If it is commented out with a semicolon (;) at the beginning, remove the semicolon and save the file.
  2. Load the cURL library in your CodeIgniter controller or model. You can do this by adding the following code at the beginning of your file: defined('BASEPATH') OR exit('No direct script access allowed'); class Your_Controller extends CI_Controller { public function __construct() { parent::__construct(); $this->load->library('curl'); } }
  3. Use the cURL library to make the API request. For example, you can use the following code to make a GET request: $url = 'https://api.example.com/data'; $response = $this->curl->simple_get($url);
  4. You can also make POST requests using the cURL library. Here's an example: $url = 'https://api.example.com/data'; $data = array( 'param1' => 'value1', 'param2' => 'value2' ); $response = $this->curl->simple_post($url, $data);
  5. Handle the API response. The response can be in the form of JSON or XML. You can use PHP's json_decode() or SimpleXML functions to parse and manipulate the response data as needed. $decoded_response = json_decode($response); // Handle the response data


That's it! You have successfully called an API in CodeIgniter using the cURL library.
