HTTP GET Request:

Make a basic HTTP GET request to an external API and retrieve data.

$ch = curl_init('https://api.example.com/data');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

HTTP POST Request with Form Data:

Send data to an API using an HTTP POST request with form parameters.

$postData = ['key1' => 'value1', 'key2' => 'value2'];
$ch = curl_init('https://api.example.com/post-endpoint');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
$response = curl_exec($ch);
curl_close($ch);

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class YourController extends Controller
{
    public function makePostRequest()
    {
        // URL endpoint for the POST request
        $url = 'https://example.com/api/endpoint';

        // Form data to be sent in the POST request
        $formData = [
            'key1' => 'value1',
            'key2' => 'value2',
            // Add more key-value pairs as needed
        ];

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

        // Set cURL options
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $formData);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        // Execute cURL session and get the response
        $response = curl_exec($ch);

        // Check for cURL errors
        if (curl_errno($ch)) {
            // Handle error
            echo 'cURL Error: ' . curl_error($ch);
        }

        // Close cURL session
        curl_close($ch);

        // Process the response
        // For example, you can return it as a response from the controller
        return response()->json(['response' => $response]);
    }
}

HTTP POST Request with JSON Data:

Send JSON data to an API using an HTTP POST request.

$jsonData = json_encode(['key' => 'value']);
$ch = curl_init('https://api.example.com/post-json-endpoint');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
$response = curl_exec($ch);
curl_close($ch);

Handling HTTP Headers:

Include custom headers in your cURL request.

$ch = curl_init('https://api.example.com/data');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Authorization: Bearer YOUR_ACCESS_TOKEN']);
$response = curl_exec($ch);
curl_close($ch);

File Upload with POST Request:

Upload a file to a server using an HTTP POST request.

$fileData = ['file' => new \CURLFile('/path/to/file.txt')];
$ch = curl_init('https://api.example.com/upload');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fileData);
$response = curl_exec($ch);
curl_close($ch);

Handling Cookies:

Send and receive cookies in your cURL request.

$ch = curl_init('https://api.example.com/data');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIE, 'cookie_name=cookie_value');
$response = curl_exec($ch);
curl_close($ch);

Following Redirects:

Allow cURL to automatically follow redirects.

$ch = curl_init('https://api.example.com/redirecting-endpoint');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$response = curl_exec($ch);
curl_close($ch);

Asynchronous Requests:

Perform asynchronous requests using cURL multi handles.

$ch1 = curl_init('https://api.example.com/endpoint1');
$ch2 = curl_init('https://api.example.com/endpoint2');

$mh = curl_multi_init();
curl_multi_add_handle($mh, $ch1);
curl_multi_add_handle($mh, $ch2);

do {
    curl_multi_exec($mh, $running);
} while ($running > 0);

curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_close($mh);

Setting Timeout for Requests:

Set a timeout for cURL requests to avoid waiting indefinitely.

$ch = curl_init('https://api.example.com/data');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10); // Set timeout to 10 seconds
$response = curl_exec($ch);
curl_close($ch);

HTTP DELETE Request:

Make an HTTP DELETE request to an API.

$ch = curl_init('https://api.example.com/resource-to-delete');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'DELETE');
$response = curl_exec($ch);
curl_close($ch);

These examples cover a variety of common use cases for working with cURL in Laravel, from basic requests to more advanced scenarios. Depending on your specific needs, you can adapt these examples to suit your Laravel application.
