-# Restclient
+# RestClient
-Client for interacting with REST apis
+
+The `RestClient` is a versatile PHP class for making HTTP requests using cURL, with support for handling JSON responses, custom headers, file downloads, and cookies.
+
+## Features
+
+- Supports `GET`, `POST`, `PUT`, `DELETE` HTTP methods
+- Handles JSON requests and responses
+- Supports custom headers and user-agent strings
+- Maintains session using cookies (optional)
+- Can download files
+- Throws exceptions for HTTP errors (configurable)
+- Retrieves HTTP response codes
+
+## Installation
+
+To use the `RestClient` class in your PHP project:
+
+Setup this registry in your ~/.composer/config.json file:
+```json
+{
+	"repositories": [{
+			"type": "composer",
+			"url": "https://git.hpz.pw/api/packages/hpz937/composer"
+		}
+	]
+}
+```
+
+To install the package using Composer, run the following command:
+```
+composer require hpz937/restclient
+```
+
+## Usage
+
+### Basic Usage
+
+You can start by creating an instance of `RestClient` and configuring options such as base URL, headers, or whether to use cookies.
+
+```php
+use Hpz937\Restclient\RestClient;
+
+$client = new RestClient();
+$client->setBaseUrl('https://api.example.com');
+```
+
+### HTTP GET Request
+
+Perform a simple GET request to an API endpoint.
+
+```php
+$response = $client->get('/endpoint')
+                   ->getResponse();
+
+echo $response;
+```
+
+### HTTP POST Request
+
+Send data to the API using a POST request.
+
+```php
+$data = [
+    'name' => 'John Doe',
+    'email' => 'john@example.com',
+];
+
+$response = $client->post('/endpoint', $data)
+                   ->getResponse();
+
+echo $response;
+```
+
+### HTTP PUT Request
+
+Update resources using a PUT request.
+
+```php
+$data = [
+    'name' => 'Jane Doe',
+];
+
+$response = $client->put('/endpoint/123', $data)
+                   ->getResponse();
+
+echo $response;
+```
+
+### HTTP DELETE Request
+
+Delete a resource using a DELETE request.
+
+```php
+$response = $client->delete('/endpoint/123')
+                   ->getResponse();
+
+echo $response;
+```
+
+### Handling JSON Responses
+
+To handle JSON responses, you can use the `decodeJson` method to convert the response into an associative array.
+
+```php
+$response = $client->get('/endpoint')
+                   ->decodeJson();
+
+print_r($response);
+```
+
+### Custom Headers
+
+You can set custom headers for your requests.
+
+```php
+$headers = [
+    'Authorization: Bearer YOUR_TOKEN',
+    'Accept: application/json',
+];
+
+$client->setHeaders($headers);
+```
+
+### Setting User-Agent
+
+Set a custom `User-Agent` string for the requests.
+
+```php
+$client->setUserAgent('MyCustomUserAgent/1.0');
+```
+
+### File Downloads
+
+You can download files using the `download` method. Make sure to specify the filename where the file will be saved.
+
+```php
+$client->download('/path/to/file.jpg', '/local/path/to/save/file.jpg')
+       ->get('/endpoint/download-file');
+
+echo "File downloaded successfully!";
+```
+
+### Using Cookies
+
+Enable cookies to maintain session data between requests.
+
+```php
+$client->setUseCookies(true);
+```
+
+### Exception Handling for HTTP Errors
+
+By default, the `RestClient` throws exceptions when HTTP errors (4xx, 5xx) occur. You can handle these exceptions as follows:
+
+```php
+try {
+    $client->get('/invalid-endpoint')
+           ->getResponse();
+} catch (Exception $e) {
+    echo 'Error: ' . $e->getMessage();
+}
+```
+
+### Getting the HTTP Response Code
+
+Retrieve the HTTP response code from the most recent request.
+
+```php
+$responseCode = $client->getResponseCode();
+
+echo "HTTP Response Code: $responseCode";
+```
+
+## Example Workflow
+
+```php
+use Hpz937\Restclient\RestClient;
+
+$client = new RestClient();
+$client->setBaseUrl('https://api.example.com')
+       ->setUserAgent('MyApp/1.0')
+       ->setHeaders([
+           'Authorization: Bearer YOUR_API_KEY',
+           'Content-Type: application/json',
+       ])
+       ->setUseCookies(true);
+
+try {
+    // GET request example
+    $response = $client->get('/users')
+                       ->decodeJson();
+    print_r($response);
+    
+    // POST request example
+    $data = ['name' => 'New User'];
+    $response = $client->post('/users', $data)
+                       ->getResponse();
+    echo $response;
+    
+} catch (Exception $e) {
+    echo 'Request failed: ' . $e->getMessage();
+}
+```
