How to Retrieve API Responses Using cURL in PHP?

Obtaining Response Using cURL in PHP

In the domain of PHP programming, obtaining responses from an API via cURL can be a common requirement. To address this need, let's explore a comprehensive solution that involves creating a standalone PHP class.

<code class="php">class ApiCaller {
    public function getResponse($url) {
        $options = [
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_HEADER         => false,
            CURLOPT_FOLLOWLOCATION => true,
            CURLOPT_MAXREDIRS      => 10,
            CURLOPT_ENCODING       => "",
            CURLOPT_USERAGENT      => "test",
            CURLOPT_AUTOREFERER    => true,
            CURLOPT_CONNECTTIMEOUT => 120,
            CURLOPT_TIMEOUT        => 120,
        ];

        $ch = curl_init($url);
        curl_setopt_array($ch, $options);

        $content  = curl_exec($ch);
        curl_close($ch);

        return $content;
    }
}</code>

To utilize this class, you can instantiate it and call the getResponse function:

<code class="php">$apiCaller = new ApiCaller();
$response = $apiCaller->getResponse("http://example.com/api/endpoint");</code>

The $response variable will contain the response from the API. You can then decode it or process it as needed. This approach provides a modular and reusable way to make cURL requests in PHP.
