How to Utilize cURL to Fetch API Responses in PHP

In PHP, leveraging standalone classes to call APIs using cURL and retrieve responses is a common practice. To assist with this, here is a resourceful code snippet that can be incorporated into your PHP class:

$response = get_web_page("http://socialmention.com/search?q=iphone apps&f=json&t=microblogs&lang=fr");
$resArr = array();
$resArr = json_decode($response);

echo "

";<br>print_r($resArr);<br>echo "

";

function get_web_page($url) {

$options = array(
    CURLOPT_RETURNTRANSFER => true,   // Return web page
    CURLOPT_HEADER         => false,  // Exclude headers
    CURLOPT_FOLLOWLOCATION => true,   // Follow redirects
    CURLOPT_MAXREDIRS      => 10,     // Restrict to 10 redirects
    CURLOPT_ENCODING       => "",     // Handle compressed content
    CURLOPT_USERAGENT      => "test", // Specify the user agent
    CURLOPT_AUTOREFERER    => true,   //Automatically set referer on redirects
    CURLOPT_CONNECTTIMEOUT => 120,   // Timeout for connections
    CURLOPT_TIMEOUT        => 120    // Timeout for responses
);
$ch = curl_init($url);
curl_setopt_array($ch, $options);

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

return $content;

}
?>

This code snippet epitomizes the standard functionality of a PHP class that interacts with APIs through cURL. Essentially, it receives an API URL, invokes cURL to retrieve the API response, parses the response as JSON if necessary, and showcases the results in a readable format.
