How to get response using cURL in PHP

Question

I want to have a standalone PHP class where I want to have a function which calls an API through cURL and gets the response. Can someone help me in this?

Thanks.

Answer 1

Just use the below piece of code to get the response from restful web service url, I use social mention url.

$response = get_web_page("http://socialmention.com/search?q=iphone+apps&f=json&t=microblogs&lang=fr"); $resArr = array(); $resArr = json_decode($response); echo "<pre>"; print_r($resArr); echo "</pre>";  function get_web_page($url) {     $options = array(         CURLOPT_RETURNTRANSFER => true,   // return web page         CURLOPT_HEADER         => false,  // don't return headers         CURLOPT_FOLLOWLOCATION => true,   // follow redirects         CURLOPT_MAXREDIRS      => 10,     // stop after 10 redirects         CURLOPT_ENCODING       => "",     // handle compressed         CURLOPT_USERAGENT      => "test", // name of client         CURLOPT_AUTOREFERER    => true,   // set referrer on redirect         CURLOPT_CONNECTTIMEOUT => 120,    // time-out on connect         CURLOPT_TIMEOUT        => 120,    // time-out on response     );       $ch = curl_init($url);     curl_setopt_array($ch, $options);      $content  = curl_exec($ch);      curl_close($ch);      return $content; }

The crux of the solution is setting

CURLOPT_RETURNTRANSFER => true 

then

$response = curl_exec($ch); 

CURLOPT_RETURNTRANSFER tells PHP to store the response in a variable instead of printing it to the page, so $response will contain your response. Here's your most basic working code (I think, didn't test it):

// init curl object         $ch = curl_init();  // define options $optArray = array(     CURLOPT_URL => 'http://www.google.com',     CURLOPT_RETURNTRANSFER => true );  // apply those options curl_setopt_array($ch, $optArray);  // execute request and get response $result = curl_exec($ch);
