no need to use http_build_query() khổng lồ handle parameters; just pass the array to lớn CURLOPT_POSTFIELDS is enough. – Raptor Atruyền thông quảng cáo 5 "16 at 3:13
Raptor providing array directly to lớn CURLOPT_POSTFIELDS actually curl makes slightly different type of POST. (Expect: 100-continue) – Oleg Popov Atruyền thông quảng cáo 14 "16 at 4:49
Also if value of CURLOPT_POSTFIELDS is an array, the Content-Type header will be phối lớn multipart/form-data instead of application/x-www-form-urlencoded. – Chloe Jul 21 "16 at 2:34
Using CURLOPT_RETURNTRANSFER means that curl_exec will return the response as a string rather than outputting it. – bnp887 Dec 28 "16 at 14:27
I suggest using true instead of 1 for CURLOPT_POST. – FluorescentGreen5 Aug 19 "17 at 8:53

// set post fields $post = < "username" => "user1", "password" => "passuser1", "gender" => 1, >; $ch = curl_init(""); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); // execute! $response = curl_exec($ch); // cđại bại the connection, release resources used curl_close($ch); // vì anything you want with your response var_dump($response);

Object oriented

return string *
throws RuntimeException On cURL error */ public function __invoke(array $post) curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); $response = curl_exec($ch); $error = curl_error($ch); $errno = curl_errno($ch); if (is_resource($ch)) if (0 !== $errno) return $response; } }


// create curl object $curl = new MyAppHttpCurlPost(""); try catch (RuntimeException $ex)

Side note here: it would be best lớn create some kind of interface called AdapterInterface for example with getResponse() method & let the class above sầu implement it. Then you can always swap this implementation with another adapter of your lượt thích, without any side effects to your application.
