*/
function post_json_data($url, $data_string) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json; charset=utf-8',
'Content-Length: ' . strlen($data_string))
);
ob_start();
curl_exec($ch);
$return_content = ob_get_contents();
ob_end_clean();
$return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
return array('code'=>$return_code, 'result'=>$return_content);
}
$arr = array('a'=>'555','b'=>56454564);
dump(post_json_data('http://192.168.211.1/html/dump.php',json_encode($arr)));Note: When receiving data, you do not use $_POST, but
$content = file_get_contents('php://input');I believe you have mastered the method after reading the case in this article. For more exciting content, please pay attention to other related articles on the php Chinese website!
