Answers for "php how to accept json"

how to receive json data in php

$data = json_decode(file_get_contents('php://input'), true);
print_r($data);
echo $data;

file_get_contents('php //input')

Actually php://input allows you to read raw POST data.

It is a less memory intensive alternative to $HTTP_RAW_POST_DATA and does not need any special php.ini directives.

php://input is not available with enctype="multipart/form-data".
