Works in the newest curl version. But this is still not implemented in the Windows version of PHP. Test script: --------------- <?php //generate string data function getStr($num) { $bstring = 'abcdefghijklmnopqrstuvxyz0123456789'; $str = ''; for($i = 0; $i < $num; $i++) { $str .= $bstring; } return $str; } $json = [ 'json1' => getStr(200), 'json2' => getStr(200), 'json3' => getStr(200), 'json4' => getStr(200), ]; $post = [ 'test1' => 'a', 'test2' => 'b', 'test3' => 'c', 'test4' => json_encode($json) //or use print_r or var_dump with return parameter ]; $ch = curl_init(); //send encoded json-data to service curl_setopt($ch, CURLOPT_URL, 'https://localhost/service.php'); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $result = curl_exec ($ch); curl_close($ch); var_dump($result); ?> service.php -------------------------------------------------------------------------------------- <?php //get the post data and write into request.log $result = file_put_contents('request.log', print_r($_REQUEST, true)); var_dump($result); //the content of $_REQUEST is wrong, json1 is repeated, content is cutted off //expected result: correct content in $_REQUEST ?> Expected result: ---------------- Correct post data in $_REQUEST.
