php://input is empty on server but it work on localhost

Question

I am trying to make a PUT request with the following, and it works just fine on localhost but it show empty once I try to run it on my domain. I have checked that PHP versions are the same on both localhost and shared server. I checked the and made sure that allow_url_fopen=On. Basically this is the part that does not work. I am trying to get the body of the PUT request from the 'php://input' with the following parse_str(file_get_contents('php://input'), $_PUT); and it returns empty. Moreover when I check to see if the file exists file_exists('php://input'), it says the file does not exists.

I read that these are called wrappers. I have tried reading from different variables and files but it still does not work.

What does `echo file_get_contents('php://input') ` give you? Maybe the string is just not parseable as you expect? — jaswrks, Nov 09 '17 at 17:38
Possible duplicate of [file\_get\_contents("php://input") showing null when var\_dump](https://stackoverflow.com/questions/32175002/file-get-contentsphp-input-showing-null-when-var-dump) — dsadnick, Nov 09 '17 at 17:40
@jaswrks file_get_contents('php://input') echoes null. so I don't believe is a parsing problem — Gacci, Nov 09 '17 at 18:01
@dsadnick it is not a duplicate 1) I am actually making a post. 2) Allow url_encode_include is set 3) It works on localhost — Gacci, Nov 09 '17 at 18:03
What does $args = array(); parse_str(file_get_contents('php://input'), $args); var_dump( $args ); output? — Jesse Schokker, Nov 09 '17 at 18:09
How does your PUT request look? Are you sure it's not being blocked by CORS? — Jesse Schokker, Nov 09 '17 at 18:22
Are you running any other PHP framework or library that might be reading `file_get_contents('php://input')` before you do? I believe it can only be read once. — jaswrks, Nov 09 '17 at 18:24
@JesseSchokker I don't believe it is blocked by CORS as it does not show any message regading a problem with that. I have edited my answer so you can see my ajax requets — Gacci, Nov 09 '17 at 18:55
I am also facing same issue, JSON post works on localhost and does not work on server (cpanel). Any suggestions? — user1710989, Aug 03 '19 at 11:18
