Warning about HTTP RAW POST DATA being deprecated

Question

I switched to PHP 5 6 0 and now I get the following warning everywhere   Deprecated  Automatically populating  HTTP RAW POST DATA is deprecated and will be removed in a future version  To avoid this warning set  always populate raw post data  to  -1  in php ini and use the php   input stream instead  in Unknown on line 0  Warning  Cannot modify header information - headers already sent in Unknown on line 0   Fine  I rely on some deprecated feature  Except that I don t    I haven t ever used this variable in any of my scripts  To be honest I had no idea it even exists  phpinfo   shows that I have always populate raw post data set to 0  disabled   So what is going on    I don t want to  avoid the warning  by setting this value to -1  This will just hide the warning  and I ll still have deprecated configuration  I want to solve the problem at its source and know why PHP thinks that HTTP RAW POST DATA populating is turned on

Unfortunately  this answer here by  EatOng is not correct  After reading his answer I added a dummy variable to every AJAX request I was firing  even if some of them already had some fields  just to be sure the error never appears   But just now I came across the same damn error from PHP  I double-confirmed that I had sent some POST data  some other fields too along with the dummy variable   PHP version 5 6 25  always populate raw post data value is set to 0   Also  as I am sending a application json request  PHP is not populating it to   POST  rather I have to json decode   the raw POST request body  accessible by php   input   As the answer by  rr- cites      0 off whatever  BC behavior  populate if content-type is not registered or request method is other than POST     Because the request method is for sure POST  I guess PHP didn t recognize like my Content-Type  application json request  again  why      OPTION 1   Edit the php ini file manually and set the culprit variable to -1  as many of the answers here suggest   OPTION 2   This is a PHP 5 6 bug  Upgrade PHP   OPTION 3   As  user9541305 answered here  changing the Content-Type of AJAX request to application x-www-form-urlencoded or multipart form-data will make PHP populate the   POST from the POSTed body  because PHP likes recognizes those content-type headers      OPTION 4  LAST RESORT  Well  I did not want to change the Content-Type of AJAX  it would cause a lot of trouble for debugging   Chrome DevTools nicely views the POSTed variables of JSON requests    I am developing this thing for a client and cannot ask them to use latest PHP  nor to edit the php ini file  As a last resort  I will just check if it is set to 0 and if so  edit the php ini file in my PHP script itself  Of course I will have to ask the user to restart apache  What a shame   Here is a sample code    lt  php  if ini get  always populate raw post data       -1            Get the path to php ini file      iniFilePath   php ini loaded file            Get the php ini file content      iniContent   file get contents  iniFilePath           Un-comment  if commented  always populate raw post data line  and set its value to -1      iniContent   preg replace     s    s always populate raw post data s   s     im    always populate raw post data   -1    iniContent           Write the content back to the php ini file     file put contents  iniFilePath   iniContent           Exit the php script here        Also  write some response here to notify the user and ask to restart Apache   WAMP   Whatever      exit

It turns out that my understanding of the error message was wrong  I d say it features very poor choice of words  Googling around shown me someone else misunderstood the message exactly like I did - see PHP bug  66763   After totally unhelpful  This is the way the RMs wanted it to be   response to that bug by Mike  Tyrael explains that setting it to  -1  doesn t make just the warning to go away  It does the right thing  i e  it completely disables populating the culprit variable  Turns out that having it set to 0 STILL populates data under some circumstances  Talk about bad design  To cite PHP RFC      Change always populate raw post data INI setting to accept three values instead of two          -1  The behavior of master  don t ever populate  GLOBALS HTTP RAW POST DATA      0 off whatever  BC behavior  populate if content-type is not registered or request method is other than POST      1 on yes true  BC behavior  always populate  GLOBALS HTTP RAW POST DATA        So yeah  setting it to -1 not only avoids the warning  like the message said  but it also finally disables populating this variable  which is what I wanted

If you are using WAMP      you should add or uncomment the property always populate raw post data in php ini and set its value to -1  In my case php ini is located in   C  wamp64 bin php php5 6 25 php ini       but if you are still getting the warning  as I was       You should also set always populate raw post data   -1 in phpForApache ini       C  wamp64 bin php php5 6 25 phpForApache ini      If you can t find this file  open a browser window and go to       http   localhost  phpinfo 1      and look for the value of Loaded Configuration File key  In my case the php ini used by WAMP is located in       C  wamp64 bin apache apache2 4 23 bin php ini  symlink to C  wamp64 bin php php5 6 25 phpForApache ini    Finally restart WAMP  or click restart all services

For anyone still strugling with this problem after changing the php init as the accepted answer suggests  Since the error ocurs when an ajax petition is made via POST without any parameter all you have to do is change the send method to GET   var xhr     ajax      url   url     type   GET      dataType   html      timeout  500        Still an other option if you want to keep the method POST for any reason is to add an empty JSON object to the ajax petititon   var xhr     ajax      url   url     type   POST      data   name  emtpy petition data   value   empty      dataType   html      timeout  500

I experienced the same issue on nginx server  DigitalOcean  - all I had to do is to log in as root and modify the file  etc php5 fpm php ini   To find the line with the always populate raw post data I first run grep   grep -n  always populate raw post data  php ini   That returned the line 704  704  always populate raw post data   -1   Then simply open php ini on that line with vi editor   vi  704 php ini   Remove the semi colon to uncomment it and save the file  wq  Lastly reboot the server and the error went away

I got this error message when sending data from a html form  Post method   All I had to do was change the encoding in the form from  text plain  to  application x-www-form-urlencoded  or  multipart form-data   The error message was very misleading

User · Answer

Been awhile until I came across this error  Put up my answer for anyone who may stumble upon this issue   The error only means that you are sending an empty POST request  This error is commonly found on HTTPRequests with no parameters passed  To avoid this error  you can always add a parameter to the POST without changing the php ini   Like     post URL HERE       addedvar    anycontent        function d          doAnyHere d               json    or  html   text
