Redirect with POST data         param string  url URL      param array  post data POST data  Example  array  foo    gt   var    id    gt  123      param array  headers Optional  Extra headers to send      public function redirect post  url  array  data  array  headers   null         params   array           http    gt  array               method    gt   POST                content    gt  http build query  data                       if   is null  headers              params  http    header                 foreach   headers as  k   gt   v                 params  http    header        k   v n                        ctx   stream context create  params        fp    fopen  url   rb   false   ctx       if   fp            echo  stream get contents  fp           die          else              Error         throw new Exception  Error loading   url    php errormsg

You can t do this using PHP   As others have said  you could use cURL - but then the PHP code becomes the client rather than the browser   If you must use POST  then the only way to do it would be to generate the populated form using PHP and use the window onload hook to call javascript to submit the form   C

Yes  you can do this in PHP e g  in      Silex or Symfony3   using subrequest   postParams   array       email    gt   request- gt get  email         agree terms    gt   request- gt get  agree terms         subRequest   Request  create   register    POST    postParams   return  app- gt handle  subRequest  HttpKernelInterface  SUB REQUEST  false

Use curl for this  Google for  curl php post  and you ll find this  http   www askapache com htaccess sending-post-form-data-with-php-curl html   Note that you could also use an array for the CURLOPT POSTFIELDS option  From php net docs      The full data to post in a HTTP  POST  operation  To post a file  prepend a filename with   and use the full path  This can either be passed as a urlencoded string like  para1 val1 amp para2 val2 amp      or as an array with the field name as key and field data as value  If value is an array  the Content-Type header will be set to multipart form-data

A better and neater solution would be to use   SESSION   Using the session     SESSION  POST       POST    and for the redirect header request use   header  Location  http   www provider com process jsp id 12345 amp name John   true  307     307 is the http response code you can use for the redirection request with submitted POST values

I used the following code to capture POST data that was submitted from form php and then concatenate it onto a URL to send it BACK to the form for validation corrections  Works like a charm  and in effect converts POST data into GET data   foreach   POST as  key   gt   value        urlArray       key      value       urlString   implode   amp     urlArray    echo  Please  lt a href  form php    urlString    gt go back lt  a gt

A workaround wich works perfectly     In the source page   start opening a session and assign as many values as you might want  Then do the relocation with  header      lt  DOCTYPE html gt   lt html gt      lt head gt          lt  php            session start                 SESSION  val1     val1                              SESSION  valn     valn             header  Location  http  Page-to-redirect-to             gt      lt  head gt   lt  html gt    And then  in the targe page     lt  DOCTYPE html gt   lt  php     session start      gt   lt html gt               lt body gt           lt  php             if  isset   SESSION  val1     amp  amp       amp  amp  isset   SESSION  valn                       YOUR CODE HERE based on   SESSION  val1       SESSION  valn   values                         gt       lt  body gt   lt  html gt    No need of Javascript nor JQuery   Good luck

Another solution if you would like to avoid a curl call and have the browser redirect like normal and mimic a POST call   save the post and do a temporary redirect   function post redirect  url          SESSION  post data       POST      header  Location       url       Then always check for the session variable post data   if  isset   SESSION  post data             POST     SESSION  post data          SERVER  REQUEST METHOD      POST       unset   SESSION  post data         There will be some missing components such as the apache request headers   will not show a POST Content header   etc

Alternatively  setting a session variable before the redirect and test it in the destination url  can solve this problem for me

You have to open a socket to the site with fsockopen and simulate a HTTP-Post-Request  Google will show you many snippets how to simulate the request
