How do you POST to a page using the PHP header function

Question

I found the following code on here that I think does what I want  but it doesn t work    host    www example com    path     path to script php    data    data1 value1 amp data2 value2    data   urlencode  data    header  POST  path HTTP 1 1 r n    header  Host   host r n    header  Content-type  application x-www-form-urlencoded r n    header  Content-length      strlen  data      r n    header  Connection  close r n r n    header  data     I m looking to post form data without sending users to a middle page and then using JavaScript to redirect them  I also don t want to use GET so it isn t as easy to use the back button   Is there something wrong with this code  Or is there a better method   Edit I was thinking of what the header function would do  I was thinking I could get the browser to post back to the server with the data  but this isn t what it s meant to do  Instead  I found a way in my code to avoid the need for a post at all  not breaking and just continuing onto the next case within the switch

In addition to what Salaryman said  take a look at the classes in PEAR  there are HTTP request classes there that you can use even if you do not have the cURL extension installed in your PHP distribution

The answer to this is very needed today because not everyone wants to use cURL to consume web services  Also PHP does allow for this using the following  code  function get info          post data   array           test    gt   foobar            okay    gt   yes            number    gt  2                Send a request to example com      result    this- gt post request  http   www example com     post data        if   result  status       ok                Print headers         echo  result  header             echo   lt hr   gt                print the result of the whole request          echo  result  content               else           echo  A error occured       result  error              function post request  url   data   referer               Convert the data array into URL Parameters like a b amp foo bar etc       data   http build query  data           parse the given URL      url   parse url  url        if   url  scheme       http             die  Error  Only HTTP request are supported                    extract host and path       host    url  host         path    url  path            open a socket connection on port 80 - timeout  30 sec      fp   fsockopen  host  80   errno   errstr  30        if   fp               send the request headers          fputs  fp   POST  path HTTP 1 1 r n            fputs  fp   Host   host r n             if   referer                    fputs  fp   Referer   referer r n             fputs  fp   Content-type  application x-www-form-urlencoded r n            fputs  fp   Content-length     strlen  data     r n            fputs  fp   Connection  close r n r n            fputs  fp   data             result               while  feof  fp                    receive the results of the request              result    fgets  fp  128                       else           return array               status    gt   err                error    gt    errstr   errno                            close the socket connection      fclose  fp           split the result header from the content      result   explode   r n r n    result  2         header   isset  result 0      result 0             content   isset  result 1      result 1                return as structured array      return array           status    gt   ok            header    gt   header           content    gt   content

The header function is used to send HTTP response headers back to the user  i e  you cannot use it to create request headers   May I ask why are you doing this  Why simulate a POST request when you can just right there and then act on the data someway  I m assuming of course script php resides on your server   To create a POST request  open a up a TCP connection to the host using fsockopen    then use fwrite   on the handler returned from fsockopen   with the same values you used in the header functions in the OP  Alternatively  you can use cURL
