Parsing of a POST drops duplicate variables unless those variables have "[]".  

It's a few lines in Perl to get it, but I need to stay inside PHP....

is there anywhere that the equivalent of thePerl $form field below:
  if ( $ENV{'REQUEST_METHOD'} eq "POST" ) {
  read(STDIN,$form, $ENV{'CONTENT_LENGTH'});
is available in a PHP session...

I need the whole unparsed line, so that I can manage transforming duplicates into an array.

I have a situation where a check-box coded by someone else I have no control over is sending multiple values with the same field name.   Code for parsing into HTTP_POST_VARS discards all but the last name value pair in the Parse stage because, unfortunately the field is not ending in "[]" in the FORM.


... thoughts.

this is by design. 

take a look at this (you'll have to edit it):

        function _QueryString()
        {
            $qsstr = '' ;
            $qsarr = array() ;
            $QS = strtr( $GLOBALS['HTTP_SERVER_VARS']["QUERY_STRING"] , array( '[' => '' , ']' => '' ) ) ;
            $QS = explode( '&' , $QS ) ;
            foreach( $QS as $q ) {
                $eq = strpos( $q , '=' ) ;
                if( false === $eq ) {
                    $var = $q ;
                    $val = '' ;
                } else {
                    $var = substr( $q , 0 , $eq  ) ;
                    $val = substr( $q , $eq+1 ) ;
                }
                if( isset( $qsarr[$var] ) ) {
                    $qsarr[$var] = array_merge( (array) $qsarr[$var] , array( $var => $val ) ) ;
                } else {
                    $qsarr[$var] = $val ;
                }
                $qsstr .= "$var=$val&" ;
            }
            $this->_QueryString = substr( $qsstr , 0 , -1 ) ;
            $this->QueryString = $qsarr ;
        }

open again, this won't work for POSTs...
thx to Zak.

$HTTP_RAW_POST_DATA or $_SERVER["HTTP_RAW_POST_DATA"] with 
the new superglobals is where POST data is. With that, 
cynic's example can be made to work with POST as well. 
Closing this.
