How to echo raw post message using php://input

Hi Everyone, I wrote a routine "postrawdata.php" for displaying HTTP raw request message. <?php $putdata = fopen( "php://input" , "rb" ); while(!feof( $putdata )) echo fread($putdata, 4096 ); fclose($putdata); ?> It works properly when using a socket program to post something to it. But submitting from a simple HTML below will make it dead, I have tested it under IE 6.0 and Netscape 7.0 , any suggestion is appreciate. <body> <form name="form1" method="post" action="postrawdata.php"> <input type="text" name="name" > <input type="submit" name="Submit" value="Submit"> </form> </body> Thanks, Willaim Hong
