php://input fopen ok, file_get_contents not ok
Hi,
I need help on tis. I still can't resolve the issue of undefined index, HTTP_RAW_POST_DATA error. So I tried alternatively using php://input.
However, I could fopen php://input but couldn't access the contents of php://input.
My else statement would display echo "The file does not exist".
Another thing, how do I print out the contents of php://input?
Please advise. Thank you, Sally

Using apache server 1.3.31 and php 4.3.6

My coding is as below.
<?
//added NR
ob_start("ob_gzhandler");
//end added
include('connect.php');
include('convertgeom.php');
//$data = $GLOBALS["HTTP_RAW_POST_DATA"]; //orig

//if (!($fp = fopen("php://input", "rb")))
// die("couldn't open $fp");
//else
// {
// echo("ok");
// }
//fclose($fp);

if ($data=file_get_contents("php://input"))
echo "The file exists";
else {
echo "The file does not exist";
}

Hi , well both of these work for me on receiving POSTed XML stream..

PHP Code:
<?
$yaks = fopen('php://input','r');
echo fgets($yaks,1024);
fclose($yaks);
?>
PHP Code:
<?
echo $GLOBALS['HTTP_RAW_POST_DATA'];
?>

the php://input does not rely on php configuration so should work regardess.

With that in mind , I would perhaps be looking at the original data source , is it using POST? is it setting the relevant content-type etc ? , where is the data-stream coming from ?
