POST information received from forms

can PHP access it without names?

[david752]

The $_POST variable can be used in PHP to get a specific
field of a form sent using the POST method, by name:

$_POST["name"]

This is an associative array. A direct array reference
such as $_POST[0] always returns an empty string.

Is there any way to get a raw array of POST fields that
can be scanned without knowing their names beforehand,
just as GET fields can be scanned?

David,
This is a user entry from the online PHP manual (search "predefined variables").

$GLOBALS["HTTP_RAW_POST_DATA"] contains the raw POSTed data from a request. Also available (obviously) as $HTTP_RAW_POST_DATA in the global scope.

[david752]

This global variable is not always supported. My Apache does not support it.

However, the following code is also from the PHP Manual and seems to answer the question nicely.

echo "Values submitted via POST method:<br>";
reset ($HTTP_POST_VARS);
while (list ($key, $val) = each ($HTTP_POST_VARS))
{
echo "$key => $val<br>";
}
