            Bug ID: 54218
           Summary: POST value duplicated when passed to PHP
           Product: Apache httpd-2
           Version: 2.2.16
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: All
          Assignee: bugs@httpd.apache.org
          Reporter: sarciszewski@knights.ucf.edu
    Classification: Unclassified

Code:
<?
if(!empty($_POST)) {
  header("Content-Type: text/plain");
  echo file_get_contents('php://input');
  echo "\n=========================================================\n";
  var_dump($_POST); exit;
}
?>
This duplicates:
<form method="post" target="_blank">
    <input type="text" name="menu" value="Blah" />
    <input type="submit" />
</form>
<p>This doesn't:</p>
<form method="post" target="_blank">
    <input type="text" name="menu" value="Blah" />
    <input type="text" name="second" value="Second value" />
    <input type="submit" />
</form>

Output (first button):
menu=Blahmenu=Blah
=========================================================
array(1) {
  ["menu"]=>
  string(13) "Blahmenu=Blah"
}
Output (second button):
menu=Blah&second=Second+valuemenu=Blah&second=Second+value
=========================================================
array(2) {
  ["menu"]=>
  string(4) "Blah"
  ["second"]=>
  string(12) "Second value"
}
