Question

我正在尝试获取当前已登录用户的用户名，以便执行诸如在欢迎屏幕上显示用户名之类的操作。我使用php将用户连接到oracle11g数据库，但出现错误*注意：未定义的变量：第88行的C：\ xampp \ htdocs \ CamtelWork \ eBusiness \ index.php中的dbuser

注意：未定义的索引：在第88行的C：\ xampp \ htdocs \ CamtelWork \ eBusiness \ index.php中* 我已经定义了变量，但是我不知道该如何解决这个问题。

这是我的代码

login.php

<?php

header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");    // Date in the past
header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
                                                      // always modified
header ("Cache-Control: no-cache, must-revalidate");  // HTTP/1.1
header ("Pragma: no-cache");

session_start();
$uri = $_SERVER['PHP_SELF'] . "?" . SID;
if( isset($_POST['dbuser']) ) {
  $dbuser = $_POST['dbuser'];
}
if( isset($_POST['pass']) ) {
  $pass = $_POST['pass'];
}
?>

<title>Oracle in PHP test page</title>


<?php
// have username and password been passed from a form?
if ( isset($dbuser) && isset($pass) ) {
  // try to connect to Oracle with user and password supplied
        $conn = oci_connect($dbuser, $pass, 'localhost/orcl');


  if (!$conn) {
      $e = oci_error();
      echo htmlentities($e['dbuser'], ENT_QUOTES);
    unset($dbuser); unset($pass);
  }
}

?>
