PHP OCI错误OCI\u按\u名称绑定\u

我一直在尝试让这个函数工作，因为它是我的在线商店的会话获取程序。它在oci\u bind\u by\u name行中不断出错。我想知道为什么会出现这种情况，以及这个问题的可能解决方案

function getSessionID($customerID)
{
    global $conn;

    $query = "SELECT SESSIONID FROM \"StrSession\" WHERE EMAIL = ':cid'";
    $sessInfo = oci_parse($conn, $query);

    oci_bind_by_name($sessInfo, ":cid", $customerID, 64);
    oci_execute($sessInfo);

    $row = oci_fetch_array($sessInfo);
    if ($row)
        return $row["SESSIONID"];
    else
        return null;
}

以下是我记录会话的方式：

function logSession($customerID)
{
    global $conn;

    // Is the customer already logged in? If so, log them out then log back in again.
    if (isLoggedIn($customerID))
        unlogSession($customerID);

    $sessionID = session_id();

    $bindVars = array(
        array("varname" => "sessionID", "bindname" => ":sid", "length" => 64),
        array("varname" => "customerID", "bindname" => ":cid", "length" => 64)
    );

    // Insert a new row into the session table with the session ID and customer ID
    $query = oci_parse($conn, "INSERT INTO \"StrSession\" VALUES(':sid', ':cid')");

    foreach ($bindVars as $field)
        oci_bind_by_name($query, $field["bindname"], ${$field["varname"]}, $field["length"]);

    if (DEBUG) echo "Query: $query\n";

    oci_execute($query);
}

最后，检查登录的方式如下：

    function checkLogin($username, $pass)
{
    global $conn;

    $passhash = md5($pass);

    $query = "SELECT \"EMAIL\" FROM \"StrCustomer\""
     . " WHERE \"USERNAME\" = '$username' AND \"PASSWORD\" = '$passhash'";
    $loginInfo = oci_parse($conn, $query);
    oci_execute($loginInfo);

    $row = oci_fetch_array($loginInfo);
    if ($row)
        return $row["EMAIL"];
    else
        return null;
}

不要在绑定变量周围加单引号。只需移除它们。这是您希望对select查询执行的操作：

$query = "SELECT SESSIONID FROM \"StrSession\" WHERE EMAIL = :cid";

对于插入查询：

$query = oci_parse($conn, "INSERT INTO \"StrSession\" VALUES(:sid, :cid)");

“不断出错”？请具体说明您看到的错误。当用户尝试登录时，他们不会被重定向到产品目录，而是会看到：ORA-01036 oci_bind_by_name非法变量/编号您是否需要在此处的表名周围或占位符周围加引号<代码>“插入到\“StrSession\”值（':sid'，':cid'）”嗯，试过了。没用。
