if (($ProjectId) && $KeyStatusId==’’ && $IssuedTo==’’ && $from==’’ && $to==’’){
$stmt = $this->conn->prepare(“SELECT KeyId, Name, KeyTypeId, KeyType, ProjectId, Project, KeyStatusId, KeyStatus, IssuedTo, IssuedToId, IssueDate, ReturnedTo, ReturnedToId, Returndate, Logdate, PurposeId, Purpose, Description, UserId, User, HookNo, Key1, Key2, Key3, Key4, Key5, Key6, Key7, Key8, Key9, Key10, Key11, Key12, LogTime, LogUserId, Loguser, SetNo, Property, KeysNO, Active, status, CallId, update_time FROM keymaster WHERE ProjectId IN (?)”) or trigger_error($stmt->error, E_USER_ERROR);

$stmt->execute();
}

Try with bindValue.
$stmt->bindValue(‘?’, $ProjectId);

You are binding to “s” something that is into round brackets, this will never work.
