php passing arguments in constructor - php

Question

Can anyone tell me why $Role is being ignored?
I am trying to pass an argument and it is always getting a null value, however, when I call the method the var_dump shows that the $Role is 2.
When I use the var_dump inside getListFromDB the $Role is being set to null.
Method getListFromDB()
function getListFromDB($tableName, $orderBy = 'Description', $where = null, $Role = null) {
DO_Common::debugLevel(0);
if (empty($tableName) || empty($orderBy))
throw new Exception("tableName and orderBy cannot be left empty");
var_dump($Role);
if (!empty($Role))
{
echo "here";
if ($Role === 2)
{
if ($tableName == 'AssetTypes')
{
$params = array('tableName' => 'AssetTypes',
'orderBy' => $orderBy,
'whereAdd' => 'Restricted = 1');
}
var_dump($params);
}
else
{
$params = array('tableName' => $tableName,
'orderBy' => $orderBy);
var_dump($params);
}
}
else
{
$params = array('tableName' => $tableName,
'orderBy' => $orderBy);
//var_dump($params);
}
if (!empty($where) && $table != 'AssetTypes') {
if (strpos(strtolower($where), 'flag') === false)
$where .= " AND Flag != " . fDELETED;
$params += array('whereAdd' => $where);
}
return DO_Common::toAssocArray($params);
}
How the method is being called:
$AssetTypesOptions = getListFromDB('AssetTypes', $Role);
Is there something I am missing here?

Answer 1

$Role is the fourth argument for the function but you are sending it as the second argument:
$AssetTypesOptions = getListFromDB('AssetTypes', 'Description', null, $Role);

Answer 2

You should call it as the fourth argument, like so:
getListFromDB("tablename", "some fancy description", "here", $Role);
I made them up obviously...
