Not Able to access MySQL data through php function - php

Question

I've added clients in clients.php sown on the following screenshot:
UPDATE: If I add new client from manange_sale page, The List Shows up soon after!
When I try to access them in another page through this function:
function get_client_info($client_id, $term) {
global $db;
$query = "SELECT * from clients WHERE client_id='".$client_id."'";
$result = $db->query($query) or die($db->error);
$row = $result->fetch_array();
return $row[$term];
}
It just does not show any clients list on that page:
Please help me resolve this issue.
Note: Same script is working perfectly on Online host but causing issues in localhost.
Rest of the client class:

Answer 1

What plattform do you use for the localhost? Online linux server and local a Windows machine? As it is run on the localhost, do you get warnings, notices or the sort? Or even a fatal?
<?
=$client->client_options($client->client_id);
?>
That looks odd. Why the '='?

Answer 2

Okay I finally figured how to make it work by the hint provided above. Actually this Syntax doesn't work in this case:
<?=$client->client_options($client->client_id);?>
The Solution is:
<?php echo $client->client_options($client->client_id); ?>
Thanks all anyway for brainstorming.
