What are the potential pitfalls of using odbc_fetch_array() in a PHP loop when retrieving data from a database?

Using odbc_fetch_array() in a loop can potentially lead to memory issues if the result set is large, as it fetches the entire row as an array each time. To solve this issue, you can fetch the row as needed and process it before fetching the next row in the loop. 

// Connect to the database
$conn = odbc_connect($dsn, $user, $password);

// Execute the query
$result = odbc_exec($conn, $query);

// Fetch and process rows one by one
while ($row = odbc_fetch_array($result)) {
    // Process the row here
    // Example: echo $row['column_name'];
}

// Close the database connection
odbc_close($conn);
