What potential issues can arise when using odbc_fetch_array in PHP, as seen in this forum thread?

When using odbc_fetch_array in PHP, one potential issue that can arise is that it may return false when there are no more rows to fetch, which can lead to an infinite loop if not properly handled. To solve this, you should check the return value of odbc_fetch_array and break out of the loop when it returns false. 

// Connect to the database
$conn = odbc_connect('DSN', 'username', 'password');

// Execute a query
$result = odbc_exec($conn, 'SELECT * FROM table');

// Fetch rows and loop through them
while ($row = odbc_fetch_array($result)) {
    // Process the row data
    // ...

    // Check if there are more rows to fetch
    if (!$row) {
        break; // Exit the loop if there are no more rows
    }
}

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