Why is this code for uploading files not really uploading files

[KevinKiambe]

<?php
    // Connect to the database
    $dbLink = new mysqli('127.0.0.1', 'user', 'pwd', 'myTable');
    if(mysqli_connect_errno()) {
        die("MySQL connection failed: ". mysqli_connect_error());
    }
 
    // Query for a list of all existing files
    $sql = 'SELECT `id`, `name`, `mime`, `size`, `created` FROM `file`';
    $result = $dbLink->query($sql);
 
    // Check if it was successfull
    if($result) {
        // Make sure there are some files in there
        if($result->num_rows == 0) {
            echo '<p>There are no files in the database</p>';
        }
        else {
            // Print the top of a table
            echo '<table width="100%">
                    <tr>
                        <td><b>Name</b></td>
                        <td><b>Mime</b></td>
                        <td><b>Size (bytes)</b></td>
                        <td><b>Created</b></td>
                        <td><b>&nbsp;</b></td>
                    </tr>';
 
            // Print each file
            while($row = $result->fetch_assoc()) {
                echo "

                    </tr>";
            }
 
            // Close table
            echo '</table>';
        }
 
        // Free the result
        $result->free();
    }
    else

because this code is not supposed to upload files. check Atli's thread (PHP insights) for a full explanation of the code.
