Error on line 4?

Hi,

I downloaded the plugin, pasted my code in, and there is an error: Parse error: syntax error, unexpected ‘if’ (T_IF) in /home/content/a2pnexwpnas01_data01/13/3468913/html/wp-content/plugins/insert-php/insert_php.php(48) : eval()’d code on line 4.

Here is my code:
[insert_php]
$db = new mysqli(‘ip’, ‘user’, ‘password’, ‘database’);
 
if($db->connect_errno > 0){
    die(‘Unable to connect to database [‘ . $db->connect_error . ‘]’);
}
$sql = “SELECT * FROM banlist ORDER BY banTime DESC”;
 
if(!$result = $db->query($sql)){
    die(‘There was an error running the query [‘ . $db->error . ‘]’);
}
 
function convertToHumanReadableTime($seconds)
{
    $ret = “”;
    if (empty($seconds))
    {
        return “Permanent”;
    }
    /*** get the days ***/
    $days = intval(intval($seconds) / (3600*24));
    if($days> 0)
    {
        $ret .= “$days days “;
    }
 
    /*** get the hours ***/
    $hours = (intval($seconds) / 3600) % 24;
    if($hours > 0)
    {
        $ret .= “$hours hours “;
    }
 
    /*** get the minutes ***/
    $minutes = (intval($seconds) / 60) % 60;
    if($minutes > 0)
    {
        $ret .= “$minutes minutes “;
    }
 
    /*** get the seconds ***/
    $seconds = intval($seconds) % 60;
    if ($seconds > 0) {
        $ret .= “$seconds seconds”;
    }
 
    return $ret;
}
 
echo ‘<table class=”table table-striped”>
 <tr>
   <th>Character Name</th>
    <th>Ban Reason</th>
   <th>Ban Length</th>
    <th>Banned On</th>
 </tr>’;
 
while($row = $result->fetch_assoc()){
    echo ‘<tr>
   <td>‘.$row[‘charactername’].’</td>
    <td>’.$row[‘banMessage’].'</td>
   <td>’.convertToHumanReadableTime($row[‘banDuration’]).'</td>
    <td>’.date(“m/d/Y”, strtotime($row[‘banTime’])).'</td>
 </tr>’;
}
echo ‘</table>’;
