Create a new row every n cells in an HTML table

I have the following code:

for ($i = 0; $i < count($gallery); $i++)
{
    $temp = array();
    $temp = $gallery[$i];
    echo "<img src='". $temp->path . "' />";
}

Now this code prints the content in one row. I want to print only 3 per row and then create new row and print another 3 and so on. How can this be done?

EDIT: error

You can do

$n = 3;
echo "<table><tr>";
for($i=0; $i<count($gallery);$i++){
    $temp = array();
    $temp = $gallery[$i];
    echo "<td><img src='". $temp->path . "' /></td>";
    if($i % $n ==0 && $i!=0 ){
        echo "</tr><tr>";
    }
}
echo '</tr></table>';

Edit:

If you want to do it the "right" way - by building the syntactically correct HTML, you need to do:

$n = 3;
echo "<table><tr>"; 
$gallery_count = count($gallery);
for($i=0; $i<$gallery_count; $i++){
    $temp = array();
    $temp = $gallery[$i];
    echo "<td><img src='". $temp->path . "' /></td>";

    if($i != 0){
        if($i % $n == 0 && $i != $gallery_count-1){
            echo "</tr><tr>";
        }
        else{
            echo ""; //if it is the last in the loop - do not echo
        }
    }
}

//example - if the last 2 `td`s are  missing:
$padding_tds  = $gallery_count % $n;
if($padding_tds != 0 ){
    $k = 0;
    while($k < $padding_tds){
       echo "<td>&nbsp;</td>";
    }
}
echo '</tr></table>';
