php for循环跳过两位

Question

I have a function in php that builds an html string for a table so at inside I have a for loop

for ($counter = 0; $counter<10; $counter++){
  $htmlString .= code for table row here;
}

The for loop only makes 5 rows and i even printed out the value of $counter and it says: 0, 2, 4, 6, 8

I have never seen this before and I can't think of any way to fix this other than changing the loop from 10 to 20 but I rather know what is causing this so I can fix it for good.

here is my full code for the function i pass in a row from a sql db:

function BuildNetworkString($Query){
        $NetworkHtml = "<table style='width:100%;'><tr>";
        $counter = 0;
        if($Query['FacebookID'] != '')
        {
            $NetworkHtml .= "<td style='width:10%; height:80px; text-align:center;'><a href='http://facebook.com/profile.php?id=" . $Query['FacebookID'] . "' class='black' title='Facebook - " . $Query['FacebookName'] . "'><img width='50px' src='Images/facebook.png'></a></td>";
            $counter+=1;
        }
        for ($counter; $counter<10; $counter++)
        {
            $NetworkHtml .= "<td style='width:10%; height:80px>&nbsp ;&nbsp;$counter</td>";
        }
        $NetworkHtml .= "</tr></table>";
        return $NetworkHtml;
    }

Try changing:

"<td style='width:10%; height:80px>&nbsp ;&nbsp;$counter</td>"

to:

"<td style='width:10%; height:80px'>&nbsp;&nbsp;$counter</td>"
