Create rows and columns based on COUNT query - php

Question

Simple question I believe for anyone with minimal php skills (which I don't have sufficient amounts of haha)
$numrows = $retour['nb'] / 4;
echo $numrows;
echo "<table><tr>";
while ($callback = mysql_fetch_assoc($queryLocations2))
{
echo utf8_encode('<td><img src="/flags/' . strtolower($callback['loc_code']) . '.png" id="' . $callback['loc_id'] . '"><input type="checkbox" value="' . $callback['loc_url'] . '" />' . $callback['loc_city'] . ', ' . utf8_encode($callback['loc_state']) . '</td>');
}
echo "</tr></table>";
}
How would I go about presenting a table that will hold 4 results(4 columns) per row, based on the value of $numrows?
Thank you!

Answer 1

Output tr tags inside while loop:
$count = 0;
echo "<table>";
while ($callback = mysql_fetch_assoc($queryLocations2))
{
if ($count % 4 == 0)
echo '<tr>';
$count++;
echo utf8_encode('<td><img src="/flags/' . strtolower($callback['loc_code']) . '.png" id="' . $callback['loc_id'] . '"><input type="checkbox" value="' . $callback['loc_url'] . '" />' . $callback['loc_city'] . ', ' . utf8_encode($callback['loc_state']) . '</td>');
if ($count % 4 == 0)
echo '</tr>';
}
if ($count % 4 != 0)
{
// need to add missing td-s here
echo '</tr>';
}
echo "</table>";

$numrows = floor($retour['nb'] / 4);
echo $numrows;
$i=0;
echo "<table>";
while ($callback = mysql_fetch_assoc($queryLocations2))
{
if($i==4)
{
echo "<tr>";
echo utf8_encode('<td><img src="/flags/' . strtolower($callback['loc_code']) . '.png" id="' . $callback['loc_id'] . '"><input type="checkbox" value="' . $callback['loc_url'] . '" />' . $callback['loc_city'] . ', ' . utf8_encode($callback['loc_state']) . '</td>');
echo "</tr>";
$i=0;
}
$i++;
}
while ($i<4)
{
echo '<td></td>';
$i++;
}
echo "</table>";
}
//if numrows used for # of rows then use following
$count=0;
while ($callback = mysql_fetch_assoc($queryLocations2) && $count<=$numrows)
{
if($i==4)
echo "<tr>";
echo utf8_encode('<td><img src="/flags/' . strtolower($callback['loc_code']) . '.png" id="' . $callback['loc_id'] . '"><input type="checkbox" value="' . $callback['loc_url'] . '" />' . $callback['loc_city'] . ', ' . utf8_encode($callback['loc_state']) . '</td>');
if($i==4)
{
echo "</tr>";
$i=0;
$count++;
}
$i++;
}
while ($i<4)
{
echo '<td></td>';
$i++;
}
echo "</table>";
}
