I have something like this and when a person checked a checkbox and then click the button Save, it would save the checked box and the next time the person see this table it would appear the table with all the checkboxs that the person checked or unchecked last time. How can I do that?

The months are in one array, check my code:

<?php

$results = mysql_query("SELECT * FROM utilizadores");

$month = array("January","February","March","April","May","June","July","August","September","October","November","December");

echo '<form id="form" method="post" action="">';
echo '<table border="1" align="center">';
echo '<tr class="d0">';
echo '<td align="center" height="30" width="400"><strong>Nome</strong></td>';
for($i=0;$i<=11;$i++)
{
echo '<td align="center" width="80"><strong>'.@$month[$i].'</strong></td>';
}
echo '</tr>';
$rowColors = Array('#ffffff','#ffffcc'); $c= 0;
while($row = mysql_fetch_array($results)) {

echo '<tr style="background-color:'.$rowColors[$c++ % count($rowColors)].';">';
echo '<td align="center" height="30" width="400">' . $row['nome'] . "</td>";
for($i=0;$i<=11;$i++)     {     
echo '<td align="center" width="80"><input type="checkbox" name="asd" /></td>';
}
}
echo "</tr>";
echo "</table>";
echo "<br>";
echo '<input name="submit" type="submit" value="Save" />';
echo '</form>';

?>
