When submitted this will create an array in PHP.
This is the output of a test run
Array
(
[0] => 3124
[3] => 45
[4] => 6756
)
Notice the indexes.
while (list ($key, $val) = each ($temp)) {
echo "$key => $val<br />\n";
}

Must be whitout coffee, but don't see the point.
The passing of check boxes comes from the fact of selecting them or not.
I tried to insert your code and got nowere. How do you see if in between
those boxes, one in the middle is set ?

Try this
<?
$i = 0;
echo '<form>';
echo '<input type="checkbox" name="temp['.$i++.']" value="3124">';
echo '<input type="checkbox" name="temp['.$i++.']" value="6345">';
echo '<input type="checkbox" name="temp['.$i++.']" value="456243">';
echo '<input type="checkbox" name="temp['.$i++.']" value="45">';
echo '<input type="checkbox" name="temp['.$i++.']" value="6756">';
echo '<input type="checkbox" name="temp['.$i++.']" value="4567">';
echo '<input type="submit" name="submit" value="test">';
echo '</form>';
//Then in PHP whether the box is checked or not your indexes are
correct.
print_r($temp);
?>

Take this for an example :
This script fills part of a form with checkboxes named C1,C2, ect
$cnt=0;
for ($i=1;$i<=$n_alunos;$i++) {
if ($cnt==0) {
print "<tr>";
}
print "<td><input type=\"checkbox\" name=\"C$i\" value=\"on\">Aluno
$i</td>";
$cnt++;
if ($cnt==$colunas) {
print "</tr>";
$cnt=0;
}
}
This script receives the result from the previous form, and checks
wether checkbox C2 is set or not
if (!empty($_POST['C2'])) {
$b = $_POST['C2'];
}
else {
$b = "vazio";
}
An example ...
