Layout of mySQl query

Well thanks a lot man!
Only thing i cannot seem to
grasp yet is that !$column is the first, and then
you close it when it's not the first anymore.
To me this would seem like it would only give one collumn.

Apparently i'm mistaken. But why? :s

Greetings

## start the table
echo '<table class="search_result" summary="search result">';

## initialize control variable
## $control will either be 0 or 1
## 0 means we're about to output the first column
## 1 means we're about to output the second column
$column = 0;

## for every record selected
while ($row = mysql_fetch_array($result)) {

## start a table row if it is the first column
if (!$column) echo '<tr>';
## print the data
echo '<td>', $row['whatever'], '</td>';
## end the row if it is not the first column
if ($column) echo '</tr>';

## swap between 1 and 0 every time this line executes
$column = !$column;
}

## if there were an odd number of records selected we will
## be left with an empty last cell -- fill it
if ($column) echo '<td>(empty cell)</td></tr>';

## end the table
echo '</table>';

Open the row on the first column, close it on the second -- just like
you say :-)


Compare these two versions between themselves and my original version

with $column being 1 and 2: with $column being 0 and 1:


$column = 1; $column = 0
loop() { loop() {
if ($column == 1) echo '<tr>'; if ($column == 0) echo '<tr>';
echo '<td>...</td>'; echo '<td>...</td>';
if ($column == 2) echo '</tr>'; if ($column != 0) echo '</tr>';
$column += 1;
if ($column == 3) $column = 1; $column = 1 - $column;
} }
