How would you do this?

Anon

I am trying to figure out how to output an array into a table with 2 colums
and multiple rows like so:

Array( [0] => 24 [1] => 25 [2] => 34 [3] => 35 [4] => 36 [5] => 37 [6] => 38 [7] => 39 [8] => 40 [9] => 41 [10] => 42 [11] => 43 [12] => 44 [13] => 45)

<table>
<tr>
<td>$array[0]</td> <td>$array[1]</td>
</tr>
<tr>
<td>$array[2]</td> <td>$array[3]</td>
</tr>
<tr>
<td>$array[4]</td> <td>$array[5]</td>
</tr>
<tr>
<td>$array[6]</td> <td>$array[7]</td>
</tr>
<tr>
<td>$array[8]</td> <td>$array[9]</td>
</tr>
<tr>
<td>$array[10]</td> <td>$array[11]</td>
</tr>
<tr>
<td>$array[12]</td> <td>$array[13]</td>
</tr>
</table>

so after some_function()I should get this result.

24 25
34 35
36 37
38 39
40 41
42 43
44 45

Also it needs to be scalable so if the array grows or shrinks the table will accomadate

Any takers?

You could do something like this:

function some_function($someArray) {
echo "<table>";
for ($c=0; $c < count($someArray); $c=$c+2){
echo "<tr>";
echo "<td>$someArray[$c]</td>";
echo "<td>$someArray[$c+1]</td>";
echo "</tr>";
}

echo "</table>";

}

print ("<TABLE Border=1>");
$i=0;
while (list($key,$val)=each($array)) {
if ($i==0) print ("<TR>");
print ("<TD>$val</TD>");
$i++;
if ($i>1) {
print ("</TR>");
$i=0;
}
}
print ("</TABLE>");

Loop through the array and use a flag which is multiplicated with -1, so it switches between 1 and -1. If it's <0, echo '<tr><td>'.$arrayvalue.'</td>', otherwise '<td>'.$arrayvalue.'</td></tr>'.
Watch if at the end one column is missing and if, add '<td> </td>'.
That's it.

Using multiplication sounds awfully expensive just for a flag. Why not just flip between 0 and 1 with "$i=1-$i"?
Or true and false? "$i=!$i"

OK this function work great however if the array is an odd number of values then you loose the last value!!!!

How do you compensate for this?

Thanks

print ("<TABLE Border=1>");
$i=0;
while (list($key,$val)=each($array)) {
if ($i==0) print ("<TR>");
print ("<TD>$val</TD>");
$i++;
if ($i>1) {
print ("</TR>");
$i=0;
}
}
if ($i==1) print ("<TD></TD></TR>"); // compensate for odd # of keys
print ("</TABLE>");

Indeed, your script will then save some microseconds... ;-)

But if that's the kind of optimization tasks you're dealing with (because the larger are done), you are a lucky man!

I'm also thinking in terms of maintainability, clarity of purpose and code reuse (in situations where I do need the speed - whether on a busy site or an antique server!)
