I want to sum each column on this table:
$docid = array(1, 2, 3, 4, 5);
$table = array('technology' => 1 , 'languange' => 2, 'town' => 3, 'gadget' => 4, 'smartphone' => 5);
echo "<table><tr><th>Token/Document</th>";
$count = count($table);
$doc_count = count($docid);
for($i=1; $i<=$count; $i++)
{
echo "<th>Doc.$i</th>";
}
foreach($table as $key=>$value)
{
echo "<tr><td>$key</td>";
for($i=0; $i<$doc_count;$i++)
{
$random = rand(1, 8);
echo "<td>$random</td>";
}
}
echo "</tr><td>RESULT</td>";
for($i=0; $i<$doc_count;$i++)
{
echo "<td>...(what should i use?)...</td>";
}
echo "</tr></table>";
Example:
=============================================
| Token/Document | Doc.1 | Doc.2 | Doc.3 | Doc.4 | Doc.5 |
=============================================
| technology...........|....5.....|....7.....|....4.....|....2.....|....1.....|
| language.............|....6.....|....8.....|....1.....|....5.....|....5.....|
| town....................|....5.....|....3.....|....2.....|....7.....|....6.....|
| gadget.................|....4.....|....1.....|....2.....|....4.....|....8.....|
| smartphone.........|....3.....|....7.....|....3.....|....1.....|....2.....|
=============================================
RESULT...............|....23....|....26....|....12....|....19....| 22....|
How to sum each column?
you could do something like this
$sum = 0;
for($i=0; $i<count($your_array); $i++)
{
//your codes
$sum += $values; //values to be summed up
}
echo "Total = ". $sum;
I hope this helps.
You need to store each $random
so you can total them in the final row.
$random = rand(1, 8);
$results[$i][] = $random; // store $random value in array
Then total the array using array_sum()
echo "<td>".array_sum($results[$i])."</td>";
$docid = array(1, 2, 3, 4, 5);
$table = array('technology' => 1 , 'languange' => 2, 'town' => 3, 'gadget' => 4, 'smartphone' => 5);
echo "<table><tr><th>Token/Document</th>";
$count = count($table);
$doc_count = count($docid);
for($i=1; $i<=$count; $i++)
{
echo "<th>Doc.$i</th>";
}
foreach($table as $key=>$value)
{
echo "<tr><td>$key</td>";
for($i=0; $i<$doc_count;$i++)
{
$random = rand(1, 8);
$results[$i][] = $random; // save in array for totaling
echo "<td>$random</td>";
}
}
echo "</tr><td>RESULT</td>";
for($i=0; $i<$doc_count;$i++)
{
echo "<td>".array_sum($results[$i])."</td>"; // total array using array_sum()
}
echo "</tr></table>";
