我想对这张表的每一列求和:
$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>";
例子:
==============================================
| 令牌/文件 | 文件1 | 文件 2 | 文件3 | 文件 4 | 文件 5 |
==============================================
| 技术…………|……5……|…………7……|…………4……|………… 2……|……1……|
| 语言.........|....6....|....8....|....1....|.... ..5.....|....5....|
| 镇.........|....5....|....3....|....2. ....|....7....|....6....|
| 小工具..................|....4....|....1....|....2.... .|....4.....|....8....|
| 智能手机…………|……3……|…………7……|…………3……|…………1. ....|....2....|
==============================================
结果....|....23....|....26....|....12....|... .19....| 22....|
如何对每一列求和?
