我正在尝试使用 mysql 查询和 php 构建一个比较表。
我希望结果显示在列中,如下所示:
<table border="1" cellspacing="0" cellpadding="0">
<tr>
<td width="151" scope="col">product</td>
<td width="89" scope="col">product1</td>
<td width="78" scope="col">product2</td>
<td width="77" scope="col">product3</td>
</tr>
<tr>
<td>type</td>
<td>type2</td>
<td>type3</td>
<td>type5</td>
</tr>
<tr>
<td>size</td>
<td>size2</td>
<td>size1</td>
<td>size4</td>
</tr>
<tr>
<td>price</td>
<td>4.99</td>
<td>3.99</td>
<td>3.59</td>
</tr>
</table>
但我只能让表格显示结果 - 而不是行标题(即我希望第一列显示“产品”、“类型”、“尺寸”、“价格”。
我到目前为止的代码是
<?php
// query the database
$result = mysql_query($query_getproducts);
// cols we are interested in (from the SQL query)
$cols = array(
'product',
'type',
'size',
'price',
);
// initialize rotated result using cols
$rotated = array();
foreach($cols as $col) {
$rotated[$col] = array();
}
// fill rotated array
while(($row = mysql_fetch_assoc($result)) !== false) {
foreach($cols as $col) {
$rotated[$col][] = $row[$col];
}
}
// echo html
echo "<table border=1 width=473>";
echo "<tr>";
echo "</tr>";
foreach($rotated as $col => $values) {
echo "<tr>";
foreach($values as $value) {
echo "<td> " . htmlentities($value) . "</td>";
}
echo "</tr>";
}
echo "</table>";
?>
希望有人可以提供帮助。
