我必须得到所有结果并推送到HTML表格,但现有的行必须合并为1行。
这是我的表
id domain php_version
-----------------------------
1 localhost 5.5.30
2 live 7.05
3 localhost 5.5.30
4 localhost 5.5.30
和输出html表的代码是:
// Prepare query
$stmt = $mysqli->prepare("SELECT * FROM domains ORDER BY domain ASC LIMIT 10");
// Execute the query
$stmt->execute();
// Bind Parameters
$stmt->bind_result($id, $domain, $php_version);
<?php while ($stmt->fetch()) : ?>
<tr class="row-id-<?php echo $id; ?>">
<td class="id"><?php echo $id; ?></td>
<td class="domain"><?php echo $domain; ?></td>
<td class="php_version"><?php echo $php_version; ?></td>
</tr>
<?php endwhile; ?>
输出如下:
我只想这样:
我只是想在一行/列中合并dublicated域的值
非常感谢!

首先从mysql中获取结果并将其转换为常规PHP数组(在我的代码中称为$ array),然后这个代码片段将执行您想要的操作:
function sort_by_php_version($a, $b)
{
if ($a["php_version"] == $b["php_version"]) {
return 0;
}
return ($a["php_version"] < $b["php_version"]) ? -1 : 1;
}
$array = [
["id"=>1, "domain"=>"localhost", "php_version"=>"5.5.30"],
["id"=>2, "domain"=>"live", "php_version"=>"7.05"],
["id"=>3, "domain"=>"localhost", "php_version"=>"5.5.30"],
["id"=>4, "domain"=>"localhost", "php_version"=>"5.5.30"],
];
usort($array, "sort_by_php_version");
$in_domain = null;
$output_array = array();
for ($i=0; $i<count($array); $i++)
{
$thisRow = $array[$i];
$domain = $thisRow["domain"];
if ($domain == $in_domain) {
$output_array[count($output_array) - 1]["php_versions"][] = $thisRow["php_version"];
} else {
$thisRow["php_versions"] = array($thisRow["php_version"]);
unset($thisRow["php_version"]);
$output_array[] = $thisRow;
$in_domain = $domain;
}
}
var_dump($output_array);

我认为我设法使用group_concat:
SELECT domain,
GROUP_CONCAT(DISTINCT php_version SEPARATOR '\n' ) php_versions,
...
FROM domains GROUP BY domain
