如何将结果从 php 转为 html<select>选项？

Question

i have a select option in index.html , i want to get result from mySQL via php, but how to get the result from php ,and add results to html automatically我在 index.html 中有一个选择选项，我想通过 php 从 mySQL 获取结果，但是如何从 php 获取结果，并自动将结果添加到 html

index.html:索引.html：

<form action="get.php" method="post" >
    <select>
    <option  class="rm" value="trap"><get results from php></option>
.............
    </select>
 </form>

If you could show me a working example which does that, or may be any similar idea, it would be good.如果您可以向我展示一个可以做到这一点的工作示例，或者可能是任何类似的想法，那就太好了。

I don't really understand what you mean.我真的不明白你的意思。 But did you mean something like this:但是你的意思是这样的吗：

<html>
<body>
<select>
<?php
$root = realpath($_SERVER["DOCUMENT_ROOT"]);
include "$root/config.php";

$something1 = "something1";
$something2 = "something2";

$stmt = $pdo->prepare('SELECT DISTINCT from_mysql FROM customers WHERE something1 = :something1 AND from_mysql != :something2 ORDER BY from_mysql');
$stmt->execute(array(':something1' => $something1, ':something2' => $something2));

$results = $stmt->fetchAll();

if (empty($results)) { 
    echo 'Error: Please contact technical support!'; 
} else {
foreach( $results as $row ) {
    echo "<option>".$row['from_mysql']."</option>";
}
}
?>
</select>
</body>
</html>

PS You'll have to use index. PS 你必须使用索引。 php php
