我需要制作一个 PHP 代码来从服务器获取数据,更新它并将更新的数据回显给用户。我是 PHP 的初学者,所以我不知道该怎么做。这是我现在拥有的代码。
那么如何更改代码以使其更新数据?
<?php
include 'config.php';
$ID = $_GET['ID'] ;
$sql = "select * from table where ID = \"$ID\" and condition = false ";
// This is what I need the table to be updated "Update table where where ID = \"$ID\" set condition = true" ;
try {
$dbh = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $dbh->query($sql);
$data = $stmt->fetchAll(PDO::FETCH_OBJ);
$dbh = null;
echo '{"key":'. json_encode($data) .'}';
} catch(PDOException $e) {
echo '{"error":{"text":'. $e->getMessage() .'}}';
}
?>
