अगर आप पीडीओ के साथ ऐसा करना चाहते हैं तो यहां एक उदाहरण दिया गया है:
<?php
$dbh = new PDO("mysql:host=localhost;dbname=DBNAME", $username, $password);
$sql = "SELECT `id`, `title`, `time`, `start`, `backgroundColor`
FROM my_table";
$result = $dbh->query($sql)->fetchAll(PDO::FETCH_ASSOC);
//To output as-is json data result
//header('Content-type: application/json');
//echo json_encode($result);
//Or if you need to edit/manipulate the result before output
$return = [];
foreach ($result as $row) {
$return[] = [
'id' => $row['id'],
'title' => $row['title'],
'start' => $row['start'].' '.$row['time'],
'backgroundColor' => $row['backgroundColor']
];
}
$dbh = null;
header('Content-type: application/json');
echo json_encode($return);
?>
