剥离 PHP 数组的 JSON 编码

Question

我有一个使用 PHP 完成的 MySQL 查询，结果显示为数组。

$stmt = $mysqli->prepare("SELECT word FROM words ORDER BY RAND() LIMIT 5");
    $stmt->bind_result($words);

$stmt->execute();
$result = array();

while ($stmt->fetch()) {
    $w = new StdClass();
    $w->word = $words;
    array_push($result, $w);
}
$stmt->close();

然后，我使用 JSON 将数组传递给 javascript：

'words' : <?php echo json_encode($result); ?>,

但是输出是：

[{"word":"Watermelon"},{"word":"Orange"},{"word":"Melon"},{"word":"Cucumber"},{"word":"Apple"}]

有什么办法可以“剥离”“单词”并使其看起来像那样？

["Watermelon", "Orange", "Melon", "Cucumber", "Apple"]

提前谢谢你。

如果您的代码中不再需要对象数组 ($ws)，您可以将代码简化为：

$stmt = $mysqli->prepare("SELECT word FROM words ORDER BY RAND() LIMIT 5");
$stmt->bind_result($words);

$stmt->execute();
$result = array();

while ($stmt->fetch()) {
    array_push($result, $words);
}
$stmt->close();
