如何在 php 中编写 javascript 警报？例如，如果我想在这种情况下弹出一个 javascript 警报，我该怎么做？
if(isset($_POST['downloadkey'])){
$key = $_POST['downloadkey'];
if($key != $data['download_key']){
echo 'Your key is wrong.';
echo '<script type="text/javascript"> alert(Your downlaod key is wrong, Please try again!);</script>';

You forgot to wrap string with quotes in alert .
您忘记在 alert 中用引号将字符串括起来。
"Your downlaod key is wrong, Please try again!" is a string
“您的下载密钥错误，请重试！” 是一个字符串
if(isset($_POST['downloadkey'])){
$key = $_POST['downloadkey'];
if($key != $data['download_key']){
echo 'Your key is wrong.';
echo '<script type="text/javascript"> alert("Your downlaod key is wrong, Please try again!");</script>';
}
}

You can do this by putting this alert into the onload of the body like so:
您可以通过将此警报放入主体的加载中来做到这一点，如下所示：
<body onload="alert('Your download key is wrong, Please try again!');">
...
</body>
