按钮的Onclick在HTML文件中工作，但在PHP文件中的HTML中不起作用

I'm very new to PHP, JS, and HTML so I hope you don't mind if the question is very trivial. So I basically have the following code, the onlick would work in a separate HTML file but it will not work if I put this in an echo of a PHP file or put it in a separate html block inside a PHP file.

button.html (this works) 

   <body>


        <p>Click the button to display the time.</p>

        <button onclick="getElementById('demo').innerHTML=Date()">What is the time?</button>

        <p id="demo"> </p>

    </body>

</html>

Here is the echo code:

button.php (doesn't work)

<?php
....
....
echo "

        <input type ='button' value = 'Date'  onclick = 'getElementById('demo')=Date();' /> 

        <p id='demo'> </p>

        "
?>

This is the HTML code inside PHP file that doesn't work.

button.php (doesn't work)

<?php>

?>

<html>
<body>

<p>Click the button to display the time.</p>

<button onclick="getElementById('demo').innerHTML=Date()">What is the time?</button>

<p id="demo"></p>

</body>
</html>

Any help would be appreciated!
