What are the considerations for ensuring the proper execution and output of PHP scripts within JavaScript elements on a website?

When embedding PHP scripts within JavaScript elements on a website, it's essential to ensure that the PHP code is properly executed and the desired output is obtained. To achieve this, make sure to use PHP tags `<?php ?>` to enclose the PHP code within the JavaScript block. Additionally, consider using AJAX to fetch data from the server and dynamically update the webpage without reloading it. 

&lt;script&gt;
    var data = &lt;?php echo json_encode($data); ?&gt;;
    console.log(data);
&lt;/script&gt;
