What potential issues can arise when using PHP to generate HTML elements with embedded JavaScript code?

One potential issue that can arise when using PHP to generate HTML elements with embedded JavaScript code is the risk of syntax errors or conflicts between the PHP and JavaScript code. To solve this issue, it is recommended to properly escape the JavaScript code to ensure that it is treated as a string rather than executable code by PHP. 

<?php
// Example of generating a HTML element with embedded JavaScript code
$jsCode = 'alert("Hello, World!");';
echo '<button onclick="', htmlspecialchars($jsCode), '">Click me</button>';
?>
