What potential issues could arise when combining PHP and JS in this way?

One potential issue that could arise when combining PHP and JS in this way is that the two languages may not communicate effectively due to differences in syntax and execution environments. To solve this issue, you can use PHP to generate JavaScript code dynamically and pass data between the two languages using AJAX calls. 

<?php
// PHP code to generate JavaScript code dynamically
$data = array('name' => 'John', 'age' => 30);
echo '<script>';
echo 'var data = ' . json_encode($data) . ';';
echo '</script>';
?>

<script>
// JavaScript code to access data passed from PHP
console.log(data.name); // Output: John
console.log(data.age); // Output: 30
</script>
