What are the potential pitfalls when trying to access PHP array values dynamically in JavaScript?

When trying to access PHP array values dynamically in JavaScript, one potential pitfall is that JavaScript cannot directly access PHP variables or arrays since PHP is a server-side language and JavaScript is a client-side language. To overcome this, you can use AJAX to send a request to the server and retrieve the PHP array values in JSON format. Then, you can parse the JSON data in JavaScript to access the array values dynamically. 

<?php
// PHP code to retrieve array values
$array = array("apple", "banana", "cherry");
echo json_encode($array);
?>
```

```javascript
// JavaScript code to access PHP array values dynamically
$.ajax({
  url: 'your_php_file.php',
  type: 'GET',
  success: function(data) {
    var arrayValues = JSON.parse(data);
    console.log(arrayValues[0]); // Output: apple
  }
});
