How can JavaScript access an existing PHP array on a webpage?

To access an existing PHP array on a webpage using JavaScript, you can encode the PHP array into a JSON format using the json_encode() function in PHP. Then, you can output this JSON-encoded array in the webpage as a JavaScript variable. In your JavaScript code, you can then parse this JSON string back into a JavaScript object using JSON.parse(). 

<?php
$phpArray = array("apple", "banana", "cherry");
$jsonArray = json_encode($phpArray);
echo "<script>var jsArray = JSON.parse('$jsonArray');</script>";
?>
