How can a PHP array be converted into a JavaScript array effectively?

To convert a PHP array into a JavaScript array effectively, you can use JSON encoding. This involves encoding the PHP array into a JSON string using `json_encode()` in PHP, and then decoding this JSON string into a JavaScript array using `JSON.parse()` in JavaScript.

<?php
// Sample PHP array
$phpArray = array("apple", "banana", "cherry");

// Encode PHP array into JSON string
$jsonArray = json_encode($phpArray);
?>

<script>
// Decode JSON string into JavaScript array
var jsArray = JSON.parse('<?php echo $jsonArray; ?>');

// Access and display JavaScript array elements
console.log(jsArray);
</script>
