How can JSON be utilized to convert an array into a JSON object for transferring data between JavaScript and PHP?

To convert an array into a JSON object for transferring data between JavaScript and PHP, you can use the json_encode() function in PHP. This function will encode the array into a JSON string that can be easily parsed by JavaScript. Once the array is encoded into JSON, you can send it to JavaScript using AJAX or any other method of data transfer. 

<?php
$array = array("key1" => "value1", "key2" => "value2", "key3" => "value3");
$json = json_encode($array);
echo $json;
?>
