What are the potential pitfalls of converting a PHP multi-array into a JavaScript object literal?

Converting a PHP multi-array into a JavaScript object literal can lead to potential pitfalls such as losing the hierarchical structure of the multi-array and encountering syntax errors due to differences in array notation between PHP and JavaScript. To solve this issue, you can use the json_encode function in PHP to convert the multi-array into a JSON string, which can then be easily parsed in JavaScript to create an object literal. 

<?php
$multiArray = array(
    'key1' => array(
        'subkey1' => 'value1',
        'subkey2' => 'value2'
    ),
    'key2' => array(
        'subkey3' => 'value3',
        'subkey4' => 'value4'
    )
);

$jsonString = json_encode($multiArray);
echo "<script>var jsObject = JSON.parse('$jsonString');</script>";
?>
