How can errors be avoided when passing complex data structures like arrays between PHP and JavaScript?

Complex data structures like arrays can be passed between PHP and JavaScript by encoding them into JSON format before passing them. This ensures that the data is properly formatted and avoids errors that can occur due to differences in how arrays are handled in PHP and JavaScript. 

<?php
// Create a PHP array
$data = array('name' => 'John', 'age' => 30, 'city' => 'New York');

// Encode the array into JSON format
$json_data = json_encode($data);

// Pass the JSON data to JavaScript
echo "<script>var jsonData = $json_data;</script>";
?>
