How can developers ensure smooth communication between PHP and JavaScript when handling strings?

To ensure smooth communication between PHP and JavaScript when handling strings, developers can use JSON encoding and decoding. By encoding PHP strings into JSON format and then decoding them in JavaScript, data can be easily passed between the two languages without any issues. 

<?php
// PHP code to encode a string into JSON format
$string = "Hello, world!";
$json_string = json_encode($string);
?>

<script>
// JavaScript code to decode the JSON string
var jsonString = <?php echo $json_string; ?>;
var decodedString = JSON.parse(jsonString);
console.log(decodedString); // Output: Hello, world!
</script>
