What are the limitations of using document.write in PHP to output content in JavaScript?

Using document.write in PHP to output content in JavaScript is not recommended because it can cause issues with the order of execution and can lead to unexpected behavior. To solve this issue, it is better to separate PHP and JavaScript logic by using AJAX or by echoing JavaScript variables directly in the script tag. 

<?php
// PHP code to set JavaScript variable
$variable = "Hello, World!";
echo "<script>var jsVariable = '" . $variable . "';</script>";
?>
