How can developers ensure that PHP variables are properly passed and accessed in JavaScript functions for interactive web elements like image pop-ups?

To ensure that PHP variables are properly passed and accessed in JavaScript functions for interactive web elements like image pop-ups, developers can use PHP to echo the variables into JavaScript code within the HTML document. By embedding the PHP variables directly into the JavaScript functions, the values can be accessed and used dynamically. This approach allows for seamless communication between PHP and JavaScript, enabling interactive elements to display the correct data. 

<?php
$variable = "example";
?>

<script>
var jsVariable = "<?php echo $variable; ?>";

// Use jsVariable in JavaScript functions for interactive web elements
</script>
