How can PHP and JavaScript work together to achieve the desired outcome of hiding content under certain conditions?

To hide content under certain conditions using PHP and JavaScript, you can use PHP to generate JavaScript code that will handle the hiding/showing of the content based on the specified conditions. By outputting JavaScript code from PHP, you can dynamically control the visibility of the content on the client-side.

<?php
// PHP code to determine the condition
$condition = true;

// Output JavaScript code based on the condition
echo '<script>';
echo 'if (' . ($condition ? 'true' : 'false') . ') {';
echo 'document.getElementById("content").style.display = "none";';
echo '}';
echo '</script>';
?>
