How can PHP file system functions be used to manipulate and save echo output in HTML files?

To manipulate and save echo output in HTML files using PHP file system functions, you can use functions like file_put_contents() to write the echoed content to an HTML file. This allows you to dynamically generate HTML content and save it to a file for later use or display. 

<?php
// Start output buffering
ob_start();

// Echo your HTML content
echo "<h1>Hello, World!</h1>";

// Get the buffered output
$output = ob_get_clean();

// Save the output to an HTML file
file_put_contents('output.html', $output);

// Display a message if the file was saved successfully
if(file_exists('output.html')) {
    echo "Output saved to output.html";
} else {
    echo "Error saving output";
}
?>
