What are some best practices for saving HTML output generated by PHP scripts as HTML files automatically?

When generating HTML output using PHP scripts, it can be useful to automatically save the output as HTML files for future reference or offline use. One way to achieve this is by using PHP's file handling functions to create and write the HTML output to a file. By doing this, you can easily save the generated HTML content without manual intervention.

<?php
// Generate HTML output
$html_output = "<html><head><title>Sample Page</title></head><body><h1>Hello, World!</h1></body></html>";

// Save HTML output to a file
$file_path = 'output.html';
$file_handle = fopen($file_path, 'w');
fwrite($file_handle, $html_output);
fclose($file_handle);

echo "HTML output saved to $file_path";
?>
