Save current page as HTML to server

Solution 1:

If you meant saving the output of a page in a file, you can use buffering to do that. The function you need to use are ob_start and ob_get_contents.

<?php
// Start the buffering //
ob_start();
?>
Your page content bla bla bla bla ...

<?php
echo '1';

// Get the content that is in the buffer and put it in your file //
file_put_contents('yourpage.html', ob_get_contents());
?>

This will save the content of the page in the file yourpage.html.

Solution 2:

I think we can use Output Control Functions of PHP, you can use save the content to the variable first and then save them to the new file, next time, you can test it the html file exists, then render that else re-generate the page.

<?php
$cacheFile = 'cache.html';

if ( (file_exists($cacheFile)) && ((fileatime($cacheFile) + 600) > time()) )
{
    $content = file_get_contents($cacheFile);
    echo $content;
} else
{
    ob_start();
    // write content
    echo '<h1>Hello world to cache</h1>';
    $content = ob_get_contents();
    ob_end_clean();
    file_put_contents($cacheFile,$content);
    echo $content;
}
?>

Solution 3:

Use JavaScript to send document.getElementsByTagName('html')[0].innerHTML as hidden input value or by ajax to the server side. This is more useful than output buffering if the content is afterwards traversed/modified by JavaScript, which the server side might not have any notion about.
