I found two solutions to replace text in WordPress page. Both are working "almost" fine, except for a few issues:

Solution 1:

function callback($buffer) {
  // modify buffer here, and then return the updated code
  return $buffer;
}

function buffer_start() { ob_start("callback"); }

function buffer_end() { ob_end_flush(); }

add_action('wp_head', 'buffer_start');
add_action('wp_footer', 'buffer_end');

It is taken from:

WordPress filter to modify final html output and

http://www.dagondesign.com/articles/wordpress-hook-for-entire-page-using-output-buffering/

It works fine but it does not allow change of page title. Is there any way to change page title in above method?

The second solution I got from a popular plugin (code line no. 270): https://wordpress.org/plugins/real-time-find-and-replace/

function far_template_redirect() {
    ob_start();
    ob_start( 'far_ob_call' );
    //ob_end_flush(); fails here. I don't know why?
}

//Handles find and replace for public pages
add_action( 'template_redirect', 'far_template_redirect' );

It works fine, but many links online suggest that add_filter 'template_include' should be used instead of add_action 'template_redirect'. See:

https://markjaquith.wordpress.com/2014/02/19/template_redirect-is-not-for-loading-templates/ https://bbpress.trac.wordpress.org/ticket/1524

But if I try add_action 'template_redirect' instead of add_filter 'template_include', the text replace code works on some websites and breaks some other websites.

And people suggested that ob_end_flush() must be used with ob_start(), but the code fails if I include ob_end_flush in code after ob_start.

I like the solution 1, but is there any way to include headers and footers in it? Otherwise Solution 2 works for all websites, except that it does not have ob_end_flush and not recommended by many people, though a popular plugin uses it.
