Get output of page and do a final "parse" with PHP

I have a really long PHP/HTML page with lots of <?php tags all around the document. It's a really bad PHP code and I need to change some strings like XXX to ZZZ. I could try to change it in the code but it's so bad programmed and has around 7 thousand lines so I think I may try to find another alternative.

I just came out with this idea: is it possible to add a PHP code right at the bottom of the page in such a way that this PHP code "grabs" all the output code above and assign it to a variable so it can be manipulated and at the end it can be echoed?

Example:

<?php

balbalbla

?>

<div>BLABLA XXX</div>
....
blabla
<?php echo "blablXXXabla";>

..

Is it possible to add some PHP code right at the bottom of the code which grabs all of the previos "output" and change it?

You need to add code to the top and the bottom:

<?php
ob_start();

//code

$output = ob_get_clean();

$output = str_replace('XXX', 'ZZZ', $output);

echo $output;

This will start a buffer that captures all output with ob_start() and then after all output ob_get_clean() will get the contents and assign to the variable and then clear the buffer. Now just modify the contents of $output and display it.

See Output Buffering Control.
