Hi
Regular expressions are tricky and can be very picky. If you have different input structures than the ones you provided, I cannot guarantee it to work with those other structures.
Hope it helps
<?php
// TEST SUBJECT STRINGS
$link1 = 'http://test.site.com/cat1/cat2/123.html';
$link2 = 'http://test.site.com/cat1/cat2/cat3/1.html';
// find this pattern
$pattern = '#^(.*/)(\d+)(\.html)$#';
// make these replacements
$replace = '\\1page-\\2.txt';
// regular expression preg_replace ...
print preg_replace( $pattern, $replace, $link1 );
print "\n<br>\n";
print preg_replace( $pattern, $replace, $link2 );
/** OUTPUT OF ABOVE TESTS
http://test.site.com/cat1/cat2/page-123.txt
http://test.site.com/cat1/cat2/cat3/page-1.txt
**/
?>
