<?
$fn = 'test.gif';
echo preg_replace('/(.+?)(\..+?)/', '\1a\2', $fn);
?>
This script will output 'testa.gif'
now how can i make it produce 'test1.gif' ?
if i replace the: '\1a\2' with '\11\2' it will understand to replace with
occurence number 11 !
How can i escape the 2nd '1' so it is considered as a string an not another
number.
