Re: tricky preg_replace and how to escape the \{occurencenumber}

probably this will be faster? $fn = str_replace(".gif", "1.gif", $fn); Lallous wrote:

<? $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. Elias
