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

[B.C. Lance]

probably this will be faster?

$fn = str_replace(.gif, 1.gif, $fn);

 $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.

Oh well,

I could have solved it w/ too many other methods, but how can I escape the
\{occurence} as in my case?

 and if you are gonna append '1' for all extension,

 try this:
 echo preg_replace('/(\..+?)/', '1$1', $fn);

hm...

this should work, notice the double quotes

echo preg_replace('/(.+?)(\..+?)/e', '\1.1.\2', $fn);
