replace character in value

[webbrowser]

Some of the variables I have do not work with images an example would be

1. 123456.jpg is ok
2. 123/456.jpg is not

I want to replace the / with a -

this is the line of code i am using but it doesn't work

$filename_new = str_replace('/','-',$filename);

Any help with this would be greatly appreciated.

How does it not work? It looks like it should work.

Sorry the above actually works. The problem was on another line.
