REGEX help please

Hi,

I have 2 issues concerning regex:

1) change a string of:
number\number\number to number/number/number

for example:
2\0 to 2/0
3\1\2 to 3/1/2


2) change a string of:
numbers to digit/digit/digit

for example:
321 to 3/2/1
18 to 1/8

Please help me with the PHP code, I have tried many hours and I
couldn't get it to work, thanks.

You don't have to use regexp to do this. Try this:

$var = str_replace('\\', '/', $var);

assuming $var contains the string you want to change.
[color=blue]

This you can du with chunk_split():

$var = chunk_split($var, 1, '/');

This puts a '/' between every character in $var AND in the end. So if
you don't want the '/' in the end you can remove it with substr():

$var = substr($var, 0, -1);

Hope this is useful.
