regexp help....

I am trying to use this :

preg_match("!^.(.*?)(/[^/]+){2}$!", $_SERVER['PHP_SELF'], $parent);
echo $parent[1];

Which in itself does work, and gives the name of the parent directory, when the {n} is changed, will give the child, and grandparent etc...

I am not trying to modify it to use realpath(getcwd()) instead of the PHP_SELF...

preg_match("!^.(.*?)(/[^/]+){2}$!", realpath(getcwd()), $parent);
echo $parent[1];

Now gives me nothing - due to the / slashes now being \ (on a windows box) - changing both / to \ doesn't work either.

But changing the {2} to {0} does give me everything - so I know I am on the right track. But my use of regexps is limited....

Any help - pointing in the right direction ?

Cheers,

Youd need to change [^/] to [^\]. Single backslash is a reserved character in PCRE (the escape character)

The code now becomes

preg_match("!^.(.*?)(\\\\\\\\[^\\\\\\\\]+){2}$!", realpath(getcwd()), $parent);
echo $parent[1];

Bingo - gets the result.... 😃

Agghh.. trying to get the proper code to show is a nightmare...

This forums regexp parser escapes things btw so remember to escape your escapes :p
