but people coding will commonly still use \

if you pass a ‘foo/bar/baz to your function, it will fail on win because it is trying to locate DIRECTORY_SEPARATOR with strrpos, which fails.

consider:
$pathname = str_replace(array(‘/’, ‘\\’), DIRECTORY_SEPARATOR, $pathname);

[Editor's Note: Good pick up. Fixed, thanks!]

<?php
function mkdirr($path)
// create a directory structure recursively
{
if(is_dir($path)) return true;
return mkdirr(dirname($path)) && @mkdir($path);
}
?>

The php manual states that:
“On Windows, both slash (/) and backslash (\) are used as path separator character. In other environments, it is the forward slash (/).”

A small change to this function will make this function work on both windows and *nix.

put this line at the top of the function:
$pathname = str_replace( “\\”, “/”, $pathname );

then where $next_pathname is set, use a “/” in place of the constant or variable

I made this change on my system and it works fine.

Thanks for a nice, very useful function.
