How do I properly split a PATH variable in PHP?

Question

I want to split

$path = getenv(\'PATH\');

into its components. How do I determine the separator char in an os-dependent fashion?

Answer 1

I seem to remember that Windows will accept both forward- and back-slashes as a file-separator, so you may not have to worry about it.

Answer 2

Use the PATH_SEPARATOR constant.

Answer 3

I know this works for the include_path - not sure about getenv('PATH'):

$paths = split(PATH_SEPARATOR, getenv('PATH'));

Answer 4

You can use the PATH_SEPARATOR constant, then the DIRECTORY_SEPARATOR constant to split the path if needed. See Directory Predefined Constants
