How do I properly split a PATH variable in PHP?

问题

I want to split

$path = getenv('PATH');

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

回答1:

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

回答2:

Use the PATH_SEPARATOR constant.

回答3:

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

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

回答4:

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.
