Make a path work both on linux and Windows

Question

How can I make sure that this path:

new Zend_Log_Writer_Stream(APPLICATION_PATH . \'\\logs\\app.log\')  

works both on linux and on windows

Answer 1

if you want to communicate two or more app of your site, this trick will serve you much

$ Document_root = realpath ( \ filter_input ( INPUT_SERVER , ' DOCUMENT_ROOT '));

this is to convert the route you back real path and then just have to navigate between directories with the DIRECTORY_SEPARATOR without worrying about the operating system installed on your machine or web server
