phinx init results in directory is not writable when path contains OneDrive

[MichaelMrt]

Problem

I tried to follow the Installation guide from the docs and couldn't get past
vendor/bin/phinx init

The Issue I got is:

In Init.php line 146:

  The directory "C:\path\to\myrepo" is not writable  


init [-f|--format FORMAT] [--] [<path>]

What I tried

After looking at line 146:
if (!is_writable($dirname)) {

I separately tested the is_writable() method in php
php -r "echo is_writable('C:\\path\\to\\myrepo') ? 'Writable' : 'Not writable';"
and the result was Not writable.

Then I tested creating a file and writing into it with php
php -r "if(file_put_contents('C:\\path\\to\\myrepo\\phpwritten.txt','test')) { echo 'Success'; } else { echo 'Error';
and it worked.

After some testing I found out the Onedrive part is making the is_writable() method return false.
C:\Users\myuser\OneDrive - company\myrepo

Workaround

After using a path without OneDrive in it everything worked.
Also removing line 146 lead to a successful creation of the phinx.php file

Maybe there is a way to fix this or add a note in the docs like in #116 ?

Thanks for the report. I think the solution here is to remove the check and then just rely on file_put_contents failing for really deciding if something isn't writable or not, maybe doing something like:

        if (file_put_contents($path, $contents) === false) {
            throw new RuntimeException(!is_writable($dirname) ? sprintf(
                'The directory "%s" is not writable',
                $dirname
            ) : sprintf(
                 'The file "%s" could not be written to',
                $path
            ));
        }

I doubt there should ever be a case where file_put_contents(...) works while !is_writable($dirname) where we're fine still doing the write regardless. I think having the error message around !is_writable($dirname) is still useful though, hence the ternary within the conditional.

If you want to make a PR, happy to look it over, otherwise I'll try to get something done next week sometime.
