If no baseDir is given it will try to add the structure to the existing root directory without replacing existing childs except those with equal names. File permissions are copied as well. Please note that file contents will only be copied if their file size does not exceed the given $maxFileSize which is 1024 KB.

Assumed $structure contains an array like this:

array('Core' = array('AbstractFactory' => array('test.php'    => 'some text content',
                                                'other.php'   => 'Some more text content',
                                                'Invalid.csv' => 'Something else',
                                          ),
                     'AnEmptyFolder'   => array(),
                     'badlocation.php' => 'some bad content',
               )
)

the resulting directory tree will look like this:

baseDir
\- Core
 |- badlocation.php
 |- AbstractFactory
 | |- test.php
 | |- other.php
 | \- Invalid.csv
 \- AnEmptyFolder

Arrays will become directories with their key as directory name, and strings becomes files with their key as file name and their value as file content.

If no baseDir is given it will try to add the structure to the existing root directory without replacing existing childs except those with equal names.

If the system does not support posix_getgid() the current group will be root (0).

If the system does not support posix_getuid() the current user will be root (0).

If the given content is null it will fall back to use the current root directory of the stream wrapper.

Returns given visitor for method chaining comfort.

If the name contains slashes, a new directory structure will be created. The returned directory will always be the parent directory of this directory structure.

Instead of vfsStreamWrapper::register(); vfsStreamWrapper::setRoot(vfsStream::newDirectory('root')); you can simply do vfsStream::setup() which yields the same result. Additionally, the method returns the freshly created root directory which you can use to make further adjustments to it.

Assumed $structure contains an array like this:

array('Core' = array('AbstractFactory' => array('test.php'    => 'some text content',
                                                'other.php'   => 'Some more text content',
                                                'Invalid.csv' => 'Something else',
                                          ),
                     'AnEmptyFolder'   => array(),
                     'badlocation.php' => 'some bad content',
               )
)

the resulting directory tree will look like this:

root
\- Core
 |- badlocation.php
 |- AbstractFactory
 | |- test.php
 | |- other.php
 | \- Invalid.csv
 \- AnEmptyFolder

Arrays will become directories with their key as directory name, and strings becomes files with their key as file name and their value as file content.

If no value is given only the current umask setting is returned.
