static ilFileUtils::makeDirParents ( string $a_dir )

Create a new directory and all parent directories.

Creates a new directory and inherits all filesystem permissions of the parent directory If the parent directories doesn't exist, they will be created recursively. The directory name NEEDS TO BE an absolute path, because it seems that relative paths are not working with PHP's file_exists function.

Parameters

string $a_dir The directory name to be created public

Returns: bool
