iterate over array
I can not for the life of me figure out how to iterate over this array

Code:
{
	'name1' =>	{
				'a' =>	[
						'one',
						'two',
					].
				'b' =>	[
						'three',
						'four',
					]
			},
	'name2' =>	{
				'a' =>	[
						'one',
						'two',
					].
				'b' =>	[
						'three',
						'four',
					]
			}
}

I want a for loop to iterate through the first element (name1 and name2 in my example) but I can't figure it out. Help please?

LINK(2) 							System Calls Manual							   LINK(2)

NAME

       link - make a hard link to a file

SYNOPSIS

       link(name1, name2)
       char *name1, *name2;

DESCRIPTION

       A hard link to name1 is created; the link has the name name2.  Name1 must exist.

       With hard links, both name1 and name2 must be in the same file system.  Unless the caller is the super-user, name1 must not be a directory.
       Both the old and the new link share equal access and rights to the underlying object.

RETURN VALUE

       Upon successful completion, a value of 0 is returned.  Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

       Link will fail and no link will be created if one or more of the following are true:

       [ENOTDIR]      A component of either path prefix is not a directory.

       [EINVAL]       Either pathname contains a character with the high-order bit set.

       [ENAMETOOLONG] A component of either pathname exceeded 255 characters, or entire length of either path name exceeded 1023 characters.

       [ENOENT]       A component of either path prefix does not exist.

       [EACCES]       A component of either path prefix denies search permission.

       [EACCES]       The requested link requires writing in a directory with a mode that denies write permission.

       [ELOOP]	      Too many symbolic links were encountered in translating one of the pathnames.

       [ENOENT]       The file named by name1 does not exist.

       [EEXIST]       The link named by name2 does exist.

       [EPERM]	      The file named by name1 is a directory and the effective user ID is not super-user.

       [EXDEV]	      The link named by name2 and the file named by name1 are on different file systems.

       [ENOSPC]       The directory in which the entry for the new link is being placed cannot be extended because there is no space left  on  the
		      file system containing the directory.

       [EDQUOT]       The directory in which the entry for the new link is being placed cannot be extended because the user's quota of disk blocks
		      on the file system containing the directory has been exhausted.

       [EIO]	      An I/O error occurred while reading from or writing to the file system to make the directory entry.

       [EROFS]	      The requested link requires writing in a directory on a read-only file system.

       [EFAULT]       One of the pathnames specified is outside the process's allocated address space.
