Export Arrays to .csv

Hi,

I use the WP Export Users Plus plugin to export users to an .csv file. I’m modifying this to my needs.
However I now come to a part where I need to export arrays.
My arrays are build in the following way.
Array
(
[key(numeral)] => value(string)
)

In the pluginscript the export is done with an foreach loop to get all the values out of the array.

I want every value in the array on a separate line with an separate header.
The plugin tells the array to output the header as the key in the database.
The plugin also uses a sertain script to export a single value of an array but I can’t seem to get this to work on my custom array’s

This is what I now have.

if ($get_appartment) {
		$user = get_userdata( $user->ID );
		$unit= $user->{'appartment'};
		$handle = fopen('php://temp', 'r+');

		foreach ($unit as $appartment) {
			   $appartment = fputcsv($handle, $unit);
		}
		print($appartment);
		fclose($handle);
}

if ($get_appartment == '') { $gapp = ''; } else { $gapp = $appartment . ", "; }

This outputs all kinds of values that I can’t find in my database.

The original script uses this to output array values:

if ($get_user_role) { 

	$user = get_userdata( $user->ID );
	$capabilities = $user->{$wpdb->prefix . 'capabilities'};

	if ( !isset( $wp_roles ) )
		$wp_roles = new WP_Roles();

	foreach ( $wp_roles->role_names as $role => $name ) {

		if ( array_key_exists( $role, $capabilities ) )
			$roleM = $role;
	}

}

if ($get_user_role == '') { $gur = ''; } else { $gur = $roleM . ", "; }

I hope somebody can help me with this.
