Limiting the number of blogs displayed with get_last_updated

Hello,

I’m using this function on my site :

<?php
$blogs = get_last_updated();
if( is_array( $blogs ) ) {
?>

<h3>Updated Blogs</h3>
<?php foreach( $blogs as $details ) {
?>” target=”_blank”><?php echo get_blog_option( $details[ ‘blog_id’ ], ‘blogname’ ) ?>
<?php
}
?>

<?php
}
?>

I would like to know, how to modify it by displaying only the five latest blogs ?

Thanks you for your help.

Best regards,
