Below is the exact code to get it in the array format,

<?php
        $cat = 47; //category id
        $posts=get_posts('showposts=-1&cat='. $cat);
	if ($posts) {
	 $cat_post_ids = array();
	foreach($posts as $post) {
		array_push($cat_post_ids, $post->ID);
	}
	print_r($cat_post_ids);
	}
?>

Hey MichaelH,

Better you should use this below code instead of checking the staic condition by user_id is 1.

Since you might have more than one admin also on your blog.

$isadmin = $wpdb->get_results("SELECT count(*) as count from $wpdb->usermeta WHERE user_id = $user->ID and meta_value=10");
if ($isadmin[0]->count == 0 ) {
//uncomment next line to see all values
//echo "
<pre>"; print_r($user); echo "</pre>
";
echo 'User ID ' . $user->ID . ' ' . $user->user_firstname . ' ' . $user->user_lastname ;
}
