PHP: Delete entry in array of arrays - php

Question

I need to display "Featured posts" randomly for each day of the week on a single page. Posts need to be current.
What I want to do:
I load 7 posts in a variable using WP_Query, test each post to see if it's current, and display only the remaining ones.
Problem: I can't find how to delete an entry in a while loop.
Init of the page:
$args = array(
'post_type' => 'listing',
'post_status' => 'publish',
'post__not_in' => array($post->ID),
'orderby' => 'date',
'order' => 'DESC',
'meta_key' => 'featured_calendar',
'meta_value' => 'on',
'posts_per_page' => 7
);
$featured = new WP_Query($args);
if ($featured->have_posts()) : while ($featured->have_posts()) : $featured->the_post();
$theending = get_post_meta($post->ID, 'theend', true);
if ($theending > time()){
echo "All Good";
} else{
//Delete the entry
}
endwhile;
endif;
Inside the days of the week loop:
if ($featured->have_posts()) : while ($featured->have_posts()) : $featured->the_post();
//Display of remaining posts
endwhile;
endif;

Answer 1

It sounds like you should just modify the query to exclude those posts in the first place:
$args = array(
'post_type' => 'listing',
'post_status' => 'publish',
'post__not_in' => array($post->ID),
'orderby' => 'date',
'order' => 'DESC',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'featured_calendar',
'value' => 'on',
'compare' => '='
),
array(
'key' => 'theend',
'value' => time(),
'compare' => '>',
'type' => 'NUMERIC' // Not sure if you want a TIME here
),
),
'posts_per_page' => 7
);
$featured = new WP_Query($args);

Answer 2

If you're looking to remove a row from an array, you can do that like this:
unset ($array[$key]);

Answer 3

$recent_featured = array();
$featured = new WP_Query($args);
if ($featured->have_posts()) : while ($featured->have_posts()) : $featured->the_post();
$theending = get_post_meta($post->ID, 'theend', true);
if ($theending > time()){
$recent_featured[] = $post;
} else{
}
endwhile;
now you can use $recent_featured, pass it, loop over it, display them...
