php - Sorting Array of Categories -

i'm attempting sort following array use in foreach loop outputs latest post each of categories of goose-creek, sleepy-creek, , fobr.

i want sort array post date, i'm confused on how accomplish this. better add multiple categories wp_query args , remove foreach loop?

$feed_sources = array('goose-creek','sleepy-creek','fobr');   foreach ($feed_sources $feed) { $args = array('category_name' => $feed, 'posts_per_page' => 1); $show = new wp_query($args); $show->the_post(); 

the following code uses associative array , outputs category key , date integer value.

arsort() sorts array high low

$feed_sources = array('goose-creek','sleepy-creek','fobr'); $dates_array = array();  foreach ($feed_sources $feed) {   $args = array('category_name' => $feed, 'posts_per_page' => 1);   $show = new wp_query($args);   $show->the_post();   $dates_array[$feed] = the_date('ymdhis','','',false); }  arsort($dates_array); $ordered_sources = array_keys($dates_array);  foreach ($ordered_sources $feed) {   $args = array('category_name' => $feed, 'posts_per_page' => 1);   $show = new wp_query($args);   $show->the_post();
