$latest_post_args = array( 'numberposts' => 5, 'post_type' => 'post', 'post_status' => 'publish' );
$recent_posts = wp_get_recent_posts( $latest_post_args );
$get_results = '';
foreach( $recent_posts as $recent ){
$title = $recent["post_title"];
$link = get_permalink($recent["ID"]);
if( end($recent_posts) == $recent ){
$last = null;
}else{
$last = ',';
}
$get_results .= '
{
"link":"'.$link.'",
"title":"'.$title.'"
}'.$last.'
';
}
header('Content-type:application/json');
echo '
{"recent_posts":[
'.$get_results.'
]}
';
}
