As a [possibly] help tip, numerically indexed arrays always start at 0, so $i should be initialized to 0 above

The problem is each() only can return two variables; $key2 (the key) and, potentially, $value2 (an array, containing $url, $date, etc).  The nested while() loops and the for() loop above do differant things.

I would highly recommend not using the series of while loops, even if done properly; foreach() could easily do what the while() loops do, albeit still differant from what the for() loop does.

foreach( $articles as $key => $value ) {
   foreach( $value as $key2 => $value2 ) {
      echo "<br>$key2 => $value2";
   }
}
