The following function will remove all null values from a PHP array. This is especially useful when exploding strings with a post/prefixed delimiter.

function array_remove_null(&$array){
	$new_array = array();
	foreach($array as $k=>$v){
		if($v) $new_array[$k]=$v;
	}
	$array=$new_array;
}

To use the function simply follow the example below;

array_remove_null($your_array_object);
