jsonencode add an empty row, why? - php

Question

I've done a long search before posting, none of solutions work for me.
I'm creating an Android application, using JSON and PHP;
PHP
/**
*
LOT OF USELESS THING
*
*/
//Attributing values of $OUTPUT
$q=mysql_query($query);
if (!$q)
die(mysql_error()); // You'll be notified if there's any syntax error in your query.
$OUTPUT = array(array());
if ($q && #mysql_num_rows($q) > 0) {
// looping through all results
// products node
while($e=#mysql_fetch_assoc($q)){
if (!empty($e['title'])){
$u = Array();
$u['id'] = mb_convert_encoding($e['id'], 'UTF-8');
$u['title'] = mb_convert_encoding($e['title'], 'UTF-8');
$u['location_search_text'] = mb_convert_encoding($e['location_search_text'], 'UTF-8');
$OUTPUT[] = $u;}
//echo "<br>************<br>";*/
//$OUTPUT[] = $e;
}
}
print(json_encode($OUTPUT));
Now, this is the output of json:
[[],{"id":"796","title":"ANSEJ ORAN \/Agence de Soutien \u00e0 l'Emploi des Jeunes d'Oran","locat ...etc
If you see, there's a []; an empty array, which of course causes me problem in Java, when parsing data with
JSONArray jArray = new JSONArray(result);
Occuring me a JSONExcpetion:
Error parsing data org.json.JSONException: Value [] at 0 of type org.json.JSONArray cannot be converted to JSONObject

Answer 1

Not $OUTPUT = array(array()); - this create empty array inside
But $OUTPUT = array();
