Mysql Data Only Pulling Last Result Into Json Array - php

Question

I'm pulling multiple rows from a table and formatting them to this standard: 3 Swords, 5 Daggers, etc.
Well When I try to put that data into a json Array, It's only pulling the last result as this [{"weapons":"You Used: 3 Rusty Dagger's, "}] Which it should say: [{"weapons":"You Used: 3 Rusty Dagger's, 2 Swords"}]
Here's The Query I'm currently using, Which will show perfectly inside of the while loop:
$get_weapons = mysql_query("SELECT
O.player_id,
O.item_id,
O.name,
O.attack,
O.defense,
O.type,
O.owned,
(SELECT
sum(owned) FROM items_owned
WHERE owned <= O.owned AND player_id=$id) 'RunningTotal'
FROM items_owned O
HAVING RunningTotal <= $mob_avail
ORDER BY attack DESC");
// Get Weapon Info
while($weapon = mysql_fetch_array($get_weapons)){
$weapon_id = $weapon['item_id'];
$weapon_name = $weapon['name'];
$weapon_attack = $weapon['attack'];
$weapon_defense = $weapon['defense'];
$weapon_owned = $weapon['owned'];
// Formatting Weapons Message
$weapon_message = 'You Used: '.$weapon_owned.' '.$weapon_name.'\'s, ';
}
$data[] = array('weapons'=>$weapon_message);
echo json_encode($data);
I understand that the $data array is outside of the while loop, But I'm only needing a total of one arrays, so I'm kind of stuck on what to do to fix this issue. Any help would be awesome

Answer 1

You should add one static variable before append the results into the message.
Here is the reference answer:
$get_weapons = mysql_query("SELECT O.player_id, O.item_id, O.name, O.attack, O.defense, O.type, O.owned, (
SELECT sum(owned) FROM items_owned WHERE owned <= O.owned AND player_id=$id) 'RunningTotal' FROM items_owned O HAVING RunningTotal <= $mob_avail ORDER BY attack DESC");
// Initialize the message
$weapon_message = 'You Used: ';
// Get Weapon Info
while($weapon = mysql_fetch_array($get_weapons)){
$weapon_id = $weapon['item_id'];
$weapon_name = $weapon['name'];
$weapon_attack = $weapon['attack'];
$weapon_defense = $weapon['defense'];
$weapon_owned = $weapon['owned'];
// Formatting Weapons Message
$weapon_message = $weapon_message.$weapon_owned.' '.$weapon_name.'\'s, ';
}
$data[] = array('weapons'=>$weapon_message);
echo json_encode($data);
