I guess I should have been more specific, if you store an array of integers it will truncate the rest.
PHP Code:
function onCreated(){
temp.p = findplayer("Mark Sir Link");
p.addweapon(this.name);
p.attr[17] = {1, 5, 8};
echo(p.attr[17]); //echoes 1,5,8
}
//#CLIENTSIDE
function onCreated(){
player.chat = player.attr[17]; // 1
}
