If I understand you correctly, this is what you're looking for.

pawn Код:

new WeaponsData[MAX_PLAYERS][13],
    SavedAmmo[MAX_PLAYERS][13];

When player disconnects...

pawn Код:

for(new i; i < 13; i++)
{
    GetPlayerWeaponData(playerid, i, WeaponsData[playerid][i], SavedAmmo[playerid][i]);
}

Save WeaponsData, SavedAmmo to file...

On player connect/login, load them from the file...

pawn Код:

for(new i = 12; i > 1; i--)
{
    GivePlayerWeapon(playerid, WeaponsData[playerid][i],  SavedAmmo[playerid][i]);
}
