You're overthinking it:

PHP код:

#include <a_samp>
enum E_PLAYER_DATA {
    
    pAdmin
};
new PlayerInfo[MAX_PLAYERS][E_PLAYER_DATA];
main() {
    new
        playerid = 10
    ;
    printf("[BEFORE] Player[%d][pAdmin] == %d", playerid, PlayerInfo[playerid][pAdmin]);
    Increase_Data(playerid, pAdmin);
    printf("[AFTER] Player[%d][pAdmin] == %d", playerid, PlayerInfo[playerid][pAdmin]);
}
Increase_Data(playerid, E_PLAYER_DATA:enumerator) {
    PlayerInfo[playerid][enumerator] ++;
    return true;
}
