Use a loop.

Код:

//~ You are inside your player data save function ~
for(new i; i<3; i++)
{
    if(pvehicle[playerid][i] != 0)
    {
         //Do things
     }
}

I recommend you to define the maximum player vehicles, e.g.:

Код:

#define MAX_PLAYER_VEHICLES 3

And change "i<3" to "i<MAX_PLAYER_VEHICLES".
