[DarkSkull]

Try something like this:

PHP код:

new weapon[6][] = {{25},{27},{29},{30},{31},{33},{34}};
CheckWeaps(playerid) {
    for(new i = 0; i < 7, i++);  {
        if(PlayerHasWeapon(playerid, weapon[i])) return true;
    }
    return false;
}
if(CheckWeaps(playerid)) {
    // your code here
} 


This will make it easier if you wish to add more weapons along the way.
