    new File: file = fopen("phone.cfg", io_read);
    if(!fexist("phone.cfg")) { print("Couldn't find phone.cfg, created file."); fcreate("phone.cfg"); return 0; }
    while(fread(file, string))
    {
        if(strval(string) == nmbr)
        {
            fclose(file);
            return 1;
        }
    }
    fclose(file);
    return 0;
}

I would recommend using MySQL for these kinds of things.
