i've made that quickly, but should work properly.

PHP Code:

stock GetLine(file[] , line = 0 , dest[] , size = sizeof dest) // in both errors, the passed string will be null;
{
    new File:f_file = fopen(file,io_read);
    if( ( !f_file || line < 0 ) && fclose(f_file) ) return 0; // When a file fails to open, it's closed.
    for(new i_lines ; fread(f_file,dest,size) ; i_lines++)
    {
        if(line == i_lines)
        {
            fclose(f_file);
            return 1;
        }
    }
    fclose(f_file);
    return -1;
}
// here it's an example of its usage.
switch(GetLine(file[],line,dest))
{
     case -1:
     {
          print("line doesn't exist");
     }
     case 0:
     {
          print("couldn't handle the file or the line is invalid");
     }
     case 1:
     {
          print(dest);
     }
} 


For solving your second issue, about the player spawn. You should save in the players files, in which city they was in their last logins.
