From ruby to PHP

[mr_murph]

Hello everyone,

I´m new at this forum and I don´t know if this is the right place to post this message, so please don´t be angry if I´m in the wrong place

 

I´ve got a Ruby script to distribute a group of teams into a calendar, but it´s written in ruby. I understand what it does but I need some help to translate it to PHP.

 

Please, can anybody help me?? I´d be so thankful.

 

This is the ruby script:

def make_rounds(clubs)
  
  #If odd insert dummy club
  if clubs.length % 2 == 1
    clubs << "X"
  end
  
  rounds_home = []
  rounds_away = []
  num_rounds = clubs.length - 2
  num_matches = clubs.length / 2 - 1

  for i in (0..num_rounds)
    matches_home = []
    matches_away = []
    for j in (0..num_matches)
      matches_home << [clubs[j], clubs[num_rounds - j + 1]] #Home match
      matches_away << [clubs[num_rounds - j + 1], clubs[j]] #Away match 
    end
    rounds_home << matches_home
    rounds_away << matches_away
    #rotating the teams
    last = clubs.pop 
    clubs.insert(1, last)
  end
  
  
  rounds_away.each { |x| rounds_home << x}
  return rounds_home
end

def print_rounds(rounds)
  i = 1
  rounds.each do |round|
    puts "Round: #{i}"
    round.each do |match|
      puts "Match: #{match[0]} - #{match[1]}"
    end
    i += 1
  end
end


clubs = ("A".."T").collect {|x| x}
rounds = make_rounds(clubs)
print_rounds(rounds)

 

Thanks in advance

I´ve finally solved this problem.

 

Let me know if you want to know the answer.

Please tell me if I´m doing something wrong or just if it could be done better as I´m also new whit PHP.

 

The main function, make_rounds():

 

function make_rounds($clubs){	

	#If odd insert dummy club	
	if (count($clubs) %2 == 1) $clubs[]="X";

	$rounds_home = array();
	$rounds_away = array();
	$num_rounds = count($clubs)-2;
	$num_matches = count($clubs)/2-1;

	for ($i=0; $i < $num_rounds+1; $i++) { 
		$matches_home=array();
		$matches_away=array();
		for ($j=0; $j < $num_matches+1; $j++) { 
			$matches_home[]=array(
				"home_team" => $clubs[$j], 
				"away_team" => $clubs[$num_rounds - $j + 1]
			);
			$matches_away[]=array(
				"home_team" => $clubs[$num_rounds - $j + 1], 
				"away_team" => $clubs[$j]
			);
		}
		$rounds_home[]=$matches_home;
		$rounds_away[]=$matches_away;


		# rotating the teams
		$first = $clubs[1];
		foreach ($clubs as $k => $club) {
			if ($k != 0 && $k != count($clubs)-1) {
				$next = $k+1;
				$clubs[$k] = $clubs[$next];
			}

			if ($k == count($clubs)-1) $clubs[$k] = $first; 
		}


	}

	# Adding away rounds to the final calendar
	foreach ($rounds_away as $i => $round) $rounds_home[]=$round;

	return $rounds_home;

}

 

When calling this function, it needs an array with the teams as an argument.

 

I´m not sure if I´m doing the same thing when rotating the teams (line 28). It seems to work, but I need to test it harder.

 

The function print_rounds is just a foreach to display the round values.

 

Thanks.
