Sum Values in Multidimensional Array

I'm experimenting with arrays in PHP and I am setting up a fake environment where a "team's" record is held in arrays.

$t1 = array (
        "basicInfo" => array (
            "The Sineps",
            "December 25, 2010",
            "lemonpole"
        ),
        "overallRecord" => array (
            0,
            0,
            0,
            0
        ),
        "overallSeasons" => array (
            "season1.cs" => array (0, 0, 0),
            "season2.cs" => array (0, 0, 0)
        ),
        "matches" => array (
            "season1.cs" => array (
                "week1" => array ("12", "3", "1"),
                "week2" => array ("8", "8" ,"0"),
                "week3" => array ("8", "8" ,"0")
            ),
            "season2.cs" => array (
                "week1" => array ("9", "2", "5"),
                "week2" => array ("12", "2" ,"2")
            )
        )
);

What I am trying to 开发者_如何学JAVAachieve is to add all the wins, loss, and draws, from each season's week to their respective week. So for example, the sum of all the weeks in $t1["matches"]["season1.cs"] will be added to $t1["overallSeasons"]["season1.cs"]. The result would leave:

"overallSeasons" => array (
    "season1.cs" => array (28, 19, 1),
    "season2.cs" => array (21, 4, 7)
),

I tried to work this out on my own for the past hour and all I have gotten is a little more knowledge of for-loops and foreach-loops :o... so I think I now have the basics down such as using foreach loops and so on; however, I am still fairly new to this so bear with me! I can get the loop to point to $t1["matches"] key and go through each season but I can't seem to figure out how to add all of the wins, loss, and draw, for each individual week. For now, I'm only looking for answers concerning the overall seasons sum since I can work from there once I figure out how to achieve this. Any help will be much appreciated but please, try and keep it simple for me... or comment the code accordingly please!

Thanks!

Try this:

foreach($t1['matches'] as $season => $season_array) {
        foreach($season_array as $week => $week_array) {
                for($i=0;$i<3;$i++) {
                        $t1['overallSeasons'][$season][$i] += $week_array[$i];
                }
        }
}

This should do what you're trying to accomplish, havn't tested it though.

foreach ($t1['matches'] as $key=>$value){
   $wins = 0;
   $losses = 0;
   $draws = 0;
   foreach($value as $record){
      $wins   += $record[0];
      $losses += $record[1];
      $draws  += $record[2];
   }

   $t1['overallSeasons'][$key] = array($wins, $losses, $draws);
}
