foreachを使用して配列内のすべての配列に値を追加する方法は？

Question

私は現在、学生のためのリビジョンタイムテーブルを作成するプログラムを設計しています。私は、2次元の配列を通過する関数を作成しようとしている、その配列のランダムな場所に対象を挿入します。すなわち、mondayのスロット12の数学が次に翌日に移動します。週は前のページの変数として設定されています。メイン配列内の各配列を選択するのに役立つだけです。ここに私の2darrayがあり、心のIVEでクマは、ユーザー場合たとえば、値を持つユーザープットを満たしたテーブルである7

$Timetable = array(
"0" => array  // 0 = Monday 6= Sunday 
        // 0 - 24 = horus 
(
    "0" => "", 
    "1" => "",

期待される結果があってもカントースペースを節約するために最初の3つの配列を含みます4時間英語の数学に6を入力し、生物学に2を入力した場合、配列はこのように見えるかもしれません。

Answer 1

あなたは、配列の各レベルに対して1つのランダムな整数でこれを行うことができます：あなたが追加したいどのように多くの「件名」に応じて、

$first = rand(0,6); 
$second = rand(0,23); 

$string = 'Random Subject'; 

$timetable[$first][$second] = $string; 

、あなたはランダムな科目の配列を作成する必要がありますし、この配列からランダムな文字列を選択することになり、別の確率変数を作成：

$subjects = ['English', 'Maths', 'Biology']; 
$subs = rand(0,count($subjects)); 

$timetable[$first][$second] = $subjects[$subs]; 

をあなたが好きな回数だけこの操作を繰り返し、または関数の内部でそれを入れて、でそれを繰り返すことができます。
