可能な組み合わせを提供するコードがありますが、各配列の組み合わせがありません。各配列の組み合わせを生成する方法も教えてください。述べられたコードを実行した後のように、私は可能な組み合わせを取得します....しかし、私は（ラフ、ミディアム、スモール）のような組み合わせも必要です.....
$array1 = array('rough', 'smooth', 'coarse');
$array2 = array('shiny', 'matte', 'rough');
$array3 = array('very large', 'large', 'medium', 'small');
foreach($array1 as $i)
foreach($array2 as $j)
foreach($array3 as $k)
$output[] = "$i, $j, $k";
var_dump($output);
質問はあまり明確ではありませんが、各配列を組み合わせて複数回使用したいようです。これを試して：
$array1 = array('rough', 'smooth', 'coarse');
$array2 = array('shiny', 'matte', 'rough');
$array3 = array('very large', 'large', 'medium', 'small');
$combinedArray=array_merge($array1, $array2, $array3);
foreach($combinedArray as $i)
foreach($combinedArray as $j)
foreach($combinedArray as $k)
$output[] = "$i, $j, $k";
var_dump($output);
私はこれがあなたが望むものだと思います
$array1 = array('rough', 'smooth', 'coarse');
$array2 = array('shiny', 'matte', 'rough');
$array3 = array('very large', 'large', 'medium', 'small');
generateCcombination(array($array1,$array2,$array3));
function generateCcombination($array) {
global $codes, $pos;
if(count($array)) {
for($i=0; $i<count($array[0]); $i++) {
$tmp = $array;
$codes[$pos] = $array[0][$i];
$tarr = array_shift($tmp);
$pos++;
generateCcombination($tmp);
}
} else {
echo join(", ", $codes)."<br/>";
}
$pos--;
}

これにより、すべての値のすべての可能な組み合わせが繰り返されることなく出力されます。以下に示すように：
