相互の正しい翻訳と思われる 2 つのコードがあります。残念ながら、それらは異なる値を返すようです。

Ruby のコード:

def separate(text,boundary = nil)
    # returns array of strings and arrays containing all of the parts of the email
    textList = []
    if !boundary #look in the email for "boundary= X"
        text.scan(/(?<=boundary=).*/) do |bound|
            textList = recursiveSplit(text,bound)
            end
    end
    if boundary 
        textList = recursiveSplit(text,boundary)
    end
    puts textList.count
    return textList
end


def recursiveSplit(chunk,boundary)
    if chunk.is_a? String
        searchString = "--" + boundary
        ar = chunk.split(searchString)
        return ar
    elsif chunk.is_a? Array
        chunk do |bit|
            recursiveSplit(bit,boundary);
        end
    end
end

PHP のコード:

function separate($text, $boundary="none"){
    #returns array of strings and arrays containing all the parts of the email
    $textBlock = [];
    if ($boundary == "none") {
        preg_match_all('/(?<=boundary=).*/', $text, $matches);
        $matches = $matches[0];
        foreach ($matches as $match) {
            $textList = recursiveSplit($text,$match);
        }
    }else {
        $textList = recursiveSplit(text,boundary);
    }
    var_dump($textList);
    return$textList;
}

function recursiveSplit($chunk,$boundary){
    if (is_string($chunk)) {
        $ar = preg_split("/--".$boundary."/", $chunk);
        //$ar = explode($searchString, $chunk);
        return $ar;
    }
    elseif (is_array($chunk)) {
        foreach ($chunk as $bit) {
            recursiveSplit($bit,$boundary);
        }
    }
}

var_dump($textList)長さ 3 の配列を示していますが、textList.count=> 4 です。何が得られますか?

BINGO ZINGO わかった！

どうやら、PHP では、その変数を含むループ内で変数を変更するには、変数の前に「&」を付ける必要があります。

「&」を追加し、いくつかの一般的な再帰エラーを修正し、スムーズに実行されました。
