PHP – 类似Gmail的电子邮件内容分离

我正在构建一个票务系统,但我不想把其中一个消息

********************************************************************************************************************************************************* **

Gmail倾向于使用“引用文字”做出相当不错的主意.有没有人知道任何预制的脚本或方法很容易做到这一点？我正在尝试将他们的回复传回我们的系统.

谢谢,

我认为你需要像我的全数组diff功能：

        About:
        I needed a function to compare a email and its response but array_diff()
        does not cover my expectations. So I reimplement a full array diff function.
        You can use it directly in your code and adopt to your needs.

function farray_diff($array1,$array2){
        $out = array();
        $max_arr = count($array1) > count($array2)? count($array1) : count($array2);

        $i = 0;
        $j = 0;

        while($i < $max_arr && $j< $max_arr){
            if($array1[$i] == $array2[$j]){
                array_push($out,$array1[$i]);
            }
            else {
                if(in_array($array1[$i],array_slice($array2,$j))){
                    for($k = $j; $k<$max_arr; $k++){
                        if($array1[$i]==$array2[$k]){
                            array_push($out,$array2[$k]);
                            $j = $k;
                            break;
                        }
                        else{
                            array_push($out,array('o' => '','n' => $array2[$k]));
                        }
                    }
                }
                elseif(in_array($array2[$j],array_slice($array1,$i))){
                    for($k = $i; $k<$max_arr; $k++){
                        if($array2[$j]==$array1[$k]){
                            array_push($out,$array1[$k]);
                            $i = $k;
                            break;
                        }
                        else {
                            array_push($out,array('o' => $array1[$k],'n' => ''));
                        }
                    }
                }
                else{
                    if(!empty($array1[$i]))
                        array_push($out,array('o' => $array1[$i],'n' => $array2[$j]));
                    else
                        array_push($out,'n' => $array2[$j]));
                }
            }
            $i++; $j++;
        }
        return $out;
    }

因此,您可以像在以下示例中一样使用它：

$str1 = "This is a simple text that can you reply,so can you do it?";
$str2 = "I response in your text: This is a simple text (no so simple) that can be replied,so can you do it? Yes,I can!";
// Printing the full array diff of single space exploded strings
print_r(farray_diff(explode(' ',$str1),explode(' ',$str2)));

返回：

它就像一个简单的差异,但是没有“”和“ – ”,在用“o”(对于旧)和“n”(对于新的)数组键进行简单解析之后,它们都已被替换.并且您可以使用以下函数来解析结果：

function format_response($diff_arr){
    $new = false;
    echo '<span class="old">';
    foreach($diff_arr as $item)
    {
        $content = '';
        if (!is_array($item)){
            $new = false;
            $content = $item;
        }
        else
            if (empty($item['o']) && !empty($item['n'])){
                $new = true;
                $content = $item['n'];
            }

        if($old_new != $new){
            if($new)
                echo '</span><span class="new">';
            else
                echo '</span><span class="old">';
        }

        echo $content . (!empty($content)?' ':'');

        $old_new = $new;
    }
    echo '</span>'; 
}

因此,您可以使用以下方法解析数组,而不是使用简单的“print_r”：

format_response(farray_diff(explode(' ',$str2)));

并且您获得(在示例后)这样的事情：

<span class="old"></span><span class="new">I response in your text: </span><span class="old">This is a simple text </span><span class="new">(no so simple) </span><span class="old">that can </span><span class="new">be replied,so can </span><span class="old">you do it? </span><span class="new">Yes,I can! </span>

显然,为了正确显示你之前需要定义css“old”和“new”类的结果,有一些不同,pex：不同的前景色：

<style>.old{color: #808080;}.new{color:#000000}</style>

对于HTML电子邮件,或者您可以修改format_response函数以显示no-html电子邮件.
