Question

我正在尝试编写一个PHP脚本，将图像通过电子邮件发送给自己。我有更多的功能，如发送json文件等，但这些工作。

当我使用XAMPP运行脚本时，我使用哈希来比较发送前的图像和发送的图像。哈希不匹配。我在十六进制编辑器中打开了这两个图像（注意我为我正在测试和代码更改的许多图像做了这个）并且我注意到，对于每个0x00，它被替换为0x20。现在我希望这是解决这个问题的唯一问题。

提前致谢！

function generateBoundary()
    {
        $boundary = md5(time());
        return "=============\" . $boundary \"=============";
    }

    function attachImageFile($path, $boundary, $content_type, $encoding_type)
    {
        $start = strrpos($path, '/') == -1 ? strrpos($path, '//') : strrpos($path, '/')+1;
        $file_name = substr($path, $start, strlen($path));
        $file = fopen($path,'r');
        $data = fread($file, filesize($path));
        fclose($file);

        $finfo = finfo_open(FILEINFO_MIME_TYPE);
        $ftype = finfo_file($finfo, $path);

        $message =
            "--{$boundary}\r\n" .
            "Content-Type: {$ftype}; " .
            "name=\"{$file_name}\"\r\n" .
            "Content-Transfer-Encoding: {$encoding_type}\r\n" .
            "Content-Disposition: attachment;" . " filename=\"{$file_name}\"\r\n" .
            $data . "\r\n";

        return $message;
    }

    function generateMessage($body, $boundary)
    {
        // at this point all data will be seperated by boundary, text, files, etc, so ow we will use it to seperate the email body
        //$message = "TEST!!!!!!!!!!!!!!!!: \r\n" .
        $message =
            // the -- is needed before the boundary
            "--{$boundary}\r\n" .
            // charset=ISO-8859-1 is choosen since it covers a good amount of chars: https://www.w3schools.com/html/html_charset.asp
            "Content-Type:text/html; charset = \"iso-8859-1\"\r\n" .
            // https://stackoverflow.com/questions/25710599/content-transfer-encoding-7bit-or-8-bit
            "Content-Transfer-Encoding: 7bit\r\n" .
            // body text
            $body . "\r\n";
        return $message;
    }

    $to = "myemail@gmail.com";
    // email
    $subject = "subject";
    $header = "From:donotreply@fake.com \r\n";
    $header .= "MIME-Version: 1.0\r\n";
    $boundary = generateBoundary();
    $header .=
        "Content-Type: multipart/mixed; " .
        "boundary=\"{$boundary}\"\r\n";

    $message = "";
    $message .= generateMessage("THIS IS THE BODY", $boundary);

    $message .= attachImageFile("./test2/wallpaper.jpeg", $boundary, "image/jpeg", "binary");

    // last message needs to end the body
    $message .= "--{$boundary}\r\n";

    $result= mail ($to, $subject, $message, $header);

    if( $result == true ) {
        echo "Message sent";
    }else {
        echo "Message not sent";
    }

编辑0：我试过7bit，8bit，base64

编辑1：当我点击我的Gmail帐户上的show original时，我也想添加

To: fake@gmail.com
Subject: Report Number
X-PHP-Originating-Script: 505:index.php
From: donotreply@fake.com
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="=============" . f14134bdf626542e17344e7377f1f281 "============="
Message-Id: <20170321015658.8DC30D3471A@MacBook.localdomain>
Date: Mon, 20 Mar 2017 18:56:58 -0700 (PDT)

Content-Type: text/html; charset = "iso-8859-1"
Content-Transfer-Encoding: 7bit

THIS IS THE BODY
Content-Type: image/jpeg; name="wallpaper.jpeg"
Content-Transfer-Encoding: binary
Content-Disposition: attachment; filename="wallpaper.jpeg"

该文件包含数据，除了0x20问题，以及相同的大小（以MB为单位），但它没有像我在添加代码发送文本文件时那样显示在这里。不确定这是否有用

Lamp / Cakephp: Streaming an image : Binary 0x00 replaced by 0x20

编辑2：在0x22问题之后，文件实际上开始有错误的数据（二进制和十六进制）。这是一个样本

已发送文件（粗体显示它开始用0x20替换0x00，但不久之后数据只是坏数据不再是0x200问题）
