Question

我正在尝试从电子邮件中删除特殊字符和多个空行，目前我正在使用条带替换和标记的组合但是有一些问题。

PHP：

$message=strip_tags($message, "<br><p><u><span><hr><section>");
$message=preg_replace("/(<br\ ?\/?>)+/", "<br/>", $message);
$message=preg_replace( "/\s+/", " ", $message );
$message = str_replace('<p class=MsoNormal><o:p>&nbsp;</o:p></p>', '', $message);

输出是：

________________________________________
Hi,



My comp= uter and php code is acting up.
= 



This is just= a test email with whitespaces J



=   
= =

我正在发送一条带有Outlook的消息，看起来它正在用

替换每个空行

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

如何在没有任何内容的情况下替换它，删除多个空行并删除所有=字符。有什么建议？

原始类型的消息如下所示：

Hi,

My computer and php code is acting up.

This is just a test email with whitespaces :)

这就是在发送电子邮件之前Outlook代码的样子。

<p class=MsoNormal style='mso-layout-grid-align:none;text-autospace:none'><span
style='mso-ascii-font-family:Calibri;mso-hansi-font-family:Calibri;mso-bidi-font-family:
Calibri;color:black'><o:p>&nbsp;</o:p></span></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>Hi,<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>My computer and php code is acting up.<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>This is just a test email with whitespaces <span
style='font-family:Wingdings'>J</span><o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

</div>



感谢。

Answer 1

不是完美的解决方案，但似乎有效：

<?php

$s = 'Hi,



My comp= uter and php code is acting up.
= 



This is just= a test email with whitespaces J



=   
= = ';

$s = preg_replace('/=\s/', '', $s);
$s = preg_replace('/\n\n/', "", $s);
echo $s;

打印

Hi,My computer and php code is acting up.
This is justa test email with whitespaces J
