使用html2text(示例HTML到文本),根据Eclipse Public License许可.它使用PHP的DOM方法从HTML加载,然后迭代生成的DOM以提取纯文本.用法:
// when installed using the Composer package
$text = Html2Text\Html2Text::convert($html);
// usage when installed using html2text.php
require('html2text.php');
$text = convert_html_to_text($html);
虽然不完整,但它是开源的,欢迎提供.

这是另一个解决方案:
$cleaner_input = strip_tags($text);

使用DOMDocument从HTML转换为文本是一种可行的解决方案.考虑HTML2Text,它需要PHP5:
关于UTF-8,"howto"页面上的注释说明:
PHP自己对unicode的支持很差,而且它并不总能正确处理utf-8.虽然html2text脚本使用unicode-safe方法(不需要mbstring模块),但它无法始终处理PHP自己的编码处理.PHP并不真正理解像utf-8这样的unicode或编码,并使用系统的基本编码,它往往是ISO-8859系列之一.因此,在文本编辑器中看起来像utf-8或单字节的有效字符可能会被PHP误解为错误.所以,即使你认为你正在向html2text中提供一个有效的角色,你可能也不会.
作者提供了几种解决方法,并指出HTML2Text的第2版(使用DOMDocument)具有UTF-8支持.
请注意商业用途的限制.

有可靠的strip_tags函数.虽然它不漂亮.它只会消毒.您可以将它与字符串替换组合以获得您喜欢的下划线.
<?php
// to strip all tags and wrap italics with underscore
strip_tags(str_replace(array("<i>", "</i>"), array("_", "_"), $text));
// to preserve anchors...
str_replace("|a", "<a", strip_tags(str_replace("<a", "|a", $text)));
?>
你可以使用lynx和-stdin和-dump选项来实现:
<?php
$descriptorspec = array(
0 => array("pipe", "r"), // stdin is a pipe that the child will read from
1 => array("pipe", "w"), // stdout is a pipe that the child will write to
2 => array("file", "/tmp/htmp2txt.log", "a") // stderr is a file to write to
);
$process = proc_open('lynx -stdin -dump 2>&1', $descriptorspec, $pipes, '/tmp', NULL);
if (is_resource($process)) {
// $pipes now looks like this:
// 0 => writeable handle connected to child stdin
// 1 => readable handle connected to child stdout
// Any error output will be appended to htmp2txt.log
$stdin = $pipes[0];
fwrite($stdin, <<<'EOT'

你可以测试这个功能
function html2text($Document) {
$Rules = array ('@<script[^>]*?>.*?</script>@si',
'@<[\/\!]*?[^<>]*?>@si',
'@([\r\n])[\s]+@',
'@&(quot|#34);@i',
'@&(amp|#38);@i',
'@&(lt|#60);@i',
'@&(gt|#62);@i',
'@&(nbsp|#160);@i',
'@&(iexcl|#161);@i',
'@&(cent|#162);@i',
'@&(pound|#163);@i',
'@&(copy|#169);@i',
'@&(reg|#174);@i',
'@&#(d+);@e'
);
$Replace = array ('',
'',
'',
'',
'&',
'<',
'>',
' ',
chr(161),
chr(162),
chr(163),
chr(169),
chr(174),
'chr()'
);
return preg_replace($Rules, $Replace, $Document);
}
我没有找到适合的任何现有解决方案 - 简单的HTML电子邮件到简单的纯文本文件.
我打开了这个存储库,希望它可以帮助某人.麻省理工学院许可证,顺便说一下:)
https://github.com/RobQuistNL/SimpleHtmlToText
例:
$myHtml = '<b>This is HTML</b><h1>Header</h1><br/><br/>Newlines';
echo (new Parser())->parseString($myHtml);
收益:
**This is HTML**
### Header ###
Newlines
public function plainText($text)
{
$text = strip_tags($text, '<br><p><li>');
$text = preg_replace ('/<[^>]*>/', PHP_EOL, $text);
return $text;
}
$text = "string 1<br>string 2<br/><ul><li>string 3</li><li>string 4</li></ul><p>string 5</p>";
echo planText($text);
