Php 将RTF转换为纯文本
我有一个ERP系统,它以RTF格式存储文本,我试图从中提取纯文本 我在谷歌上搜索了一下,找到了一个解决方案,比如和其他一些使用REGEX替换的解决方案,但它们似乎都不起作用。我总是得到Php 将RTF转换为纯文本,php,regex,rtf,Php,Regex,Rtf,我有一个ERP系统,它以RTF格式存储文本,我试图从中提取纯文本 我在谷歌上搜索了一下,找到了一个解决方案,比如和其他一些使用REGEX替换的解决方案,但它们似乎都不起作用。我总是得到NULL或}或完全错误的东西 这是我试过的正则表达式: $matches=array('/\{\\\\(.+?)\}/','/\\\\\(.+?)\b/'); $row['text']=preg_replace($matches,,$row['text']); 但是它返回:}} 这是我的RTF数据: {\rtf1

编辑2019:对于所有发现这个问题的人,我使用这个单一类项目已经4年了,没有任何问题
经过一番脑力劳动,我为您找到了一个解决方案:
试试这个正则表达式:
"{\*?\\.+(;})|\s?\\[A-Za-z0-9]+|\s?{\s?\\[A-Za-z0-9]+\s?|\s?}\s?"
这意味着将代码替换为
$count = null;
$matches = array('"{\*?\\.+(;})|\s?\\[A-Za-z0-9]+|\s?{\s?\\[A-Za-z0-9]+\s?|\s?}\s?"');
$row['text'] = preg_replace($matches,'',$row['text'], -1, $count);
您可以在此处找到Rtf文本提取器: 下面是一个关于如何使用它的示例:
include ( 'path/to/RtfTexter.phpclass' ) ;
$doc = new RtfTexter ( 'sample.rtf' ) ;
echo $doc -> AsString ( ) ; // Echo text contents to stdout
$doc -> SaveTo ( 'sample.txt' ) ; // Save text contents to file 'sample.txt'
我在这里为其他人发布了一个解决这个问题的通用方法
public static function converToPlain($text){
$text = preg_replace('"{\*?\\\\.+(;})|\\s?\\\[A-Za-z0-9]+|\\s?{\\s?\\\[A-Za-z0-9‹]+\\s?|\\s?}\\s?"', '', $text);
return $text;
}

下面是一个似乎工作得更好的php正则表达式:
/(\{.*\}}}(\\\\(?!')\S+/m
公共静态函数convertoplan($text)
{
$text=preg\u replace(“/(\{.*\})\}{124;(\\\(?!')\S+/m)”,“”,$text);
返回$text;
}
我知道这是一个老问题,但最近我不得不做一些类似的事情,这一页上的各种答案对我帮助很大。但是没有一个答案完全满足我的需要,所以我不得不将其中的几个结合起来,然后添加一点我自己的答案
代码如下:
- 将RTF转换为TXT(非HTML)
- 处理重音或特殊字符(é、ç等)
- 还提取PNG
