Tips for deleting html tags to obtain tags that can be embedded in plain text

This article mainly introduces how to delete html tags to process nested tags in plain text. For more information, see the following method: the source code in THinkphp, but I modified it.

The code is as follows:

/*
* @ Description: delete HTML tags to obtain plain text. Can process nested labels
*
*/
Class deleteHtmlTags {

Private $ filename;

Function _ construct ($ filename = 'C:/AppServ/www/text.txt '){
$ This-> filename = $ filename;
}

/**
* Delete html tags to obtain plain text. Nested tags can be processed. the restriction is that the attribute values in tags are deleted.
* @ Access public
* @ Param string $ string the html to be processed
* @ Return string
*/
Public function deletehtmltags (){
$ Content = $ this-> contentGet ();
While (strstr ($ content, '> ')){
$ CurrentBegin = strpos ($ content, '<');
$ CurrentEnd = strpos ($ content, '> ');
$ Cha = $ currentEnd-$ currentBegin-1;
$ TmpStringBegin = @ substr ($ content, 0, $ currentBegin );
// $ TmpStringMiddle = @ substr ($ content, $ currentBegin + 1, $ cha );
$ TmpStringEnd = @ substr ($ content, $ currentEnd + 1, strlen ($ content ));
// $ Content = $ tmpStringBegin. $ tmpStringMiddle. $ tmpStringEnd;
$ Content = $ tmpStringBegin. $ tmpStringEnd;
}
Return $ content;
}

Private function contentGet (){
$ Fd = fopen ($ this-> filename, 'r ');
$ Content = fread ($ fd, filesize ($ this-> filename ));
Fclose ($ fd );
Return $ content;
}
}

$ DeleteHtml = new deleteHtmlTags ();
$ Content = $ deleteHtml-> deletehtmltags ();
Echo $ content;
?>

The modified part is also above, but commented out. I personally think this method is better than regular expressions.
