Convert HTML into textIf you want to extract the text content of a HTML document (eg - get rid of all the HTML and Javascript), try the following code:
<?php
// $document should contain an HTML document.
// This will remove HTML tags, javascript sections
// and white space. It will also convert some
// common HTML entities to their text equivalent.
$search = array ("'<script[^>]*?>.*?</script>'si", // Strip out javascript
"'<[/!]*?[^<>]*?>'si", // Strip out HTML tags
"'([rn])[s]+'", // Strip out white space
"'&(quot|#34);'i", // Replace HTML entities
"'&(amp|#38);'i",
"'&(lt|#60);'i",
"'&(gt|#62);'i",
"'&(nbsp|#160);'i",
"'&(iexcl|#161);'i",
"'&(cent|#162);'i",
"'&(pound|#163);'i",
"'&(copy|#169);'i",
"'&#(d+);'e"); // evaluate as php
$replace = array ("",
"",
"\1",
"\"",
"&",
"<",
">",
" ",
chr(161),
chr(162),
chr(163),
chr(169),
"chr(\1)");
$text = preg_replace($search, $replace, $document);
?>

Great code, but how do you use it? As a php file, but where and how do you tell it which document to parse with the script?
Thanks.
Comment by Reks on 2005-04-26
well... is there any similar ways to remove everything within the part of a document?
Comment by reks on 2005-04-26
Sorry for this second post.. My previous question was: Is there a way to remove everything within the <head> and </head>. Forgot that html tags do not work on such forms :)
Comment by rocky karhe on 2005-06-01
But its not removing html completely. Some tags like are still there.
How can i improve it to remove all
html tags.

It is very much helpful and quite handy as well

Good copy paste from the php manual
Comment by Chris Gibson on 2005-08-07
Can't you just use the functions strip_tags and htmlspecialchars?
Comment by djp on 2005-08-26
html_entity_decode converts all HTML entities to their text form
Comment by vimal on 2005-09-05
really thanks its so great and so simple to understand
Comment by Nick on 2006-01-30
The line below is incorrect.
"'([rn])[s]+'",
it should be
"'([\r\n])[\s]+'",
Also unless you want "start of heading" all over your string change.
"\1",
to
" ",
I also use...
Search.
"'&[A-Za-z]+;'si",
Replace.
" ",
That gets rid of all html chars.
Comment by Moti on 2006-10-30
to remove 'si",
Comment by Moti on 2006-10-30
to remove style tag use \\\" \\\"\\\']*?>.*?\\\'si\\\",\\\"
Comment by Moti on 2006-10-30
