echo strip_tags($str);
?>

Example 2: Allow p and h1 html tag.

#Ruby On Rails

class User < ActiveRecord::Base
include ActionView::Helpers

def strip_comment
return true if self.comment.nil?
self.comment=sanitize(self.comment,:tags =>%w())
save
return true
end

Example 2: Allow h1 and p html tags

#model

class User < ActiveRecord::Base
include ActionView::Helpers
before_save :strip_comment
 
def strip_comment
return true if self.comment.nil?
self.comment=sanitize(self.comment,:tags =>%w(p h1))
save
return true
end

#Javascript
#Add strip_tags.js

function strip_tags (str, allowed_tags) {
 
var key = '', allowed = false;
var matches = [];
var allowed_array = [];
var allowed_tag = '';
var i = 0;
var k = '';
var html = '';</pre>
var replacer = function (search, replace, str) {
return str.split(search).join(replace);
};
 
// Build allowes tags associative array
if (allowed_tags) {
allowed_array = allowed_tags.match(/([a-zA-Z0-9]+)/gi);
}
 
str += '';
 
// Match tags
matches = str.match(/(<\/?[\S][^>]*>)/gi);
 
// Go through all HTML tags
for (key in matches) {
if (isNaN(key)) {
// IE7 Hack
continue;
}
 
// Save HTML tag
html = matches[key].toString();
 
// Is tag not in allowed list? Remove from str!
allowed = false;
 
// Go through all allowed tags
for (k in allowed_array) {
// Init
allowed_tag = allowed_array[k];
i = -1;
 
if (i != 0) { i = html.toLowerCase().indexOf('<'+allowed_tag+'>');}
if (i != 0) { i = html.toLowerCase().indexOf('<'+allowed_tag+' ');}
if (i != 0) { i = html.toLowerCase().indexOf('</'+allowed_tag)   ;}
 
// Determine
if (i == 0) {
allowed = true;
break;
}
}
 
if (!allowed) {
str = replacer(html, "", str); // Custom replace. No regexing
}
}
 
return str;
 
}
