Re: [PHP] strip_tags
If you are sanitizing _POST input for a database by escaping (via mysql_*), is there a reason to use strip_tags()? If so, why and could you provide an example? Not really, as long as you're using something like mysql_real_escape_string(). Though if you're redisplaying it to your users (ie something like a forum) then you might want to use strip_tags() to get rid of any HTML. -- Richard Heyes http://www.phpguru.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For one, often the contents are rendered in a web browser and you may not want the full array of HTML tags to appear in the generated source code either for security reasons or for aesthetics. Another is that a lot of times HTML code can have tag bloat. Unnecessary tags reduce the amount of actual content you can store in a limited character column even though they may contribute little useful formatting. I think it's a good idea to decide exactly what HTML tags you want to allow. Then you have a few options with what you do with tags you don't want, such as stripping them out using strip_tags() with the optional parameter to allow those tags, or escaping the rest of the text with htmlspecialchars(). If you strip the tags out, it makes sense to do this before you save the value so they only need to be stripped out once.

However, when shoving the data to the browser, I use htmlentities(). Is it recommended to use strip_tags() before sending to htmlentities()? Not unless you need to strip HTML tags. Usually htmlspecialchars() is enough. -- Richard Heyes http://www.phpguru.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Incrementing variables based on database data

the database, many of each of these possible values for $i[4], however

incremented and it is getting incremented for every row in the table. Can
anyone see anything I'm doing incorrectly? The data in this column in the
table is formatted as TEXT. Thanks in advance for any help you can provide.

Re: [PHP] Re: Incrementing variables based on database data
Well, what I need to be able to do is then take the numbers of each count
and figure out which is used the most. We use this database to log actions
taken on servers in our network. What my boss wants me to come up with is a
list of which commands are issued the most, which servers get the most
attention, and for each server, which command is issued the most, and so I
was going to kind of do it messy-like as I'm not really 100% sure of the
best way to do it, but my goal was to create the count variables and then
compare them using if statements to see which one is used the most. If you
have a way of doing this more efficiently, I'd love to hear it. I'm not the
best programmer in the world and I'm kind of just getting back into this
stuff, so I'm all ears for any suggestions you may have =)

Re: [PHP] Re: Incrementing variables based on database data
Well, MySQL can aggregate the data for you so you don't have to pass it
to PHP. It can just give you the results. I suggest reading up on the
SELECT COUNT syntax and the GROUP BY syntax in MySQL.

The database won't care whether the content includes HTML tags.
So, in
that sense, there isn't a reason.
However, there are other reasons. For one, often the contents are
rendered in a web browser and you may not want the full array of
HTML
tags to appear in the generated source code either for security
reasons or for aesthetics. Another is that a lot of times HTML code
can have tag bloat. Unnecessary tags reduce the amount of actual
content you can store in a limited character column even though they
may contribute little useful formatting.
I think it's a good idea to decide exactly what HTML tags you want
to
allow. Then you have a few options with what you do with tags you
don't want, such as stripping them out using strip_tags() with the
optional parameter to allow those tags, or escaping the rest of the

sense to do this before you save the value so they only need to be

Try it and see, but it looks like the answer is it depends. I ran
your message text through strip_tags and it seems to remove the
greater-than signs when followed by non-whitespace characters, but
left them when they were surrounded by whitespace. Compare below to
your original message:

Thanks Andrew and Richard. I have another question which I can't seem
to find in the manual.
Will strip_tags() only strip known HTML tags or will it just strip
anything within and ? I have some encrypted data that may contain
and , and I don't want strip_tags() to remove the characters in this
encrypted string.

I did a similar test:
?php
$strs = array(
DÃý€û¥63 ôà ×¼7,
DÃý€û¥63 ôà ×¼7,
DÃý€ û¥63 ôà ×¼7,
pHow are you doing?/p,
);
echo pre\nstr:\n;
foreach ($strs as $i = $str) {
echo $i = . htmlentities ($str) . \n;
}
echo \nstripped:\n;
foreach ($strs as $i = $str) {
echo $i = . htmlentities (strip_tags($str)) . \n;
}
echo /pre\n;
?
The output from this was:
str:
0 = DÃý€û¥63 ôà ×¼7
1 = DÃý€û¥63 ôà ×¼7
2 = DÃý€ û¥63 ôà ×¼7
3 = pHow are you doing?/p
stripped:
0 = û¥63 ôà ×¼7
1 =
2 = DÃý€ û¥63 ôà ×¼7
3 = How are you doing?
Notice how stripped[1] is empty. This occurred when I removed the
closing . I find this to be a bit odd. Oh well. Maybe a bug or feature?
Nonetheless, I test if it is an encrypted string, then don't call
strip_tags() on it. Otherwise, do. This seems like it will work well.
Thanks for the input!

[PHP] A dumb question regarding sending email
Hi gang: I wish I had another identify for asking dumb questions, but it's late and I'm tried -- so here goes. I have a herdoc that I send out as an email -- no problems there. However, how do I include a link within it? If I use http://example.com, it's just a string but not an actual link. So, how do you format a link in a heredoc?

If I use http://example.com, it's just a string but not an actual link. So, how do you format a link in a heredoc? a) most email programs will detect that plain-text URL and turn it into a link when displaying the email, so... maybe you don't want to bother! b) send the email with an HTML body (either instead of or in addition to the plain-text body), and use the standard a href='http://example.com/'http://example.com//a in the HTML body. You'll need to catch the heredoc as a string, and replace any URLs with the anchored URL as above. -- Ross McKay, Toronto, NSW Australia Before enlightenment: chop wood, carry water; After enlightenment: chop wood, carry water - Wu Li -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You sent that email as text-only and thunderbird turned it into a link for me. If you're trying to send an a href.. link, you need to send it as a full html email (which means setting proper email headers etc).. for that I'd suggest using one of the libraries to do it all for you (phpmailer, swiftmail or whatever it is, zend_mailer)... -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] More math fun
Robert, when you do yours, it's performing the same function on two different variable types and has to do a conversion before the function works. He was doing a numeric function on a string which might be giving the funky results.
