If you don't have too many problems with the HTML code (like broken
tags, etc) then maybe you could use strip_tags() which will perform
better than a regex in this instance, and should work with tags over
multiple lines as well (although I can't say I've specifically tried
that)

Neither of these have replacement values, which might just be a
typo. However, the larger issue is in the single (literal) quotes in
the second example. Change that to:
$content = str_replace(array(\n,\r,\r\n),'',$content);
If you're ambitious, you can try the FileConv PHP extension available here:

First, you can embed \r and \n directly in the regular expression as-is (not
converted to chr(10) by PHP) by using single quotes. Second, you don't want

Re: [PHP] Stripping carriage returns
Strangely, when I use \n, or nl2br(), or PHP_EOL, or anything like that, it
strips out not just line breaks, but most of the rest of the text as well. I
suspect an encoding issue at this point.
Daniel, you were right when you said that neither of my str_replace lines
had repl.acement values; that was indeed a typo when I was copying the code
over into my email.
Ashley, I've already been using strip_tags to eliminate all but p, ol,
ul, and li tags.

Richard,
Looks like you need to read up on the modifiers for preg_* functions. Start
here: http://us3.php.net/manual/en/reference.pcre.pattern.modifiers.php
I would change your second line regex to the following.
$content = preg_replace(/p.*/is, p, $content);
The modifiers after the second / are
i = case-insensitive
s = include new lines in your '.' character match.
New lines are excluded by default.
Can't remember right now, nor do I have the time to test, you might need to
invert the greediness of the match using a 'U' after the second / also.
So...
$content = preg_replace(/p.*/isU, p, $content);
YMMV
Let us know how this works out for you.
Jim Lucas
PS: you might want to swap the order of these two statements.

check the docs, the first parameter may be an array of multiple needles,

you could likely do something more elegant w/ preg_replace() tho.

circumstance:
My output must look like this (no quotes):
This-is-my-string-with-lots-of-junk-characters-in-it
The code with string looks like this:
$old_string = 'This is my $string -- with ƒ
lots˙˙˙of junk characters in it¡™£¢∞§¶•ªºœ∑´®†
¥¨ˆøπ“‘ååß∂ƒ©˙∆˚¬…æ`__';

$new_string = preg_replace(/ {1,}/, -, $new_string);
$new_string = rtrim($new_string, -);
$new_string = ltrim($new_string, -);
echo $new_string;
Will the logic above capture and remove every non alpha numeric
character and place a SINGLE hyphen between the non contiguous alpha
numeric characters?

You can remove the second line of code, as the third one is replacing
what line 2 does anyway.
Also, instead of a rtrim and ltrim, you can merge the two with a single
call to trim, which will work on both ends of the string at once.

Whoops!
I realized in the explode example I had omitted the call to count (idea
being if you didn't find any comma's, maybe you need to handle those
situations differently):
if (count($sections = explode($delimiter = ',', $string = $your_string))
1) echo $sections[0];
Although, if it doesn't matter, you could just do:
echo current(explode(',', $your_string));
And, as mentioned above, strstr() is one simple call if you won't need the
other sections:
echo strstr($your_string, ',' true);

Thanks for the follow-up Richard. I am now bracketing my Fusebox core includes with ob_start(ob_gzhandler) and ob_end_flush(). It's done wonders for those large query results.

Have you considered running php -s from the command line, which syntax
highlights your source file for you, the searching for whatever color
codes in your php.ini are used for functions?
For that matter, you could custom-code the choices for the color and
make the functions read in a separate php.ini

Re: [PHP] stripping negative number
I believe this is because taking a value and displaying it as an unsigned value isn't the same as displaying the absolute value of a number. Ever take a calculator that does hex and decimal, enter a negative number then convert it to hex? There's no negative in hex, so you end up with something odd (like zero minus one equals max value of unsigned hex.. so -40 would be 40 below the max value or something... don't know exactly how it works but I'm guessing that's what you're getting here). You might want to just use abs() to get the absolute value of the number before displaying it. -TG = = = Original message = = = I want to convert negative number to its positive equivalent. $num = -40; printf(Unsigned value is %u, $num); output is: Unsigned value is 4294967256 I have checked the manpages and %u seems the right format.

Re: [PHP] stripping text from a string
Adam,
Hi, I use a piece of proprietary software at work that uses weird session
ID strings in the URL. A sample URL looks like:
http://zed2.mdah.state.ms.us/F/CC8V7H1JF4LNBVP5KARL4KGE8AHIKP1I72JSBG6AYQSMK8YF4Y-01471?func=find-b-0
The weird session ID string changes each time you login. Anyway, how can
I strip out all of the text between the last / and the ? and insert it
into another variable? So in this case, the end result would be a
variable containing:
CC8V7H1JF4LNBVP5KARL4KGE8AHIKP1I72JSBG6AYQSMK8YF4Y-01471
You can use the parse_url() function to get just the path, and then
use strrpos() to find the last / character. Finally, use substr()
to extract the piece that you wanted.
Example:
$url_array =
parse_url('http://zed2.mdah.state.ms.us/F/CC8V7H1JF4LNBVP5KARL4KGE8AHIKP1I72JSBG6AYQSMK8YF4Y-01471?func=find-b-0');
$slash_pos = strrpos($url_array['path'],'/');
$session_ID = substr($url_array['path'],$slash_pos+1);

That's exactly it. You need to change your way of thinking. When ever you
are dealing with user input, you want to define what is GOOD and only allow
that. If you try to define what is BAD, you'll leave something out.
As for an answer:
$safe_foldername = preg_replace('/[^a-zA-Z0-9]/','',$unsafe_foldername);
That'll remove anything that's not a letter or number. Adapt to your needs.

As someone already mentioned, regexes aren't the right tool for this job.
Consider:
echo (/*); /* test */
And while that's unlikely in real code it is /possible/, and doing it the
right way is so easy due to the tokenizer functions
(http://www.php.net/manual/en/ref.tokenizer.php) that it would be foolish
not to.
The following script prints out it's own source code, sans comments (I use
something like this to replace tabs with spaces). It's adapted from a
fragment in the manual.
It removes /* comments */, !-- comments -- and // comments
?php
$incoming = file_get_contents ($PATH_TRANSLATED);
echo (strip_comments ($incoming));
function strip_comments ($in)
{
$out = '';
$tokens = token_get_all ($in);
foreach ($tokens as $token)
{
if (is_string ($token))
{
$out .= $token;
} else {
list ($id, $text) = $token;
switch ($id) {
case T_INLINE_HTML :
$out .= preg_replace ('/!--(.|\s)*?--/', '', $text);
break;
case T_COMMENT :
case T_ML_COMMENT : break;
default : $out .= $text;
break;
}
}
}
return ($out);
}
?
I'm reasonably certain I can get away with using a regex to strip HTML
comments because SGML/XML are stricter on the placing of angle brackets.
If anyone can come up with a case that breaks the regex I'll take a shot at
an XSLT-based fix.

Something like this:
?php
error_reporting(E_ALL);
$str = This string has unix\n and Windows\r\n and Mac\r line endings.;
$new_str = preg_replace('/[\n\r]+/', '', $str);
echo $str; $new_str;
?
Good luck,

RE: [PHP] stripping slashes before insert behaving badly
I am inserting data from a form into a mySQL database. I am using addslashes to escape things like ' in the data input (this is actually being done in PEAR (HTML_QuickForm). The weird thing is that the data gets written into the table like: what\'s your problem? WITH the slash. I am not sure what to modify to fix this so the literal slash is not written.

Re: [PHP] stripping %20 and other characters from query string
Sarah,
There are a couple functions that could do this for you.
Probably the fastest one for your example would be as follows.
$NewString = str_replace('%20', ' ', $value); // Removes the %20
characters
$NewString = str_replace '\', '', $NewString); // Removes \ character
echo $NewString;

on 21/11/02 2:25 AM, David Russell ([EMAIL PROTECTED]) wrote: strip_tags($_POST['Duplicate'], 'B I P A LI OL UL EM BR TT STRONG BLOCKQUOTE DIV ECODE '); OK, so this is cool. I got this list from the Slashdot allowed tags list, which I would assume is ok. Whoa there... NEVER assume because someone else does something that it's okay or safe. According to your above checks, I'm allowed to do this: B onmouseover=window.close();something evil/b Strip tags does not make a post safe at all... *safer* maybe, but no where near safe. Really, what's needed is another version of strip tags which allows you to specify allowed attributes per tag: strip_tags_attr($string, 'B P class id style A href title BR') But even that wouldn't prevent people from sneaking javascript (OR OTHER CLIENT SIDE SCRIPTING) into the href attribute. But, I haven't got enough brains to actually write the extension for PHP, so hopefully someone else will pick it up eventually. In the meantime, the only solution I can think of is to not allow btags/b... perhaps allow some other form of [i]tag[/i] tag system which doesn't allow any attributes. Then you can simply strip all tags, and then go onto replacing [b] with b, etc etc. It's a lot of work, and you will run into even more work when you choose to allow [a href=] or other attributes, but it IS safer. Or, perhaps it's cheaper for you to do some preliminary stripping of tags as per your code above, and then have a moderator physically check over the code for hidden evil.

RE: [PHP] Stripping specific tags
I was wondering is there a way to strip ONLY the tags that you specify from a page, rather than having to include all the tags you do want (using strip_tags() ) A regular expression or str_replace() would be best for this. Realize this isn't a good method, though. What if you're trying to strip images with an img tag, but a new spec comes out that allows image tags. Now you're not protected against it. That's a simple example, but it's a better policy to say X is good and allow it through, rather than to say, I know Y is bad, but I'll let everything else through and assume it's good. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Stripping specific tags
That's what I thought the answer would be. I guess I will have to see if I can create a function to add to the next release of PHP to do this, as there certainly seems to be quite a demand for it, according to the archives anyway. I hope not. That would be a worthless function to have. Did you read my post? The basic idea is validation is to allow what you _know_ is good, and kill the rest. You don't kill a couple things you know are bad, then assume the rest is good and let it in. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm with John on this one for sure... To pretend you know every possible
bad thing that can happen is plain stoopid. Develop a list of things you
accept (commonly pbibr), and turf the rest.
What I WOULD like to see in a future PHP release is a strip attributes
feature. Not sure of how to implement it, but even if you only let a few
tags through, there are still BIG problems with the tags:
B onclick=javascript: window.close() (not sure of the exact syntax) is
pretty evil.
Perhaps if strip tags could be extended so that you can list ALLOWED
attributes:
$string = striptags2('P class id styleBIBRA href target', $string)
Essentially, this would kill off any one doing an onclick/onmouseover/etc on
the allowed tags
This still leaves a few problems, the biggest of which is
href=javascript:... in a tags.
A further extension might be to list the allowed protocols of href?? There
could be an allowance for http, ftp, ext (external), rel (relative links),
javascript, and others I'm not thinking about.
striptags2('bA href[rel] target', $string)
would only allow relative links
striptags2('bA href[http|ftp|rel] target', $string)
would only allow relative, http and ftp links... NOT javascript for example
This would make striptags() a HIGHLY powerful tool for validating user input
which contains HTML. yes, it can all be done with regexp if you've got
enough time and skills, but I don't :)
Sorry for getting off topic!!

Re: [PHP] Stripping characters.....
Clarification:
So really, what you want to achieve is to ONLY have the email address?
I'm POSITIVE there's a better way with ereg_replace(), but I haven't got
time to experiment, and i'm no expert :)
So, what I figured was that you would loop through the $email, and if the
first char wasn't a , strip it out:
Chris Ditty [EMAIL PROTECTED]
Chris Ditty [EMAIL PROTECTED]
hris Ditty [EMAIL PROTECTED]
ris Ditty [EMAIL PROTECTED]
is Ditty [EMAIL PROTECTED]
...
[EMAIL PROTECTED]
You're then left with something. Assuming all your address' are wrapped
in ... , you'll now have [EMAIL PROTECTED].
Then, you want to strip out the leading and the trailing only (this
means weird email address' which have a or in them won't break.
You should now have [EMAIL PROTECTED]
UNTESTED code:
?
$email = 'Chris Ditty mail@redhotsweeps.com';
while (!eregi('^', $email))
{
$email = substr($email, 1);
//echo htmlspecialchars($email).BR;
}
$email = ereg_replace(^, , $email);
$email = ereg_replace($, , $email);
echo htmlspecialchars($email).BR;
?
Like I said, this is probably NOT the best solution, just *a* solution, but
it should work. It's independent of the 's you had in there... all it
cares about is $email ending with something, getting rid of the
preceeding it, and then getting rid of the 's that wrap it.
You might also like to get rid of anything trailing the .

Re: [PHP] stripping white space?
Hi Brian, * Persuade someone at Zend to modify PHP so that a filter function can be specified which all output text is passed through - would have the same restrictions as the header function You can already achieve this by using the built-in output buffering function. Read http://www.zend.com/manual/function.ob-start.php for more information and a simple example on this. Why not go for HTTP compression though? The gain would be much larger than just stripping out the whitespace/comments and such..

RE: [PHP] stripping white space?
I guess this is just one of those things where everyone's opinions runs in different directions, yet everyone is entitled to their own. I myself try to respect the standard because of the browser war years which made everyone uncomfortable. Now most browsers are trying to merge into a single standard (thank god). I believe the future to be XML, and I also don't think HTML will ever go away. However, I do believe that HTML will be treated more strict (hence the emergence of XHTML which is based on HTML 4.0 and XML). My suggestion to everyone is to continue using standards and try not to go astray from them, else we know the headaches us developers can face in the future.

Yeah, I know that XML requires it. And I also know that it is not a good code practice, but it perfectly works for HTML pages. Browsers compatible with the style sheets have no problems with this code (there's no connection), and if there's any XML to work on the HTML will be rewritten anyway, so there's really no reason to worry about it. Just the size gets lower and typing (escaping in PHP) is easier. I think it IS a good practice if you only practicing HTML to be outputted by PHP.

Re: [PHP] stripping white space?
Hi Maxim, 1. HTTP compression, which is not 100% compatible, but catches most of the browsers anyway. Yes. The standard PHP implementation actually inspects the HTTP headers to determine if the browser supports gzip encoding. If not, it will send the files uncompressed. Looking at our website stats, 97%+ of the people use a version 4 browser so they're fine. 2. Our own caching system: in two words: ob_*() to save the output as a text file, mod_rewrite to check for file and throw the plain .txt files if exist, PostgreSQL triggers to update (delete cached) .txt files. Hah! We think alike :) I implemented a similar system on our own website a few weeks ago. It does not cache complete pages (that's hardly possible due to the dynamic nature of our site), but instead caches HTML 'blocks'. (one page can consist of multiple blocks). Instead of serving those files directly from the filesystem I let PHP inspect them first: each file contains a timestamp that allows for expiry times. The results are wonderful: our website (http://www.blender.nl) has approximately 80.000 pageviews a day and the system load is almost never higher than 0.4. (Dual PIII/450/512MB/FreeBSD) If people are interested I'll publish the code for the caching module. 3. Browser/Platform detection: there's no need to make cross-platform heavy but compatible pages, just specific style sheets and html tags for specific browser families. Clever! That's something I will put on my to-do list as well. 4. clever HTML design, so there are less tags, tables etc, to have files smaller. And *that* also includes less comments and double quotes on integers. We do nothing with XML, so that is why I am so shocked why people here discourage me that much. In my experience once you use HTTP compression, adding a few comments or whitelines do hardly add to the filesize anymore. I don't think it's worth the trouble to write super-compact HTML. I don't know a single thing about XML, so I'll skip that discussion :) Bart -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] stripping white space?
Hi Maxim, I wrote a mini-manual about the module. You can get it with the code from: http://helium.homeip.net/stuff/cache.tar.gz I hope it helps you and I look forward to suggestions and contributions! Bart Maxim Maletsky [EMAIL PROTECTED] wrote in message news:DC017B079D81D411998C009027B7112A015ED390@EXC-TYO-01... /cache/data/articles/0-24/... /cache/data/articles/25-50/... /cache/data/searches/... this was our original idea, the difficulty is that there's the need to access this directory from several places (mod_rewrite, php and postrges). It is easy to access but might be hard to combine the URL together. But you're right, on UNIX systems, if I am not wrong, you cannot hold more then 1024 (?) files in a single directory.

Hi Maxim, I am definitely interested in seeing your caching modules - it could be a useful resource for ours. Right now our caching module is only in the planning stage, but there are few scratches I wrote myself, and it seems to be very promising. I'll do my best to write a short blurb on how to use it today and publish the code. I also have to do a zillion other things (like work on my new house), so I can't promise it'll actually be there today! There's a directory called /cached which we will store the file with the exactly same file names (with mod_rewrite there's no need to use any ?var=valetc=etc, you just get it looking like a directory) so it is extremely easy to locate a file. ie: if you go to a file articles/2000/10/26/features/doom then apache looks first into cached/articles-2000-10-26-features-doom.txt I can see one problem that you're gonna run into and that is that this directory will contain thousands of files. Not many OS's can handle that. In our case, each article has an article ID and the caching module automatically creates subdirectories that will hold a number of cached pages. Additionally, I can assign page 'types' to a page. These will generate new subdirectories as well. My caching directory looks like this: /cache/data/articles/0-24/... /cache/data/articles/25-50/... /cache/data/searches/...

Hi Remo, PS: Can anyone enlighten me concerning HTTP compression? I wish I could remember where I read this, but the PHP documentation still does not have this feature described. To enable zlib output compression, first make sure you have compiled PHP with the --with-zlib option. Next, add the following line to php.ini: zlib.output_compression = On That's all there is to it!

there is a limit of # of root entries. But the number of files per directory
is much higher. Running RH6.2 I tried this test: I have an SGI xfs
partition that does billion of entries per directory, like reiser, but for
an ext2 partition this perl script is for testing
for ($index = 1; $index = 2097153; $index++) {
open (OUT, file_$index.txt);
print OUT Test\n;
close (OUT);
}
after letting it run 4 hours :) it seems to stop at 811626 where I run out

AFAIK there's no limit (and certainly not 1024 files), but with most
filesystems accesses on large directories are painfully slow. FSs such as
ReiserFS however don't slow down noticeably on large directories...
