[PHP] Stripping carriage returns
I'm retrieving CLOB data from an Oracle database, and cleaning up the HTML
in it. I'm using the following commands:
$content =
strip_tags($description-fields['CONTENT'],'polulli');
$content = preg_replace(/p.*/,p,$content);
The second line is necessary because the p tag frequently comes with class
or style descriptions that must be eliminated.
This works on the whole except where the p tag with the style definition
is broken up over two or more lines. In other words, something like:
p class = bullettext style = line-height: normal
border: 3;
In this case, the second line of my code does not strip the class or style
definitions from the paragraph tag. I've tried:
$content = nl2br($content)
and
$content = str_replace(chr(13),$content)
and
$content = preg_replace(/[.chr(10).|.chr(13).]/,,$content)
(I've read that Oracle uses chr(10) or chr(13) to represent line breaks
internally, so I decided to give those a try as well.)
and
$content = str_replace(array('\n','\r','\r\n'),$content)
all to no avail; these all leave the line break intact, which means my
preg_replace('/p.*/','p',$content) line still breaks.
Anyone have any ideas?

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:

This should be

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
the vertical bar inside []. That's only for ().

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.

Perhaps you could use tidy to clean up the formatting (use -wrap 0) before attempting to strip out the stuff you want to get rid of.

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,
e.g.
$moditem = str_replace(array('-', '?', '!'), '_', $mystring);
you could likely do something more elegant w/ preg_replace() tho.

Re: [PHP] Stripping Characters
Hello again list.
My code for stripping characters is below. I'm hoping to get feedback
as to how rock solid it will provide the desired output under any
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`__';
$find = '/[^a-z0-9]/i';
$replace = ' ';
$new_string = preg_replace($find, $replace, $old_string);
$new_string = preg_replace(/ {2,}/, -, $new_string);
$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.

Adam (how could I not offer feedback to one with such a distinguished first

rtrim() removes the characters contained in the second argument, it doesn't
split a string using them.
I would probably use strstr() if I didn't need the other sections, or, if I
needed the other sections for later, I'd use explode:
$your_string =
'CN=NTPRTPS3-LANIER-LD335c-LH107-PPRNP9A92,OU=XXf,OU=XX,OU=X,DC=,DC=xx,DC=xxx,';
echo strstr($haystack = $your_string, $needle = ',', $before_needle =
true);

current($sections);

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);

Check out substr() with strpos().

Here's where you MIGHT get bit in the butt:

on the DATA from the DB, or any kind of PRE tags stuff you use.
Or maybe in YOUR application, neither of these matters.
Test it with JUST the output buffer and without the whitespace crunch

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.

[PHP] stripping with an OB callback
I've been coding with PHP for maybe a year. So I'm somewhat new to
it. But I've learned quickly, and created a fairly serious LAMP app
that is capable of returning large query results. During my
investigation into various means for incrementally reducing the
response sizes, I've discovered output buffering with a callback
function. So, as an experiment, I bracketed my includes of the
Fusebox files in index.php with ob_start('sweeper') and
ob_end_flush(), and placed the simple callback function at the top of
the file that performs a preg_replace on the buffer to strip all
excess space:
function sweeper($buffer) {
return preg_replace(/\s\s+/, , $buffer);
}
Results? Kinda nice! A large query result measuring over 900K of
HTML is reduced to 600K. With no change at the browser. Still valid
HTML, and the browser happily gobbles it up and displays it cleanly.
It's just 30% faster getting to me.
Now, the question. Is this going to bite me in the ass? 'Cause right
now, it looks dang good to me. Great bang for the buck, as far as I'm
concerned. I've been churning it over in my head, and I don't see a
situation (certainly not in my particular app) where doing this
whitespace reduction is going to backfire. There isn't anything in
any of this that requires the contiguous non-word characters.
I have a feeling though, that one of you more learned PHPers are going
to tell me exactly where my ass is gonna start hurtin'.

Subject: [PHP] stripping enclosed text from PHP code
Hi,
I am writing on a script that parses a PHP script and finds all function
calls
to check, if these functions exist. To do this, I needed a function that
would
strip out all text, which is enclosed in apostrophes or quotation marks.
This
is somewhat tricky, as the script needs to be aware of what really is an
enclosed text and what is PHP code. Apostrophes in quotation mark enclosed
text
should be ignored and quotation marks in apostrophe enclosed text should
be
ignored, as well. Similarly, escaped apostrophes in apostrophe enclosed
text
and escaped quotation marks in quotation mark enclosed text should be
ignored.
The following function uses preg_match to do this job.
?
function stripstrings($text) {
while (preg_match(/^(.*)(?!\\\)('|\)(.*)$/, $text, $matches)) {
$front = $matches[1];
$lim = $matches[2];
$tail = $matches[3];
while (preg_match(/^(.*)(?!\\\)('|\)(.*)$/, $front, $matches)) {
$front = $matches[1];
$tail = $matches[3] . $lim . $tail;
$lim = $matches[2];
}
if (!preg_match(/^(.*)(?!\\\)$lim(.*)$/, $tail, $matches))
break;
$string = $matches[1];
$tail = $matches[2];
while (preg_match(/^(.*)(?!\\\)$lim(.*)$/, $string, $matches)) {
$string = $matches[1];
$tail = $matches[2] . $lim . $tail;
}
$text = $front . $tail;
}
return($text);
}
?
I noticed that this function is very slow, in particular because
preg_match(/^(.*)some_string(.*)$/, $text, $matches);
always seems to find the *last* occurrence of some_string and not the
*first*
(I would need the first). There is certainly a way to write another
version
where one looks at every single character when going through $text, but
this
would make the code much more complex.
I wonder, if there is a faster *and* simple way to do the same thing.
Is there btw a script freely available, which can parse PHP code and check
for
errors ?
Any help is highly appreciated.
Winfried

Hello All,

So ^M slips right by trim and my preg_match line.
Where is the carriage return appearing in your line of output? Trim
will remove these, but only at the beginning/end of a string so if
$artist = Paul\rNowosielski that won't get cleaned up...
Maybe run them through ereg_replace() using [\n\r] as a pattern?
Or maybe use the m modifier?

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.

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);

[PHP] Stripping out all illegal characters for a folder name
Folks,
I'm taking some user input, and creating a folder on the server. I'm already
replacing with _, and stripping out a few known illegal characters (',
, /, \, etc). I need to be sure that I'm stripping out every character that
cannot be used for a folder name. What's the best way to do this? Do I have
to manually come up with a comprehensive list of illegal characters, and
then str_replace() them one by one?
There's gotta be a better way to do this...

I think you should use the reverse solution : have a list of authorized
characters and strip out all others ones.

replacing with _, and stripping out a few known illegal characters
(',
, /, \, etc). I need to be sure that I'm stripping out every character
that
cannot be used for a folder name. What's the best way to do this? Do I have
to manually come up with a comprehensive list of illegal characters, and
then str_replace() them one by one?
I think you should use the reverse solution : have a list of authorized
characters and strip out all others ones.
I'd approach it the same way.
preg_replace('/[^A-Za-z0-9_]/', '_', $dirname);

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.

[PHP] stripping comments
I'm trying to strip comments out of my code. I can get it to strip one
section of comments but the problem comes in when I have more then one
comment section to strip.
I am using this: $code = preg_replace('/\/*(.*?)*\//is', '$1', $code) and
need help fixing my regex.
example:
code 1
/* comment 1 */
code 2
/* comment 2 */
code 3
result (bad):
=
code 1
code 3
result (good):

Re: [PHP] stripping comments
You will run into more problems and there are many things you need to
consider, for example /* in a string. But token_get_all() will parse
php code for you and will make things much simpler.

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.

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;
