[PHP] Re: When to use htmlentities()
If you store your text htmlentitied in the database, you will need to apply htmlentities to the search string, but not when you bring the data back from the database tables (to either display in the text editing screen, or the normal viewing screen. Example: ?php $text = This is a test /textarea; ? textarea name=text cols=50 rows=10 wrap=virtual?php echo $textarea; ?/textarea That will not bring a desirable result, without applying htmlentities(): textarea name=text cols=50 rows=10 wrap=virtual?php echo htmlentities($textarea); ?/textarea I prefer to store text as-is in the database, then perform htmlentities when retrieving from the database. I tend to keep other text manipulation to basic one-time tasks, like word breaking (for big chunks of words), multi-space removal, etc. James Rotsky [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Okay, I'm starting to tie myself in knots with this: Part of my site carries feature articles held in a MySQL database. I've written an admin page that allows me to edit the articles in an HTML form before saving them to the database (using INSERT or UPDATE as appropriate). On the site, I want users to be able to search using keywords in the articles. Now, all of this is basically working, but I'm not sure quite what to do about special characters. If I use htmlentities on the data when writing it to the database, then an ampersand will be stored as amp; and this will display fine. But then I guess I need to similarly treat search strings if users' queries are to match properly. Also, if I pull the article into the editing form, I guess I need to reverse the process with html_entity_decode() before displaying and editing it, which is getting a bit convoluted. Is there any reason why I shouldn't store characters in their natural form in the database - (eg, store '' as '' rather than 'amp;') and then just use htmlentities to display the text?

[PHP] Re: File manipulation tutorials / helpful resources
Tony, try searching the archives - the regular expression that's required to

before.
Here's a quick bit of code that might get you started:
?php
$temp_file = /tmp/ . uniqid(yahoo);
$myfile = /path/to/myfile.html;
$file = http://www.yahoo.com/;;
$their_text = implode(, file($file));
# now let's get our match between the body tags.
if(!preg_match(!body[^]+(.*)/body!is, $their_text, $matches))
{
# No matches?
} else
{
$my_text = $matches[1];
# Copy to temp file first
$fp = fopen($temp_file, w);
fwrite($fp, $my_text);
fclose($fp);
if(filesize($temp_file) 0)
{
# We probably got some good text.
copy($temp_file, $myfile);
} else
{
echo Something flakey's happened.\n;
}
unlink($temp_file);
}

Re: [PHP] Months of the year

[PHP] Re: Code contents of a function
Output buffering functions sound like something you could use:
?php
function OtherStuff()
{
echo MONKEY!!!br\n;
}
function DoStuff()
{
echo Somethingbr\n;
echo Something elsebr\n;
OtherStuff();
}
// Start output buffering.
ob_start();
// Grab the content.
DoStuff();
$content = ob_get_contents();
// Finish up.
ob_end_clean();
// What to do with $content?
echo Content is: b . $content . /b\n;
?
However, this could get messy and might not be what you're really after. If
you're just wanting to return values from your functions, use return:
function OtherStuff()
{
return Monkey!br\n;
}
function DoStuff()
{
$output = Somethingbr\n;
$output .= Something elsebr\n;
$output .= OtherStuff();
return $output;
}
$content = DoStuff();
echo Content = . $content;
would have a similar effect to the output method above.
Anyway, further reference for you on output buffering can be found here:

Re: [PHP] Re: mysql_num_rows
I would also tend to do a count(*) as well as the main query if I intend to
use pagination (with the help of LIMIT in the main query).
Suppose, for example, you're limiting to 30 news posts per page, and from
calculations there are only 2 pages that fall into the criteria, then trying
to bring the result set back on page 3 when it doesn't exist will result
in a warning. Also, you'll want to know how many pages of the news post
there are...
Brief Example (assuming $page has already been validated as an integer):
$num = 30; // per page
$total = 49; // result from count(*)
$total_pages = ceil($total/$num);
if($page $total_pages)
{
$page = $total_pages;
}
// Main query.
// select [whatever] from [table(s)] where [criteria] [whateverelse] limit
. (($page*$num)-$num) . ,$num;

First, there is no reason to do mycounter like this
when mysql_num_rows() will work perfectly. It's not
based on any certain column numbers or primary keys.
Although if you're suggesting this method to simply
print 0-n in the loop (as users may want to know the
row number of output not any id number) then that's
good altough it's not really a counter in this case.
Second, we assume this person wants a count for
informational purposes, to go along with the
data in which case mysql_num_rows() is your best
bet. It means having a count before the data is
printed/used. And checking the number or rows
returned before fetching is a form of error handling
as well as if it equals 0 than there is no data to
fetch. But if one ONLY wants a number of rows count,
doing SELECT count(*)... works great as suggested
below.

Re: [PHP] Struggling with code
Ben, consider re-working this slightly: $result = mysql_query($sql,$connection) or mysql_error(Couldn't execute query.); mysql_error() doesn't take any arguments (other than maybe a resource identifier ($connection, in this case)): it simply outputs problems, which allows you to diagnose what's wrong with your script. Try throwing a bum query in there and see what you get (I'm guessing it would be not a valid mysql resource on line 21/22, which you've already reported in another e-mail).

I think it is also good to fetch $mem as:
$fp = fopen('index.htm', 'r');
$mem = fread($fp, filesize('index.htm'));
fclose($fp);
that will keep index.htm formatted as is.

included. I have one other page so far, datetime.php. I wanted to
let datatime run itself by including the headers and footers on its own

this code works when datetime.php is included by index.php, but on its

the xhtml code outside the php code in the file. its like the entire

}
return $var;
}
and now all of the table tags are lowercase. Much nicer.

[PHP] Re: RegEx and ?
Hi Berber,
you generally need to do some string replacements on the text you're using
to put through the match before you actually do the match (and same for
replacements). Just have a look at the pattern syntax in the manual for the
characters you need to do the replacement on... e.g
$string = Will this work?;
$criteria = work?;
$criteria = str_replace(?, \?, $criteria);
if (preg_match(/ . $criteria . /is, $string))
{
echo Bingo.;
}
I usually make a function that will replace all the special characters. The
only one that stands out against the rest is the $, because escaped once in
a pcre function means that it is a variable - you need to escape it twice.
Here's some of what I tend to use (cut out a function - the rest of the
function won't mean much to you ;)):
// Clear up the special characters in the $criteria.
$criteria = str_replace(^, \^, $criteria);
$criteria = str_replace([, \[, $criteria);
$criteria = str_replace(], \], $criteria);
$criteria = str_replace(*, \*, $criteria);
$criteria = str_replace(+, \+, $criteria);
$criteria = str_replace({, \}, $criteria);
$criteria = str_replace(}, \}, $criteria);
$criteria = str_replace(?, \?, $criteria);
$criteria = str_replace(|, \|, $criteria);
// The $ is a little tricky, since it is used for end of string / line,
// and for use with variables when escaped. It therefore needs two
// backslashes.
$criteria = str_replace($, \\$, $criteria);
// We're using ! as a delimiter, so that must be replaced, too.
$criteria = str_replace(!, \!, $criteria);
There's probably bits missing from that, since that's from a script in
development, but you get the idea.
Hope it's of some help,
James

First off, you're using eregi (case insensitive), but defining a-zA-Z (a
through z, case insensitive) in your characters class. You could just use
ereg and leave the character class as it is, or drop the A-Z from the eregi
version.
Secondly, I'd amend your code to:
^[a-z]+$
And thirdly, I'd just use a combination of ereg / preg_* functions and
strlen.
if(preg_match(/^[a-z]+$/i, $string) strlen($string) 255)

echo Whatever.;

I'm not sure why you're getting that error, but then again, I haven't

} else {
$result = $a . $operator . $b;
echo $a $operator $b= . CalculateValues($a, $operator, $b);
}

?
If the values are known, just hard code them. If not, you'll want to pay
closer attention to the user input.
It's not fully what you're after, but it's enough to get you started anyway.

Hi all, Further to a discussion we had yesterday about the danger of onLoad, onMouseOver, etc etc of allowed tags when using strip_tags(), I've decided to look at the issue from another angle. For the limited set of tags I usually allow on user input, BIU, I'm going take the approach of deleting anything I don't specifically TRUST, rather than deleting things I don't trust. For such simple tags, It seems to me to be a smarter move to delete anything in the tag apart from the actual tag. Banything else becomes B This eliminates the danger of people putting anything evil like onmouseover=javascript:self.close(); into my small set of allowed tags. So, I'd like a regexp which looks for multiple occurences of a tag (let's take B for an example), and throw out anything not needed. In English, I guess it looks like: look for a followed by a b (case insensitive), then throw away anything up to the first we find. Better still would be a regexp or function that checks for b|i|u, or a passed set of tags. I'm aware that this type of hard-line approach will prevent B id=foo, and I will also have problems on things like FONT face=something and A HREF=foo.php, but I plan to devise some psuedo tags for links, and don't require font tags, image tags, etc etc. Many thanks in advance, Justin French -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hello James,

I have a site where users can type whatever they want in and it posts it

down enter for a couple of seconds and scroll everything off the page. I'm
trying to figure out a regex pattern that searches for say, more than 5
br

how to possibly do this?
First of all, store all of your information in your database as it's
entered, and perform the regex and other string manipulation on the code
when you bring it out of the database. That way, if you decide you could do
something better than you're currently doing later on, you have the raw
data to deal with.
Anyway, now to your problem:
?
$string = lots of
new
lines
grr!;
// Change the 2 to whatever you want: if you want
// to limit to three new lines, change to 3 and add another
// \n (new line)
$string = preg_replace(/(\r?\n){2,}/, \n\n, $string);
echo nl2br($string);
?
Hope it helps.

The function takes three arguments; type, url, and link text / image.

// Function to auto append the session id to a link: takes the link and name
of link and
// the type of link (a=, b=?) as arguments.
function AppendSessionId($link, $label, $type) {
$display = a href=\ . $link;
if (SID) {
if ($type == a) {
$display .= ;
} else
if ($type == b) {
$display .= ?;
}
$display .= SID;
}
$display .= \ . $label . /a;
return $display;
}
The type is for appending the SID onto links that already have a query
string. So if you did:
echo AppendSessionId(page.php?id=1, Page 1, a);
URL output would be:
page.php?id=1session_id_variable_name=34567890
If the user has cookies enabled, ouput would simply be:
page.php?id=1
If you use type b, then the sid is appended with a question mark (new
query string is started) for those users without cookies enabled:
echo AppendSessionId(page.php, My page, b);
output would be:
page.php for cookies enabled users and
page.php?session_id_variable_name=23456789 for those who cause us problems.
Hope that helps. If anyone's got a better solution, I'm all ears! :)

Is there any other way of enabling trans_sid besides when compiling php?
Can I enable it in the php.ini file or .htaccess? And if so what would the
syntax be? I've tried multiple things, but nothing seems to work..
If that's not possible is there a way of getting rid of the '?' in the url
when people have cookies enabled? When cookies are not enabled the sid will
follow the '?' in the url since currently all my links have ?=sid? at the
end.. So for example:
a href=login.htm??=sid?Please login/a
As you can see there will always be the '?' at the end of login.htm.. When
the surfer has cookies off it doesn¹t look bad, but when he has them
enabled.. It just looks strange :)
Thanks!

Re: [PHP] Still REG EX
Have a look at this:
function ValidateUrl($url) {
// Check the syntax
if
(!preg_match(!((https?|ftp)://)(www\.)?([a-zA-Z0-9/\-]*)+\.([a-zA-Z0-9/\-]*
)+([a-zA-Z0-9/\-\.]*)?!, $url)) {

}
// If it's correct, then try and open it
if (!@fopen($url, r)) {
return false;
}
return true;
}
if (!ValidateUrl(http://www.yoursite.com;)) {
echo Invalid url;
} else {
echo It's there.;
}
Not particularly clean, but it seems to work ok. Will check for http,
https, ftp, followed by an optional www. followed by numbers, digits,
hyphens etc. If it gets passed that check, then the function then attempts
to open the url. You may need to play around with it a little...

Subject: [PHP] Returning mutliple matches of a regex with preg_match()
Hello all
I have been scratching my head for the last two days about this regular
expression problem. I would be really VERY happy if someone could help
me!
I have the following text in the file 'text.htm', for example:
--
BLOCKQUOTEP
Cow, Cow, Cow, Cow, Cow
Cow, Cow, Cow, Cow, Cow
Cow, Cow, Cow, Cow, Cow
a lot of lines
/P/BLOCKQUOTE
pboring stuff - we are not interested in this/p
BLOCKQUOTEP

Chicken, Chicken, Chicken
more lines
/P/BLOCKQUOTE
pmore boring stuff - we are not interested in this/p
BLOCKQUOTEP
Rabbit, Rabbit, Rabbit, Rabbit
/P/BLOCKQUOTE
peven more boring stuff - we are not interested in this/p
BLOCKQUOTEP
Pig, Pig, Pig, Pig, Pig
/P/BLOCKQUOTE
--
I want to return all the stuff between BLOCKQUOTEP ...
/P/BLOCKQUOTE
in an array. One element per match. For example, for the above text, I
would
like to get back an array back like this:
array(
Cow, Cow, Cow, Cow, Cow Cow, Cow, Cow, Cow, Cow Cow, Cow, Cow,
Cow, Cow a
lot of lines,
Chicken, Chicken, Chicken Chicken, Chicken, Chicken Chicken,
Chicken,
Chicken more lines,
Rabbit, Rabbit, Rabbit, Rabbit,
Pig, Pig, Pig, Pig, Pig
)
I have been trying to do this with (many variations of) the following
code:
--
?PHP
// open file
$fd = fopen (./text.htm, r);
// load contents into a variable
while (!feof ($fd))
{
$content .= fgets($fd, 4096);
}
// close file
fclose ($fd);
// remove char returns and co.
$content = preg_replace(/(\r\n)|(\n\r)|(\n|\r)/, ,$content);
// match agains regex -- this does not work correctly
if
(preg_match(/BLOCKQUOTEP(.*)\/P\/BLOCKQUOTE/i,$content,$matche
s))
{
echo pre;
var_dump($matches);
echo /pre;
}
?
--
For the above, var_dump() returns this:
--
array(2) {
[0]=
string(556) BLOCKQUOTEP Cow, Cow, Cow, Cow, Cow Cow, Cow, Cow,
Cow,
Cow Cow, Cow, Cow, Cow, Cow a lot of lines /P/BLOCKQUOTE pboring

/P/BLOCKQUOTE peven more boring stuff - we are not interested in

}

Clearly not what I want.
Is my approach here incorrect? Or is it indeed possible to construct a
regex
to do what I want (with just one pass of the text)?
Thank you in advance.

[PHP] Re: Yet another regex question
Hello, Simon
Simon H wrote in message...
I'm trying to validate an input form, for database INSERT/UPDATE. I'm
looking for a couple of Techniques and I cant seem to find examples
anywhere:
1. Validate Alpha Text with spaces, such as NAME, CITY, STATE, but limit
the
length of each one separately, and remove unwanted characters like
'@!£$%^*() etc that might mess with the SQL.
Alright, clearup before you insert. That's my first bit of advice.
Here's a function for you.
function ClearUnwanteds($string) {
$string = preg_replace(/[^a-zA-Z0-9 ]/, $string);
$string = trim($string);
return $string;
}
This will replace (when invoked, like this: $string =
ClearUnwanteds($string) ) the characters you don't want, and then trim the
string. Then you can do:
if (strlen($string) /*enter minimum characters*/) {
// error
}
2. As above but alphanumeric with spaces etc. for say ADDRESS1 ADDRESS2
POSTCODE, etc.
Hmm.. isn't that what you wanted for your previous problem?
3. Validate DATE/TIME input to DD-MM- HH:MM:SS or D-M- H:M:S, or
any
combination, but only allow valid dates and times, or as close to it as
possible.
You should pick a format, and stick to it, then form a function around the
format you've chosen - or look up some classes available for use on the net.
Since you're storing the data in a MySQL database, you may as well check the
date in the format it's stored in your db in the date (-MM-DD) or
datetime (-MM-DD HH:MM:SS) formats MySQL uses I would go for select
boxes with the day, month and year specified, then use something like
checkdate() to check the date on these variables, then merge them
(can't think of a better word) to form your date - i.e.
if (CheckDate($month, $day, $year)) {
// -- if ok, $date = $year . - . $month . - . $day;
} else {
// failure
}
I have formed some functions that I've made available (somewhere), if you
need them I can probably drag them out and give you the urls.
4. Validate MONEY input...numeric with 2 decimal places only.
What currency? You're using a UK email address, but you've specified
STATE in one of your other regex wanteds, which is more typical of the
US address format.
Also, what is the best way to allow some fields to be empty, like
ADDRESS2,
but if they have data, then validate it.
if (!emtpy($field)) {
// perform validation.
}
???
I've tried several times to do these myself using eregi, but when I test
it,
the validation fails in some way...I'm shooting in the dark tho, and don't
really understand regex just yet, or probably the majority of PHP for that
matter.
Well, ok. But that's what you're here for, right? :)
Thankfully I've got an email one... it was easy to find, since that's what
all examples are geared for. My application is for updating a DB with
SQL,
and I cant find anything suitable.
Then your'e looking in the wrong places (and more specifically, looking at
things from the wrong perspective - regex's can be applied to pretty much
anything (though, there are occassions when using them is overkill))!
If there is any other advice for data input into DB's regarding security,
I'd really to hear it.
bvr's advice is good - read up on what he's suggested. :) Oh, and there are
the manual entries (for which I've forgotten the addresses).
Good luck!

[PHP] Re: Yet another regex question
Hello again,
This is excellent. If you don't mind digging out your functions, I'd much
appreciate it...
I'll have a look tomorrow.
The previous question was for alpha only, no numeric ...names dont have
numbers, but addresses usually do.
Alright, well:
[a-z] matches a through z
[A-Z] same, upper case
[0-9] yup, zero through 9
[ ] space
Look up the pattern modifiers, and the pattern syntax in the pcre section of
the manual):
if (!preg_match(/[a-zA-Z]+$/, $name)) {
// $name doesn't consist of characters within a-z or A-Z
}
I'd got kinda mixed up there on the date thing...lol. I have a javascript
date picker thingy, but unfotunately it drops leading zeros on the dates
and
times. I think, however, your suggestion if pulldowns is much safer, but
the date will be for MySQL or MS Access. I think -MM-DD HH:MM:SS, as
you suggested would be the answer, and I'll try to add the time into the
$date variable.
Just out of curiosity, what are you using this for? I mean, you might be
doing more work than you need to be doing.
The currency is irrelevent here (although will UK£). I just want the 2
decimal places money format. I have STATE above because thats what the
field is in the databaseOn display it says state/county.
I see - check out number_format(), printf() and sprintf() in the manual -
this might already solve some of what you want, though I can't see why you'd
need two decimal places in a regex check :
$19.95 // one decimal
£19.95 // same
£19.95.1 // what the? :)
Can you elaborate as to why you need 2?
Alright, time for sleep.
Try and give a bit more info as to what you're using these for (and where,
if it's currently being used) your code is failing..
:)

[PHP] Re: Ereg/replace/i/ or something ??
Hi Bart,
I want to check the data from a form-field if it excists only of digits
(0-9) and nothing else.
How do I use the ereg()-function for this?
Well, I prefer the preg_functions
if (!preg_match(/^[0-9]{10}$/, $string)) {
// contains stuff other than numbers, or is less than 10 digits in length.
}
You could also just use is_int()
http://www.php.net/manual/en/function.is-int.php
and strlen()
http://www.php.net/manual/en/function.strlen.php
ereg([0-9],$cust_tel, $cust_tel);
It is also to turn it around but then the pattern will get larger because
it
has to contain:
/ '.,-)(*^%# a-z A-Z and so on...
The field has to be 10 digits long and has to contain only digits!!!
Huh?
If you just want digits, then where've those other patterns come from? Do
you mean you want anything BUT numbers?
Ok:
if (!preg_match(/^[^0-9]+$/, $string_without_numbers)) {
// string contains numbers
}
otherwise, please clarify.

[PHP] Re: Help with regular expressions
Hi Daniel,
José daniel ramos wey ...
Hi! I´m new to regular expressions, and it seems to be an art to make it
work as expected.
I´m trying to remove all single-line comments from an string - that´s
everything after // to the end of a line. I expected that this would do
the job: ereg_replace(//[[:alnum:]]*\n,,$string), but it didn´t work.
Any tips?
First off, IMO, you're better off using pcre regex functions than the posix
ones:
http://www.php.net/preg_replace
?
$string = // line 1\nNormal line\n// line 2 with a few odd
characters\£$%^*()_\nAnother normal line.;
$string = preg_replace('!^//.*$!m', '', $string);
echo $string;
?
Your regex is basically saying this:
//[[:alnum:]]*\n
Match anywhere in the string (you have no anchor as to where the // should
start), consume anything that is alphanumeric (0 through 9, a through z), as
many times as they occur, followed by a new line. Thus, your regex would
consume stuff like this:
//sdfdfffsdfsdfsdd12345678900987sdfsdbfs
but not
//
sdfdfffsdfsdfsdd12345678900987sdfsdbfs
or
// this is a comment.
as for my example, I'm using exclamation marks as the delimiters, the m
modifier which matches $ at the end of every newline, and ^ at the start of
every new line.
So:
!^//.*$!m
Means
^ at the start of the line
// if there are two of these
.* match everything
$ up to the end of the new line
and replace it with nothing.
Check the pattern modifiers etc in the manual.

[PHP] Re: help using ereg_replace()
Hello Erik,
Hello everyone,
I am trying to learn how to use ereg_replace(), but I don't seem to be
doing it correctly.
$phone is a 10-digit string.
I want to perform the following:
$phone = ereg_replace(.{10}, [part where I am confused], $phone);
I would like the output to be
$phone = (555) 555-;
I would use preg_replace to do this.
?
$phone = 55;
$phone = preg_replace(/([0-9]{3,3})([0-9]{3,3})([0-9]+)/, ($1) $2-$3,
$phone);
echo $phone;
?
The parentheses in the first part of the expression capture what you want.
The stuff between the [and] is a characterclass (in this instance 0 through
9).
The stuff between the curly braces is min,max.
So.
([0-9]{3,3}) Match 0 through 9 a minimum (and max) of three times
([0-9]+) - match at least once.
Hence the number becomes:
($1) $2-$3
($1) = stuff in first parentheses (three digits) - this case, (555)
followed by a space
followed by the next three digits
followed by a dash
followed by whatever's left.
Note that in the second part of the expression, parentheses lose their
special meaning, and can be used as regular characters (as can the other
metacharacters).
You will want to make sure that the numbers when inputted are in the format
you want them when you bring them back out of the file / db whatever -
if (!preg_match(/^[0-9]{10,10}/, $input)) {
// We need 10 numbers!
}
Hope that helps.

Hi Erik, Thanks for the advice (and especially the explanation!) -- I note that you chose the Perl regexp engine rather than the e regexp engine (POSIX?). Quite a few people recommended O'Reilly's Mastering Regular Expressions over the weekend. Does anyone know if it covers the Perl syntax*? This seems like a good book to learn more. The book (though going into examples using perl mainly) gives you a general grounding in regular expressions - I learned php before perl, and javascript, though the book has equipped me equally well for all three.

I need a routine that will allow me to trap multiple br and/or line feed
characters and convert them to a constant number. As an example, let's
say
that you have text that has 10 carriage returns and/or line feeds. I want
to limit this to 3. So, I need to be able to parse the line to detect the
multiple control characters and convert the string to 3. So if the string
looked something like:
This is \n\n\n\n\n\n\n\n\n\n a test.
I would want it converted to
This is \n\n\n a test.
Conceivably, it could be
This is brbrbrbrbr a test.
I would want it converted to
This is brbrbr a test.
I know I could write a do/while loop, but I was wondering if there is a
way
using eregi_replace or something along that line?
Thanks!

Thinking about it, this would probably be even better:
$string = preg_replace(/(\n|br){3,}/i, \\1\\1\\1, $string);
This:
$string = This is a
\n\n\n\n\n\n\n\n\n\n\ntest\nTesting\nTesting\n\n123brbrbrbrbrbr
brbrbrbrbrSome more testingbrbrbrbrbrbrbrbrbrAnd
a little
morebrbrbrbrbrbrbrbrbrbrbrbrbrbrbrbrbrbr
brbrbrbrbrbrbrbrbrbrbrbrbrbrEven more.;
Then outputs as this:
This is a br /
br /
br /
testbr /
Testingbr /
Testingbr /
br /
123brbrbrSome more testingbrbrbrAnd a little
morebrbrbrEven more.
when echo'd with nl2br()
As a side note, does anyone know what's with the br tag changing to br
/? That's the way I've always used the line break tag for wml pages, but
hadn't realised that it's being written that way for standard html now. Is
this a change in spec?

[PHP] Re: about the replacing HTML code by another codes in a Forum ?
Hiya, well, you could replace all script tags with this regex: $string = preg_replace(/\/?SCRIPT.*?/is, , $string); But, if you're converting all and to their html equivelants (which you should be) using something like htmlspecialchars or your own regex, you shouldn't even need to do that. You might also want to think about strip_tags(), though again, I prefer just to convert the characters and not worry about it. as for your links, I'd rethink the user input and use something like [a=www.microsoft.com]Click[/a] ; // quick and dirty regex $string = preg_replace(/\[a=(.+?)\](.*?)\[\/a\]/is, a href=\\\1\ target=\_blank\\\2/a, $string); James Trongduc [EMAIL PROTECTED] wrote in message 001101c17341$b6de6060$1d0b10ac@d">news:001101c17341$b6de6060$1d0b10ac@d... hi, can anyone help me this ? 1) I made a simple forum, and it will allow the users to send their messages in HTML format. But I worried about the security of my website, so I removed all of the SCRIPT tags in their messages by placing /SCRIPT instead. (Because the users maybe use SCRIPT language=JavaScript, so I cannot replace SCRIPT exactly) Is it the best solution to protect my pages from malicious code ? (is it secure for my pages ?) Are there other ways that someone can use malicious codes in their messages without SCRIPT ? 2) In the case I do not allow the users send messages in HTML codes, I replaced (similar with phpBB code) : [a]=a href= [/a]= [//a]=/a example the content of message is : [a]www.microsoft.com[/a]Click here...[//a] ...will place a link to Microsoft.com, but the problems will happen when the users use only [a], or [/a], not use [//a] to close the link. Can anyone help me to fix this problem ? (is there another way to do this more simple ?) thanks very much... -- 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]
[PHP] Re: regular expression
Hello,
Galkov Vladimir [EMAIL PROTECTED] wrote in message

Need to remove all ../ /.. from user inputing string to prevent him
walking and creating filesdirectories where I don't whant see them/him...
The string:
$path =
eregi_replace('([..]{2,})|([./]{2})|([../]{3,})|([/.]{2})|([/..]{3})', '',
$path);
works good with any combinations ( ../../..qwert.txt = qwert.txt)
untill
somth like /../asd/../qwert.txt will be entered ...
(/../asd/../qwert.txt
= asdqwert.txt).
So the qwestion is how upgrade regular expression to remove all this
correctly (with all entered directory names but NOT assigned their names
to
file name...
Must do the operation:
/../asd//qwert.txt = qwert.txt
but not = /asd/qwert.txt or asdqwert.txt.ru
or
/../asd/../qwert.txt.ru = qwert.txt.ru
but not = /asd/qwert.txt.ru or asdqwert.txt.ru
Try this:
?
$string = /../asd//qwert.txt;
$string = preg_replace(/(\.*\/\.?)+.*?(\.*\/)?/s, , $string);
echo $string;
?
May need some tweaking, let me know.

Hi there,
I am camping with a little regular expressions problem...
Problem: I want to check if $variable begins with a * (star), and it doesn't
matter if it starts with plenty of spaces...
My solution:
ereg(^[:space:]*\*,$variable)
But, it doesn't seem to work with the space part... The regex:
ereg(^\*,$variable)
does work, but that doesn't include spaces at the start... How can I extend
this one so that it doesn't matter if there are a lot of spaces at the
begin?
Thanks in advance,
Leon Mergen

Re: [PHP] Re: syntax for checking if string contains something
Hey,
if (isset($submit)){
if (!empty($qty))
{ echo Please enter the quantity for your quotation enquiry.;}
When nothing was filled in for $qty the if condition did not prompt me to
enter a quantity.
This is wrong:
if (!empty($qty))
{ echo Please enter the quantity for your quotation enquiry.;}
You're checking to see whether or not qty IS empty, this statement checks
for when when it is NOT empty
if (empty($string)) {
// This is an empty string.
}
if (!empty($string)) {
// This is NOT an empty string.
}

[PHP] Re: mktime() problem
Hi James, I'm running 4.0.6 on a Solaris 8 box. The output given by echo mktime(0,0,0,1,1,1970); is 3600. Shouldn't it be 0? My box's locale is set to the UK defaults, so as I write this we are in daylight savings (GMT+1). Would this make a difference? (I have already tried I uploaded the same script to my server which is also running BST (GMT +1) : the output was as I expected, -3600 (we gained an hour, so had to lose it somewhere): are you sure your value wasn't minus 3600 also?
