to preserve line breaks when generating rtf documents from the text blob essays we have in the mysql db.

this is working fine. i have recently had some requests that we add the ability to preserve rich text formatting such as bold, underline and italics to the essay question text box. apparently, the mysql data type 'text' doesn't store rich text formatting such as bold and underline. specifically, i've seen some really nice javascript(?) rich text editors in some high end web based email clients - it would be great to duplicate this type of functionality in our app, as some people would really like to preserve italics and the like in their essays.
RTF is just plain text with special markup commands embedded in it. Mysql Text columns can hold them just fine.

You should translate <i> and <b> into the corresponding RTF tags and then your formatting will be preserved.

i was wondering if anyone has had experience with coding rich text text editors, or similar experience. if you have any advice for me, i'd really appreciate hearing from you
if you want a fancy GUI editor for your web page, that is not a PHP question. do a search for activex or java text edit widgets. most of them will convert to HTML though, so you'll still have to convert the html commands to RTF in your php script.

You can also use dhtml/js to code a html editor. But it will work in IE
only. Search for online html editor. See this
link:http://msdn.microsoft.com/library/default.asp
If you are developing for a organisation, the type of browser used is easy
to predict. If you are developing for the general public, there is of course
other browsers to take care of. Java will fit all kind of browsers (that
have java plugin) but it is usually very heavy for the client side.

Perhaps you should have a look at the source code of
the PHP-interpreter.

I used to program in C and when I wanted to use flexible
data structures like those in PHP I generally would use
doubly linked lists and trees of them etc. (Meshes are
much harder to maintain of course.) One can also use
hash-tables. But some things can be fast given a certain
implementation and others can be very slow. When you
have an unusual problem (and you seem to have) then
it's crucial to either control the mechanisms yourself
or to know how PHP does it (but you shouldn't count on
the fact that any internal mechanism will stay the same
over time).

As regards doubly linked lists (that I like a lot):
You can travel through such a list in linear speed,
but for example removing a couple of middle elements
will cost in the order of n*0.5 iterations through
the list (to find the first element to remove), so
repeatly removing elements will be very expensive.

Finding a single element in a doubly linked list can
be sped up using a hash-code table, but it also
makes things like renumbering numerically indexed
entries a lot harder (I think, I never used a
combination of these things.)

But it's hard to estimate these things. Merging two
already sorted linked lists into one takes linear
time of course. I once even deviced a quick sort
algorithm for doubly linked lists and was pleasently
surprised that it was possible. (Qsort is of order
n*log(n) unlike most sorting algorithms which are n*n).

You may also want to consider writing some kind
of underlying engine in C and then make it accessible
from PHP for easy scripting. Most programs spend
only 10-20% of their time in the fluffy code, which
can therefore be written in a programmer-friendly
language and 80-90% of their time in computationally
intensive code that had better be optimized for speed.

Years ago we would even hand-optimize the assembler
output of the C-compiler to make the kernel of an
application faster...

Greetings,
Jaap

Doubly threaded red-black trees are good for in order traversal and
arbitrary lookup. As with most structures that provide more speed, you
use more memory :)  O( lg n ) insertion, O( lg n ) deletion, O( lg n )
search. Threaded means the in order nodes are threaded into a linked
list. PHP I believe uses hashes of some sort, I'm not sure how they keep
track of the insertion order for doing a foreach loop -- I guess we
could look. On a more related topic: if he's happy with the unset()
function but wants the indexes renumbered, he could write a C function
which performs the renumbering. Should keep it relatively fast and
provide the option of renumbering -- or not.

Cheers,
Rob.

Well, I can't really help here without seeing some relevant code.  You may be right, 
and what you are doing does require no gaps in your keys -- but it may be that you can 
program round that more efficently than you can re-index the array when you delete a 
value.

That said, I'd answer your original question with:

    array_splice($arr, $n, 1);

which should actually be pretty efficient!


Cheers!

I'd like to ask then if the viewers could validate my
new approach or at least point ways of actually
implementing it.
Suppose I use Xerces and tidy to turn two html files
into two xhtml ones.
I'd like to remove the data found between the Tags and
generate two new files only with the scructure
elements (tables, Br, p and so on).
Then I could use regular diff from unix and if they
differ in more than X% I assume they are different.
Assuming that this approach is ok any tips regarding
the actual implementation ?  Any snippets of code
would be great.

Ive got a pretty simple script that runs at 5 past midnight. It grabs the local 
date/time and processes data based on the date/time. The problem is the date/time 
returned by the date() function is incorrect.

here is a sample script (not actual script running on server):
test.php
<?
$t = time();
echo "\n<br>timestamp = $t";
echo "\n<br>time = " . date("r", $t);
?>

if i run test.php via the web it produces the following output, which is correct:
timestamp = 1061443716 
time = Thu, 21 Aug 2003 15:28:36 +1000 

if i run test.php via the command line it produces the following output, which is off 
by 10 hours:
<br>timestamp = 1061443722
<br>time = Thu, 21 Aug 2003 05:28:42 +0000

has this happened to anyone before? what could cause the huge difference in time?

Im running PHP Version 4.3.2 on NetBSD 1.6

The reason for the difference is due to the timezone bit (or whatever it's
called..)

Note the +1000 in this line
        time = Thu, 21 Aug 2003 15:28:36 +1000 
and the +0000 in this line
        time = Thu, 21 Aug 2003 05:28:42 +0000
so both are actually the same times (bar a few seconds..)

But for the reason why one is showing GMT and the other Oz time, I don't
know...

HTH though

You need to set the timezone either system wide or within the
crontab, since crontab usually runs with a /bin/sh shell something
like:

TZ=Australia/Melborne
export TZ

You'll have to consult your system documentation to set it system
wide and to get the proper name of the TZ.

That should help ya.

It is definately a system problem. I actually looked at the source
code for the date() function and all it does is get the time
information from the systems localtime call.

A 'man localtime' might reveal more information about how the
timezone needs to be set.

Although the environment setting for the cron fle should work fine,
you could even go so far as setting that in your php file:

  putenv('TZ=Australia/Sydney');


hth,

Try using date from the command line and see what it produces.  If you do
something like:

    date '+%c'    # might be different -- check your man date

and it produces the wrong time, then you would be armed with sufficent
evidence to go to the system's admin and say "oh no it **** well isn't --
look!"

A simple loop through the array:

what is happening why am i keep getting these from php ppl ?

i have recieved them from rasmus and anyone with a php.net domain aswell as

Here's your reason:

"... the variation on the latest version [of SoBig] means that anyone who
has a well-publicized email address is getting inundated. Previous versions
simply went through Outlook addressbooks and sent the virus on (while also
attaching another email address on as the return address). This version also
looks through the victim's cached webpages, so any email address found on
websites that many people visit have discovered that their getting hundreds
or thousands of virus emails."

Hi,
I am trying to upload something into a directory on my server but always i
am getting a permission denied ONLY from this server...i have tried it on 2
other servers and they seem to be working fine but i have to get it working
on this server as this server is the fastest and our production server.

I have looked at the folder permissions and CHMODED/changed them from 644 to
766 and finally 777 but am getting the same error, i then had a look at the
php info file (http://jumac.com/phpinfo.php) and i see file_uploading is set
to 1 and 1, safe mode is off, i am not too familier with file uploading so
is this right? if not, how can i change it? hopefully via a .htaccess as I
dont have access to the php.ini file directly.

Let me again point out that this problem only seems to be on this server,
the scripts including the upload is working perfectly on the other test
servers/sites.

Kindly reply,
-Ryan A.

--- Begin Message --- Hello, It could be because your server is using some out of the box virtual hosting setup like ensim or cpanel. This usually means your home path is not what it appears to be. That in turn means that if you use absolute pathnames with your file upload handler it's bound to fail. So you will need to double check your paths.

For example the phpinfo you refered to shows that the script path is /usr163/home/r/y/ryanknig/public_html/ and my guess is that this is not what appears as your home page. (eg you might know it as /home/ryanknig/public_html )

Confused? these lousy virtual hosting setups are very confusing indeed. Most people get by with them for static websites but when you do file handling and stuff like that all kinds of complications pop up.

Hi!

Today I encountered a very strange POST problem. On FreeBSD4.8-stable I
compiled apache 1.3.28 (using ports) and php4.3.3.r4 (also using ports). It
was compiled with the following options:
'./configure' '--enable-versioning' '--enable-memory-limit'
'--with-layout=GNU' '--with-zlib-dir=/usr' '--disable-all'
'--with-regex=php' '--with-apxs=/usr/local/sbin/apxs' '--enable-bcmath'
'--with-bz2=/usr' '--with-crack=/usr/local' '--enable-ctype'
'--with-curl=/usr/local' '--enable-dbase' '--with-dom=/usr/local'

'--enable-ftp' '--with-gd' '--enable-gd-native-ttf' '--enable-gd-jis-conv'
'--with-freetype-dir=/usr/local' '--with-jpeg-dir=/usr/local'

'--with-xslt-sablot=/usr/local' '--with-zip=/usr/local' '--with-zlib=yes'
'--prefix=/usr/local' 'i386-portbld-freebsd4.8'

(as it going to be multi-purpose web serwer).

In this environment I tried to run one of ours applications that runs
without any problems on a machine with apache1.3.27 and php4.3.2 and spoted
that in certain circumstances the POST variables are empty.

The post form consists of 2 input lines and a submit button (simple login
page). If I enter certain texts in both lines and press the submit button I
see nothing got set - with others texts - no problem - everything works
perfectly.
However there is a clue - if I add phpinfo to the script that is processing
POST  - some variables show up (but not all). 

Does anybody have any idee what causes this strange behavor? I'm sure the
scripts are exactly the same on both machines. 

regards
przem

David, this is exactly what I was so poorly trying to get at ;) I just have
to consider my found result set of rows as array('A', 'B', 'C', 'D', 'E',
'F', 'G', 'H') Your example renders the data in the way I was looking for.
Thanks!

Petre, you were right also. I was able to get my pseudo method to work,
though it was a mess ;)  Your example has provided some guidance in
re-thinking. Best Regards.

Hi,
I'm trying to filter a word - in this case - called badword1 - to be
replaced
with asterisks.

Listed below is my .html form and .php receiving script.

I've also added the same script which gets a hardcoded string.

In the first example, the output still shows the original message _without_
replacing the badword whereas in the second example with the hardcoded
string - it is getting replaced with *****.

Any assistance would be greatly appreciated.
Thank you.
Tony Ritter
