Re[2]: [PHP] preg_replace: avoiding double replacements

[Andre Polykanine]

Hello Jim,

That might work for that particular example, but I have utf-8 strings
containing different characters of different alphabets, so neither
str_replace nor strtr work...
Thanks!

Well, for the example you gave, why use regex?  Check this out as an example.

 and OLDTAG with the 
';

$regex = array(
'/BOLD/i',
'/OLDTAG/i',
);
$oldtags = array(
'BOLD',
'OLDTAG',
);
$replacements = array(
'',
'',
);

# Original String
echo $text."\n";

# After regex is applied
echo preg_replace($regex, $replacements, $text)."\n";

# After plain tag replacement happens
echo str_replace($oldtags, $replacements, $text)."\n";

?>

See if that works for you.

Use better regexes: either match for word endings or use a delimiter
in your markers (i.e. ###BOLD### instead of BOLD).

[PHP] Authentification and session management

[Michelle Konzack]

Hello PHP-Community,

I am PHP programmer since many years and over the years, I have reinvent
the wheel in authenification and session management at least 30 times.

Yeah, whenever a new project started, I had to reinvent the wheel.

So my question now is, is there a proven and secure framework which  can
be used?

My main problem is, that we (anything ISP  related)  authenticate  using
PAM+PostgreSQL while the normal Web-User stuff is authenticated directly
with a Virtual-DB based on PostgreSQL.

Another thing I like to implement in my scripts, that users can at there
implicit choice be permanently connected without using a password.  Also
the script shoud detect, whether a user is connected trough a dynamic IP
or a fixed one and sugegst a security level.

I am already detecting the IP from the login and many customers  (mostly
from ) have static IP's.

Thanks, Greetings and nice Day/Evening
Michelle Konzack

Re[4]: [PHP] preg_replace: avoiding double replacements

[Andre Polykanine]

Hello Peter,

Hm... I see I need to specify what I'm really doing. Actually, I need
to change the letters in the text. It's a famous and ancient crypting
method: you divide the alphabet making two parts, then you change the
letters of one part with letters for other part (so A becomes N, B
becomes O, etc., and vice versa). it works fine and slightly with
strtr or str_replace... but only if the text is not in utf-8 and it
doesn't contain any non-English letters such as Cyrillic what I need.
What my regex does is the following: it sees an A, well it changes it
to N; then it goes through the string and sees an N... what does it
do? Surely, it changes it back to A! I hoped (in vain) that there
exists a modifier preventing this behavior... but it seems that it's
false(
Thanks!

Hmmm, what comes to mind is using your string as an array and
translating one character after another, building your output string
using a lookup table. Not entirely sure how that will play with utf8
characters, you'd have to try and see.
 I don't think you'll get any of PHPs string functions to do the work
for you - they'll do the job in serial, not parallel.

Peter

I recently heard about a PHP-based authentication system called Sumo. It
might be what you need to stop re-inventing them darn wheels!

If you're wanting to use the Caesar cypher (for that's what it is) then
why not just modify the entire string, character by character, to use a
character code n characters ahead. For example, a capital A is ascii 65,
you want to change it to an N to add 14 to that. Just keep n the same
throughout and it's easy to convert back.

You probably overlooked the part where the OP points out he's not
using ascii but utf8. If it was just ascii, using str_rot13() would be
the weapon of choice I'd say (note that adding 14 to every character
of an ascii string will turn lots of it into gibberish - you have to
wrap round when you reach a certain point).

Peter

I gave the example as Ascii because I knew the code for A off the top of
my head, I don't see a reason why it won't work for utf, the characters
still have incremental codes.

Also, is gibberish really an issue to worry about? The Caesar cypher is
already rendering the string unreadable.

You normally want output in the same range that you encode from (i.e.
you're remapping within the alphabet, not within the entire range of
printable characters) if you're doing a caesar/rot13.

The modified time should be the modified time of the file when it was
added to the archive.

If you touch() the file before you add it to the archive, then the new
time will be used.

But the phrase ", so each file preserve its modified time", suggests
that the modified time is NOT remembered.

If so, I would consider that a bug.

But, if you are using extractTo(), then you could use statIndex() to
read the archive to find the modified time and then to touch() the
created file with that time.

Hello PHP-Community,

I am PHP programmer since many years and over the years, I have reinvent

Yeah, whenever a new project started, I had to reinvent the wheel.

So my question now is, is there a proven and secure framework which  can
be used?

My main problem is, that we (anything ISP  related)  authenticate  using
PAM+PostgreSQL while the normal Web-User stuff is authenticated directly
with a Virtual-DB based on PostgreSQL.

Another thing I like to implement in my scripts, that users can at there
implicit choice be permanently connected without using a password.  Also
the script shoud detect, whether a user is connected trough a dynamic IP
or a fixed one and sugegst a security level.

I am already detecting the IP from the login and many customers  (mostly
from ) have static IP's.


Why don't you take one of those wheels you created and make it work with 
a simple configuration and voila, you have a class or library that can 
be used in all your projects. It should be as simple as it sounds.


Cheers,
Rob.

You normally want output in the same range that you encode from (i.e.
you're remapping within the alphabet, not within the entire range of
printable characters) if you're doing a caesar/rot13.

[PHP] html analyzer

[Rene Veerman]

Hi.

I'm trying to build a html analyzer that looks at natural words in html text.

I'd like to build a routine that walks through the HTML character by
character, but i'm not sure on how to properly walk through escaped "
and ' characters in javascript or other embedded languages. Skipping
the first " and ' is no problem, but after that, the escaped " and ',
they can get difficult imo.

If you have any ideas on this i'd like to hear 'm..

Better try something that is already done. HTML parsing is not that
trivial. If the HTML you are parsing is malformed, things get worse.

You may want to try this HTML parser package. It can parse HTML, CSS,
DTD, etc.. in pure PHP. No special extensions required. It can tolerate
malformed HTML and even filter insecure HTML and CSS that may contain
dangerous Javascript. Actually it was done mainly for that purpose.

[PHP] php photo galery

[David Mehler]

Hello,
I've googled for this and tried some downloads but not finding what
i'm looking for. A site requirement is to have a photo gallery. These
user's are not very technical so i thought about getting a galery with
the ability to upload photos via a browser, I would also like thumb
nails, and the ability to have an alt text attribute with the photo
and a longer description of the picture, for accessibility reasons.
If anyone has anything similar to this please let me know.
Thanks.
Dave.

Something like this wouldn't be too hard to put together.

A form with a  element could handle the image upload
and text part. If they need to upload multiple files then you could
either use several input elements or a multi-upload option, although the
latter aren't very accessible at all I've found, which seems to go
against one of your requirements.

I assume the need for multiple galleries, and further assume that you
already have a way that you are distinguishing users. Just use this
identifier against each image to denote a gallery. A database can easily
be used here to not only identify the gallery an image belongs to but
the user who uploaded it, and what galleries the user has rights to,
etc.

Creating thumbnails is also a doddle. I've just written up a function I
wrote for http://www.vicestyle.com which creates thumbnails in any size
you want from any image without distortion using a smart crop technique
at http://www.ashleysheridan.co.uk/coding/php/Smart_Image_Resizing .

SlidesShowPro Director:



You could use the Director API and create a PHP gallery with your own
code, or you could use the SlideShowPro flash player.

The Director interface is very easy to use. For a nominal fee, you can
have SSP site host Director for you, or you can host the software it
yourself.
