[PHP] Re: Search/Regular Expression problem
If you're splitting them up with preg_split(), you can combine them with
implode(). Something like
$foo = .* . implode(.*, $words);
Or don't use an array at all. Just replace anything that's not a valid
search character...
$regex = preg_replace(/[^A-Za-z]/, .*, $search);

Hi,

I am making a search engine and I would have the user to type a sentence
to search for.
Let's say it is stored in $search.
My search enginue will bring up a result IF and only if ALL of the words
in
$search exist in the result. For example
if
$search = Vax Useful Commands
Then the result is only true if (eregi(.*Vax.*Useful.*Commands.*,
'possible result')) is true
Now, I don't know how many words there are in $search initially. How do I
do a search like that? I mean if I know $search is 3 words then I can do
$words = preg_split(/ /, $search);
if (eregi(.*words[0].*words[1].*words[2].*, 'possible result')) {
.
}
Even if I know how many words there are, everytime the number of words in
$search can be different.
Can anybody give me any ideas?
Thanks a lot

I wasn't sure on the padding scheme that mcrypt uses, so if it is indeed zeroes, you're probably fine. That might not always be the case depending on the padding scheme used (such as not having a padding scheme at all), but since mcrypt obviously does, things should be fine. As to the garbage that's being appended, could it possibly be due to some thread-safety issues? libmcrypt is thread-safe, but I believe there's an additional configuration parameter needed for safety. (Not entirely sure on that. Are you using a threaded web server?) However changing now will mean handling some historical data differently somehow. :( And storing an IV for each record would of course increase the data size. It wouldn't be that hard to convert.

[PHP] Re: occasional mcrypt problems
Try using a different block cipher mode. When encrypting with ECB, as you
said, your plaintext must have a length that is a multiple of the blocksize
for the cipher. If it's anything less, you're going to get some garbage at
the end of the decrypted ciphertext. I believe that mcrypt uses zeroes
padding for ECB mode.
You might want to try one of the other block cipher modes, like CBC or CFB.
This will require that you use random IVs for each encryption, but it's
much more secure than using ECB mode. Even though you create an IV in your
code below, ECB mode ignores it -- if you encrypt the same plaintext
multiple times using the same key, you'll end up with the same ciphertext.
With random IVs and the proper mode, this wouldn't happen. This will
require that you store the IV for each encryption along with the
ciphertext, but that's fine, as storing the IV along with the ciphertext is
not a security problem.
I'm not sure what mcrypt uses for padding on it's various block cipher
modes, but it might help. It'll be more secure than ECB, at any rate.

It appears in fact the same way as the problem I first experienced, when
the database field was not big enough to store the encrypted text (which I
discovered takes a multiple of the blocksize, so it is usually bigger than
the original string). However the blocksize is 8 and to provide a safety
margin all the fields to be encrypted have 10 extra characters in them
(varchar fields).
So far this happens on at most one field in a record, perhaps on less than
5% of the records. At first I was thinking maybe the addslashes() was
adding text but MySQL should be stripping that out before entering it into
the database, right? Also I can't seem to duplicate this by entering the
same values in the form again.
Any suggestions? Here is my encryption code:
$hrkey = '$R^a$nd()M%'; // changed text
$td = mcrypt_module_open(MCRYPT_TRIPLEDES,'', MCRYPT_MODE_ECB, '');
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), 99);
//changed the number
$ks = mcrypt_enc_get_key_size ($td);
$key = substr(md5($hrkey), 0, $ks);
mcrypt_generic_init($td, $key, $iv);
$CreditCardNumber = addslashes(mcrypt_generic($td,

[PHP] PHP crypto extension news
Since I just finished a pretty major source overhaul of the cryptopp-php extension, I figured I should make a little announcement, as this is oh-so-exciting news. Recently, Wei Dai released Crypto++ 5.0, which was pretty much a complete re-write of the public domain Crypto++ cryptography suite. In turn, I updated the cryptopp-php extension, hopefully for the better. The changes to this version, 0.0.9, are numerous, but the highlights are... - new padding schemes on block ciphers. In previous versions of cryptopp-php, you didn't get to choose your padding scheme -- you were stuck with whatever the default was for the block cipher mode. Now you can pick from PKCS#5, zeroes, one and zeroes or no padding at all. New functions to control this new ability were added: cryptopp_set_padding(), cryptopp_get_padding() and cryptopp_get_padding_name(). - keyed hash message authentication code algorithms were added. Basically, a HMAC is just a hash that uses a secret key. New HMAC algorithms include MD5-HMAC, RIPEMD-160-HMAC, etc. New functions to set HMAC keys were thusly added: cryptopp_set_hmac_key(), *get_hmac_key(), *set_hmac_key_length() and *get_hmac_key_length(). - a modified ARC4 algorithm was added. - the MD4 hash algorithm was added, although it should only be used when you really, really need it, such as for compatbility with other programs, as it is known to be cryptographically weak. - changes in the Crypto++ library itself have forced me to remove the Sapphire stream cipher and hash algorithms, but since I doubt they were used much, that shouldn't be much of a problem. - everything is for the most part backwardly and forwardly compatible with previous versions of cryptopp-php, with exceptions being noted in the manual. The only real differences you need to worry about are the block cipher padding schemes you're using and the SKIPJACK changes and SAFER-* changes. As always, cryptopp-php works on most UNIX-like systems as well as Microsoft Windows systems, and has been tested with Linux (kernel 2.4.18 and 2.4.9), Solaris 8 (SPARC) and Windows 2000 Professional. Source code and Windows DLLs are available under a BSD-like license at http://www.tutorbuddy.com/software/ This version should be considered somewhat unstable, so if you're worried about that, use version 0.0.8. There are a few known bugs in Crypto++ 5.0 that have been fixed in CVS -- they shouldn't affect cryptopp-php in any way, but there may be bugs in my code that haven't been weeded out yet, as this version hasn't been tested and is a near-total re-write from 0.0.8.

[PHP] Re: Session's is slowing the page ??
It might have something to do with the way the session extension in PHP performs garbage collection. There's a setting in php.ini that basically controls how often garbage collection is performed. The value is a percentage, and determines how often the GC should be done over a random number of session_start() requests. If GC is invoked, the garbage collector will start to delete all of the expired session files in your session directory. If there's a lot of them, it might take longer to load the page that the garbage collection was started on. Since the garbage collector is called at random based on the aforementioned setting, not every page will be affected.

You could use a transaction block if your database supports it, or just use
some sort of auto-numbering field, such as SERIAL in Postgres,
auto_increment in MySQL, etc. Then you wouldn't have to worry about
retrieving the next cno before inserting a new row.

RE: [PHP] Mcrypt: Blowfish or Twofish or no fish? part 4
I always hate mentioning this 'cause I feel like an attention whore or something, but nevertheless, I can't get the thing tested thouroughly without a bit of whoring... I've been working on a crypto extension for PHP for a while now, and since you guys seem into the crypto thing, you might like to check it out. It's not really meant to be a replacement for mcrypt/mhash or anything, just as an alternative. (One advantage is that it works on Windows as well as UNIX, and I believe the native, non-cygwin win32 port of libmcrypt/libmhash are no longer maintained.) Anyways, if you're at all interested, see http://www.tutorbuddy.com/software/ It supports pretty much all of the algorithms mcrypt and mhash do, plus a few more. (30-some block and stream ciphers, the usual block cipher modes, and 17 hash/checksum algorithms altogether.) Again, I hate the self-promotion, but as you all probably know, cryptography is useless unless it's been tested, studied and proven to be effective.

Re: [PHP] Making Multiple Pages
You should also add an ORDER BY clause in there, as the SQL standard doesn't guarantee the order that rows are retrieved in. There's a chance that you'll get, say, 20 rows on the first page, go to the second page and get some of the rows you've already seen on the first page. If you use an ORDER BY, you'll at least guarantee that you'll get them in the same order each time. J Kevin Stone wrote: $query = SELECT * FROM mytable LIMIT $i, 20; Where 20 is the number of rows to retrieve and $i is the starting row.

Basically, the Zend Engine is kind of like a macro scripting engine that PHP runs on top of. You can actually remove the Zend Engine and use it in other applications, like a macro engine for a work processing app, for instance. The Zend Optimizer isn't a part of the Zend Engine or PHP; it's an extension that you can download from www.zend.com. It isn't part of the standard PHP build or distribution. To duplicate the error I posted, get PHP 4.2.1 and the Zend Optimizer. Install both, then follow the directions that accompany the ZO to enable the Optimizer.

Linux is a form of Unix, one that is available free, as in it costs nothing, you are free to copy it and use it on as many computers as you like, and you can, if you are so inclined, make changes to the operating system as the full source code for the kernel is available to you. There are many forms of Unix, such as Sun's Solaris, HP's HP-UX, Digital UNIX, any of the *BSD systems, and Linux. Linux is just another form of Unix-like system. There are other freely available Unix systems, like the BSD systems (OpenBSD, NetBSD, FreeBSD), while other ones you usually have to pay for, and likely won't get complete access to the source. (Some are in-between, like Solaris, which you can download for free under certain circumstances, and you can get the source code, but you can't really distribute changes to the OS.) As for the most common Unix, these days it feels like Linux, 'cause it's all the rage, but the most common on the big-ass servers are the proprietary Unices, like Solaris. Apache isn't a Unix system at all, it's just a web server, like Microsoft's IIS. Apache can be used on pretty much any Unix system, and can even be used on Windows platforms. (Although it's generally more stable and faster on Unix systems.) If you're really new to Unix systems (and it sounds like you are) pick up a Linux distribution like Mandrake, RedHat, or SuSE, as they're generally the easiest to install. Once you get used to Unix-like systems, you can generally move between them fairly easily, although there is a learning curve. (For instance, while Solaris and Linux are both Unices, there are quite a few differences, but if you can get used to one, it makes learning the other relatively easy, versus only knowing Windows or whatever.)

An easier way to do it might be to use HTTP authentication with apache
using .htaccess and .htpasswd files, which can be placed in the secure
directories. (Or use one global .htpasswd file and have all .htaccess files
point to it.)
Another possibility would be to set up two PHP scripts, one being some
kind of form to enter a username, password, etc., and another to check the
input and act as a pass-thru for the file to be downloaded. The second
script could look something like this (obviously simplified):
if ($authenticated)
{
header(Content-type: whatever/text);
readfile($filename);
}
else
{
print You can't download this.
}
Which you would call as something like:
http://www.example.com/path/download.php?filename=somefile.txt
Obviously, you need to take care of a few security problems, like making
sure they don't do something like
http://www.example.com/path/download.php?filename=/etc/passwd
And you'd have to make sure the file exists and such before sending it out.
And determine the MIME type of the file. (I usually do this by extension.)
But overall, it would work. I have a similar script, minus the
authentication feature.

Suggestion: - When the user triggers the event, store their user name, email or whatever along with a timestamp in your site's database (if it has one) or in some text file some place. - Write a cron script that runs every five minutes, every minute, every hour, whatever. When this script runs, it reads the aforementioned database, text file, etc. and checks the timestamps and the user data. - If the data found by the above script (the timestamp and the user data) matches a certain criteria (i.e. the timestamp is 5 hours old, or whatever your delay is) and sends out the email appropriately, then deletes or otherwise updates that record, so it doesn't try again when it runs the next time.

Re: [PHP] good practice
The only real security problem is that if the file isn't parsed and it's in the web server's document path, somebody can just go to http://www.example.com/include/config.inc and see the entire contents in plaintext -- passwords and config options galore. However, sticking those .inc files outside of the web server's document path or otherwise cutting off access to those files makes things a lot safer. When I met Rasmus at a seminar a few months ago, he mentioned that he kind of started the whole .inc thing with included files, but he was astonished how so many people followed his convention without realizing that somebody could look into the .inc file so easily. When he was going it, he always explicitly denied access to those files through a Files directive in Apache's httpd.conf file, which nobody else bothered to do. So if you want people to view those files and all of the code in them, go nuts. Otherwise, you'd better somehow cut off access to them. (Personally, I use an include directory and use a .htaccess file to limit access.)

Or put them outside of the web server's document hierarchy. I'd feel safer with that than naming them with a .php extension. If they can still be executed by PHP using a GET request, then something could still be output to a user's browser. (Likely unintentionally, of course, but still...) Plus, if they're large enough include files that include a whack of other files, then why bother wasting CPU cycles on something that doesn't need to be processed in the first place?

RE: [PHP] Search Engine
PHP isn't totally bad for a search engine. Here's my story. I was in a bit of a predicament when I first started work, because I had to develop a search engine for online video objects. My company is essentially a video re-purposing venture, where we take reams of analog, tape-based videos, encode them into something like MPEG or ASF or whatever, create clip indexes (i.e. a 30 minute clip is broken up into 10x 3-minute clips, with each clip described and categorized) and provide a search engine and interface to watch clips or videos on the web via a broadband connection. (An added bonus is that you can create your own video via personal playlists -- you can take 10 different clips from 10 different videos and run them together into one playlist, all online. In a few months, you'll be able to create your own clips if you don't like our predefined ones.) Anyways, the search engine thing was my deal. I'm the only programmer (*period*) on our team, and I basically had to write a search engine, web site backend, admin interface and all that jazz for our app alone. I was hired March 6, 2001 or so, and I had until, oh, April 15, 2001 to do it. Plus there were a few conditions -- like, it should be portable and inexpensive. PHP seemed like a good choice -- it was portable (Win32, *ix, whatever), it was cheap ($0) and it isn't too bad for rapid development. So off I was. I did manage to finish the search engine and back end by April 15, but it was a mess. It wasn't exactly a stellar search engine, but more of a proof of concept, which was the whole point of the project -- to show that we could provide high quality streaming video through a browser with a relatively good interface. After the proof-of-concept project, we started to get serious, and I dropped most of the code base and started again from scratch. Pretty much the entire search engine now is in PHP, with the sole exceptions being the keyword indexer (Perl, as PHP was a lot slower doing the indexing) and a few extensions to the PHP engine. The search engine itself is fairly fast -- it can do a keyword search on a collection of nearly 8,000 video objects in an average of 0.02 to 0.20 seconds or so, depending on the complexity of the query. It's features include: * Boolean-type searches. Okay, not really, as in you can't use AND, OR and NOT, but you can use +/- style prefixes like in mnoGoSearch and whatnot. Words are automatically OR'ed, +'d words are AND'ed and -'d words are NOT'ed. * Decent search times. On a PIII 500 with 128 MB of RAM, it still averages less than 0.20 seconds for a collection of 8,000 video objects and over 100,000 keywords. * Filtering. We're mostly an education-based site, so you can filter by things like subject (Physics, Chemistry, etc.) and grades (Kindergarden, grade 10, college, etc.) * Spellchecking and somewhat fuzzy searches. Spellchecks work okay, but the fuzzy searches is kind of lame. (Porter stemming.) I might shoehorn in something like Metaphone-type stuff eventually. * Search ranking. Yes, keywords are given weights, everything is ranked and all that jazz. You know, inverse document frequencies, collection distribution, all that stuff. In the end, video objects returned in a search are given a ranking of 1 to 4 based on how well they match your query. It's not terribly advanced, and could use some tuning, but it's surprising how well it works. * XML-based. The search engine itself runs as it's own daemon on either it's own server or along side the web site, and just waits for connections via a UNIX domain socket or a TCP socket. When it receives a query, and sends back an XML document containing the search results. This is especially nice -- you can use it with anything for any purpose, not just a web site, i.e. you can build an native app for Windows and you can still use the search engine, and just format the results via an XSL or whatever. There are a lot of other nifty features, like being able to do remote admin via telnet or whatever. But in the end, it's still just a decent search engine and definitely not Google or even htdig. It's very focused on our specific task, the searching of online educational videos, so something using something like htdig would have required a lot of hacking to get it to where we wanted it. So the morale I guess is, sure, you can make a half-decent search engine out of PHP. Ours gets the job done. But remember, I only had, like, a scant few months to write one, plus a web-based app to go around it, and I was alone on this one. PHP was great for RAD, and the damn thing even works to boot. My search engine could handle a web site easily enough, maybe even a group of sites, but it would totally suck ass as a WWW indexer/spider-type search engine. So there ya go.

finding executables like php are a snap.
As for emailing from php/cron, it depends on how your system is set up.
Many email servers bounce any emails they receive from IPs that they can't
reverse map or otherwise identify. If your machine is on a LAN for
instance, the emails will probably get bounced.
Another thing to check is that your user account can actually use your
system's SMTP service. Email sent with php's mail() function are usually
sent by the owner of the script (or the web server's user).

So, now the question is, how can I send mail with php /

[PHP] Re: Using a HTML button
PHP is a server-side language (i.e. Perl when used with mod_perl), not a
client-side language (i.e. JavaScript). All of the processing is done on
the server BEFORE it is sent to the user. Therefore, you can't call a PHP
function directly from a web page after the user has received it, since all
of the processing has already been done.

The button has an OnClick, which calls my function.
INPUT TYPE=BUTTON name=HH value=Mul onClick=? $XX=multiply(5);?
I then writes $X to the screen.
?php echo $X ?
The problem is I dont even have to press the button. When the page loads
it already has calculated 2*$X. Why is that. I would like to only call my

[PHP] Re: PHP and security (like fopen)
It sounds like you're on a UNIX-like system. Ever hear of user/group file permissions? Just set the proper permissions on your directories and files and you're fine. There are many ways to do this sort of thing, so I won't get into it, but it would be much easier to focus on permissions than hacking the PHP source code for something so simple. Hint: A good place to start would be to look at the user that Apache runs as (or whatever web server you're using).

[PHP] Re: Running php in background?
For this sort of thing, it may be easier to run the job from a shell. Try compiling php as the CGI/CLI executable. Then you can run your scripts like, say, a Perl script or whatever. Just add the ampersand at the end of the command to run it in the background. (I'm assuming a UNIX-like system with some sort of sh/bash-like shell.) Also remember to set the timeout to 0 at the beginning of the script using set_time_limit(0); You might also want to surpress output to stdout for background jobs, which is generally preferable for UNIX background processes. If you still want to do it via the browser, just use set_time_limit(0). Even if you hit stop or the connection is broken, I think the script will still execute, unless you've registered a shutdown function, but I'm not 100% positive on that one.

[PHP] Re: PHP 4.1.0 patch for Quanta IDE, The Sequel
I sumbitted a similar patch to the Quanta team about a week ago. It may appear in an upcoming release, possibly Quanta 3, which will come with KDE 3.0. A few other additions I made: - highlighting is now case-insensitive for everything. I believe older versions were case-sensitive for keywords, like function, class, etc. - support for ASP-style opening and closing tags (% and % instead of ?php, ?, etc.) I'm also working on porting a newer editor from Kate/ktexteditor into Quanta. It's been slow going, but things have picked up (it compiles and runs now, albeit with a bunch of segfaults). This will make adding syntax highlighting instructions much easier, as the latest versions of Kate allow you to define highlighting rules in XML files, and the highlighting instructions are set up at run-time rather than compile time. Maybe over the XMas break I'll be able to finish it up.

Re: [PHP] ereg help
Something like this will work:
eregi(^id \{([a-z]*),([a-z]+),([a-z]+)\} \[(.+)\]$, $str, $regs);
$regs will be an array containing:
[0] = id {name,title,nick} [http://www.php.net];
[1] = name
[2] = title
[3] = nick
[4] = http://www.php.net;
If course this isn't very foolproof or generic. For instance, this regex
assumes that you have exactly three comma-delimited substrings between
those curly braces and anything goes in the brackets. (It could be a URL,
but it could also be anything else.)
This is assuming there are three items between those curly braces, however.
To handle multiple configurations within the curly braces, you'd probably,
as the boundaries would cause items in the array to be overwritten during
matching. Something like this may work half-decent...
if (eregi((id) \{(.*)\} \[(.*)\]$, $str, $regs))
{
$p[0] = $regs[1];
$p[1] = explode(,, $regs[2]);
$p[2] = $regs[3];
}
$p should now look like the following:
[0] = id
[1][0] = name
[1][1] = title
[1][2] = nick )
[2] = http://www.php.net;
That should do it. Of course, the regex again isn't foolproof, as you could
have crazy stuff for a URL, and it doesn't bother to check if there's
anything after a comma in the curly braces, but will handle any number of
items between the braces, and it's enough to get you started.

[PHP] Re: The future of PHP
XML is pretty standardized, but the implementation of it in various web browsers isn't. I wouldn't consider XML all that comparable to HTML. They don't serve the same purpose. XML is generally used to order and describe data (metadata, basically), and although HTML serves roughly the same purpose, HTML is much more focused in what it provides -- HTML is meant to be rendered in a web browser, while XML's use is really undefined. You can use XML for server-to-server communications, peer-to-peer stuff, messaging, document descriptions, and pretty much any generalized markup. HTML really isn't designed for that sort of stuff. As for freestyle, XML's syntax is much less open to interpretation than HTML's. XML is much more rigid -- forget a closing tag and your document becomes invalid. Screw up the order of your elements and it's invalid. If you forget a closing tag in HTML, you can be forgiven, but in XML, you're toast. Even linebreak elements in XML need closing tags. It doesn't really matter how IE and Netscape or any other browser renders XML. That's what XSL is for -- transforming XML into HTML before it is sent to the client. (Alternatively, the XML could be sent directly to the client and then doing the transformation client-side. As for XML scripting engines, again, XML is just markup, it isn't really a scripting engine. There is a bit of scripting-like looping structures and logic that can be used in XSL, but it's nowhere near the level of PHP, ASP, Perl, etc. Apache's Cocoon XML/XSL system does have a programming system built in called XSP (eXtensible Server Pages), which is basically takes Java embedded into XML or XSL and compiles it all as one big Java class. (You can add different languages to XSP, but it isn't fun. The next version will have producers that can create XML from scripting/compiled languages, including PHP.) I've mixed PHP and XML (with XSLT) on my current project quite nicely. I started with Cocoon and XSP, but as Sablotron and PHP's XSLT extensions became more stable, I started using them rather than combining both Cocoon and PHP. J Elias Santiago wrote: He MAY be right, may not. XML is just not so standardized (if in doubt look how IE and Netscape each implement it their way) I consider XML like freestyle HTML. I know this technology has great potential but if developers don't decide on how to standardize it, it could die young. PHP however (as an avid follower) is on a fast track and even Microsoft considers it a strong contender to ASP. However, both PHP and XML technologies are just scripting engines. Products like the Zend engine are just starting to scratch the surface for truly dynamic, cached, real-time web applications. I'm not saying that either PHP or XML (or any other technology that comes along) is going to die or leave the other in the dust but look what has happened with Java, it has certainly lost momentum. -- 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]
