RE: [PHP] Eregi error
Not sure, but I don't think you should escape all those characters inside of
the character class. I might be wrong. However, that might not have anything
to do with the error. But I do think you need to escape the / in the end...
And the - you should have in the beginning of the character class, otherwise
it will be treated as a range.

Subject: [PHP] Eregi error
Hey all,
I have been having some trouble with the "eregi" function. I have the
following piece of code in my application:
function standard_input($input, $min=0, $max=50){
if (strlen($input) <= $max and strlen($input) >= $min ) {
$pattern = '^[a-z0-9\!\_ \.- ,/]*$';
if(!eregi($pattern, $input)){
return false;
}else{
return true;
}
}else{
return false;
}
}
And i am running PHP version 5.2.1
I receive the following error:
*Warning*: eregi() [function.eregi
]:
REG_ERANGE in *[File Location]* on line *287
*Any ideas what might cause this? Googling REG_ERANGE only showed more
questions.

In a simple setup, that is probably true. However, if you use PHP to do authentication or throttling, then the engine is already there. On the flip side, you can use sendfile() or on Lighhttpd you can push the sending of the file back to the webserver using x-sendfile. > >> Image files do not need to be constrained by the rigid requirements of a > >> relational database. File systems are not immune to constraints. For example, ext3 only allows 32000 subdirectories. So if you gave each user a directory to upload files to, you would be stuck at a max of 32000 users. Or start going to silly things like /S/t/e/Steve.gif More constaints below.. > > What about when you need to share those files across a 50 node network? Webfarm scenarios do come to mind. There is an issue of how to sync all webservers to have all files. Then again, if you are using 50 webservers, the chances of them all being able to house all your files (1 petabyte, as an example given) is not very good. some databases support raw access in which case they're performance is probably just as good as the OS (and quite probably better if you want to store meta information about the file and it's data). While the database method makes for a good way of doing offsite backups (replicating out to a slave), the database can easily become a choke point as well. > > I'd keep it in a database, then when I need it cache a local copy on the > > filesystem.

You will need to keep information about what you are caching so that you can prune. Best choice I guess would be to keep a local sqlite db on the webserver to keep track. However, you had better understand your filesystem. In ext3, for example, if you have a lot of files in a folder you will likely use the dir_index option when creating the partition. But realize that deleting files does not delete leaf nodes of the btree, which can have all sorts of performance and disk usage effects that are non-obvious. There are hybid models, of course. mogilefs for example uses mysql to store data file info, but not the file itself. Instead a series of programs are used to spread the files across a farm of servers, using mutiple replicas for fault tolerance and performance reasons. Those files are stored using a combination of directory mazes and hashes to avoid typical filesystem issues. So there are lots of ways to deal with the issue. Depends on your constraints on time, complexity, and scalability. After all, if you only have 10,000 users, who cares! 100 million might be different. -s -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'd argue that's only true if you need to modify the contents, and you can't do so without a copy on the filesystem. Otherwise I'd have to disagree. Databases implement their own filesystem for the most parts. In fact many newer bleeding edge filesystems are practically database implementations. As such, the OS and the Database are merely layers over the raw medium. Sure the database is often layered over the OS's implementation of the filesystem, but that is not necessaril true since some databases support raw access in which case they're performance is probably just as good as the OS (and quite probably better if you want to store meta information about the file and it's data). > If you give me more information, I can counter with more specifics.

I'm quite comfortable with many tools.

Well one thing I know the webserver itself and the filesystem can't do is check the credentials of a logged in user to see if they are allowed the file. Well, I guess the webserver could do it... sort of... with http auth. Wonder if that works with many custom authentication systems... I presume you would somehow cram that into the webserver? I guess if the only tool with which you're comfortable is a screwdriver, then every job is more or less exactly like a screw. As such, I think you're screwed.

Unless you're the CIA doing pixel comparisons actually in SQL stored procedures or something. :-) Richard: I highly respect your opinion and on this list you provide tremendous help -- however -- I must disagree with you about storing images in dB's. Both techniques (using dB or the file system) have their up-sides and down-sides and neither have anything to do about CIA pixel comparisons? This idea of CIA pixel comparisons has been brought up before and it's pointless. There is no way for anyone to do a pixel search in MySQL. Images are not text and thus can't be subject to a "full text" like search. There are no functions in MySQL that will permit pixel searches AND that isn't important anyway -- not everything stored in a dB has to be search-able. That's not a requirement for entry! When someone uses a dB for storing images, that's what they are doing -- storing. I never store images without other data, like image type, size, description and such. So, why would I want to separate out that single attribute from a record and store that in a remote file system when I could just as easily store it in a dB? It's like saying "Never use css to display an image, only use html" when both work well under different needs. Furthermore, I have yet to talk with a single MySQL expert nor read a single MySQL book that claims what you claim. Could you be mistaken? Perhaps you might rethink your position. You know, we all learn -- I do everyday. Like Rob said in a different thread, it depends on what you're doing. If you're pulling out the image every single time from the db - that's bad - because your browser will never be able to cache it and you're putting more strain on the server because it will have to fetch the image from the database every single page request. If you're storing it in the db and creating a local cache copy which can be expired (through cron or some other means), that's good. You're reducing server load by having the local copy and have the advantage of replication in the database to distribute the image around. -- Postgresql & php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It has almost nothing to do with benchmarks. Images are typically best supported in the form of files. They are more easily manipulated by external tools. The web browser sees an image as a single HTTP request. Invoking the PHP script engine, parsing the script, and executing a SQL query to retrieve the image from the database is less efficient than letting the web server just send the file.

You could set up mini MySQL servers on the local client, or you could just use a text file, or perhaps SQLLite. You could even simplify things quite a bit by having the main application ALWAYS just write to the local storage. A cron job or second thread/task/process would be run to always be pushing the stored data up to the server. And then some kind of heartbeat to make it go "beep" when it's off-line for more than X seconds. This would be more resilient to temporary outages, and get the tricky sync stuff, as well as the network connection testing, out of the main application. I'm betting somebody has already done this kind of thing with PHP, actually. Sorry. -- Some people have a "gift" link here. Know what I want?

I already posted an issue with the standard socket and nobody volunteered any help, so I switched to IPC sockets)... aren't sockets supposed to be two-way communication? > -Original Message- > From: Richard Lynch [mailto:[EMAIL PROTECTED] > Sent: Wednesday, February 28, 2007 4:11 PM > To: Bob Dusek > Cc: Robert Cummings; Jay Blanchard; php-general@lists.php.net > Subject: RE: [PHP] operational musings > > Perhaps try just opening TWO old-school sockets, one for write, one > for read... > > On Tue, February 27, 2007 8:12 pm, Bob Dusek wrote: > > The company I work for is currently doing this... using PHP in a > > retail > > environment, with a Linux server in every store, talking to the POS > > controller via a socket, storing data in a database (postgres), and > > processing retail transactions in real-time.

I'm no expert, but as far as I can tell from my readings on this subject, the reality is that spammers just don't bother to harvest them. Ongoing studies, older studies, newer studies.

Not exactly, but the idea is along those lines.
What is happening is that $dom (DOMElement in this case) now points to
the same libxml2 structure as does $xml (SimpleXMLElement).
So now when you modify the structure of the document with one, it is
reflected by the other because they are in the same document. This also
means that it is possible that objects can become invalid by changes
made in the other extension.
$sxe = new
SimpleXMLElement("text");
$sxechild = $sxe->child->inner[0];
$dom = dom_import_simplexml($sxe);
$dom->removeChild($dom->firstChild);
var_dump($sxechild);
PHP Warning: var_dump(): Node no longer exists in
/home/rrichards/temp.php on line 8
object(SimpleXMLElement)#3 (0) {
}
This shows that $sxechild is still an SimpleXMLElement, but warnings are
issues that the node it refers to in the document no longer exists.
Although I doubt someone use the code above, it is the smallest piece of
code I could write to demonstrate the possibility.

Unless the libxml2 parser in SimpleXML can take advantage of the option, an XInclude method is not going to be added to SimpleXML. For things like that, and full XPath support, etc.., you need to interop with DOM so SimpleXML can be kept simple.

You could "obfuscate" the address with html encoding, such as: @ -> @ in the HTML @ -> %40 in the URL I believe the scrapers/spammers are still not bothering to defeat this trivial exercise because they still get a million hits looking for plain old emails. > In short, I can't see far enough how to do this and avoid > spider-raking > in the HTML or header the content of the image. I would suspect that every email is tied to some database record, like an ID. Provide a FORM which has only the ID in it, and lookup the email, and send the email out yourself from your own server. Yes, you could end up sending a LOT of email. Or not, since you now control the sending with PHP and can refuse to send in whatever scenario you find unacceptable. For example, one of my sites does this but won't send more than 4 emails from any given IP address in one 24-hour period. So a scraper/spammer would need to alter their IP every 4 POST operations, which is really more work than they'll put into it. On a super busy server with millions of users or millions of potential recipients, this would probably be a big deal... On MOST websites, you'll essentially be playing postman for a couple legit emails a day, at most, and not having any problem with scrapers/spammers. -- Some people have a "gift" link here.

Probably not exactly like that. One of the goodies is file length (actually, I think it's sample count, but same smell).

Just echo out each variable in turn until you are sure it's what you
think it is.
Somewhere along the way, one of them isn't.

[PHP] SimpleXML & libxml options (XInclude)
Hi there. I'm hoping someone can help me with what I think might be a slightly obscure problem. I'm trying to get the SimpleXML extension to read an XML file and process the XInclude statements within the XML file. The SimpleXML docs state that libxml options may be specified using the predefined constants that are available when PHP is compiled with libxml support (as it is when you use SimpleXML). http://uk2.php.net/manual/en/function.simplexml-element-construct.php So, looking at the libxml options, I see there is a predefined constant LIBXML_XINCLUDE which when specified should implement XInclude substitution. So my SimpleXML object I define as follows: $xml_file = './master.xml'; $xml = new SimpleXMLElement($xml_file, LIBXML_XINCLUDE, true); print_r($xml); Viewing the resulting datastructure shows me that it has not honoured the request to implement the XInclude directives. Does anyone know if a) I'm using the correct syntax for this, and b) have any experience of getting this working. My master.xml file looks like this: http://www.w3.org/2001/XInclude";> ssd sss xinclude - a.xml not found and then I have a.xml which looks like: test test more I'm running PHP 5.1.5 with libxml 2.6.20 on Fedora Core 4 linux.

You could export your data out of your DB, convert them to Unicode (normally in UTF-8), then import them into the DB. This might, at first glance, be overkilling and useless. But in long term, you'll be rid of a lot of problems due to encoding conversions and support to old encodings. And there's an even stronger argument for you in case the previous one can't convince you. Big-5 only supports traditional Chinese characters. As Macao is a part of China, and people tend to use simplified Chinese more and more, you'll sooner or later confront the problem of not being able to support simplified Chinese. Unicode, on the other hand, supports traditional as well as simplified Chinese (and a lot a lot other languages, but you're not concerned in this matter).

No need for a hex editor... 1) Take all your .wav files and use sox on command line (or another tool if you prefer) to convert them all to RAW PCM files (e.g. no header). 2) Take the filesize of the WAV and subtract the filesize of the RAW PCM. The value you have left is the size of the WAV header, so take the first n bytes of one of your WAVs and save it to e.g. "wav.hdr". Double check with your hex editor as I'm not 100% sure about this (OK, you do need it after all :p) 3) In theory to create the full wav you just concatenate the wav.hdr + the correct combination of your letters/numbers RAW PCM files. 4) You should be left with a proper, valid .wav file (I think). Not really sure of the above but I think it's all true!! Take care. Col. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'd suggest just using one table, and when you display the short version
just display a certain number of characters from the full version say 50
first chars as a preview this is what i use:
function debut_texte($texte, $nb_cars) {
$nb_cars = intval($nb_cars);
if (!$nb_cars || !$texte) return($texte);
if (strlen ($texte) <= $nb_cars) return($texte);
$nouveau_texte = substr($texte, 0, $nb_cars-3);
$nouveau_texte .= '...';
return ($nouveau_texte);
}
Sorry its in french, essentialy you pass it your text ($texte) and the
number of characters ($nb_cars) of that text you want to and it returns the
$nb_cars first characters and appends "..." to the end of the text.. This
will save you some confusion by using two tables for the same data...

Unless you're the CIA doing pixel comparisons actually in SQL stored procedures or something. :-) Richard: I highly respect your opinion and on this list you provide tremendous help -- however -- I must disagree with you about storing images in dB's. Both techniques (using dB or the file system) have their up-sides and down-sides and neither have anything to do about CIA pixel comparisons? This idea of CIA pixel comparisons has been brought up before and it's pointless. There is no way for anyone to do a pixel search in MySQL. Images are not text and thus can't be subject to a "full text" like search. There are no functions in MySQL that will permit pixel searches AND that isn't important anyway -- not everything stored in a dB has to be search-able. That's not a requirement for entry! When someone uses a dB for storing images, that's what they are doing -- storing. I never store images without other data, like image type, size, description and such. So, why would I want to separate out that single attribute from a record and store that in a remote file system when I could just as easily store it in a dB? It's like saying "Never use css to display an image, only use html" when both work well under different needs. Furthermore, I have yet to talk with a single MySQL expert nor read a single MySQL book that claims what you claim. Could you be mistaken? Perhaps you might rethink your position.

[PHP] FTP issues
The following issues are not really PHP issues, but more properly FTP server issues, but perhaps people on the list have some ideas on how to solve my problems. I've written a PHP program to "mirror" data on a local drive to a remote FTP server. It compares file mod times, and only uploads files that are newer. Works like a charm. Except --- The remote FTP server is running on a Fedora LINUX system, but I think any server would present the same issues. To examine the remote directories, I use ftp_rawlist() to get a directory listing which I parse. However, the file modification time does not have a year, and does not show the seconds. I get around this by "assuming" the year is the current one, and then compare the file times of the local and remote files ignoring local file seconds. If they are different, I use ftp_mdtm() to get the real remote time, and then do my compare. This slows things down a bit, as I have to go to the FTP server one more time. Any thoughts on how to get around this? Is there a way to get a better directory listing? Second and more serious problem is that when I FTP the file to the server, the file mod time gets set to the current (file-creation) time. The same thing happens in a local-to-local file copy using copy(), but I can use touch() to update the mod time. Any thoughts on how I might get the remote FTP server to do the equivalent of touch()? I realize that these are not actual PHP problems, but maybe one of you has run across similar issues. Many thanks.

you can change the include_path definition in your script. you can also include
files which live in other directories than those defined in the include_path
ini setting.
I doubt you are allowed to upload any files to /include or /usr/lib/php, so your
recourse is to create your 'include' directory somewhere where you can upload
stuff
to and then optionally redefine include_path to point to your personal
'include' dir,
something like:
ini_set('include_path',
ini_get('include_path').':/path/to/your/personal/inc/dir');

there is possibly another way by using the Rewrite engine to explicitly
set ENV variables based on apache interal, something like this:
RewriteEngine On
RewriteRule ^.*$- [C,E=VHOSTS_ROOT:/var/www/vhosts]
the above rule ends up providing $_SERVER['VHOSTS_ROOT'] in your script,
a little contrived but you can also do stuff like:
RewriteRule ^.*$- [C,E=THING:%{REMOTE_USER}]
the 'C' make the rule chained so that you can include it alongside existing
rules transparently.

in the past I found the following to be annoying enough for harvesters not to
bother:
function obsfucateString($str)

I think that changed from version to version, so unless you are on a dedicated server, you have to manage any order dependencies for yourself... I do not think there *IS* a documented ordering to this. Actually, I think it is documented that the order of the destructors cannot be predicted. This means that even if you find how it is done in this particular version, don't count on that to hold if in a newer version they change it. By stating that it cannot be predicted, the developers reserve the right to change it at any time. When an object is deleted, it is put in the list of things to be dispossed of, and the garbage collector will call the destructors prior to deallocating the memory. It can happen at any time when there is no higher priority stuff to be done. So, it all depends on the whim of the garbage collector, a background item that the developers might change at any time and whose behaviour depends on lots of unpredictable things such as server load.

ehh, what is the problem? you didn't tell.
I guess that the fullnews page don't display the news correctly, right?
if so, please show us the code of that page
btw, why are you using two tables?
everything could be put in one with fields like title,shorttext,fulltext
and so on...
and then there would be only one id for one article, which could reduce
confusion and eliminate some possible problems
hope that helps

[PHP] ID problem
Hi,
I'm building an CMS system (for practice and experience :)).
And of course like many times before I have encountered a problem.
The problem is:
I have a index.php that takes the news from the database and publishes
them. And by the end of every news on index.php I have a link ('href="showfullnews.php?id=$id">Show full news')
That leads to a page that has the full news.
At the beginning of showfullnews i have a variable ( $id = $_GET['id']; )
And in index.php I have the following code:
while ($row = mysql_fetch_array($result))
{
$id= $row['id'];
etc...
}
In the database I have two tables one for a short version of news for
index.php and another for fullNews.
In full news the query is: "select title,newsFull from fullnews where
id='$id'";
In the database i'm 100% sure there is a id = 1 in both rows.
I really dont know what is the problem.
Thank you very much!

Re: [PHP] IE6 session issues
OK. Blank entries means that as date is passed in and validated via forms, it is then entered into $_SESSION so data can be persistent as the user goes back and forth. These values are eventually entered into the database and are blank, whereas the few values that are entered from $_POST (ie credit card numbers that I don't want to carry around in the session) are fine. The system works in IE7, FF and Opera and has also worked on my local version of IE6. I have created a session name and send the Cache-control:private header, which fixed similar issues in the past, but no success in this case. -- http://www.web-buddha.co.uk
