[PHP] XML Parser misbehaves with &
I've come across this frustrating behavior with the XML parser when it reads an escaped ampersand (&) If the xml being evaluated is: Blue, Green & Red it calls the character data handler 3 times: the first time the $data is "Blue, Green " the second time is "&" and the third time is " Red" Needless to say this is screwing up my parser, and the stuff I'm doing won't make it easy to add this allowance. I'm hoping somebody can point out a way to turn off this behavior. If this is the proper operation, is it documented anywhere?

[PHP] Replacing Unicode characters
I'm working on an application where I need to replace some Unicode characters with a PHP shell script. The problem I'm having is matching multibyte characters. One character in particular is Unicode 2014 an m-dash '—' To get the decimal code to identify the character I've tried two methods, one was with a little script like this: I took the multiple decimal codes returned and tried a replacement like: echo str_replace(chr(226).chr(128).chr(148),"-hyphen",$data); But that didn't match it I figured my method of finding the decimal value wasn't correct. Next I thought if I UTF-8 encoded the character and took the ord() and used that decimal to compare against a utf-encoded version of my string. but when I tried getting the ord() of all the characters I wanted to watch for it always gave me the same decimal, 195. So that idea wasn't going to work either. I'm out of ideas, any input would be appriciated.

Re: [PHP] pages compressed with zlib
It will only send compressed pages to browsers that support it so that's not a problem. Pro's are that pages load much faster. especially if your HTML output is big, images are already compressed so they stay the same. cons are minor, since the page is gzipped when loading on a browser it doesn't "cascade" onto your screen, it appears all at once when the transfer is complete, so the total load time is faster, but it's a little longer before the user see's anything. I'd also guess that gzipping every page will make the processor work harder. but I've never had a problem with that. test it out, we noticed big differences on modems to our site.

[PHP] RPM apache+php v. source apache+php
This is a tough question to ask because I know there will be a fare
share of people who just want to flame Red Hat, but this just might
start a healthy discussion.
What is your opinion of using Red Hat's Apache and PHP binaries instead
of compiling from source? If Red hat is too specific for this list we
can expand it, but that is the binary that I'm interested in seeing how
it stacks up.
Red Hat compiles a bunch of stuff into both apache and php but most of
it is modular so it shouldn't have enormous amounts of overhead. On the
other hand, it sure is easy to keep up to date, and when you have a lot
of servers that is a big plus.
If you need a feature in php that is not included in the RH configure
you are better off using source, I've tried building the php source RPM
adding some new options and didn't come close to getting it to work, but
I'm not an expert in building RPM's and maybe it was all my fault.
If there was a performance difference you would assume that the source
install would have it, has anybody compared performance of the two and
is there any measurable difference?
For those of you that are of the mindset that everyone should compile
everything from source, that's duly noted, but I'd rather hear from
people who weigh out the benefits of using one or the other and go with
the best choice.
Thanks for you time.
Here is the configure from the Red Hat binary:
--prefix=%{_prefix} \
--with-config-file-path=%{_sysconfdir} \
--disable-debug \
--enable-pic \
--disable-rpath \
--enable-inline-optimization \
$* \
--with-bz2 \
--with-db3 \
--with-dom \
--with-exec-dir=%{_bindir} \
--with-gd \
--with-gdbm \

--with-mm \
--with-openssl \
--with-png \
--with-regex=system \
--with-ttf \
--with-zlib \
--with-layout=GNU \
--enable-debugger \

--enable-safe-mode \
--enable-sockets \
--enable-sysvsem \
--enable-sysvshm \

--enable-yp \
--enable-wddx \
--without-mysql \
--without-unixODBC \
--without-oracle \
--without-oci8 \
--with-xml \
--with-expat-dir=/usr
And it's split into the following packages:
php
devel
imap

pgsql

[PHP] header("Location:") problem with Netscape
I'm working on a app that uses the header("Location") is the middle of
the file, but since I'm using output buffering it shouldn't matter. The
application works fine in Mozilla, Konqueror, and IE, but not in
Netscape 4 or 6.
I don't get the error that the "headers have already been written"
error, it just loads the page as if the header("Location:") was
commented out.
Some of my thoughts on the subject. I'm redirecting to $PHP_SELF is
Netscape trying to be extra smart and think it doesn't have to refresh?
I'm using gzip compression in output buffering, maybe there is a
situation where Netscape 4 & 6 may not use the gzip compression, hence
causing the output buffering not to work correctly? But if that was the
case I should see the error about headers already been written.
Any suggestions would be great, thanks.

[PHP] using a mysql temporary table.
Hello, I'm trying to use a temporary table in mySQL with PHP. First I tried to create a temporary table and then query it in the same script. But the table didn't persist to the second query in the PHP script. I found this knowledge base entry: http://www.faqts.com/knowledge_base/view.phtml/aid/445 Where it shows to do all the querying in one swoop. The problem I'm having now is that PHP is throwing an error at the first semi-colon. It appears that it doesn't want to run multiple query statements in 1 query function. I'm using the mySQL pear class in my application, I wouldn't think that it would have any effect on the problem. Here is an example of the query I'm attempting. CREATE TEMPORARY TABLE tmp_events SELECT event_id, event_title FROM events; INSERT INTO tmp_events SELECT event_id, event_title FROM special_events; SELECT event_id, event_title FROM tmp_events ORDER BY event_title; But I get an error like: 1064: You have an error in your SQL syntax near '; INSERT INTO tmp_events' If I echo my SQL statement and paste it into mySQL the query works fine. Any suggestions that you can offer would be great. -- Jeff Bearer, RHCE Webmaster PittsburghLIVE.com 2002 EPpy Award, Best Online U.S. Newspaper -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] problem while loop.
Well, I found the problem. it wasn't happening where I thought it was.
which brings up another question I'll have to ask in a new subject about

Re: [PHP] problem while loop.
It's all returning proper dates and the proper timestamps when I check
them inside the loop. I'm formatting the dates in -MM-DD format and
strtotime is returning the proper timestamps. I'm curious how can you
say it's a problem with the dates when the if statement comparing the
same expression as the while loop works properly?

[PHP] problem while loop.
I have a problem while loop that isn't terminating when it's supposed
to. I can't figure out what the problem is, if I run a comparison
inside the while loop it matches as it should, but for some reason the
same comparison isn't working as the while loop expression. I get an
infinite loop when I run this code.
while(strtotime($event_date) <= strtotime($end_date)){
# test to see if the loop should of stopped.
if(strtotime($event_date) <= strtotime($end_date))
echo "GO!!\n";
else echo "STOP!!!\n";
/* omitted code that finds the next $event_date */

[PHP] Date Question: finding 1st Monday of sept.
Hello,
I'm trying to find out how to calculate some dates, and the part I'm
having problems with is finding the date of the first Monday in
September.
I'm looking into the strtotime() function which works some great magic
with dates, but I can't figure out how to use the day of the week syntax
start from a date other than today.
You can use releative dates with units of days:
strtotime("2002-09-01 +2 weeks");
But I can't seem to get it to work with the weekdays, I'd assume it
would be something like this.
strtotime("2002-09-01 first monday")
Is there a syntax that I'm missing or is there a way of fooling the
function to thinking it is September 1st so when I ask for next Monday
it will give me the correct date?

Re: [PHP] Caching in php?
There is Zend Cache, it expensive and you have to pay per processor. That drove folks to develop APC (Alternitive PHP Cache) which is open source. http://apc.communityconnect.com/ They take the PHP source and compile it into machine code and stores that code, which saves porcessor overhead when the page is loaded again. APC worked well for me, but that's not where my bottleneck is, mine is with database access so I wanted to cache database queries. I couldn't find any application that did what I wanted so I wrote a class that handles caching queries. In programming it I wanted it to be a transparent as possible and make using it just like using the PEAR mysql module so I could add it to my site with minor modifications. Here is a little on how it works. It checks to see if the query is cached, if not it queries the database. It takes the data returned from the query and stores it in a xml file, which I have on a RAM disk for speed. It returns a result object similiar to the result object from the PEAR mysql stuff. And that object has a FetchRow function just like the mysql result object so it drops right into existing code. It's new and I haven't truely tested it's proformance yet but if you are interested in it. Let me know, I'm positive that people will be able to improve the code in the class which would be cool.

Re: [PHP] How should I cache database data for php?
DN, Yes the db server and the webserver are on the same box, local connections are much faster than network ones according to mysql. When the site is busy the percent of the system being used by mysql and that being used by PHP/Apache, I estemate would be around 90%-10% so if I get the db load down I'll have smooth sailing. I'm not attempting to elimate the compalition of PHP, I just want to eliminate some database queries. I don't particually care for the idea if writing static html files. I've had really bad experiences with stale files our old system. The way I'm exploring now is to build a caching layer between the php application and mysql. I want the app to query the caching layer just about the same way it queries the database, but add a few other details, time to live, cache name etc. The caching layer will check to see if the query is cached, make sure it's not expired, and return the data just like a result set from the db query. If it is expired, or doesn't exist then it will query and create the cache file for next time. I'm leaning toward storing the data in XML, and kicking around the idea of storing it on a ram disk so it would have killer fast access time. I expected to get tons of links to libraries or other apps that have data caching, I'm quite supprised that I haven't yet.

Let your db do the > work, that's what it's for :) But at 300,000 page views a day, even if the caches only have a ttl of 1 hour I'm still saving over %90 of the traffic from having to query the database.

[PHP] How should I cache database data for php?
Hello, I have a PHP content management application that I've developed. I'm looking to add data caching to it so the database doesn't get pounded all day long, the content on the site changes slowly, once or twice a day. Does anyone know of where I can look to find an application that does this? I've searched and have yet to find anything that does the same kind of thing. I'll take anything, a module or library that does it, or even some other application that does the same thing that I can look at. Ideally I think it would be cool if it would be a PEAR module that the application connects to just like the database, and it manages chaches and querying the database for data in the module. -- Jeff Bearer, RHCE Webmaster PittsburghLIVE.com -- 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] Version Contol for PHP site
Hello, I'm trying to come up with a workable solution to implement version control for our site. I have developers that use windows, and don't know too much about the unix command line, so I'd prefer to use a windows client to work on the site if possible. I'm looking into CVS for the version control and I've found some directions on how to use it with websites. But it only talks about static HTML development, it doesn't say how developers would debug PHP, CGI, etc. This solution would not give them any ability to debug their code before checking it back in. I suppose if I could get them all comfortable with the UNIX command line, they could work on the development server, checking out the files to a working directory that is also a virtual host. A new idea that I just came up with would be to have the developers use VNC viewer to connect to an X server on the development box. The deveopers could use a X GUI for CVS to check it out, and edit files etc. and keep the working directory a virtual host like above. Is anybody doing something like this with their PHP development? Any direction from a working implementation would be great. And what do you think about the VNC idea that I just came up with? -- Jeff Bearer, RHCE Webmaster PittsburghLIVE.com -- 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]

I'm getting this error with my php installation, I first assumed that it was because I didn't have GD and friends installed.

[PHP] register_shutdown_function and a MySQL query keeping connection with browser.
I've been working with register_shutdown_function() to have the browser kick of a
long running script and move on to other tasks. I was having problems where the
browser
would sit and spin untill the function was done running, then would display the page.
I tinkered with flush and fflush (i'm writing to a file also) but that didn't work
either.
Flush showed me the screen, but the browser still keeps the connection open untill
the function was done running. It seems to be caused by the mysql query or result and
the
loop of the result set. Below is some of the test script I put together. I'm using
the
PEAR DB_mysql class. I'm using the sleep where the part of the real script takes some
time
to run.
Has anyone dealt with this before, does anyone have any ideas? The only idea I've
thougt of
so far is to load the record set into a 2D array and then flush the result set. That
might
allow the browser to disconnect before the time comsuming job starts.
Any suggestions will be appriciated.
connect($dsn);
echo "hello";
register_shutdown_function("tester");
exit;
function tester(){
global $db;
$sql="SELECT * FROM table";
$result = $db->query($sql);
while($row = $result->fetchRow(2)){
sleep(5);
}
}
?>

Re: [PHP] encryption
Ahh, well then, another solution could be to use SSL, depends on your application weather you can get away with using an unsigned certificate (free) or weather you will need to pay a company like verisign to prove your identity. With an unsigned certificate the browser will warn the user that the certificate says it's you, but it's not proven by a CA so it might not be you. The JavaScript MD5 tenique is an interesting way of doing it, but i don't think it's any more secure. If a hacker sniffs the md5 hash how is that any diffrent than him sniffing a plain text password? You're comparing hashes, so as long as he has the hash he's in.

Re: [PHP] Using GnuPG with PHP
For anybody who cares I found the problem with the command below, the environment of the webserver user was set to the environment of the user who started it, so it could not find the ~/.gnupg directory so I added the --homedir switch and all is fine. Thanks for the imput however I'll examine popen further.

Re: [PHP] encryption
I'd use the password function in mysql to store encrypted passwords, I'd be interested to hear if anyone has a reason that doing this is not a good idea.

[PHP] Using GnuPG with PHP
I saw examples of how to encrypt data with GnuPG in the list archives but I'm having problems that aren't mentioned. I've installed the public key in the web server users key ring, and if I run the command as the web server user it works just fine. But when the script runs it I get nothing returned and no errors. $command="echo \"$plain\"|gpg -e -a --always-trust --no-secmem-warning --batch -r public_key"; $encrypted=`$command`; I've tried with and without the --always-trust, --no-secmem-warning --batch in just about any order. If i try to write it to a file with -o the script does not create the file and there is still no error. I'm assuming that STDOUT is returned to $encrypted with the backtick operator, how to I see what STDERR of gpg command is? I figure there has to be something there. The only thing I can figure is that the environment for the web server is different than when you su to the web server user. and that's messing things up. Any help is appreciated, Thanks. -- Jeff Bearer, RHCE Webmaster PittsburghLIVE.com -- 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]
