correct. local file caching, APC, etc... but that doesn't really help,
since you'd be constantly throwing out data (acting as an LRU) and
have one copy of the data on each server is wasteful...
yes the thing that makes memcached the best is the distribution. it
also makes it not a requirement for cache persistency (if there is
such a concept...) not -just- sessions. session persistency to me is a
concept from the 90's...
memcached's distribution in action (20 servers) for example:
20 megs of data x 20 servers = 400 megs of data used total (local cache)
20 megs of data x memcache = 20 megs of data. 40 if you copied it
twice (using pecl memcache) to alleviate cache stampedes.

Ah, but each server will only have what it needs for its clients. So if
you've got say 2000 clients spread over 10 servers, each server will
have the data relevant for its 200 clients. And there is no need for
network access everytime you reach for a cached object. (only if you
don't find it in cache).

Yeah, you mentioned that before. The computer is a concept from the
early 1940s - but it's still holding up :-)

eh. seems like the way of the future is distributed, not silo'ed.
computer components will fail (come on, hard drive specs are measured
by how often it fails, how's that for a metric)
in your situation, all the clients from B would migrate to A and C,
and all the data would be re-cached again... i don't know, on paper it
probably consumes more memory. i guess we'll just disagree here, i
like shared nothing style distribution, and something about keeping
servers as islands conflicts with that to me.
from what everyone seems to find is that memcached's additional
network access is pretty much trivial.

Hi, after enabling error reporting with E_ALL I am having this strange
warning while loading a XML:
Warning: DOMDocument::load() [function.DOMDocument-load]: Extra content
at the end of the document in [...]
The code I use is:
$dom = new DOMDocument();
$dom->load("http://example.com/file.xml";);
[...]
If I open the xml uri (with firefox) I get a complete and well formed
xml (nothing strange about it).
With error reporting disabled everything works fine so I am
puzzled :-( Any help will be appreciated.

check raw the file output by doing:
print_r(file_get_contents("http://example.com/file.xml";));
that should show you exactly what's causing the error.
another possibility is that the site has bot protection on there and is
redirecting your request to a standard web page.
Alternatively pass the url to the XML file to me and I'll investigate
for you.

Is there an extra whitespace or carriage return/newline after the
final closing tag?

I don't think extra whitespace will do that. Even comments after the
closing element tag should be OK. This looks more like a document with
multiple "root" elements or other non-whitespace characters after the
closing root element tag.

Hello,
I vote for Typo3 template system. If you work bunch of HTML only designers
this one best.
If you have some php avare designers, you should go with php based + memcached
template systems.
Second option was much faster anything else.
Just store the template into memcached and do some str_replace.

Sancar

About designers who don't know PHP.
There are two kinds
1). They draw only. They usualy don't know even HTML - they just draw.
2). They know HTML and make templates. usualy these people have to know HTML
and CSS very well. And I can't imagine how they can do that without knowing
at least Smarty tags (if they work with it). My idea is basicly that for
them there is no difference if there if
<?=$variable?>
or
{$variable}
They just have to know that such constructions displays some data.
So I and my colegaues stick to HTML with PHP injections in templates (i
worked with smarty once's, have to say comparing to PHP it was realy a mess.
And at least with PHP I have code highlight).

You won't find many solutions (if any) faster than require(). If all you
have currently is developers you don't really have reason to use a
custom templating language to slow things down. Even when you do get
designers, they should:
1. Not have the final say before systems go live
2. Not be brain dead enough not to understand this:
<?if($foo):?>
...
<?endif?>
Or for simple variable this:
<?=$name?>
3. If your front-end people can't understand that (and you can of course
expect training to be necessary or some sort of cheat sheet that can
be referred to), then they quite honestly aren't worth employing.
(the alternative syntax for PHP conditionals and loops, along with short
tags)
And there should of course be some sort of test site on the same box as
your live site allowing you to thoroughly test your new stuff before it
goes live.

^^^^^^^^
Mine is faster. Compiling to the requested page removes cache overhead
and file access overhead since the content is already pulled in.

Hello All
I have a situation where I have to copy something like 1000 files one
by one to a temporary folder. Tar it using the system tar command and
let the user download the tar file.
Now while the copy is going on at server, I want to show some progress
to the user at client side. Most of the tutorial I found on net was
about showing progress while a file is being uploaded from client to
server. In this case the client has the info but for my case, the
client has no info.
A similar was problem was solved at
http://menno.b10m.net/blog/blosxom/perl/cgi-upload-hook.html but its
in PERL and uses some form of hook. I have no clue how to do it in
PHP.
Any clues or right direction would be awesome.

Write a bash script on the fly to do the work, execute it using php,
output the progress of the bash script back to the browser using output
buffering.. just remember to pad the strings to buffer size and flush()
so they actually get sent.

For sending email:
The standard mail function
http://php.net/mail
I've found that for sending anything more than the simplest email,
it's usually easier to use something like PHPMailer (http://phpmailer.sf.net
).
For creating PDF files, here are a few options:
http://fpdf.org
http://www.ros.co.nz/pdf/
http://framework.zend.com/manual/en/zend.pdf.html
Saving the pdf and sending it as an email shouldn't be difficult:
Step 1 - Generate the PDF
Step 2 - Save it somewhere on the server
Step 3 - Email the PDF as an attachment.
I don't fully understand your question, so hopefully this is somewhat
helpful. If you have specific questions about parts of the process we
will be able to help you better. Best is if you start writing the code
and ask questions when you get stuck so we can see what's going on and
offer ideas.
Best of luck,
Brady

It might be overkill for your purposes, but you might want to explore
pdftex in Tex (or LaTeX), available for both Linux and Windows.
Create a string to write to a file, adding these header calls at the
top, massaged to your needs:
$outputStr = "\\documentclass[10pt,fleqn]{article}\n";
$outputStr .= "\\usepackage[cp850]{inputenc}\n";
$outputStr .= "\\usepackage{textcomp}\n";
$outputStr .= "\\setlength{\textwidth}{19.05cm}\n";
$outputStr .= "\\setlength{\oddsidemargin}{-2.0cm}\n";
$outputStr .= "\\setlength{\textheight}{26.5cm}\n";
$outputStr .= "\\setlength{\topmargin}{-1.9cm}\n";
$outputStr .= "\\setlength{\headheight}{0.0cm}\n";
$outputStr .= "\\setlength{\topskip}{0.0cm}\n";
$outputStr .= "\\begin{document}\n";
$outputStr .= "\\pagestyle{empty}\n";
$outputStr .= "\\begin{verbatim}\n";
$outputStr .= "Then append to the string whatever you want, including
variables for interpolation, formatted however you want. (Sprintf
works really well for alignment, etc...). The verbatim call above
leaves in place all text placement on the page.";
$outputStr .= "Then close the string with these commands...";
$outputStr .= "\\end{verbatim}\n";
$outputStr .= "\\end{document}\n";
Write to a file:
$fh = fopen("FileName.tex", "w");
fwrite($fh, $outputStr);
fclose($fh);
`pdflatex FileName.tex`; // ( properly escaped, of course...)
and FileName.pdf is created.
You can also do a lot of really fancy formatting, but the learning
curve can be pretty steep.

Hi,
I have a problem with fsockopen in connection with the UNIX abstract
namespace.
To open a UNIX socket in the abstract namespace I have to add a nul byte
in front of the path.
Unfortunately PHP returns
fsockopen() [function.fsockopen]: unable to connect to unix://:0
(Connection refused)
for unix://\x00/tmp/dbus-whatever which is a bit strange because I
expected at least the error message "fsockopen() [function.fsockopen]:
unable to connect to unix://[NUL byte]/tmp/dbus-whatever:0 (Connection
refused)"
Is this a known issue or do I have to set something in the php.ini?
I would appreciate any ideas how to debug this issue.

For RAD-style database design, check out OpenOffice.org Base. I
know it comes pre-packaged with Mandriva (which I use), but I'm not
certain about other distros. Depending on your flavor, you can
probably apt-get, yum, urpmi, or manually install from an RPM or DEB.
It works a lot like Filemaker and Access, so if you're familiar
with those, you should notice a lot of similarities. Plus, it will
work without a problem with MyODBC, Unix ODBC, JDBC, and native
connections.
For future reference though, Shawn, try sending to the PHP-DB list
when asking questions like that. Then it's not off-topic. ;-)

did you ever report a bug on this ?
i was messing around with it today, and i discovered that some urls,
partially work. for example the google translate 'api', and php.net
note, i set the user agent for the google site to work. and i say,
partially, because even when data does come back, its not the complete
page, which you can easily realize by navigating to the page and comparing
the source w/ the output from the test script.
i dont know of any ini setting that would influence the amount of space
available to the memory buffer, aside from memory_limit, which i have set
to 128M.
