Re: [PHP] Sessions running out of storage space - Increase memory?
Dan wrote: After thinking about this a while I also thought of making my own cache. The problem with that is would it be any faster or have any less strain on the server than having multiple requests/connections to the database? A lot depends on the amount of data and the overall load on the web-server. If you do the query once, then store the result in a file, and then keep reading that file for the next cachetime seconds, the file will most probably remain in memory, so accessing it will be fast and without IO. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Greetings,
I am attempting to alternate the colors of the container DIV. Anyone know
how to do this?
Hi Steve:
Easy and simple.
First, keep presentation separate from data. In other words, use css
to define a css-class, like so:
.row0
{
background-color: yellow;
}
.row1
{
background-color: #809FFF;
}
Second, embed php into your table, like so:
tr class=row?php echo($i++ 1 );?
You can see a working demo here:

[PHP] session_start is slow occasionally
Hi i have a site that is relatively high loaded (~20 reloads/sec) and i am
trying to optimize it.
So i have started timing sections of the php scripts to find out which is the
slowest so i optimize it first. I write the times to a database( timings are
done on the live server). So now when a user reloads the page (timings are set
on only one of the pages) i write to the database how long it took and how long
different sections take. That way i noticed thar occasionally that page takes
extremely long to generate (there are occasions of 300sec), but generally it
takes between 0.05 and 0.2 sec to generate. I started moving the sections to
determine where the problem lies and it turned out that these three lines take
that long from time to time:
ini_set(session.gc_maxlifetime, 2400);
session_name('x');
session_start();
I measured each of them and seems that session_start is the problem(had a few
~11 sec loads, but not something this big yet, of which ~10.5 is taking
session_start)
Does anyone know what is going on? Sessions are stored in /tmp/sessions/ which
is 100MB ram drive and at the moment when this occurs it was ~68% used with
~12000 files in it.
And i have one more question. How does apache handle high loads? Does it
suspend the php script when there are no resources and resume it when it frees
some, or it doesn't pick it up at all?
Thank you

[PHP] Generating PDF files (XSLT, ps, XSL-FO, FOP, etc)
Hello, I'm currently researching a bit on a possible PDF export format for some of my application's output. So far, what I get is this: - some packages allow PDF generation (FPDF, EZPDF, etc) from nothing - some packages allow generation of PDF from HTML, using the ps format - some packages allow generation of PDF from XML, using XSL-FO and FOP Somehow, I'm having difficulties understanding why you can make a PDF out of nothing (using only a set of PHP classes) but you can't generate a PDF using XML and XSLT, although XSLT is, to my understanding, made to enable export in various formats from the same XML file. It seems that in this case (exporting from XML to PDF), you need to first convert the XML to a XSL-FO format (using XSLT) and then convert that XSL-FO format into PDF, and the only way to do that last step at the moment seems to be to use Apache's FOP project, which requires Java and a server-side component that you are unlikely to be authorized to install on a low-cost hosting server. Does anybody have a good insight on all this and could tell me what's wrong and why there seems to be a missing link between XML and PDF...?

RE: [PHP] Alternate Colors in Rows
My comment was not about the CSS -- if you saw my earlier post, I actually
told the OP to never hardcode color/style if possible:
-Original Message-
Sent: Wednesday, October 03, 2007 12:58 PM
Add this to your default.css file... Or to the page...
style
TR.dataRow1 { background-color: #e8f5f7; } /* light */
TR.dataRow2 { background-color: #dce8ea; } /* dark */
/style
Then just do this:
TR class='?= ($r = !$r) ? dataRow1 : dataRow2 ?'
Forget all that $i++ and (mod) % stuff...
And NEVER hardcode the colors in the page. Use CSS !
What I was shocked at was the use of a class to do what takes not even an
entire line of code to accomplish. You realize that the object-oriented-ness
(word?) and the overhead of a class is silly right? Even calling a function
is slow. Something like alternating table rows generally is used when you
have lots of tabular data to show, therefore shaving off a few microseconds
here and there actually adds up. We have pages that render thousands of
rows, and if it takes 2 or 3 seconds less to show, that is significant and
noticeable.
I'm sure you were just trying to be funny or illustrate a point, but what
concerns me is that some people take OO WAY too far -- Ruby is an example.
Sometimes it is NOT the best way to implement something and is actually
detrimental. Since the OP seemed sorta newb, I fear that he would be
learning bad habits and not get that you were being facetious about the
PHP example...
Anyways, this is a dead horse.

[PHP] Reading files from Win 2003 Server
Hi, I have a script located on an Ubuntu box and I am trying to read files located on a Win 2003 Server. I have 'mounted', if that's the right term to use, a connection from Ubuntu to Server 2003 and can read the files fine via the desktop, etc. If the Win Server name is say 'WinServer' and the shared directory I want to read from on it is called say 'SharedDirectory' and the user name is 'User', I notice the reference to that folder on the Ubuntu desktop is as follows: smb://[EMAIL PROTECTED]/SharedDirectory But I am at a loss as to how I should refer to the path for this connection within my PHP script. Any help would be most appreciated. If it's any additional help, I would be using the connection to read files only, and not add/edit/delete them.

Re: [PHP] session_start is slow occasionally
al jo wrote:
Hi i have a site that is relatively high loaded (~20 reloads/sec) and i am
trying to optimize it.
So i have started timing sections of the php scripts to find out which is the
slowest so i optimize it first. I write the times to a database( timings are done
on the live server). So now when a user reloads the page (timings are set on only
one of the pages) i write to the database how long it took and how long different
sections take. That way i noticed thar occasionally that page takes extremely long
to generate (there are occasions of 300sec), but generally it takes between
0.05 and 0.2 sec to generate. I started moving the sections to determine where the
problem lies and it turned out that these three lines take that long from time to
time:
ini_set(session.gc_maxlifetime, 2400);
session_name('x');
session_start();
I measured each of them and seems that session_start is the problem(had a few
~11 sec loads, but not something this big yet, of which ~10.5 is taking
session_start)
Does anyone know what is going on? Sessions are stored in /tmp/sessions/ which
is 100MB ram drive and at the moment when this occurs it was ~68% used with
~12000 files in it.
My suggestion is check the php source for what session_start does. Maybe
it scans the directory to make sure it's going to generate a unique id
and even though it's on a ram drive it's taking a while because of the
number of files already there.
That's just a completely wild guess though ;)

the question is when is the variable you want to append available to the
javascript.
as soon as you get the variable in the javascript the next thing you can do
is append
it to the value of the href attribute of the a tag.
html
head
script type=text/javascript
window.onload = function() {
var someLinkHref = document.getElementById('someLink').href;
someLinkHref += anotherVar=8;
alert(someLinkHref);
}
/script
/head
body
a id=someLink href=http://somesite.com?a=5;
click here
/a
/body
/html
if you want to use the onclick event handler as rob suggested, you could
stash the variable in the Window
global object, then reference it in the implementation of the onclick
function (though i still have mixed feelings
about that approach [the Window object part that is]).
