No plans from us, no. Running a certification program is a lot of work
and I would prefer to see developers develop, not try to manage a
certification program.
As for the www.expertrating.com thing? Never heard of it. If a resume
crossed my desk with a reference to something like that on it I would
probably chuckle and think the person got bilked out of the $9.95 it
apparently costs. It may of course be very good, I have no idea, I just
don't hold certification programs in very high regard in general.

Give a good graphics guy some $$ and he'll make you one of the best
certificates that your $$ can buy...that does not mean that you can actually
program in the language thats written on the certificate...
When I was learning computers I studied COBOL, Hated it and cant remember
crap about it now...not even 2 lines...but my (old) certificate says I'm
pretty good at it :-)
Basically it all comes down to how good you can actually prove yourself in
your field..certificates most of the time are not worth the paper they are
printed on but look good once you hang it on the wall ;-)
Just my $0.2

Unless they are internationally and industry recognised like the
Novell, Cisco, Oracle or Microsoft certificates it's probably not
worth the money (if any?) involved in obtaining it. You would be
better off spending your time working on a solid portfolio that
showcases both sites AND code that you've written. If you already have
those then I don't see how that expertrating thing can hurt, but don't
bank on it holding too much sway.

Hi!
I saw the Pear packages that are originally stored in
/usr/local/lib/php/****. This occur when I compile PHP. Problem is they
are different from the ones I downloaded from the pears.php.net website.
So, I enclosed those files into the website's directory, along with all
other website files. That way, I can use those instead of the one from
/usr/local/lib/php/****. However, I have a problem. When I run the web
script, PHP still use the Pear files in /usr/local/lib/php/*** instead of
the one I use along with the web files. I tried the include and require
function but no luck.
Why is that? What workaround do I need on this?

php is probably searching for includes in /usr/local/lib/php first. Also,
consider reinstalling what you've download from pear using pear's cli; `pear
install DB`, for example

HTML is the only method I've ever used. If it's off, I don't think you'll
find a solution. For those that have it on, at least you'll "see" them.
Another trick that might help, if you're mail server can handle it, is to
have a reply-to address like this:
bounces-<id>@domain.com
Some mail servers can be configured to ignore the '-' and everything after
it, letting you receive all your bounces at one address, but knowing by the
'To' field which member it is coming from. I know this doesn't address your
problem of being able to see who actually reads the message, but it will
help you know who isn't even getting the message to begin with.

Hey Rob,
Thanks for replying.
Yep, am going with html but am having a few problems....yahoo and hotmail
totally screw up the email and I dont get any confirmation :-(, after going
into view-> source I see that the IMG src address is being over written by
them..
Codes pretty simple (but works) you can compare it to your code if you need
to.
//PHP file
$connected=mysql_connect("$hostt", "$userr", "$passs") or die ('I cannot
connect to the database because: ' . mysql_error());
mysql_select_db ("$db");
$query = "insert into read_member values('$mem')";
$result = mysql_query($query);
if(!$result){ echo 'Info not inserted.'. mysql_error();exit;}
$mimetype="image/gif"; // Mime type of file
Header("Content-type: ");
readfile ($filename);
and in the HTML mail:
test <img
src="http://domain/testing/test_pass_image.php?mem=Ryan1&filename=dot.gif";>

Ok - one thing to try...
I've noticed when sending HTML emails from my client, it defaults to sending
the pictures with the email. This makes it so that the picture links to the
email, instead of to your webserver. I unchecked that option in my own
client and sent an email to my hotmail account. I checked the source and it
was unmodified.
If you can try the same thing, let me know. If it still doesn't work, there
may be another method you can try, ie:
http://domain.com/pics/<id>/blank.gif
This might fool hotmail. You'd have to create a php file named pics and
configure your web server to run it as php, or just name it pics.php.

If you are running PHP as an Apache module (and not CGI) then a
correctly validated user will have their details in:
$_SERVER['PHP_AUTH_USER']
and
$_SERVER['PHP_AUTH_PW']
There is a whole chapter on this (16) in the manual.

You probably have to trigger the debugger by doing something like
this:

mmmh... i think your problem isn't in mkdir, it is in evil MAGIC QUOTES!
(they are on by default)
if you are getting the name of the directory from GET, POST or COOKIE, check
the get_magic_quotes_gpc(), else check get_magic_quotes_runtime(), if the
problem is in get_magic_quotes_runtime(), you can do
set_magic_quotes_runtime(0) beforegetting the directory name, so it won't be
quoted, but if the problem is in get_magic_quotes_gpc(), you will have to
do something like:
if(get_magic_quotes_gpc()) stripslashes($dirname);

actually, you can control your printer, look:
http://www.php.net/manual/en/function.printer-set-option.php
you have to do:
$handle = printer_open();
printer_set_option ($handle, PRINTER_ORIENTATION ,
PRINTER_ORIENTATION_LANDSCAPE);
printer_close($handle);
you've got many interesting options with this function.
( These functions are only available under Windows 9.x, ME, NT4 and 2000.
They have been added in PHP 4.0.4.)
and you can do something about the phase of the moon too, look here :P

As one of the comments rightly says: "Should be pretty obvious, but in
case there is any confusion... The printer in question is one that is
connected to the _server_, not the _client_."

Pardon me if this subject has been discussed, but a search of the
archive didn't bring up much of anything.
Bear with me while I dish out some details. My question concerns the
efficiency of using multiple file includes versus storing segments of
data in one include as arrays or functions.
While rebuilding the core of my web site network and, after reading some
negative things about file includes, I was forced to rethink how I am
structuring things.
Here are some details:
*One domain serving, with around 5 sites as subdomains currently and
more soon to come.
*Each script on every site includes a global file that has sessions
stuff and network-wide functions.
*Each script includes a header.php file for the specific site's layout.
*Each script includes a footer.php for ditto.
*I am currently on a virtual server, but obviously will need to move on
to a dedicated very shortly.
It is my understanding, as disk reads are so slow, that it is not a good
idea to include multiple files. I always knew this, but I never really
thought about it.
While thinking of how to optimize it, I considered merging header.php
and the global file as one. However, I then realized some scripts
access the database before including the header as to dynamically change
meta tags (say, for Articles). I could use output buffering but, well,
I'm not going to.
So I was thinking of making one include file that contained the following:
The former "global" contents (which I'd have to use a batch file to
manage this section of the file for all sites at once, no big deal),
"header.php" as a function, and the same for "footer.php".
My main question is, will this, with any certainty, be more considerably
more efficient than simply including three files? Would it be more
efficient to put "header" and "footer" in arrays? Keep in mind I'd have
to use eval() on "header" as all of my headers contain some php code.
Another method that would involve using eval() would be to store the
headers and footers in databases, but I highly doubt this would be more
efficient than storing them in arrays or functions.
Another situation, which I am quite certain would benefit from using a
function instead of an include, is that of scripts using forms. These
forms need to be included on more than one line, such as when the data
is empty or invalid and the form needs to be shown again. But forms are
relatively small compared to most of my headers.
So there you have it. How does an include compare to a function or a
function to an array? Is there a big difference in how the data is
stored in memory with a function versus an array? Would one choice be
more efficient on a virtual server, while another more efficient on a
dedicated (because of memory considerations)? I'm going to just assume
the database is not the most efficient choice here.
Thank you to all those who will respond, and even those who simply read
this whole message.

Rob, you will find people who religiously avoid includes have pages that
include dozens and dozens of images there by negating the microseconds
gained by not using includes. I will refrain from commenting on the
rest of the mail primarily because i feel trying to shave a few
milliseconds here or there by changing the includes, moving from double
to single quotes etc are all futile efforts. Real speed and scalability
comes from algorithms backed up by tight coding.

Thanks for the reply. In my case there aren't many external files
associated with the script. 1 css file per site and no images except on
a few very specific pages.
Adding images does not negate the shaved microseconds. I see what you
mean, but it doesn't literally negate the saved load. The images would
be there whether or not the includes are used. I'm sure there are
millionaires out there who still pinch pennies.
That being said, I do appreciate your point, and I'm not one to go
overboard with these kinds of things. However, it is quite simply a
matter of three ways to do this with one being faster. Why would I, for
something so fundamental to my application (used on every pageview
across the network), not use the fastest method unless it brought some
great inconvenience to me?
Since I am already restructuring things, it would not bring about much
inconvenience to me. I do expect my sites growth to be quite
substantial over the coming year, so it can't hurt to pinch my pennies
now, even if I currently have an embarassment of riches.
Some day a millionaire might lose everything, except for the jar of
pennies he has on his dresser.

Rob, you will find people who religiously avoid includes have pages that
include dozens and dozens of images there by negating the microseconds
gained by not using includes. I will refrain from commenting on the
rest of the mail primarily because i feel trying to shave a few
milliseconds here or there by changing the includes, moving from double
to single quotes etc are all futile efforts. Real speed and scalability
comes from algorithms backed up by tight coding.

On a busy site (where the milliseconds start to matter) the chances
are that the operating system has your include files cached so the
load time is probably not a factor. If you install some of the php
token caching systems (zend and others) the speed is even better.
As to using header and footer includes I found that system really
frustrating trying to follow the html. What I have switched to is
templates where the site layout is a template and each php page
generates the content and passes it one include file that does the
final mix. this way my html developer has control over the html and
can edit it as one file most of the time.

I have used templating for specific projects in the past (and never
really liked it), but for this group of sites I handle both ends, so it
loses a lot of its worth. The factor of a caching system like Zend is
something I have overlooked. Currently, I wouldn't assume my virtual
host uses it, but it is something I have planned to purchase when I make
the move to a dedicated server.
As for trying to follow the HTML in an "include system", I don't have
too much of a problem with it personally. Perhaps because there isn't
much to my HTML, as I try to stick with a basic XHTML document layout
that can be manipulated by CSS. In other words, I never really have to
edit my HTML, except for the static text within when the need be.
Thanks for the info. I suppose I'll just stay with the includes for
this round and if I know of a better way next time I do my "spring
cleaning"--which probably won't have the coincidence of falling near
spring again--I'll run with it.

Gentlemen I do believe I have been misunderstood. What I meant was that
there are ways in which you can save pounds perhaps by the bucketfull
with possibly much less effort. For example I recently ran into a $1000
software where the most commonly used query was running against a table
that had a non-numeric primary key. This same key was being used in
multiple joins. Surely that can be optimized to get a huge gain in
performance?

Processing templates also consumes a bit of extra clock cycles.

Does anybody know of a licensing system or tutorial that uses mysql or a
text file. I want to add some sort of license control to the web app, eg if
it's a 10 user license, only 10 people can be on that site at a time.

Harry,
This could be due to a setting in your php.ini: short_open_tags = off
Either set this to "on" or use <?php phpinfo() ?>

Hi there
I have to make use of embedded pdf files in my page (management decision, please dont
argue with me on this one, not my choice).
I there a function or somthing to detect the presence of adobe reader to make sure the
client has it installed, before
continuing with displaying it in the browser.
I was thinking of trying to do a find the adobe.exe file, but I dont think that to
smart solution.
Kind Regards

Hello
I understand you are planning to display a PDF file inside a browser, yes?
I believe it would be a security major risk if a server side script was
able to list available applications on the client side. This may be
possible with M$-script technology, but I would be very worried if it was
possible with PHP. Please correct me if I talk nonsense...
Maybe a link to Adobe's Acrobat Reader download page is your best bet.
