That's overkill indeed and can make for some cool flaws on you
filesystem too. When an unmount won't succeed the next execution via
cron will fail since the mount point already exists etc.

Every few seconds an update over to 2 systems is somehow weird. I think
it is very intensive and like I said if somehow one part of the syncing
'hangs', it can fill memory or bandwidth very quickly.

So, I can't still figure out what has to be done over to these computers
every minute or whatever. The situation is not really clear to me.

Easier in a cron:

scp userB:/path/file /tmp/
scp /tmp/file userC:/path/

Scenario #1:
B&C can't talk for a reason.
Ergo, you SHOULD use A as a go-between

Scenario #2:
B&C could talk if you wanted them to.
Install SSH key-pairs on B&C and then use rsync over SSH

There's still no PHP involved, really...

Maybe there should be, in that the two programs should, perhaps,
expose something as web services via RCP, REST, or SOAP, but not from
what has been explained so far...

OP:
Please give us the "big picture" of what B&C are doing, and what info
needs to go back and forth.

This could change the answers dramatically.

Or not. :-)

Good luck! Sounds like that might be the best solution since you have
such specific needs.

The whole signature thing was just some friendly prodding because I
see them all over the place. I just happened to be between things at
work enough to waste some time on it. I even threw in the ;) to
hopefully get that across. :) I'd better stop typing now before tedd

Hey, don't jump bad on my ass, I was just commenting about the point
you raised. :-)

I think this got out of hand anyway -- public apologies to anyone who
took offense.

valgrind is an excellent tool for this sort of thing.

There are several popular "standards" out there.

The PEAR coding standard and the Zend one tend to get mentioned a lot.

The most important thing is to be consistent yourself, rather than to
follow a specific standard.

Anybody halfway decent can follow what you did if you are consistent.

They ARE consistent with the underlying libraries, which is more
important, really, because that means you don't have to waste hours
figuring out what PHP did to shoe-horn the other library's functions
into some other system.

SPM decided to move stuff to a different place, namely inside of a
/usr/share/php/PEAR directory, instead of just /usr/share/PEAR.

So change your include path and be done with it.

Don't redirect to this.

Your session data has "wi/madison" in it, redirect to that:

header("Location:
http://precube.com/$_SESSION[state]/$_SESSION[shortname]");

If mod_rewrite gives you the willies...

You don't really NEED it here...

Just don't create /wi/* directories, and use $_SERVER['PATH_INFO']
instead.

Store all the school data somewhere else, and let the PHP/AJAX spew it
out as needed based on the URL, with only an index.php file running
the whole site.

This line does the actual rotation, and, along with $degrees = 18, is
all you need to add to the other script.

You can add them here, after the image is resized, and you are done.

No textbook, but here's some advice...

Think of a variable like a house address for an actual house.

123 Maple Street

An array is just an apartment building:

125 Maple Street, Unit 1
125 Maple Street, Unit 2
125 Maple Street, Unit 3
.
.
.

When you want to talk about the whole array (building) you can use
just the street address.

If you want a specific unit, you have to add the [$unit] part.

There is no way to know when they quit/closed the browser or even just
walked away and let the session time out.

But you *CAN* easily log the last time they accessed any page, by
adding something like:

$query = "update user_profile set last_access = now()";
$access = mysql_query($query, $connection);
if (!$access){
  //error handling here
}

So you'll know the last time they actually DID anything, which is
probably more interesting than recording when they closed the browser
if they were looking at some other tab anyway.

Something like this, perhaps:

preg_match('/^((19|20)[0-9]{2})-([0-1]?[0-9])-([0-3]?[0-9])$/',
$input, $date_parts);
var_dump($date_parts);

This doesn't completely rule out bogus dates such as 2008-02-30 however.

I think MySQL would just convert that to MAR 1, 2008 anyway...

But if you want that degree of comparison:

list(,$year, $month, $day) = $date_parts;
$unix = mktime(1, 0, 0, $month, $day, $year);
list($y, $m, $d) = date('Y-m-d', $unix);
if ($year != $y || $month != $m || $day != $d){
  //handle invalid date input here
}

If you do all of that (which is really 5 lines of code) you should be
pretty sure it's a correct/valid date.

Doesn't checkdate() do the sanity check for a valid date?

It is customary for geographically-challenged job postings to include

hi,
maybe my question is not exactly for php list, but since php IS involved and since you are such a great people, I hope the question will not disturb you :D

I have a project for one electric wholesale store to build a web site. it has to be dynamic, php, database driven web site.
it will have "standard" pages (news, links, about us, history, contact us, contact form, faq, business partners,...) and product catalog. my client wants to have ability to have different prices for the same product for different customers. means, when you come to the site you are going to see "public" prices. after customer logs in he's going to see some products with different price.
customers (only registered ones) will be able to select products and create an order. of course, after he submits, he's going to get confirmation email, and one email will be sent to store etc.

payment is not involved, the store will charge them later, probably monthly or something like that (not part of my project).
even there is not payments or any other sensitive data will be transfered over the internet, I suggested and the store owner accepted to use login to membership area and ordering process SSL.
 
project has administration area too to change content of the site, add/edit/delete (single) products, add/edit/delete customers.
I have to build also script to update products using excel sheet - the easiest way to make update of products for store owner.

I think I covered almost everything. there will be some more stuff, but noghtin "critical" (new customer registration page, manage my profile, order history,...)

now, I didn't have such a big project "on side" ever. and I by default ALWAY suck in calculations how much time I need for a project and what to charge.
I think I need about 120 hrs (3 weeks) to build this baby (without design part).
I need your opinion. is it enough time (yes, I know it depends of how fast I program :D Let's say, average fast :))
and what are fees these days for such a project? I lost track. $75/hr is lowest price today or I can't ask more than $50/hr?

thanks for any advice/help.

You can ask whatever you want as long as your customer thinks it's
reasonable. (not a joke).
Given that you're an individual bidding on a single project, you might
want to consider fixed price instead of time and materials.

As for estimates wrt time and effort - if those were available on a
mailing-list based on about 30 lines of project description, this list
would be full of project managers, all with desperate needs to estimate
how long <something> takes. :-)

I have this:

<?php if (trim($_SESSION['nowtoctype']) == 'thistype')

{print '<a href="page1.php">page1</a>';}else{print '<a href="
page2.php">page2</a>';} ?>

I will get the error:

Notice: Undefined index: nowtoctype in ...

If the variable has not yet been defined...

Is there a way to check if this var is already defined? ... (and then I can
define it - if not)

    Check out isset(): http://php.net/isset

<?php
    if(isset($_SESSION['nowtoctype']) && trim($_SESSION['nowtoctype'])
== 'thistype') {
        echo "<a href=\"page1.php\">Page 1</a>\n";
    } else {

designing, I'd like to build a JavaScript menu navigation scheme. I
need it to be driven programmatically, because the Admin users can
add and remove tasks to the system or to a given user at-will.

I already built a similar thing using CSS-only menus, but it just
wasn't aesthetically flexible enough. I am exploring other options,
but I am wondering if any of you have done something similar and have
any samples or advice.

attached mail follows:

Was just upgrading to 5.2.5 and used the same configure line as I used
for 5.2.0. Got the following notice:

"Notice: Following unknown configure options were used:

--enable-pic
--with-dom
--with-png
--with-xml
--enable-track-vars
--enable-trans-sid
--enable-yp
--enable-mbstr-enc-trans
--enable-dio
--enable-mcal
--with-jpeg"

Safe to assume those were deprecated?
