[PHP] Getting an advanced foreach to work

[Jonas Rosling]

I got the code as follows bellow. I'm having some problems to get it to
work. Maybe some of you are able to help me a bit.
First of all I got an array (salespersons) containing names of dynamic array
names. For example it can contain Johan, Mark, Jenny, Bill etc.
By calling for the possision in the array based on $count I'll get the name,
and that's the name of another array. The problem is in the foreach
with ( { } ).

$count = 0;

// Loopa så länge räknaren är mindre än storleken av arrayn $salespersons
while ($count  count($salespersons)) {

foreach (${$($salespersons[$count])} AS $key = $value) {

echo htmlentities($key).' - '.$value;

$count++;
}

}

Anyone?

I see you have solved it - just one comment.

This particular line will get evaluated every time. If you have a large 
number of elements in $salespersons, it will slow things down considerably.


From a performance point of view you're much better off doing:

$sales_count = count($salespersons);

while($count  $sales_count) {


The only reason to leave the count in the while statement is if you are 
adding/removing to that array within the loop, otherwise chuck it in a 
temp variable and use that instead.

[PHP] date iteration

[Dave Goodchild]

Hi all, I am writing an app that runs a prize draw, wherein the admin
chooses the duration by adding a start date and number of days for the draw
to run. These values are passed into a small function that generates an
array holding the start date, end date and all dates in between as follows:

function generateDates($first, $duration) {

   $dates = array();
   $date = getdate(mktime($first));
   $month = $date['mon'];$day = $date['mday'];$year = $date['year'];

   for ($i = 1;$i = $duration; $i++) {

   $added = getdate(mktime($day++ . - . $month . - . $year));
   $dates[] = $added['mday'] . - . $added['mon'] . - .
$added['year'];

   }
   return $dates;
}


$series = generateDates('23-05-2006', 20);
var_dump($series);

...when I var_dump the array the iteration stops at May 24 - I am looking
into it but does anyone have any ideas why this is sticking ie is my date
arithmetic wrong? Cheers.

[PHP] One works, but the other doesn't

[Jonas Rosling]

I find this problem very strange. I've got two parts of code (allmost the
same) in different TD's with vars and arrays (with same name) but it's only
the top code that gives result. I've allso tryied to rename the vars and
TD's in the bottom without any luck. The only vars/arrays that I haven't
mind changing name on yet are some dynamic, like:

${$row[0]} = array();

${$row[0]}[$row[1]] = $row[2];

But I think this could be the main cause, but I'm not really sure. If I
delete the top code the bottom works. Any idéas any one?

Your mktime() usage is off. I think you're confusing it with
strtotime(). Please see the function arguments in the docs:

php.net/mktime
php.net/strtotime

Also, inside the loop, instead of using getdate and then
concatenating to form the date string, consider using
the date() function to do it.

php.net/date

Without seeing the whole code involved, my guess is you're resetting
the array with every loop.

Guesses don't help but that's all we can do without seeing any actual code.

[PHP] Can a script run twice?

[Lester Caine]

I'm having very occasional problems with my PHP5 applications which only 
seem to be explained if the script is run twice.


Example - page has 'Add Ticket' button, which adds a record and marks it 
as being processed by the location that created it. 99.99% of the time 
no problems, but just now and again there are two records, with 
different primary keys - so the database bit worked - but with very 
close now times and identified as being at the same counter. The next 
page does not have the 'Add Ticket' button, so it would seem the first 
script was trigger twice?


Am I simply going mad ( which is the logical choice ;) ), or is this 
something that can happen and needs to be handled?

This can happen if a page contains a reference to an empty URL. For 
example, img src= / would cause the page to be loaded twice in some 
browsers. That'd be the first thing I'd check.


Is the 'Add Ticket' button a GET or POST request? If it's a POST then 
chances are the script itself has a logic error since the user would get 
asked if they wanted to repost the data. If it's a get then you've 
violated one of the cardinal rules of web-based application development 
- GETs get, POSTs do.

Man you do things the hard way. Why use all those variable variables?


$my_data = array();

// Loppar igenom raderna
while($row=mysql_fetch_assoc($result)) {
$code = $row['salesperson_code'];

if (!isset($my_data[$code])) {
$my_data[$code] = array(
'description' = $row['description'],
'total' = $row['totalt'],
'antal' = $row['antal']
);
} else {
$my_data[$code]['description'] = $row['description'];
}
}

var_dump($my_data);

MUCH easier to read and you'll find debugging LOTS easier.

RE: [PHP] Can a script run twice?

[Chris Kay]

OK I found this out last week... if its not a coding error... its this..

There is a bug with IE7, I have some billing scripts for a large Sydney ISP
and I was working on a script on my laptop which I recently updated to
IE7... after tipping my hair out for a few hours cause I was certain it was
not a coding error I decided the run the script from my PC which was still
IE6 and would u believe it, the script only run once

I did some searching on (good old faithful) google and did discover a few
bugs with IE7... whats this have to do with PHP u ask... one was a session
bug.. and with my double script running bug which I could not find any
information on... I decided to lock the site to IE7 with javascript and told
the ISP to roll back or stay locked out

A lot of money @ stake... damn u Micro$oft...

Man you do things the hard way. Why use all those variable variables?


$my_data = array();

// Loppar igenom raderna
while($row=mysql_fetch_assoc($result)) {
$code = $row['salesperson_code'];

if (!isset($my_data[$code])) {
$my_data[$code] = array(
'description' = $row['description'],
'total' = $row['totalt'],
'antal' = $row['antal']
);
} else {
$my_data[$code]['description'] = $row['description'];
}
}

Well, I'm kind of a newbie at this. So you think this will solve my problem?


Look at it this way - Which one is easier to read? Which one do you
think will be easier to work out what's going wrong?

Readability of your code will help you so much. If you come back to
this in a week, will you understand what's going on?

I don't know if my code will give you *exactly* what you want - test
it and see (backup your existing php file, change this code, see what
you get).

 I see you have solved it - just one comment.
 
 This particular line will get evaluated every time. If you have a large
 number of elements in $salespersons, it will slow things down considerably.

Quick amendment to this statement: PHP stores the number of elements in
a userspace array directly in the internal zval, so calling count()
simply reads that value no matter how big the array is (in algorithmic
terms, it is O(1)).  In other words, count(array(1)) is every bit as
efficient as count(array_pad(array(1), 100, 1)) if you eliminate the
cost of creating the 100 element array.

Having said this, there is potentially significant overhead involved in
calling a function as opposed to a variable lookup, and so you might end
up saving a few microseconds.  However, because count() is O(1), it will
be a constant amount per loop.  If you need to eke out that much extra
performance, you may be better off using a profiler to see where the
real bottlenecks in the code are.

Greg

 
 From a performance point of view you're much better off doing:
 
 $sales_count = count($salespersons);
 
 while($count  $sales_count) {
 
 
 The only reason to leave the count in the while statement is if you are
 adding/removing to that array within the loop, otherwise chuck it in a
 temp variable and use that instead.

RE: [PHP] Need Help Please

[Jay Blanchard]

[snip]
While tabindex is a neat thing to use it does not necessarily give focus
to the first element of the form, it merely dictates the order in which
form elements will be given focus when the tab key is pressed. The 
action may vary from browser to browser. Likely, when going to a form
with tabindex defined, none of the elements will have focus until the
tab key is pressed once, at which time the element with tabindex=1 
will get focus.

If you want to give focus to the first input element of a form you must
still use a JavaScript widget to place the focus there after the entire
page has loaded, tabindex will make sure that the cursor goes in the 
order you wish to go in after that.[/snip]

Try to use Firefox to debug your javascript.
I guess, there are some javascript error.

I confirmed before I sent the above e-mail that tabindex did not work in

[PHP] 3DES w/ openssl_{csr,pkey}_new ?

[Brian A. Seklecki]

Does anyone know how to specify the encryption cipher used in this 
funciton as documented in OpenSSL's genrsa(1)?


Why isn't the encryption method a value in [array configargs] ?

   -des|-des3|-idea
   These options encrypt the private key with the DES, triple DES,
   or
   the IDEA ciphers respectively before outputting it. If none of
   these options is specified no encryption is used.

Or is the encryption method a value that can be specified in 
config= and req_extensions= ?


Right now generated private keys look like:

  -BEGIN RSA PRIVATE KEY-
  Proc-Type: 4,ENCRYPTED
  DEK-Info: DES-EDE3-CBC,FA81C573DFD21B7D


Which is 3DES, but some systems support AES, IDEA, Blowfish, Twofish, It 
depends on the OpenSSL config.


Idea?

TIA,

For example, I can place php code within a html document and it will

So, how does placing ?php do_bad_stuff(); ? within any image cause problems?

However, if the problem is real, then why not just resample or alter 
the image in some fashion? Surely, that would cause any embedded code

Dotan:

What kind of documents and how to do want to present them?

PHP can generate html code and place any text file within in it -- 
it's simple a matter of arranging things the way you want it to look. 
For example, you might want to review:


http://www.weberdev.com/get_example-1233.html

In fact, you can do that without php by using a shtml and includes.

But, more specifically, I need to know more about what documents you 
have and you what you want to do with them.

Thanks for the example, Tedd. That script would work if I already had
the files in HTML format.

I have about two hundred .doc files that I have archived over the
years. Now that I'm rid of windows I would still like to use them. I
figure that the easiest way to still view the documents, and make them
available for others in my faculty, would be to publish them on
dotancohen.com . However, I'd need to convert them from .doc format to
HTML before I can put them on the web.

I know that I can just drag it all over to a winbox at the university
and convert them one-by-one in Word, but I'd rather not do that to 200
individual files!

I looked at this briefly once, and you might find the OpenOffice.org

OK this is getting interesting.

I could not believe that double clicking a link would run the link 
twice. It just does not make any sense. So I've been round the browsers. 
IE does NOT process the link twice how ever I try and since all the user 
sites are IE they should be OK.
Moz, Firefox and Sea Monkey *DO* run the link twice, and any code 
attached to that link.
I can't believe that this has not surfaced before. I should not need to 
prevent duplicate actions, but it looks as that is required by the

Check phpinfo(), particularly SCRIPT_FILENAME or REQUEST_URI or 
SCRIPT_FILENAME in the Apache Environment section, and everything following 
_SERVER[REQUEST_URI] in the PHP Variables section.


But why not just put the appropriate header in the subdirectory you are using?

Why not? Why is it the browser's responsibility? Are you suggesting that
when I click twice on a link that runs javascript on every link that it
should only work once? Do you think javascript enabled links should work
differently than standard links? Have you read the HTML spec for the
anchor tag? This is deeper than the presumption that it should work one
way and one way only. Personally I think IE does it wrong. Also I use
linux and I'm very very likely to use the middle mouse button to popup a
link into a new window, and I might do it twice. Or I might do it once,
close the window, then proceed through the link. Either way, all these
actions mimic a second click. You're server side code should be more
robust and never ever trust the user or the browser to do what you want
:) Also, just for giggles and farts, I might hold down ctrl+r on the
target page. Is that any different than two clicks?

[PHP] PHP SNMP

[Pavleck, Jeremy D.]

Greetings,
 Seem to have a bit of a problem I can't figure out. I'm trying to query
servers via SNMP with PHP's snmpget function. Everything seems to work
fine, no problems at all - except I'd like the web page to print the
string value instead of the numeric value (I.E. OK for the Compaq Drive
Array vs 1).

 Now I've configured everything as best I can tell, and I have the page
loading the appropriate MIB file (
snmp_read_mib(/usr/local/share/snmp/mibs/CPQIDA.MIB)). 

 Running it from the terminal via 'php mypage.php' returns all the
correct values, I see Ok, instead of 1. But accessing it via the web
produces nothing - no output. It doesn't matter how I set the get, I've
tried varying it with CPQIDA-MIB::cpqDaCntlrBoardStatus.0,
cpqDaCntlrBoardStatus.0,
.iso.org.dod.internet.private.enterprises.compaq.cpqDriveArray.cpqDaCom
ponent.cpqDaCntlr.cpqDaCntlrTable.cpqDaCntlrEntry.cpqDaCntlrBoardStatus.
0 - all work fine running it via the terminal, but not via the web
page.

Does anyone have any ideas at all about this? Anything else I can check?
If I snmpget the numeric OID (.1.3.6.1.4.1.232.3.2.2.1.1.10.0) it does
work, but only returns the numeric value.

System Info:
PHP 5.0.5
Net-SNMP 5.1.1

Php compiled with --with-snmp and --enable-ucd-snmp-hack

Thanks.

[PHP] New PostgreSQL

[Martin Marques]

A new version on PostgreSQL came out with a security SQL-injection hole 
fixed. Reading the docs, I find that clients have to be rebuilt, and with 
changes in regard to the use of the libpq library.


Is there going to be a new version of PHP4 and 5 to ajust to this?

Here is the data:

No.

If you still see \' in your data after it's in MySQL, then you have
done TWO escapes, and should have only done ONE.


By the way, the right way to escape single quotes is by adding anothe 
single quote (this is SQL standard). Somthing like:

 Dotan:

 What kind of documents and how to do want to present them?

 PHP can generate html code and place any text file within in it --
 it's simple a matter of arranging things the way you want it to look.
 For example, you might want to review:

 http://www.weberdev.com/get_example-1233.html

 In fact, you can do that without php by using a shtml and includes.

 But, more specifically, I need to know more about what documents you
 have and you what you want to do with them.

 tedd

Thanks for the example, Tedd. That script would work if I already had
the files in HTML format.

I have about two hundred .doc files that I have archived over the
years. Now that I'm rid of windows I would still like to use them. I
figure that the easiest way to still view the documents, and make them
available for others in my faculty, would be to publish them on
dotancohen.com . However, I'd need to convert them from .doc format to
HTML before I can put them on the web.

I know that I can just drag it all over to a winbox at the university
and convert them one-by-one in Word, but I'd rather not do that to 200

If that's the case, why don't you just use the export as web page or save

Double-clicking is a GUI event, the two mouse clicks bound together

computer's operating system.


It is certainly possible to single-click once to submit a form, then 
single-click again to submit the same form a second time before the 
first request has completed.  This sends two submissions to the 
server and is a common problem on pages that have left this door wide open.


Before I wandered off into the dense jungle of possible browser bugs,

There is no way you can prevent your users from clicking more than 
once unless you visit them and physically restrain them, a strategy 
which would quickly exhaust your resources and soon curtail your 
personal freedom.  Instead, you have to assume that some of your 
users WILL multiply click (whether deliberately or accidentally) and 
plan for that contingency.  Multiple submissions can happen for a 
variety of reasons:

- maliciousness;
- accidentally clicking twice (happens to me when I've been working 
too long: my mouse button finger sometimes just clicks of its own accord);
- getting impatient with a form submission that takes more than a few 
seconds and either clicking again or reloading the form to try again.


A client-side solution is for Javascript to disable the submit button 
onsubmit(), however this wouldn't prevent the user from reloading the 
page and submitting a second time and wouldn't work at all if 
scripting were disabled.


A server-side (and therefore more robust) solution is to accept only 
one form submission from each user/session.


An additional strategy to make your system more robust is to use 
three pages for your form submission:


1) the form itself, which submits to:
2) the script that processes input, which redirects to:
3) the page that displays the results (or is the next form in a sequence).

Even if the user reloads the results page (3) they won't be 
resubmitting the form (1) or repeating the input processing (2).

[PHP] How to disable PHP's POST caching?

[Adam Zey]

PHP seems to cache POST data, and waits for the entire POST to finish 
sending before it makes it available to php://input.


I'd like to be able to read the post data from php://input while the 
client is still uploading it. How can I cause PHP to make the POST data 
available right away instead of after the client finishes sending?


Regards, Adam Zey.

PS: As far as I can tell, PHP caches the entire POST in memory as it is 
being sent, but just doesn't make it available to php://input until 
after the client is done. Since PHP already has it in memory, why isn't 
it accessible?

Thanks for the example, Tedd. That script would work if I already had

Try searching the site using html, I found 85 examples that did

That's another source too.

If you were on a Mac, you could batch change the doc's into html 
pretty easily using AppleScript. You know that Word can save doc's 
directly to html.

Robert, you're absolutely right: there's no reason why my pages 1)  
2) can't be the same script posting to itself, and in fact the 
two-page model you describe is what I most often use in 
practice.  Perhaps I should have written step instead of page...


To take your point further, the process would be even simpler  more 
elegant if we stuck with a single script-page that displayed the 
form, processed input, and displayed the results.  If the server-side 
script is doing its homework, even separating out the results page 
isn't necessary since the form-processor has to be on guard against 
multiple executions regardless of the cause.  Reloading the script 
when it's in results mode isn't a big deal because it's smart 
enough not to process the same input twice.


There are occasionally some practical reasons for making the 
separation.  A few years back I wrote an action center engine that 
drove letter-writing campaigns run from many different environmental 
websites.  We let each client site host the introduction and the 
final thanks page, but the intervening 'action engine' that processed 
input and generated email  faxes was resident on our domain.  I'm 
sure many users were never aware that they'd left the client site for 
the duration of the processing.

Paul

Considering that everyone is putting in their $0.02, here's my suggestion.

1. Keep the form and processing on one page. The number of pages is 
not the problem -- double clicking is.


2. Start a session.

3. Initialize a variable that is incremented each time the page is 
refreshed per session.


4. If the variable's value is larger than one, then do something 
other than create and insert a duplicate record. Allow the user one 
insert per session or whatever.


If you want a very simple example that deals with clicks, see this:

http://xn--ovg.com/session

No matter how many times you double click that link, it will not 
increment more than once (at least that's been my experience). In 
other words, you can't get it to jump more than one.


If you want code, then see this:

http://www.weberdev.com/get_example-4349.html

second page is not seeing the already loaded ticket! Which I think is 
exactly where I started, the scripts seem to be processed in parallel 
and so do not see the data committed by each the other instance.


However now that I know what is going on I can deal with it, but the 
problem is much less in IE anyway :)

Add a token to the form and mark it used in the database on first

As I have indicated - the code SHOULD have delt with it - that is part 
of the problem :(  I just had not anticipated a browser splitting double 
click into two single clicks :)


But I'm now looking at other ways of flagging the 'second page' so that 
it knows that it is already being handled. That way I will not need to 
do so much work everywhere else in the code base. ;)

 Considering that everyone is putting in their $0.02, here's my suggestion.
 
 1. Keep the form and processing on one page. The number of pages is 
 not the problem -- double clicking is.
 
 2. Start a session.
 
 3. Initialize a variable that is incremented each time the page is 
 refreshed per session.
 
 4. If the variable's value is larger than one, then do something 
 other than create and insert a duplicate record. Allow the user one 
 insert per session or whatever.

I'd stay away form relying on the session unless your whole site relies
on the session. Your form should contain a hidden submission UID and
THAT should be used to determine if the form was submitted already. In
this way your form will still detect double submissions even when
sessions are disabled. Then the user needs to work quite hard to do a
double submission -- if you're using the POST method anyways :)

Rob.

I can see that, in theory, it might be possible to submit a form 
twice in succession so quickly that the first query is still being 
processed by PHP when the second query is initiated.  It's hard to 
imagine such a slow database or script, but perhaps all it would take 
would be a slow internet connection.


However, if you flag form submission in the session cookie I don't 
think it's practically possible to slip a duplicate by.  Because both 
form submissions would exist in the same session context, the server 
would know that a tenth or hundredth of a second previously the same 
session had submitted the same form, and could squelch it.

You're correct, of course. I was a bit confused, it seems.

PUT behaves as I described above. If you do a PUT request for the PHP 
script directly, the PHP script is called right away, and any attempt to 
 fread from php://input blocks until either the client is done sending, 
or some sort of buffer is filled (the fread occasionally returns with 
lots of data if you keep sending).


So, might I amend my question to, is it possible to disable PHP 
buffering PUTs, or Apache buffering POST? (Or is it PHP that just 
buffers the POST before actually executing the script, but post Apache?)


Essentially what I want is a persistant HTTP connection over which I can 
stream data and have the server-side PHP script process the data as it 
arrives, rather than when all the data is sent.


The only other approach I can figure out is to send periodic POST 
requests with the latest data, the downside of which is a huge increase 
in latency between data production and consumption.

Unfortunately, the requirement is that the script be able to accept data 
on port 80, and co-exist with an existing webserver at the same time. As 
far as I can tell, this requirement can only be fulfilled by running the 
script through a webserver. Also, sockets are not compiled into PHP by 
default, and stream sockets aren't included in versions below PHP 5.0.0, 
as far as I can tell. That sort of puts a hamper on socket usage.

It must be accessible to any client, no matter what sort of firewall or 
proxy they go through. The only way to absolutely assure that is, as far 
as I know, to use port 80. It is the only port that you can count on 
with a fair degree of certainty, if the user is proxied or firewalled.


I'd just as soon write my own simple webserver, but then it'd run into 
conflicts with existing webservers on port 80.


My current solution is to buffer data on the client-side, and send a 
fresh POST request every so many milliseconds (Say, 250) over a 
keepalive connection with the latest buffered data. The downside of this 
is that it introduces up to 250ms of latency on top of the existing 
network latency, and it produces a lot of POST requests. I would really 
like to eliminate that by streaming the data rather than splitting it up 
like that.

[PHP] Going through 2 arrays at once

[Pavleck, Jeremy D.]

 Greetings,

PHP Rookie here with a quick question - how do I go through 2 arrays at
once with different keys? 

I'd like to combine these 2 arrays into one:

for ( $i = 0; $i  sizeof($logicalDrive); $i++) {
echo $arrLogDrive[$i]br /\n;  
}

for (reset($logicalDrive); $i = key($logicalDrive); next($logicalDrive))
{
echo $i: $logicalDrive[$i]br /\n;
}

The first array returns things that the OID in the second array
represent. I.E. $array = array( 1= 'Controller Index:', 'Drive Index:',
Fault Tolerant Mode:', etc, etc);

While the second has the MIB name as the key, then the return value of
the snmpget:
CPQIDA-MIB::cpqDaLogDrvCntlrIndex.0.1: 0
CPQIDA-MIB::cpqDaLogDrvIndex.0.1: 1
CPQIDA-MIB::cpqDaLogDrvFaultTol.0.1: mirroring

What I'd like to do it replace CPQIDA-MIB::cpqDaLogDrvCntlrIndex.0.1
that gets displayed into the Controller Index: in the other array. 

I hope this makes sense. Sorry if it's super simple to solve, but I
tried a few things, and googled a few things, but I must have not found
the right thing I was looking for, as I still can't figure it out.

Thank you very much!

I have been reading this thread with much interest and think that

trying to accomplish? Skip past the persistency, etc. and describe the
problem for which you are seeking a solution. I have the feeling that
there may be a way to do what you want with PHP if you will describe the
process.
 

Essentially, I'm looking to write something in the same vein as GNU 
httptunnel, but in PHP, and running on port 80 serverside. The 
server-client part is easy, since a never-ending GET request can stream 
the data and be consumed by the client instantly. The thing I'm having 
trouble with is the other direction. Getting data from the client to the 
server.


The data going from client-server needs to be sent over an HTTP 
connection, which seems to limit me to PUT and POST requests, since 
they're the only ones that allow significant quantities of data to be 
sent by the client. Ideally, there should be no delay between the client 
wanting to send data and the data being sent over the connection; it 
should be as simple as wrapping the data and sending.


So, I need some way to send data to a PHP script that lives on a 
webserver without any buffering going on. My backup approach, as I 
described in another mail, involves client-side buffering and multiple 
POST requests. But that induces quite a bit of latency, which is quite 
undesirable.

Unless you have ANOTHER bug somewhere in those million lines of PHP

Which might maybe let you eval() that, or manage to include it or...

Why risk it?

Defense in depth.

It's not like a call to http://getimagesize is gonna kill you.

Even moving the image out of web tree and using readfile is fine for
all but the busiest servers.

[shrug]

I don't understand why people are so resistant to something so simple
that adds a layer of defense.



Again, I'm not disagreeing with anyone! Instead I'm simply trying to 
understand how this might work.


Understanding a risk is one step closer to providing a proper 
defense. Just placing an additional step is not necessary adding 
another layer of defense and in fact goes against the Simple is 
Beautiful security level that Chris Shifett addresses in his 
Essential PHP security book.


As for using eval(), that function ranks number one on his list to 
pay the most attention to with regard to security. I hope that no 
programmer would use an evalu() on an uploaded image -- but, that 
might be a way to make an image with embedded code do bad things. 
However, the programmer would have to be an accomplice in the attack 
by using eval() incorrectly.


In the past, I have used headers of jpg files to store information -- 
there's a lots of unused space there -- however, at some point, the 
program that deals with the image has to switch from this is an 
image to this is an executable piece of code for this to work. I'm 
trying to understand how that would happen.


If this is something that is real, then I am also suggesting that 
doing something with the image should screw-up any embedded code. 
But, before providing a defense, one should understand the threat.

I'd like to combine these 2 arrays into one:

for (reset($logicalDrive); $i = key($logicalDrive); next($logicalDrive))

something like:

foreach ($arrLogDrive as $key = $val) {

The first array returns things that the OID in the second array
represent. I.E. $array = array( 1= 'Controller Index:', 'Drive Index:',
Fault Tolerant Mode:', etc, etc);

While the second has the MIB name as the key, then the return value of
the snmpget:
CPQIDA-MIB::cpqDaLogDrvCntlrIndex.0.1: 0
CPQIDA-MIB::cpqDaLogDrvIndex.0.1: 1
CPQIDA-MIB::cpqDaLogDrvFaultTol.0.1: mirroring

What I'd like to do it replace CPQIDA-MIB::cpqDaLogDrvCntlrIndex.0.1
that gets displayed into the Controller Index: in the other array. 


I hope this makes sense. Sorry if it's super simple to solve, but I
tried a few things, and googled a few things, but I must have not found
the right thing I was looking for, as I still can't figure it out.

It sounds like you want to use a while loop and then iterate manually 
through both arrays, iterating both arrays once per loop iteration.

You're completely right about that. Maybe living too much at the edge of the

this way of thinking out my mind.



 Anyway, I understand... it's a pain in the ass. Whay you're doing wrong

 you have turned your solution into a problem and forgot what the real
 problem was.

this assumes there is a 'problem' - maybe Dotan is driven more or less
by a desire to see if he can do it rather than being up against some
deadline
or having his boss breathing down his neck waiting for a result?



I disagree. There is always a problem, the kind of problem you're referring
to is I'm lacking this knowledge, or I want to know how to do X, in his
case X would be converting word docs to html with a php script.

My first impression was that this was his problem, but deducing from what he
explained after, I'm certain this isn't the problem he wants to solve, but
rather a solution he came up but is unable to put into practice.

I think this time PHP is not the solution. A shell script interacting with a
third party tool, or a C program interacting with a third party library will
be a much more appropiate solution.

Tunelling arbitrary TCP packets. Similar idea to SSH port forwarding, 
except tunneling over HTTP instead of SSH. A good example might be 
encapsulating an IRC (or telnet, or pop3, or ssh, etc) connection inside 
of an HTTP connection such that incomming IRC traffic goes over a GET to 
the client, and outgoing IRC traffic goes over a POST request.


So, the traffic is bounced:

[mIRC] --- [client.php] -internet- [apache --- server.php]  
-internet- [irc server]


And the same in reverse. The connection between client.php and 
server.php is taking the IRC traffic and encapsulating it inside an HTTP 
connection, where it is unpacked by server.php before being sent on to 
the final destination. The idea is to get TCP tunneling working, once 
you do that you can rely on other programs to use that TCP tunnel for 
more complex things, like SOCKS.

[PHP] Formatting of a.m. and p.m.

The date function itself doesn't support it, but you don't need IFs.

To replace your example: echo str_replace(array(am, pm), 
array(a.m., p.m.), date(a));


And to do the replacement on a full data/time:

echo str_replace(array(am, pm), array(a.m., p.m.), date(g:i a));

which would output something like 12:52 p.m.

The difference between include and require is that if include() can't 
find a file, it produces a warning, and the script continues. If 
require() can't find a file, the script dies with a fatal error.


The difference between include()/require() and 
include_once()/require_once() is that if you do, say, require_once() 
twice, it ignores the second one. This is useful if your script might 
include the same file in different places (perhaps your main script 
includes two other scripts which both themselves include functions.php)

 Exactly what should be happening. The bit I have to work out is why 
 the second page is not seeing the already loaded ticket! Which I 
 think is exactly where I started, the scripts seem to be processed 
 in parallel and so do not see the data committed by each the other instance.
 
 
 I really don't see how this could be browser-dependent.  (Unless you 
 have cookies or session cookies disabled in your Mozilla browser?)
 
 I can see that, in theory, it might be possible to submit a form 
 twice in succession so quickly that the first query is still being 
 processed by PHP when the second query is initiated.  It's hard to 
 imagine such a slow database or script, but perhaps all it would take 
 would be a slow internet connection.
 
 However, if you flag form submission in the session cookie I don't 
 think it's practically possible to slip a duplicate by.  Because both 
 form submissions would exist in the same session context, the server 
 would know that a tenth or hundredth of a second previously the same 
 session had submitted the same form, and could squelch it.

These are called race conditions for a reason. They are racing against
all kinds of things. Network latency, filesystem, processor, etc etc.
Any one of these thigns can slow down one thread just long enough for a
newer thread to grab the session data before the older thread saves it.
Then the newer thread happily uses the stale session and voila duplicate
input. If you absolutely, definitely, for sure want to prevent this...
use some kind of locking mechanism. I'd suggest locking the table that
manages the form submission unique IDs until you've checked and, if
necessary, updated it. There's a reason pages load sequentially in
multiple frames when using PHP sessions... it's because PHP uses
locking. Are you using PHP native sessions or your own home cooked
system? Are sessions even activated? Did the user disabled sessions? Why
am I teaching you second year comp sci? :)

AJAX implies javascript, which means a browser. My situation doesn't

send data, which would have the same problem as sending many POST

The slight complication here is that you are iterating through an
indexed and an associative array.  There are two easy solutions,
building on each of the above loops.

As you don't care about the key of the second array you can convert it
to an indexed array using array_values().

$logicalDrive_indexed = array_values($logicalDrive);
for($i=0; $imin(sizeof($arrLogDrive), sizeof($logicalDrive)); $i++) {
echo $arrLogDrive[$i].: .$logicalDrive[$i].br /\n;
}

Alternatively the next() function works for indexed arrays.

for(reset($arrLogDrive), reset($logicalDrive);
current($arrLogDrive)!==false  current($logicalDrive)!==false;
next($arrLogDrive), next($logicalDrive)) {
echo current($arrLogDrive).: .current($logicalDrive).br /\n;
}

The second approach will have problems if either of the arrays contain
the value false.  Personally I would use the first loop.
