Re: [PHP] Question about session_id() and session_start()

[孟远涛]

thank you.
I read the source code and it helps a lot, now I know the behavior
of the code is consistent with the NOTE.
I think the reason is that If the 'new' session_id we want to set
already exists on the server, but does not exist on the client's
cookie, the server must send a set-cookie header to the client.

That wasn't the advice given. The advice given was to read the source

If you read the original question correctly, it's about a *new cookie* with
the *same session id*.

Second, if somebody is sniffing you he would also be able to grab the new
session id, and yours (old and new one) will be useless if he uses the new
session id before you do.
Avoiding session hijacking is not that easy, it's much easier to just use
an SSL connection. At least that protects you from someone sniffing on a
public wifi, but it does not help against sniffing viruses, malicious
browser extensions or cross site scripting attacks. Since it's off topic,
I'll end here. If you want to learn more, Google is your best friend!

I was thinking if I was sitting in a cafe and someone was sniffing and
tried to use my session info they would get a new session id where I would
still have my original one so they wouldn't be able to hijack mine trying
to reuse the same id I have since php would generate a new one

No?

How would it help preventing session hijacking if it was sending the a new
cookie with the same session id?

[PHP] Question about session_id() and session_start()

[孟远涛]

I find the Note in PHP document.
http://www.php.net/manual/en/function.session-id.php

"Note: When using session cookies, specifying an id for session_id() will
always send a new cookie when session_start() is called, regardless if the
current session id is identical to the one being set."

I feel puzzled about this feature. Even if the current session id is
identical to the one one being set, session_start will send a new cookie. I
want to know why session_start behave in this way.

Forgive my poor English. Thanks in advance.

[PHP] Question about PHP-CGI, mysqld and sudden spiking average load readings on Linux Virtual Dedicated Server running CentOS 6.3

[Gary Lebowitz]

I have noticed when doing a "top" via SSH on my GoDaddy virtual dedicated
server that every time a user logs in in the COMMAND column I see the
PHP-CGI process start to run, followed by mysqld. Often when these two
processes run I start to see a spike in average load, and sometimes this
spike spins out of control to the point that when trying to log on to my
Moodle 2.3.2 LMS I get an 500 Internal Server Error from Apache. Now, what
I'd like to know given the fact that I have only 2GBytes of RAM and am
sharing a processor with other users :-( is if there is any way to make
sure my PHP 5.3.3 is properly configured. I am given, for example, a choice
between CGI, fastCGI and Apache in my Plesk panel, and I am not quite sure
how to optimize things for my environment. I went to the Moodle.org site to
try and see what's the right setting, but it's not clear if the persons
writing there have a different setup or not. Unfortunately, it's impossible
to get specs on my VDS's processor from the fine folks at GoDaddy, and
perhaps there is just a simple processor power issue going on here, but I
only have 30 students and only a handful going in simultaneously. And at
times my average load can move from .08 to 1.5+ and all the way up to 2+
within the space of a few seconds. I should point out that at one point it
was discovered by GoDaddy technicial people that a user was running a rogue
process that overtaxing resources. But perhaps I also need to tweak my
installation despite this incident. Any help here would be appreciated.

[PHP] Question

[Silvio Siefke]

Hello,

i have compile PHP 5.4.8 on my Debian System. I have before Version 5.4.7. 
I delete before all old Files from PHP and then run the commands:

./configure --sysconfdir=/usr/local/etc --with-pear --enable-bcmath 
--with-bz2=/usr --disable-calendar --enable-ctype --without-curl

--disable-embed --disable-cli --disable-cgi --enable-fpm --without-apxs2 
--with-kerberos

make -j3 ; make install

But when i look in the directorys i miss pear and the php-cgi.

root:/usr/local/src/php-5.4.8# ls /usr/local/bin
php-config  phpize

root:/usr/local/src/php-5.4.8# ls /usr/local/sbin
php-fpm

Must under bin not be php-cgi and pear, or is my thinking wrong?


Thank you for help and Greetings

Well, that really depends on the payment gateway. Anyway it should of
course work if you have followed the documentation. Just want to let you
know that you're probably not going to get a in depth response on how to
use the payment gateway, since that is specific to your provider. The best
way of looking what you're sending to the server and back is using a packet
logger, for example wireshark. Though, make sure you run the capture on the
webserver ..

Re: [PHP] SOAP and Php question about authentication

[James Newman]

I agree with your response, the payment gateway insists that the
authentication I have been given is correct.  My question was more around
"was I using the function correctly".  It says authentication failed but
I've followed he documentation to the letter. Is there a way I can output
what the server is saying when a request is sent?

Re: [PHP] SOAP and Php question about authentication

[Curtis Maurand]

That's not a helpful answer.  I'd be curious at a real answer
for this, too.  I'm sure that there is something going on with
session management on the client side as authentication has probably
already happened, but the author doesn't know how to handle the response
to the authentication correctly.

I'm having a few authentication issues and I'm not sure if it's my code or

Just for the record: As noted on the manpage [1], your PHP version
needs to be >= 5.3.0.

Thank you Eric,

Date conversion is a popular issue when converting the language from
one to the next. 
I prefer to manage any date filtering outside of MySQL because sometimes the
fields are not clean or formatted correctly, and the DATEDIFF() of MySQL
just fails.
This failure can be devastating when dealing with a MySQL replication setup.
I gauge the MySQL process against the PHP process and determine which is
faster and which do I have more effective controls in.
I have found I have better flexibility and control of date filtering in PHP.

But squirrels will be squirrels...

Hello List,

I am using PHP V5.3.3

In my setup, the following lines give me errors stating that PHP cannot

error by changing your code to the following.



   $intDayCnt=$dteEndDate[$i]-$dteStartDate[$i];


$intDayCnt = ( $dteEndDate[$i]->format('m') -

Be sure to change the following line as well.

Actually for what I need this is exactly what i was looking for.  I am 
converting an asp page that was calculating this difference using VBA functions 
and I was trying to duplicate things as they were in that page.

I looked at this answer and see the date is from an array of a database and not 
2 fields with in the table.
While the DATEDIFF() is very useful in queries this will not help you unless 
both fields are in the table.

Try this example

$dteStartDate[$intCnt] = new DateTime($row[10]);
$dteEndDate[$intCnt] =new DateTime($row[11]);
$interval = $dteStartDate[$intCnt]->diff($dteEndDate[$intCnt]);
echo $interval->format('%R%a days');

since you have everything in database tables why not to do this
calculation
on database side which would be much appropriate place ?

/* columns
date_start = '2011-02-08';
date_end = ' 2011-03-04';
*/

select DATEDIFF(date_end, date_start);

http://dev.mysql.com/doc/refman/5.5/en/date-and-time-
functions.html#function_datediff


I looked at this answer and see the date is from an array of a database and not 
2 fields with in the table.
While the DATEDIFF() is very useful in queries this will not help you unless 
both fields are in the table.

Try this example

$dteStartDate[$intCnt] = new DateTime($row[10]);
$dteEndDate[$intCnt] =new DateTime($row[11]);
$interval = $dteStartDate[$intCnt]->diff($dteEndDate[$intCnt]);
echo $interval->format('%R%a days');


well then look deeper in the question:

"I have a page I am trying to create where I am comparing the values of two
MySQL date fields with the current date. One of the *MySQL Date fields 
*is a class start date,*the other* is the class end date."


all needs to do is modify his query.

[PHP] Question about date calculations

[Eric Lommatsch]

Hello List,

 

I am using PHP version 5.2.6.

 

I have a page I am trying to create where I am comparing the values of two
MySQL date fields with the current date. One of the MySQL Date fields is a
class start date, the other is the class end date.

 

First I need to calculate the number of days between class start and end
date. Then based on the number of days between these to dates I have to find
out how close the current date is to the class end date.

 

So far in looking at the functions that are available at
http://www.php.net/manual/en/ref.datetime.php I have not been able to figure
out how to do what I need to do.  Below is a snippet showing approximately
what I am trying to do.

 

=($dteEndDate[$i]-7) &&
$dteCheckDate<=($dteEndDate[$i]+1)) && $intDayCnt<16)

...

?>

 

My start date is 12/26/2011, the end date 1/8/2012 so the value for
&intDayCnt should be 13, but it is coming up as 0.

 

Also the check date which is 12/29/2011 is being calculated as after my end
date.  Can someone point me in the direction of what I need to do to have
the comparisons I am doing work.

 

Eric Lommatsch. 

[PHP] Question regarding passwords/security

[Paul M Foster]

Not sure how to ask this question... I've always eschewed consulting a
database on page loads to determine if a user is logged in, primarily
because of latency issues. For example, you could store a nonce like the
session ID in a table for a user when they log in. Then each time they
arrive at a page which needs certain permissions to access, you'd check
the table for the nonce and compare it to the actual session ID or
whatever to determine that they're properly logged in. This seems
reasonable but suffers from the lag on the database link's
query-and-response lag time. So I've always preferred some solution
where something is dragged along in a session cookie instead. Maybe
something like the hash of user login, email and user name, which
wouldn't be there unless you'd put it there on login. But this latter
scheme just seems inherently less secure than consulting the table.

Is there any concensus or overwhelming argument one way or the other?

Paul

It seems to me that your socket_select function is failing, maybe
because earlier code is failing. Check the return of socket_select
like this:
if ($changes === false) {
echo "socket_select() failed, reason: " .
socket_strerror(socket_last_error()) . "\n";
}

There's a bug in your first test (the php iteration). You're using $i
for the inner and outer loop, meaning that the outer loop will only
run once.  Try this updated example:
https://gist.github.com/1452696

On my box it gives(with microtime instead of your timer class):
php join.php
n=1000
Pure PHP iteration: 0.87661409378052

String join: 0.13562703132629

json_encode: 0.081185102462769

json_encode is the fastest one here.

[PHP] Question about performance between for iteration and extension function

[Lin Yo-An]

Hi folks,

I am in doubt of this, I thought pure php iteration is slower than calling
join or other extension functions.

but the result shows:  https://gist.github.com/b2a94c94ca66a55814d4

Using Pure PHP for iteration is faster than using join function. why ?
because of the php runtime typecasting ?

And json_encode is the most slowest.

Right -- I wasn't actually inquiring about how to access a data base,
merely the pactice of using a variable for the SQL -- In your example,
you are doing this as well, which fits in fine with what I was

I do this.  This means that when a user encounters an error, they can 
actually give you a meaningful error report which should reduce the time

While I am not a big fan of OOP, I do like PDO, and recommend its use.

This is a sample function I have to maintain a record based on POSTed 
changes:


function updatecategory($dbh, $x) {

 $sql = "UPDATE gallery_category
  SET category_name = :name,
  category_description = :description
  WHERE category_id = :id";

  $catname = fieldcheck($x['catname']);
  $catdescription = textfieldcheck($x['catdescription']);

  $stmt = $dbh->prepare($sql);

  try {
$stmt->bindParam(':name', $catname);
$stmt->bindParam(':description', $catdescription);
$stmt->bindParam(':id', $x['cid']);
$stmt->execute();
  } catch (PDOException $e) {
return 'Error updating category orders: ' . $e->getMessage();
  }

return "Maintained category " . $catname;

}

PDO is very efficient when you are looping through updates, and the 
error handling is simple to code.


Using a disciplined format keeps everything readable and easy to use as 
a template for additional work.

No need to review the code.  The first hunch I had proved correct.
 PHP opens with a less-than (left carat, or 'less-than') symbol, as do
HTML tags.  As a result, the browser interprets both as tags and tries
to parse them.

Viewing the source of that page upon selection of the PHP or HTML
options displays the code as expected.

Resolution:  str_replace('<','<',str_replace('>','>',$data));

Technically, only the less-than symbols need to be replaced, but
you may as well - as Charley Jordan says - Keep It Clean.

This might sound silly, but is it because it's being interpreted
somehow? I could understand the HTML going a little weird because of
this, not sure about the PHP, would depend what was trying to interpret
it...

[PHP] Question reading a file

[Tedd Sperling]

Hi gang:

I have a few questions -- this is my first one.

Please review this link:

http://webbytedd.com//perms/

This page simply reads the contents of a file of the user's choice and displays 
the file's data.

My first question is with regard to reading a file ( fread() ):

If the user picks the PDF file, the [1] First 20 bytes are: %PDF... 
If the user picks a JPG file, the [1] First 20 bytes are:  ...JFFIF... 
If the user picks a GIF file, the [1] First 20 bytes are:  GIF89a... 

Of course, the above is just reading/echoing the header for each of those files.

Likewise, if the user picks a TXT or CSS file, then [1] First 20 bytes echoed 
are the first 20 characters of the file.

However, if the user picks a HTML or PHP file, there are no [1] First 20 bytes 
echoed.

BUT, the ord() and chr() of the bytes ARE indeed collected and can be echoed as 
shown in statements [2] and [3].

So, my question is specifically "Why is the data gathered in the variable 
$content not echoed for the HTML and PHP files, but is for all other files?" 

Please review the code shown.

Cheers,

tedd

Where does the 9090 come from?

[PHP] Question about losing port number

[vince chan]

Hi:
I have a general question about  PHP:
So basically I have a link, and I want the href to be absolute., so I
do 'https://' . $_SERVER['HTTP_HOST'] . '/login' ; this gives me
https://127.0.0.1/login on my local; however, what i really want is
https://127.0.0.1:9090/login, it is missing ":9090". I also have tried to
use  $_SERVER['SERVER_PORT'],  but $_SERVER['SERVER_PORT'] doesn't give me
9090, it gives me 80.

Could anyone help me?
Thx

[PHP] question about Pear Auth and Pear MDB2

[Michael Mitchell]

Hi, I'm a bit of a newbie at PHP and programming in general.

Reading a PHP book by Larry Ullman, I  was given instructions to install
Pear Auth package and also Pear DB.

As the Pear website said that DB has been deprecated in favor of MDB2, I
installed this latter package.

However, I am getting this error message when I require Auth.php...


*Fatal error*: Class 'DB' not found in *
/Users/michaelmitchell/pear/share/pear/Auth/Container/DB.php* on line *150*
*
*
I'm not sure if this means I have done something wrong (if so, what?) or if
this is somehow indicating that the Auth package is referring to the
deprecated Pear DB package? or something else

Thank you if you can help.

Not unless it has
permission to do so.  Most likely, however, it can write to the temp
space such as /tmp or /var/tmp.

Re: [PHP] Question about directory permissions

[Andy McKenzie]

Sure.  The script runs with the permissions of whoever is running it.

In general, a PHP script that's a web page in linux will run by a user
called something like apache, apache2, www-user, or something similar.
 If you give that user permissions -- either directly or through their
group, often of the same name -- to write to the directory in
question, then the script will be able to write to it.

For instance:  on my Ubuntu 10.04 server, I want my script DW3 to be
able to write to /var/www/DW3/logs.  I leave ownership of everything
else as it was, and do the following:

$ cd /var/www/DW3
$ chgrp www-data ./logs
$ chmod 770 ./logs

Now members of the group www-data (at the moment only apache) can
write to the directory, as can the owner, but no one else can.  In
reality, I could probably have set that to 660, but I don't much care
about the slight added risk of using 770 in this case.  (If you're
confused by the numbers I used, check here:
http://www.yolinux.com/TUTORIALS/LinuxTutorialManagingGroups.html)


I hope that helps!

[PHP] Question about directory permissions

[Al]

I understand dir perms pretty well; but, have a question I can't readily find 
the answer to.


Under a Linux system, scripts can't write, copy, etc. to other dirs unless the 
perms are set for writable for the script e.g., nobody.


But, is there a way a script can write or copy within its own dir?

Thanks...

Subject: [PHP] question about preventing polling for more than once

I noticed that some websites such as
polldaddy<http://polldaddy.com/account/home.php> has
fascinating poll service. And I am just curious about how it prevents user
from polling the same poll for more than once. Or more accurately, I am a
dynamic IP user. And I found that if I have polled once for a certain poll
and after some time, I changed my IP when I got connected to the Internet
again, I cannot poll the previous one for the second time. So I am confused
how polldaddy <http://polldaddy.com/account/home.php> can figure out that I
have polled even if I had changed my IP. Is there any way to achieve that?

Thanks in advance.

I was hoping to simply give you a list of examples from google, but I couldn't
find any that showed exactly what you were trying to do, so... I wrote this

I can confirm this happens "all the time" in thunderbird, and always has 
for many years now, on all PHP NNTP lists.


However, the problem can be worked around simply, for some reason the 
timeout generally only happens with the first call to view a mailing

different PHP lists (like .soap .test and general) then when I open 
thunderbird I quickly click a list I *don't* want to see, then click on 
.general, .general then loads nicely as expected letting the other one

It's hardly a fix, but it works - may be worth checking if this is the 
case with the latest thunderbird revision and then reporting it as a 
"bug" (in either thunderbird or the mailing list software that PHP is 
running).


Best,

I have had this problem every day for years.  I can read a message and
then click another one and it times out.  It does this for hours at a
time.  Also, many times when sending a reply it times out.  Just learned
to live with it because I don't want mailing list mails either.

If there is a more appropriate place to ask this, I apologize. Please 
point me in the right direction.


I understand that the news server is based on a mailing list, but I 
can't handle another high-volume source dumping stuff into my email 
(even if I filter it into a separate folder) so I am trying to subscribe 
through the news group.


However, getting access seems to be hit-and-miss, since I more often 
than not get a message that the connection to news.php.net timed out.

[PHP] Question about translating assoc. arrays to C

[Joshua Kehn]

I'm working on creating a compiled extension for some code I've written. Mostly 
it's manipulating a very large multi-demensional array of values. This is some 
pseudo code for the array.

// Imagine this but much much bigger
$big_ass_array = array('5' => array('0' => 4, '3' => 6, '8' => 7), '10' => 
array('4' => 3, '5' => 10')); 

Currently I'm traversing this with

foreach($array as $key1 => $value)
{
foreach($value as $key2 => $value)
{
// Use $key1, $key2, and $value here

To expand on this, just a little, once you compile an application, you
have locked it in to a specific CPU, OS and versions of the requisite
dynamic libraries. The compiler options and your tool set define which
range of each of those it will actually run on. The only way to make
something completely independent of the architecture is to distribute it
in source code form. In this case, you are probably better off defining
minimum versions for the web server and PHP module that is required and
allow the user to install those on his own. Most distributions already
have those components packaged in an easy to manage kit.

You can't compile to be architecture independent. The best you can do is
convert a language to a byte-code, like java.

It's not a PHP problem. If you compile something, it's compiled to the
same architecture that you specify, which by default is yours. have you
tried compiling your executable with the same setup as you're currently
using?

Hi, I recently compiled a portable portable web server for linux, using

But it seems that php can only run on machine with the same glibc version

@Tim, You'll have to migrate the stored procedures (SP) from MSSQL to MySQL 
(aka stored programs).  Each DBMS have their own way of implementing the SP.

A basic approach would be to use two tables - one to store the nodes
and second table to store the edges between the nodes. As far as
traversing the graph, the best approach I have seen expands this a bit
to store the full transitive closure of the graph, rather than just
the direct edges:

http://www.codeproject.com/KB/database/Modeling_DAGs_on_SQL_DBs.aspx

It is written for SQL Server, but the idea works OK (and I
successfully tested it once) in MySQL. (I imagine the same would be
true for PostgreSQL.)

The idea is to store the transitive closure (every possible path) of
the entire graph. For instance, if you have a basic graph

A -> B -> C -> D

it stores these paths:

A -> B
B -> C
C -> D
A -> C
B -> D
A -> D

The obvious downside is that edge table can get incredibly large
depending on the nature of the graph you are modeling. (The article
provides much more detail.) I did, however, import a good chunk of an
Active Directory tree (just users and groups, not the full list of
attributes) into this pattern just to test the concept, and I found
that in that case the size of the transitive closure table did not get
out of hand.

I cannot be the only one that is having this problem, what are you using for

[Gary]

The last few times I have posted to the board, I recieved an email, which 
has the subject line of  ??? ??? and is written in what appears to 
be greek, then english then seemingly some arabic language.  It tells me 
that it has recieved an email from me that it suspects is spam and it has 
held until I confirm the e-mail (which I DO NOT), then my post appears on 
the board. I dont open the email, I view it (if there is a difference) in 
outlook express.

I dont want to post the email address or content, but it does not reference 
the php.net board.

Anyone else have this happen?

There is a project dealing with creating a secure login for a web
site. It is being developed multi-lingually and across multiple
languages (PHP, VB.net, etc.).

Forgot 1 more thing, if you really want to be strict about security, you can
set a very highly secured permanent cookie on the user's system on the first
initial login.   You can send them a confirmation code, that it's really who
they say they are, to the email address.  Then the user will need to submit
that confirmation code along with the current password as part of the
initial logon process.  So if a hijacker or eaves dropper try to logon with
your user's info on another system, a new confirmation code would be sent to
your user's email address.  Your user would then know their identity has be
stolen.  Setting this up will entail slight modification to your app and DB
design but will have better overall security.  Again, evaluate your needs
and services ;)

James,

1) Set an encrypted (to prevent hijacking and eavesdropping) cookie to
expire when browser closes
2) Have a table in the DB backend to keep track if the user is logged in or
not and when was the last time the validated user access your site (this
gets updated when the user visit a link on your site by checking the cookie
and the DB entry of the session ID)
3) Set your session timeout accordingly to you security requirement
4) Have a javascript on a timeout to self-logoff should the user is AFK
longer than your session timeout.

If another user or if the same user tries to login with a different browser,
you can check the status of the user.  If the user is logged in, you can
deny it after the authentication.  Should the user closes the browser
without having to logoff, you can check when was the last time the user
accessed your site and see if it's been longer than your session timeout.
For security purposes, you can optionally send a courtesy email notifying
that the user didn't logout properly since last accessed.  This way, you can
track whether if the user's system is compromised in some way or not.  It
all depends on what kind of application, service, user level access, and the
strict security you require.

Tommy

of locking mechanism to make sure that the same user can't login again
somewhere else until first logging off.  What's a good way to achieve
this?  I want to be able to handle situations in which the user closes
their browser without first logging off, where I would want to count
that as a logout.

Perhaps I could do some kind of periodic polling in Javascript, combined
with a query to the database that sets a value when the user logs in and
when the user logs out?  I'm just looking for some conceptual ideas. 
Thanks everyone!

James

 I know the feeling. I will say this, though. I have yet to figure
out, from your URLs, how your site(s) is/are organized. Maybe a reorg

Paul:

Unfortunately, I really don't follow an organization plan for my 
demos on any of my sites (well over a dozen now).


Please understand that when I started creating demos, I only wanted 
to see how a specific thing worked. I had no idea that this 
investigation would become a giant listing of stuff.


I could explain how I can easily create demos if you want, but it's 
pretty basic stuff using includes for a common header/footer files 
leaving only the specific of the topic to be added. The hard part is 
just finding a layout that you like -- after that it's pretty easy to 
duplicate it each time you want to demo something.


I will be updating my sperling.com soon to add in language specific 
code (php/css/js) -- and that *will* be organized into categories. 
However, that may be down the road because I have a few other 
pressing matters that are pulling me in several different directions.


Cheers,

tedd

Looks like you and I are in the same boat! My memory these days has went to 
the dumps.

Although I do the same thing Paul does to actually grasp a more in depth 
understanding of something, sometimes in a day or two it's often forgotten.

ISTR there are three signs of old age. The first is loss of memory, but
I can never remember the other two.

This is Tedd's modus operandi. His website(s) are full of exactly this
type of thing. And I have to agree. I can't count the number of
questions I *haven't* asked on this list, because I built a page to test
a particular concept. And this sort of activity (as opposed to just

All,

I tried and tested it but wanted a solid confirmation on it. I felt foreach
usage is better than manual way of next(), prev() et al.

Thanks for the comments. I consider the thread answered and solved unless
someone has anything more to add.

This is Tedd's modus operandi. His website(s) are full of exactly this
type of thing. And I have to agree. I can't count the number of
questions I *haven't* asked on this list, because I built a page to test
a particular concept. And this sort of activity (as opposed to just

Shreyas:

This is one of those questions that you can test very easily, just 
initialize an array and try it.


");
   }

?>

As the references show, there are two versions of the "foreach", the 
one above and this:


 $value)
   {
   echo("$key= $key  value=$value ");
   }

?>

Note that you can pull-out the index (i.e., $key) as well as the 
value (i.e., $value) of each index. The "" is only to add a 
linefeed in html.


This is a bit easier than using a for() loop.

Cheers,

tedd

An easy way to think about it: foreach is cocky and doesn't give a
damn about the rules array functions or placements have set in place.
It'll start from the beginning, and to hell with everyone else.

In other words: foreach will iterate wholly; it will count *for*
*each* key in the loop, not just where another portion of the code
left off.

Here is your best reference:

http://php.net/foreach

Look at the two Notes sections on the top of the page.

The first says this:

Note: When foreach first starts executing, the internal array pointer is 
automatically reset to the first element of the array. This means that 
you do not need to call reset()  before a foreach  loop.


Basically what you said.  But then the second says this

Note: Unless the array is referenced, foreach operates on a copy of the 
specified array and not the array itself. foreach  has some side effects 
on the array pointer. Don't rely on the array pointer during or after 
the foreach without resetting it.
