RE: [PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS
Hi Jamie. Thanks. Good info. I knew something changed somewhere. This works like a charm in IE8..never saw the New Session option under file...me bad !! Greetings. -Original Message- From: Jaime Bozza [mailto:jbo...@mindsites.com] Sent: 20 August 2009 09:49 PM To: Leon du Plessis; 'Floyd Resler' Cc: a...@dotcontent.net; php-general@lists.php.net Subject: RE: [PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS Leon, This is really just a function of the browser. When a session cookie is created, if the browser is setup for a single instance, that's the session cookie it'll use for *any* request to that domain. This functions differently depending on what browser you're using. For example: Firefox - All windows, tabs, etc, under the same profile will use the same session. If you create profiles, you can have different sessions. IE7, IE6 - All tabs or windows opened from clicks will share the same instance/session. Starting IE from the icon will open up a new instance/session. This worked great if you wanted to run two different sessions at the same site/domain. Just start IE up from the icon again and you'd have a new session. IE8 - IE8 model changed, so that all browser windows, tabs, etc., run under the same frame/session, much like Firefox. Clicking the IE icon again now just keeps the same frame and thus the same session. Originally, this sounded like a big problem, but IE8 introduced a new feature - File Menu - New Session. This will open up a new window that will be a separate frame that will not use current session cookies. Here's just one of many links, but gives some helpful hints on the IE side: http://blogs.msdn.com/ie/archive/2009/05/06/session-cookies-sessionstorage-a nd-ie8.aspx And another: http://blogs.msdn.com/askie/archive/2009/05/08/session-management-within-int ernet-explorer-8-0.aspx One of the issues now is that if you close IE, your session does not disappear. In the past (IE7/IE6), your session would disappear if you closed a browser window that you opened yourself, but it *wouldn't* disappear if you closed a browser window that was opened by a click from Outlook or another program. This was a bit inconsistent. I won't argue whether or not their fix was the best way to go, but now it's at least consistent. Note - In Firefox, not even Private Browsing separates the session cookies. If you start Private Browsing (Firefox 3.5), log into a site, then start a new browser window from the icon (that isn't in Private Browsing mode), it shares the session cookies. (Before you ask, I just checked this to be sure.) IE8 InPrivate Mode is a totally separate session, cookies and all. This could possibly be another way for you to run multiple sessions against the same domain. OTOH, multiple InPrivate sessions running at the same time share the same frame, so they share the same session, so it would only be good for a single new session. If you need more, just use File - New Session.

Having a different session start up for each window for tab would be a major pain. Why? People must please try and understand what I mean by NEW. It does not apply to windows/tabs being opened from a link or request. Imho, keeping the session per domain sounds wrong, it does not mean it is. It would have been nice if: Browser/tab one - my login detail container A. Browser/tab two - my admin login container B. (tabs/windows opened from browser one, then inherits container A naturally) (Closing browser one, then destroys container A then naturally only) NOT Domain.com - one session container only. Heck, I am surprised it works that way at all cause it sounds like the domain can then only handle one user a time if arrays are not used or profiles not created on FF no matter where the request come from, but, then I am obviously missing something in this respect as stated. When I have time I will reconstruct this concept again. Thanks anyway guys. I received some helpful advise for future reference. But please..I do not, like many others, want to start a war.

RE: [PHP] SESSIONS lost sometimes
It's not an issue, it's a feature. Thanks Arno...but it is a pain also. If I work with user A in Tab1 (window1), I want to work with user B separately in Tab2. When user in Tab2 logs off, I still want user A to work, and not suddenly have to re-login. Same with bank. If I work with my company account, then my personal account must not become an issue because I am on the same machine and site. I have no issue with using FF and IE to do testing as that takes care of browser compatibility testing at the same time :-), but I think when you start a new session with new values, it should be kept under that window/tab alone. Cookies can take care of more details, but my opinion is data should never be affected across windows/tabs unless the same user is logged in on botheven then I would expect PHP to keep data per session. Maybe it goes beyond being an IE or FF issue..the questiojn is...will PHP allow variables from session A become corrupted when session B is in progress when they should actually be handled seperately?

It'd make sense for things to run this way, I think. After all, I'd find it quite confusing if I log into Google Docs, open a document (by default, it opens in a new tab) and I had to log in yet again to be able to edit it. Yes. I agree. But in this case the Tab being opened is used with the same authentication details either via POST, GET or Cookie variables.

Cheers Arno The key thing is that both tabs (or windows) from the same browser are in the *same* session - they send the *same* PHPID cookie. PHP is essentially stateless - it doesn't care where the request comes from, and ties a session to the PHPID cookie if it gets one. As far as PHP knows, requests from different tabs with the same PHPID cookie are requests from the same place in the same session. To get a different session you need a different instance of the browser - that's the way browsers have been coded to work. It's not too hard with Firefox, since you can set up multiple profiles to have independent Firefox windows on the same screen. -- Peter Ford phone: 01580 89 Developer fax: 01580 893399 Justcroft International Ltd., Staplehurst, Kent -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] SESSIONS lost sometimes
Hi, Just a re-iteration on the problem: Browser 1 has user A details Browser 2 has user B details User B logs off, then user A is suddenly in logged of status also. The method used to destroy the session is: // Unset all of the session variables. $_SESSION = array(); // Finally, destroy the session. session_destroy(); Problem. User's A session is also destroyed. The concern is, that this should not be the case. User A must happily continue to work. So, should PHP destroy the whole browser's session id's variables? My answer is No. User A and user B should have different session ids, if not, then it is wrong. A new window should have PHP to spawn a new session id (that is, the request does not come from an existing page where an id has been created already. If the ids are different, then session_destroy should only clear variables for relevant session_id, ie only User B's details In this example. The problem then probably lies in the session_ids being either the same for the two different logins (although they are on different browser) or session_destroy clearing data across sessions. (I will test that later). It would then seem that session ids is setup per location/machine by MS Windows as per Peter's explanation. Setting up profiles is the the resolution as suggested. Otherwise, it would be nice if Windows/IE/FF/PHP could identify when a BRAND NEW page is being opened and then create a brand new session id for that window/tab. It is not a huge issue, I was just wondering if someone else had the same annoying condition. I am happy with the responses and the functionality somewhere on a wish-list. Now Back to Angelo's SESSION problem which sounded like it could be related. Greetings!

[PHP] SESSION VARIABLES ACROSS DIFFERENT WINDOWS/TABS
It is just strange that I have this condition now...maybe I missed it a year ago ? Having a different session start up for each window for tab would be a major pain. Why? People must please try and understand what I mean by NEW. It does not apply to windows/tabs being opened from a link or request. Imho, keeping the session per domain sounds wrong, it does not mean it is. It would have been nice if: Browser/tab one - my login detail container A. Browser/tab two - my admin login container B. (tabs/windows opened from browser one, then inherits container A naturally) (Closing browser one, then destroys container A then naturally only) NOT Domain.com - one session container only. Heck, I am surprised it works that way at all cause it sounds like the domain can then only handle one user a time if arrays are not used or profiles not created on FF no matter where the request come from, but, then I am obviously missing something in this respect as stated. When I have time I will reconstruct this concept again. Thanks anyway guys. I received some helpful advise for future reference. But please..I do not, like many others, want to start a war. I am ok with things how they are. We can put this thing to rest. -Original Message- From: Floyd Resler [mailto:fres...@adex-intl.com] Sent: 20 August 2009 02:25 PM To: Leon du Plessis Cc: a...@dotcontent.net; php-general@lists.php.net Subject: Re: [PHP] SESSIONS lost sometimes Leon, Sessions are used on a per-domain basis.

If I work with my company account, then my personal account must not become an issue because I am on the same machine and site. I have no issue with using FF and IE to do testing as that takes care of browser compatibility testing at the same time :-), but I think when you start a new session with new values, it should be kept under that window/tab alone. Cookies can take care of more details, but my opinion is data should never be affected across windows/tabs unless the same user is logged in on botheven then I would expect PHP to keep data per session. Maybe it goes beyond being an IE or FF issue..the questiojn is...will PHP allow variables from session A become corrupted when session B is in progress when they should actually be handled seperately?

Hi PJ,
Maybe you should post your code, or portion thereof. The trained eyes on the
list will quickly gather where the problem in the logic lies.
Maybe you can also sacrifice some of your data or data structures if not too
sensitive. This will help to validate the route you are trying to follow.

Have you heard of while()? You can use it in combination with
array_pop() and count()
like:
?
while (($data = array_pop($array)) !== NULL) {
/* having $data and count($array) changes with every loop */
}

RE: [PHP] what to use instead of foreach
Hi PJ,
Ok, If I understand correctly you can attempt to alter your code as per
following example (I am breaking it down a little for readability):
a) If you only wish to output the authors, see also Mark Kelly's example,
You can simply output as many authors you have associated (you will need an
associated array!!:
Or b) I include the following alternative example:
$string_out = :
Foreach ($my_titles as $titles)
{
Echo Title: $titles By:br;
Foreach($my_authors[$title] as $author)
$string_out .= $author, ; /* Building string */
// Add br
$string_out .= br;
// Here you would replace your last comma with the you want
// There are a few ways to do this (like Mark Kelly's), but will try
// another way (older, maybe less complicated?).
$final_string = substr($string_out,0,strrpos($string_out,,) - 1);
$final_string .=.
substr($string_out,strrpos($string_out,,) + 1);
}
So all you need is to modal your data around this, and you should be fine.
You could construct your arrays then as follows as an example:
$my_titles = array(title1,title2);
$my_authors[title1] = array(a someone,a notherone);
$my_authors[title2] = array(mr. a,mr. b);
...
and so forth...how you construct the data is then very important as you can
then later use it simplify your coding as you progress and as demonstrated
below:
In future, where the need justifies it, you can construct your array to
already contain the needed string you want to output, it may help, but you
will sometimes have the same effort in constructing the data for the arrays,
so it is up to you to decide which approach is going to be best: e.g.
$my_titles = array(title1,title2);
$my_authors[title1] = array(a someone, a notherone Mr. X);
Then you can simply echo the array value:
echo $my_authors[title1] . br;
Hope it is enough info for to work on for now!!
Have fun!

Hey Todd, Eric,
Thanks for replying.
I don't believe you need both the / and the # for delimiters in your
RegEx. Try using just # (since / is actually going to be in the text
you're searching for) like this:
?php
$data =
file_get_contents(http://www.youtube.com/watch?v=oQ2dKXGAjNg;);
preg_match('#title([^]*)/title#iU', $data, $match);
$title = $match[1];
echo $title;
?
You can also escape the / like \/.
Ok, I changed it to:
?php
$data = file_get_contents(http://www.youtube.com/watch?v=oQ2dKXGAjNg;);
preg_match('/#title([^]*)\/title#iU',$data,$match);
$title=$match[1];
echo $title;
?
And this is the error i am getting:
Warning: preg_match() [function.preg-match]: No ending delimiter '/' found
in C:\wamp\www\ezee\tests\get_remote_title.php on line 3
Sorry forgot to include the list in my post to you
Here is another solution if you don't want to play around too much with
regex:
?php
$data = file_get_contents(http://www.youtube.com/watch?v=oQ2dKXGAjNg;);
$strt = strpos($data,title)+7;
$end = strpos($data,/title);
$len = $end - $strt;
$title= substr($data,$strt,$len);
echo $title
?
Produces:
YouTube - REALLY funny ad
As mentioned, you can probably neaten this up a bitregex may be too
complex for the simple requirement needed ?
But for fun, it will be nice to see get if preg_match can do it at some
stage :-)

RE: [PHP] Adding encryption to passwords
You can try the MySQL built in functions. Ie encode(str, key) insert into test (password) values (encode(mypass,some key)); You can then use the decode() functions in your matching queries. You also need to consider security of your php code, as the key to decode will be in the query strings. There are other built-in encryptions functions in MySQL you can explore. -Original Message- From: Thodoris [mailto:[EMAIL PROTECTED] Sent: 19 September 2008 10:25 AM To: PHP General list Subject: [PHP] Adding encryption to passwords Hi guys I have developed an intranet web interface with user access.

[PHP] hash_hmac: Encoding with two different results problem
hi,
I hope this is the right group for this type of problem:
I am using hash_hmac to provide me with a sha1 encoded hash string. The
problem is as follows:
$hash = hash_hmac('sha1',
'030B6A05696E657400C54601C60001550187360603773500018707060373796E63000187340603687474703A2F2F772E73796E632E636F6D2F73796E630001C65901873A06032E2F636F6E7461637473000187070603436F6E74616374732044420001872E0603746578742F782D7663617264000101C6570187310603757365726E616D6500018732060370617373776F72640001010101',
'1234');
Note: it is important the key to use during encoding id 1234 for this
example.
Result:
eb38ffd597c6d1e01cd24a0e46dff426354510fe
Using a hash calculator from slavasoft also yields this result, which
indicate the encoding is fine.
eb38ffd597c6d1e01cd24a0e46dff426354510fe
However, Slavasoft's calculator has an option to provide the string as Text
or Hex.
Selecting hex yields this result:
9f9be99ea5bf5ba009af0a5c12021f420cb27652 and this is the string I
need!!!
So either hash_hmac function needs a way to let it know the string is of
type hexor the string itself needs to be converted. I have tried some
conversions on the string but to no avail.
Anyone have any thoughts?

Just a quick note; why dont' you search on user since it's the constant
and replace 'user[A-Z]' with 'user_[a-z]' or in the case of userID
'user[A-Z]{2}'
This is part of my problem user will not always be constant, I basically want
to be able to change between two naming conventions.
Example:
userID becomes user_id
clientID becomes client_id
tableName becomes table_name
anotherTableName becomes another_table_name

Re: [PHP] html_entity_decode () for hellip;, rsquo;, etc.
Hi Marco
To awnser you question I do not know why it is excluded from the default
decode array. Maybe it could be that these are multibyte characters (any
takers)?
You can get a list of the entities that are changed
$trans = get_html_translation_table(HTML_ENTITIES);
echopre;print_r($trans);echo/pre;
to add some extras as you have below, use something similar to
function htmldecode($string)
{
$trans = get_html_translation_table(HTML_ENTITIES);
$trans[chr(0xe2).chr(0x80).chr(0xa6)] = 'hellip;';
$trans = array_flip($trans);
return strtr($string, $trans);
}
$string = hellip;amp;;
echo htmldecode($string) .\n;
Note: obviously hex e2 80 a6 make up the hellip chars.
Hope this helps
Cheers

Re: [PHP] ampersands in href's
The simplest way to make sure everything work well regardless of what the
values are:
?
$url = somepage.php?var1=.urlencode($var1).var2=.urlencode($var2);
echo a href=\.htmlspecialchars($url).\;
?
htmlspecialchars() changes characters '', '', ''', '', '' into the HTML
equivilant. And yup, you should do this for all *ML pages as long as the
thing being printed is not part of the mark-up syntax.

Alternatively you could $r = (int)$r;

Re: [PHP] Forms on PHP
Refer to the following line numbers:
01 ?php
02 // Start of PHP code - Extract values from form.
03 /* Other values read */
04 $n=$_POST['n'];
05
06 // Pass the data from the form to lightcurve_csharp
07 $command=./lightcurve_csharp $a $i $e $lomega $bomega $lambda $n;
08 $result=`$command`;
09
10 $form_submitted=$_POST['form_sumbitted'];
11 if (isset($form_submitted)) {
12 if ($form_submitted) {
13 echo 'The form has been submittedbr';
14 unset($form_submitted);
15 }
16 } else
17 echo 'The form has not been submittedbr';
When the user first load the page, no data was posted. So there was no
$_POST['form_sumbitted'] available. Line 10 will cause $form_submitted to
contain the NULL value (I think). $form_submitted will evaluate to FALSE at
line 12. Thus it will not display any message.
By the way, by doing line 10, $form_submitted would have been set regardless
whether there is $_POST['form_sumbitted'], and line 11 will evaluate to TRUE
always. Thus you will never ever see the 'form not been submitted' message.
Anyway, when you posted for the first time, $_POST['form_sumbitted'] is
available. The 'The form has been submittedbr' message will be printed.
After that, when you press Reload button on the browser, the post data will
once again be sent from the user. (This is the behaviour of reloading a
posted page. In Internet Explorer there should be a message dialog box
asking the user whether to resend form data in order to refresh.) Reposting
the data during the reload means that there will be
$_POST['form_sumbitted'], thus once again the 'form hass been submitted'
message.
In order to prevent this from happening, you should do a header('Location:
success-page.php') on a successful submit. This is so that at the redirected
page, the user would not have resent data even if he press the Reload
button.
Hope this helps

Subject: [PHP] PHP form POST question
I just narrowed something down about forms and POST and would like
education. In the following scenarios, all work except #4. $_POST is null.
Why is that?
Setup:
1) Running on localhost
2) /foo/index.php has the following:
? var_dump($_POST); var_dump($_GET); ?
3) /index.php contends vary per scenario (below)
Running RHEL 3, all updates (PHP 4.3.2).
SCENARIO 1:
/index.php contains the following:
form method=get action=/foo/index.php
input name=foobutton type=submit
/form
In this case in /foo/index.php $_GET has the right value, i.e.
array('foobutton' = '');
SCENARIO 2:
/index.php contains the following:
form method=get action=/foo
input name=foobutton type=submit
/form
In this case in /foo/index.php $_GET has the right value, i.e.
array('foobutton' = '');
SCENARIO 3:
/index.php contains the following:
form method=post action=/foo/index.php
input name=foobutton type=submit
/form
In this case in /foo/index.php $_POST has the right value, i.e.

SCENARIO 4:
/index.php contains the following:
form method=post action=/foo
input name=foobutton type=submit
/form
In this case in /foo/index.php $_POST is NULL.
HUH? Why is $_POST empty? Is Apache doing something to kill the form's
post information when it has to resolve /foo to /foo/index.php?

[PHP] Creating my own External Module for PHP
Hello, I have a little question to which I hope to find an anwser in here. Currently, I have a big script which receives approx 1.5 million hits every day. Since this script does some common calculations that underlying scripts use, I want to rewrite this into C and initially make it an external module for beta testing and then eventually compile it directly into PHP. Now, I got this really good book, Web Application Development with PHP by Ratschiller and Gerken. It has a complete chapter devoted to hacking the core of PHP which shows how to create extensions. Now, they describe 2 common ways of hacking the core... making a shared object (which is what I want at this point) , or compiling the extension right into the core. They decribe how to make your extension with ~/ext/ext_skel , but they don't describe which steps to take when you only want to make a shared object... the only thing they say is at this point, you should have a new PHP binary or a .so file ... but they never gave any indication how to chose... they just asume you want a new php binary or sth.

I have examined DBG and it's the one that fits my needs better, but there's not too much information on how to use it and what I have found is not complete.

Thank you ,Jimmy . -ÔʼÓʼþ- ·¢¼þÈË: Jimmy [mailto:[EMAIL PROTECTED]] ·¢ËÍʱ¼ä: 07 January, 2002 12:13 ÊÕ¼þÈË: [EMAIL PROTECTED] Ö÷Ìâ: Re: [PHP] How to read/write form/into certain place in a text file Hi Leon, For example,read form letter 5 to 10 in line 4 ,and after some procedure ,write into the same place. if the file is not too big, you can use file() function which will return an array containing the content of the file per line. combine this with substr() to read from specific column. to write use substr_replace(). if the file is big, then doing file() is not advised, you should read the file as stream. read the following functions: fopen(), fclose(), fseek(), fread(), fwrite(). Another question is that if a user has opened the file to read and write , what will happen if another one will open and write the same file? php doesnt handle file locking automatically, so i think it would depend on the OS. if you want to handle file locking, read about flock(). -- Jimmy God is greater than your greatest problem -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] Regular expression question
Hello, I have a little question regarding regular expressions... I want to check for the pattern $num:: But, $num may not be started with another number (assume the number will be 51 , 1 will also match (the pattern 1:: is available in 51::) ... Currently, my regular expression is: eregi(([^0-9]$num::), $string); But that doesn't seem to work... The other option, the start of a line or a : also didn't work: eregi(([^|:]$sess_id::), $string); Anyone can help me with this?

[PHP] Regex problem
Hi there, I am camping with a little regular expressions problem... Problem: I want to check if $variable begins with a * (star), and it doesn't matter if it starts with plenty of spaces... My solution: ereg(^[:space:]*\*,$variable) But, it doesn't seem to work with the space part... The regex: ereg(^\*,$variable) does work, but that doesn't include spaces at the start... How can I extend this one so that it doesn't matter if there are a lot of spaces at the begin? Thanks in advance, Leon Mergen
[PHP] HTML in XML???
Hi, Is there some way to include HTML tags in a XML doc??? I want to use a XML document to include HTML data for my webpage. I have made a solution of replacing a special word to the '' and ' of a HTML tag. But I think my solution is very stupid. And is there a special php xml newsgroup?? thanks, Leon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Re: [PHP] Site Searchable function
On 19 Apr 2001 13:25:09 -0700 impersonator of [EMAIL PROTECTED] ("Steve
Lawson") planted I saw in php.general:
fopen("http://localhost/name-of-file") will return the rendered page instead
Sounds good (theoretically:). Hovever, in practical attempt on my remote
server it gave:
Warning: fopen("http://my.domain/file_name.htm","r") - A socket must be
already connected. in ...etc on line 304
where it worked ok with 'filesystem open' (On my home window localhost, it
worked though). Suggestions, how to go around this problem?
Leon.
