Try this snippet



http://www.csszengarden.com//001/001.css";, "r");
$data = fread($css, 3);
preg_match_all("/#.+({ )/", $data, $out);
print_r($out);
?>


It gets the default css from the zengarden site. (30k is a large
buffer, but this is not a howto on buffered reads)

The regular expression 

/#.+({ )/

means, piece by piece


#  the # character
.  dot is a special character in regular expressions. it can match
any character
+  is also a special character,  it means match 1 or more times

so .+ means match any character 1 or more times

( ) are special characters, they match any single character inside them.

in the case of ({ )  , it matches either a space or a left bracket

So, the whole expression means:

match a strings where they start with #, followed by 1 or more
characters, followed by a space or a left-bracket

Note that these are very simplified explanations for regular expressions. 

Now, try the expression

/#(.+)({ )/

and instead of  print_r($out), try

print_r($out[1]);


Now you get the classnames :)  Check out the following sites for more
info (they appear first when you google regular expressions).

http://sitescooper.org/tao_regexps.html
http://etext.lib.virginia.edu/helpsheets/regex.html


Also, check out the PHP manual for the preg_* functions

---
Note that the script i gave you has problems with classnames on one line, like

#footer a:link, #footer a:visited 

But I won't spoon feed you :)

So, maybe someone knows good blog hosting scripts

[PHP] session cookie paths

[Ian Firla]

Dear All,

I've been trying to figure out a solution for this problem and have
googled the subject but cannot come up with anything meaningful.

I have several applications running on my server which use php and
sessions.

In each case, logging out from an application destroys the session.

The trouble is that all the applications (four of them) share the same
id: PHPSESSID and path: /

My first hunch is to try to use .htaccess in each application's root
directory to override these php.ini variables. Am I on the right track?

Regards,

Ian

[PHP] Destroying a Session

[Shaun]

Hi,

I am writing a shopping cart and am using a session called
$_SESSION["orderinfo"] to store the order information. I also have a
function I use to clear the session when the payment has been authorized:

function clear_orderinfo() {
  global $_SESSION;
  unset($_SESSION["orderinfo"]);
 }

However this function doesnt seem to work and the session remains active, is
there another way to clear a session?

Thanks for your help

You do have a session_start() somewhere, right? Also, $_SESSION, like
$_GET, $_POST et. al. are automatically global, you don't need to
specify global $_SESSION.

I'm not triffically experienced, but I do have notes on the subject.
You're wanting to clear the whole session, right?

$_SESSION=array();
session_destroy();

For specific variables, try assigning FALSE to it
($_SESSION['name']=FALSE; or 'unset' works for versions >=4.2.2. Otherwise
use session_unregister. For me under 4.1.2 I had to set to null.

You can do this from within PHP by calling session_name() before 
session_start, also.

You could also use set_cookie_params() in each of the scripts.

A search using the keywords "browser" and "javascript" would have
shown you the PHP function get_browser()

http://www.php.net/manual/en/function.get-browser.php
 
and notes in the page will point you to the more full featured
javascript detection script:

[PHP] Odd behaviour of non-existent keys?

[Geoff Caplan]

Hi folks,

Getting a result I don't understand.

Why does the non-existent key in the array below evaluate to the
first char of the array value?

$foo = '' ;
$foo['one']['two'] = 'test-value' ;

// Evaluates to: string(1) "t"
var_dump( $foo['one']['two']['three'] ) ;


// Evaluates to NULL, as expected
var_dump($foo['one']['two']['three']['four'] ) ;

Can anyone enlighten me?

I spotted this because I was getting unexpected results with isset()
used on multi-dimensional arrays.

I'm using the latest version of PHP4 on Debian.

Strings are arrays. PHP probably takes the string 'three' and converts it to 
a integer to see what "key" of the string you're requesting.

$foo = 'bar';
echo $foo[1]; //should echo 'a'
Does that help or do you need a deeper explanation (that I probably can't 
provide!) ;)

I think you are probably right - but this behaviour causes problems.
For example:

$foo['one']['two'] = "test-string" ;

// Evaluates to TRUE (not what's wanted!)
isset( $foo['one']['two']['three'] ) ;

I need a reliable way to test for the non-existence of a
multi-dimensional key. Any ideas? I guess I could convert the keys
into a string via a loop and compare that, but there must be a more
elegant way, surely?

How about array_key_exists?

array_key_exists('three', $foo['one']['two']);

Re: [PHP] Sessions vs. IE security

[Stanislav Kuhn]

Thanks guys for helps.. I've tried many that things and I found solution.
Solution for me was set up Privacy Policy for our site...
First time it didn't work because i haven't done Compact privacy policy
witch is optional but IE requires it ;o)

While compact policies are entirely optional for P3P-enabled web sites, IE6
relies heavily on them. This browser makes cookie-blocking decisions based
solely on compact policies. By default, IE6 blocks "third-party" cookies
that do not have compact policies.

But anyway I passed page trought w3c validator and with good settings of
privacy policy IE now allows every (inc. third party) cookies in all levels
of security (except level block all cookies of course). And it means i can
use sessions without problems.. And I recommand  to do same as soon as
possible for everyone. Microsoft going to be crazy in security. Today that
are third-party cookies tomorow may be first_party!...

IMHO what you have described is a bug in PHP, and if I were you, I'd report it as
such.  If it's not a bug it at least has a very high WTF factor.  Having to use the
cumbersome:

is_array($foo['one']['two']) && array_key_exists('three', $foo['one']['two'])

instead of:

isset($foo['one']['two']['three'])

seems kinda silly to me.  I doubt that this is the intended behavior.

How did you install php?  RPM (or similiar package), or source?
If you installed from RPM, you can add the php-mysql rpm, and restart

If you're on a RPM based system (Red Hat, Fedora, etc), do this at the

rpm -qa | grep php

Look at the output of phpinfo(). But before doing that, read the
documentation or you'll be back here in a flash with more really basic
questions.

A very good source for answers is also php.net. Try typing in some of
your problem terms like "mysql" into the search query.

The pid i need to kill is the one from the line:

squid 9283  0.0  1.0  8392 5060 ?S16:04   0:00 (squid) -D

How can i get this pid so i can kill -9 it and then start squid again ?

Start here http://www.php.net/exec
To get the PID you may be able to place the output of ps -aux in an array, regex for 
what you want, then exec

[PHP] PHP Login Script

[Chuck]

Could anyone let me know or point me to where I could find out how to setup
a login for my php site.  I've been looking around and found plenty of stuff
for PHP/Apache, but nothing for just PHP.

Any help or info about this would be appreciated.

Hi,

Thank you for your replies. I am using version 4.3.3 yet unset() doesn't
seem to work. To test this I have placed this line of code in my footer.php
file that appears at the bottom of every page:

echo 'load_orderinfo() = '.load_orderinfo();

Here is the load_orderinfo() function:

function load_orderinfo() {
  global $_SESSION;
  if (empty($_SESSION["orderinfo"])) {
   return false;
  } else {
   return $_SESSION["orderinfo"];
  }
 }

Before the $_SESSION["orderinfo"] is created the output in the footer reads:

load_orderinfo() =

When it has been created it reads:

load_orderinfo() = Object;

On the complete_order.php page where I call the clear_orderinfo() function
it goes back to:

load_orderinfo() =

but it on any subsequent page the output returns to:

load_orderinfo() = Object;

But after calling the clear_orderinfo() function surely the
$_SESSION["orderinfo"] should have been destroyed. I hope this makes sense!

Thanks for your help

You need to store user information somewhere and apache .htpasswd files 
and mysql databases are popular choices.

If you are talking about acessing the outlook calendar on a client

If you are talking about outlook web access with exchange yes you can 
connect to the exchange server but how to do it you will have to ask in 
a microsoft support group.

Did you try Google? It turned this up ...

The trick, I think, would be knowing the schema of the .pst. In early 
versions you could use Access to open the .pst.

Hi,

remove the global $_SESSION; lines in your functions - they are uneccessary.
Have you tried resetting $_SESSION instead of unset()?:

$_SESSION = array();

Hi Chuck,

you could try those two PEAR packages:
http://pear.php.net/package/Auth
http://pear.php.net/package/LiveUser

If you have any questions about those packages that the docs and the source
code can't answer there is the PEAR general mailing list to help ;)

the get_browser function return me a value that simply means that the

has enabled it in the browser.
So set a form/URL variable with JavaScript and see if your PHP page receives 
it. Hidden  would probably work, or image, etc... You'll need a page 
refresh or redirect in between though to detect it.

Shaun,

For what its worth, I experienced probs with destroying sessions until I added 
another page. On the page in question, I called the 'logout' function and 
redirected to that page:

[logout.php]
http://your_site.back_to_page_that_is not_logged in.php");
?>

Note that I used an absolute url -- it seems to make a difference. [Btw, I 
note that you use double quotes for $_SESSION['orderinfo'] -- just wondering 
. . . .

HTh,
Andre

And as this this type of question gets asked every other day searching the

various ways to:

- enable mysql functions in Windows systems
- recompile PHP include support for mysql functions
- install the relevant RPM package for RPM based systems

[PHP] change for exec function and safe_mode between win32 command line interface php 4.3.4 -> php 4.3.7 ?

[Daniel Gaddis]

We upgraded from win32 php 4.3.4 to 4.3.7 and my php command line script
broke. 

I am using safe_mode=on. If I use safe_mode=off instead of safe_mode=on
it works. Why
would my php command line script work with win32 php 4.3.4 with
safe_mode=on but not
with 4.3.7?

For a test I created a file f:\batfiles\batch\today.bat that contains
the following line:
date /t

I can then run the following command to test:
php -c F:\batfiles\batch\php.ini -r
print_r(exec('f:\batfiles\batch\today.bat'));

with win32 php 4.3.7 with safe_mode=on  I get nothing
with win32 php 4.3.7 with safe_mode=off I get Wed 08/25/2004

with win32 php 4.3.4 with safe_mode=on  I get Wed 08/25/2004
with win32 php 4.3.4 with safe_mode=off I get Wed 08/25/2004

In case you are wondering php.ini also contains:

safe_mode_exec_dir = f:\batfiles\batch
open_basedir = f:\batfiles\batch

Any suggestions?

Thanks,
Daniel

[PHP] summarized results

[Erik Meyer]

I have a function loosely based on the following tutorial from zend.com.
(http://www.zend.com/zend/tut/tutorial-brogdon2.php)
However, instead of using plain-text I am using results with html tags.

 For example, the results may have Thisis some text that has been
inputted from a form.  When I use my function it simply takes this string
and counts  the number of words and then stops at a length desired and
returns the text.  Now, here is my problem.  If I don't call my function it
displays fine, but I have to display the entire result since I do not want
to stop in the middle of a word.  If I call my function it displays the
summary correctly if there are no html tags in it.  However, if I call my
function and there are html tags then it strips the < > off of the html tag
and displays the text in between the angle brackets.

Here is my function (forgive me if I am taking the wrong way this is my baby
step at php)

If anybody has a better way I would appreciate it,

Thank you,

Erik  Meyer

The code is:

$results = mysql_query($q);
if ($results) {
while ($list=mysql_fetch_assoc($results)) {
$things[]=$list;

//$things[7] is a MySQL timestamp column named "last_login"
$date = strtotime($things[7]);
You're creating a two dimensional array. $things[0][7] is the first row, 
eight column, which is what you're after if this only returns one row.

if you want to use $things[7], then within your while loop, use $things = 
$list;, for example. Although, if you're only getting one row, there's no 
need for a while loop and you can just say $things = 
mysql_fetch_assoc($results);

Oh, one more thing. fetch_assoc() returns an array with the keys named after 
the columns, not as numbers. So $things[0]['last_login'] or 
$things['last_login'] is what you're after. Or use mysql_fetch_row(), which 
will return keys as number... or use mysql_fetch_array(), which will do 
both.

have fun. Don't break anything.

You are right - it does seem like a bug. But I assumed that something

Re: [PHP] Array?

[Craig Brothers]

how many elements are returned by the sql statement?

If you want the 7th item returned in the sql statement would need to
code $things[6]

Just a hunch...

You are fetching an association... use the following instead:

$date = strtotime($things['last_login']);

Subject: [PHP] summarized results


I have a function loosely based on the following tutorial from zend.com.
(http://www.zend.com/zend/tut/tutorial-brogdon2.php)
However, instead of using plain-text I am using results with html tags.

 For example, the results may have Thisis some text that has been
inputted from a form.  When I use my function it simply takes this string
and counts  the number of words and then stops at a length desired and
returns the text.  Now, here is my problem.  If I don't call my function it
displays fine, but I have to display the entire result since I do not want
to stop in the middle of a word.  If I call my function it displays the
summary correctly if there are no html tags in it.  However, if I call my
function and there are html tags then it strips the < > off of the html tag
and displays the text in between the angle brackets.

Here is my function (forgive me if I am taking the wrong way this is my baby
step at php)

If anybody has a better way I would appreciate it,

Thank you,

Erik  Meyer

$things[7] is actually an associative array containing the seventh result
row from your query. If you check out the results of print_r($things),
you'd see the array structure immediately.

i have to check if it´s inside frames, pass values for only one a respective

maybe next time the project can be better planned, but i can´t see how at

Anything can be used, I was using that as an example.  The information in

[PHP] Caching Database Information

[Paul Higgins]

Hello all,
I have some questions regarding caching information with PHP.  I was 
thinking that I might cache all information that won't be changing for long 
periods of time...possibly only once a day or so, instead of querying the 
database for information every time.  My question is:  is there such as 
thing as too much caching?

Can I cache too much and therefore negate the advantages of caching?
Thanks,
Paul

[PHP] mail functions help

[AceZero2790]

I'm trying to make sure that my mail functons are on for a script I need to 
work. I run an Apache 1.3.31, so I am my own webhost. Now I just need to know 
how to make sure my mailfunctions are on.
Here is the mail functions part of php.ini pertaining to me (the windows part 
because I am on XP):

[mail function]
; For Win32 only.
SMTP = localhost
smtp_port = 25

; For Win32 only.
;sendmail_from = [EMAIL PROTECTED]

There is no reference to sendmail_path and stuff in the windows section, only 
under Unix. I was told that I didn't need it for my particular background, is 
that true?

I've been told stuff about how I need to make sure that my SMTP server 
(whatever that is??) is accepting stuff from localhost, etc, etc. If someone could 
clarify that'd be great.

As long as the overhead in caching remains less than the overhead in not
caching, I would say maybe.  :)

A single database query returns an array.  You use the array to build a
page.  You cache the page.  The cached version of the page gets hit 100
times.  Is the overhead in pulling the file from your cache 100 times
less than re-doing the query 100 times?  That depends.  Some databases
have query caching, and so do most file systems.  There are also PHP
caching tools like TurkeMM Cache and Zend that cache byte code only.

I'd bench it both ways and then decide based on the queries, the
development environment, and the cache timeout limitations/requirements.

If you just want to see if mail() works try it.



If it doesn't work then your mail setup is not working.  Setting up an
SMTP server has nothing to do with PHP.  Google will probably help you
if that's your issue.

I can think of a number of them. 

1) pipe your results through striptags() to remove all HTML formatting
   *before* you shorten the string
2) use a templating engine. Smarty has some incredible functions such as
   truncate() which can not only take care of the HTML formatting but
   also make sure that truncation ends with a word or sentence boundary
3) look at code such as the above-mentioned Smarty to see how others
   have successfully resolved this.

I use (2) with a number of systems, and love it.

My guess is that you may need to think about setting up a mail server
first before you can get mail functions to work. If you don't know what an
SMTP server is, first thing to do is to get to know what it is. You can't
send mail without one.

First thing:
http://www.webopedia.com/TERM/S/SMTP.html

I'm not too familiar with what MTA's are out there for windows that are
free.  All I know is Exchange for windows and I don't think it's free.

[PHP] crypt()

[Aaron Todd]

I have developed a PHP based site that requires users to login.  Their login 
information is kept in a MYSQL database.  Currently, I am using an IF 
statement to verify what the user enters as their password with what is in 
the the database.  If they are the same a session is created and they have 
access to the content of the site.

As far as I know the password is being sent to the script in clear text and 
I was wondering what a good way would be to get this to be encrypted.  My 
first thought is to encrypt the password in the database using crypt().  So 
if I view the table I will see the encrypted characters.  Then change the IF 
statement to encrypt the password that the user enters and then just check 
if its the same as what is in the database.  That sounds like the same as I 
am doing now only instead of checking a password that is a name, its 
checking the encrypted characters of the name.

So it seems my idea would hide the real characters.

Can anyone tell me if this is a bad idea.  And maybe point me toward a good 
one.

Thanks,

Aaron

output would be

$test[0] = 0;

well, you can access strings like arrays already. So instead of 
exploding you can already do something like
$var = "15 is a number";
$var[2] = 7;

echo $var;
// will output: 17 is a number
same way goes for accessing them

Use preg_split(): http://php.net/preg_split - example 2.



Or, a possible faster method, using str_split() (only available in

Well, that would leave a blank entry end of the array:

array(6) {
  [0]=>
  string(1) "0"
  [1]=>
  string(1) "0"
  [2]=>
  string(1) "0"
  [3]=>
  string(1) "0"
  [4]=>
  string(1) "8"
  [5]=>
  string(0) ""
}


Besides, strings containing spaces could also produce unexpected
results (like "foo bar baz"):

array(14) {
  [0]=>
  string(1) "f"
  [1]=>
  string(1) "o"
  [2]=>
  string(1) "o"
  [3]=>
  string(0) ""
  [4]=>
  string(0) ""
  [5]=>
  string(1) "b"
  [6]=>
  string(1) "a"
  [7]=>
  string(1) "r"
  [8]=>
  string(0) ""
  [9]=>
  string(0) ""
  [10]=>
  string(1) "b"
  [11]=>
  string(1) "a"
  [12]=>
  string(1) "z"
  [13]=>
  string(0) ""
}

I would still suggest str_split() if available, otherwise
preg_split().

[PHP] checking for utilities/applications in the PATH

[Chris Wagner]

hi,

i am trying to do a simple check for archiving utilities (zip, unzip,
...), to make sure they exist within the PATH, and are executable by
PHP.

i could not find a better way to do this through php, so i went ahead
and did an

exec('which ' . $utility, $output, $return_value);

then, i check the $return_value for a non-zero value, which would
indicate that the utility was not found.  using GNU/Linux this seems to
work fine, but i wouldn't mind keeping my work cross-platform.

so, my question is, is there a better way to do this?

and, if not, what i have done, for now is the following:

$result = exec('which ' . $utility, $output, $return_val);
return( $result  &&  !$return_val );

from one quick test i ran, i determined that exec() simply returns NULL
or nothing if the given utility/command doesn't exist (`which`, in this
case).

so, i expect the above code to simply return true, or skip the test for
my $utility rather, if the `which` utility is not present on the system.

will this work as expected in all cases/systems?

thanks a lot.

If you don't want to use the shell, you can check the $_SERVER['PATH']
environment variable. On my (linux) system it looks like
"sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin", so you could explode() that
on ':' and then cycle through the files in each directory using readdir(),
checking each with is_executable().

You could also just check the output of your exec() call - it should be
the full path of the executable you're looking for. An empty return would
imply that there isn't a matching executable. I think which always returns
just the first match, since it's meant to show what would get called if
you were to use that command.

Personally I love using exec() to make php behave like bash at times, but
posts on this list from pparently knowledgeable people occasionally imply
that it's not the best/fastest/most stable method to use, so I try not to.

[PHP] open_basedir "/" not working after upgrade

[Federico Petronio]

Hello all...
I just upgrade PHP from version 4.3.4 to version 4.3.8. After the 
upgrade, almost everything worked fine but the open_basedir directive.

The server I administer provides hosting for several domains, all of 
those with its own homedir restricted using open_basedir  in 
a  scope. Some especial directories, for example the 
webmail directory, is there only one, but it is shared by all the 
virtualhosts (http:///webmail/). I achieve that using (en 
httpd.conf):

Alias /webmail "/apache2/htdocs/horde/imp"

   php_admin_flag safe_mode off
   php_admin_value upload_tmp_dir /tmp
   php_admin_value open_basedir "/"

This worked fine until the upgrade. After it, I get a message claiming 
that the open_basedir directive is in use, and that 
"/apache2/htdocs/horde/imp" is not in (/).

I guess this could be an error in the open_basedir implementation (or 
just a change), but I am not sure. What I saw is that in recent version 
there were a lot of "move" around open_basedir code.

Can anybody help me with this? is there any patch I could apply to solve 
this?

Thank you!

[PHP] Looking for a "TODO:" parser.

[Daevid Vincent]

I, like many other people I'm sure, put //TODO: comments in my code (inspite
of M$ patent on the idea!).

http://yro.slashdot.org/article.pl?sid=04/06/08/2319254&tid=155&tid=109&tid=
156&tid=17

I'm looking for a program that will run through a directory tree and parse
all the files (ideally by extension, like *.php, *.js, *.html, *.c) and give
me a formatted output (or HTML table or something useful).

It should include the //TODO of course, the path/file, the line(s), and
perhaps other things I'm overlooking. Maybe last time file changed/file
date, and possibly the comments immediately below the //TODO: (as sometimes
they take up more than a single line).

Anyone know of or have built something like this... That is before I go and
re-invent the wheel.

Not sure about other file types, but phpdoc includes a tag for "todo". It
also makes nice documentation on the fly based on your comments.

Re: [PHP] mail functions help

[enijmax]

Hello Andrew:
SMTP server can be retrieved from your ISP provider. The function of
SMTP server is sending the mail to other SMTP server. For example, if you
want send a e-mail [EMAIL PROTECTED] , the SMTP server A will send this mail to
SMTP server B, and SMTP server B will send to SMTP server C, and so on.
Finally, the mail will send to yahoo.com (it is a SMTP server, too) and wait
for xxx to download the mail.
I hope that the explanation can help you to setup your mail
function.

[PHP] imap_fetch_overview() increases traffic to NFS server

[Kathie Grigg]

Hi,

We have a linux server running a customised webmail application
based on Horde. This server communicates with a seperate NFS server
to access user's email data.

We noticed that the traffic between the servers quickly rose from
under 200k/s to 3Mb/s when we made some modifications and we
found it was due to this function call:

$mailList = imap_fetch_overview($stream, $messages, FT_UID);

When we removed the FT_UID flag from the call the traffic 
returned to normal. I don't understand why this extra flag would
cause such a huge rise in traffic- from what I understand this flag
merely causes UIDs to be returned for the array of messages.

The versions we are using are:
Redhat Enterprise Linux ES Release 3
php 4.3.2-11
php-imap 4.3.2-11
Apache 2.0.46-32

Has anyone else had this problem? Is this a bug or am I doing something
wrong?

Thanks for your help!
Kathie

Take a look at running Squid in httpd accelarator mode as well. Other

You can use regular expressions for this.

$in = 'meep';

preg_match("|>(.*)|", $in, $out);

$foo = $out[1];

print $foo;

...prints: meep

This is just a quick and dirty example of how this can be done.

Is it just that you're lazy and don't want to search the archives for
something which is asked all the time, or just naive enough to think
that the people on this list will do your work for you?

Try one of the following:

1. Search google:
http://groups.google.ca/groups?q=href+group:php.general&start=50&hl=en&lr=&ie=UTF-8&group=php.general&selm=01c1ba53%24dd9c6270%24e2563944%40cc1966780a&rnum=57
2. Search the archives of this mailing list
3. Buy a book
4. If all of the above fail, turn off your confuser/computer and walk
away
