The manual is all you need to know, you just need to experiment with the
information provided until it clicks in.

Okay, simple:

The above stuff didn't really make sense, you havn't explained what you are
trying to do and what does not work.

> Do I only call setcookie if the cookie isn't set, or do i call it every
> time I load the page to initialize it?  Once I set it, how do I read it?

setcookie() does what you would expect, sets a cookie. As explained on the
PHP manual, " setcookie -- Send a cookie "
So, logically, you only need to call it when you want to set a cookie...

If you want to read the contents of the cookie, print_r($_COOKIE); That will
show you all cookie information on their computer for your domain.

If you know the name of the cookie you set, simply print $_COOKIE['name']

There's not a lot to it, all the information you'll need is on the manual,
good luck!

$$varname is turned into $foo, what is the value of $foo?

If you're trying to access "public $foo" then Richard was entirely correct
(sorry richard!), just do it like so: $a->foo

If, like in the below example, $foo is the name of a variable that you want
to access, then try ${$foo}, everynow and then there's a problem to that
effect

Good luck, welcome to oop :)

Good luck, welcome to oop :)

PHP 5 is great ! :D
My favorites are __get() and __set()
It allows a very flexible programmation and a very simple programmation 
when using huge objects correctly implemented.

I tested that and it strips the script tags with "language" too. I
do know that it will not strip script tags that have no attributes:
var yada;... 

This will fix that though:
   /]*?>.*?<\/script>/is

   or
   !]*>.*!/isU

[PHP] Putting a stop in a foreach

[Verdon Vaillancourt]

Hi :)

I'm trying to put a stop in a foreach statement following the user
suggestion here, php.net/manual/en/control-structures.foreach.php

Not really knowing what I am doing, I am running into some synatx problems.
I'm sure I'm doing something really stupid, can anybody point it out?

This is the original statement that works...

foreach ($this->_content as $item) {
if ($item['type'] == 'item'){
$elements['ITEM_LINK'] = $item['link'];
$elements['ITEM_TITLE'] = $item['title'];
$elements["TARGET"] = $this->_target;
$items .= PHPWS_Template::processTemplate($elements,
"phpwsrssfeeds", "block_item.tpl");
}
} 


This is my attempt to count items and put a stop in the foreach so it only
returns 5 items.

foreach ($this->_content as $n => $item) {
if ($n=="5") { 
break;
} else { 
if ($this->_content[$n] => $item['type'] == 'item'){
$elements['ITEM_LINK'] = $this->_content[$n] => $item['link'];
$elements['ITEM_TITLE'] = $this->_content[$n] => $item['title'];
$elements["TARGET"] = $this->_target;
$items .= PHPWS_Template::processTemplate($elements,
"phpwsrssfeeds", "block_item.tpl");
}
}
}

Php doesn't like the syntax on any of the,
$this->_content[$n] => $item['type']
, etc lines


TIA,
Verdon

Why don't you use a for() loop to restrict to 5 loops?:

$count = count($this->_content);
for ($i; $i < 5; $i++) {
...
}

>
> Php doesn't like the syntax on any of the,

Because => is a foreach() specific syntax. As far as I understand you don't
need $this->_content[$n] as this is the same as $item, so just omit
'$this->_content[$n] =>':

 if ($item['type'] == 'item'){
 $elements['ITEM_LINK'] = $item['link'];
 $elements['ITEM_TITLE'] = $item['title'];
 $elements["TARGET"] = $this->_target;
 $items .= PHPWS_Template::processTemplate($elements,
"phpwsrssfeeds", "block_item.tpl");
 }

Please try and report if it helped.

Sorry, I mixed up the for and the foreach syntaxes. Here my (hopefully
correct) loop proposal:

for ($i; $i < 5; $i++) {

 if (is_array($this->_content) && is_array($this->_content[$i]) &&
$this->_content[$i]['type'] == 'item') {
   $elements['ITEM_LINK']  = $this->_content[$i]['link'];
   $elements['ITEM_TITLE'] = $this->_content[$i]['title'];
   $elements['TARGET'] = $this->_target;
   $items .= PHPWS_Template::processTemplate($elements, 'phpwsrssfeeds',
'block_item.tpl');
}
}

$elements and items should be initialized before the loop.

 // do stuff

$i++;
if ($i > 5) break;
}

Re: [PHP] Putting a stop in a foreach

[Verdon Vaillancourt]

Hmm, yes I see. Thank you.

I guess what I should look at then is getting the key value (internal
counter/pointer) in the array going to the foreach. Like this example...

$a = array( 1,2,3,17 );

$i =0;/* for illustrative purposes only */

foreach ( $a as $v ) {
    echo "\$ a[$i ]=> $v. \n ";
   $i ++; 
}

Once I have that key value (internal counter) I should be able to do
something with it? What I really want to do (since I can't easily get at the
query building the array being passed to the foreach) is get the foreach to
stop outputting results at a certain limit.

Thanks again,
Verdon

Hi, all --

I guess I need a primer on cookie usage.  I've read the manual regarding
setcookie and have gone back to look at everything having to do with
cookies on this list in the past few months (it seems that I'm not the
only one with some troubles, but most of them appear to have been having
sent some HTML output before trying to set a cookie).

I want to check to see if the user has my cookie to then log him in
automatically, and if he doesn't then I show the login screen and he logs
in and then I set the cookie if the box is checked.

Of course, $_COOKIE is set, so I have to check for my cookie name.  Even
something as simple as

  $_COOKIE['test'] = 'tested';

followed by a load of the page and a print doesn't show it.

Do I only call setcookie if the cookie isn't set, or do i call it every
time I load the page to initialize it?  Once I set it, how do I read it?
Does anyone have any pointers to a basic tutorial?


TIA & HAND

:-D

Under normal circumstances you don't need to do that (unless you know
what you are doing - but it will not set a cookie on the client side,
it only modifies your superglobal variable for as long as the script
runs. I guess I'm once again stating the obvious).


> followed by a load of the page and a print doesn't show it.

> Do I only call setcookie if the cookie isn't set, or do i call it every
> time I load the page to initialize it?  Once I set it, how do I read it?

Once you setcookie() you can optionally give it something on its way:
like name, value, expire time/date, etc.

You could for example set a cookie to expire in half an hour - i.e.
for a session. It might make sense to refresh that cookie on every
page request, so that a session timeout will be postponed on each
refresh.

If you omit the expire time, it will be valid until the end of the
session (browser closes) - see the docs.


How do you get your cookie back?

If your visitor has a browser that allows cookies and you already sent
him one (or more) before, he will automatically transmit it to you as
part of the HTTP request headers. PHP does its magic and places the
values received into that Superglobal $_COOKIE (as well as $_REQUEST)
for you to play with...

So, if that array is empty that could mean two things:
1) you didn't send any cookie before (either because you already sent
your headers and thus have a f***up in your code or because the
visitor hasn't been to your page before)
2) the visitor does not allow cookies - too bad.


I guess that's all there is to it. Someone correct me or add to that
:)


> Does anyone have any pointers to a basic tutorial?

I didn't use any other page except the obvious one ...

I'm  not sure why  you  changed all this.

All you have to do is a simple foreach loop with a counter, and
break when the counter reaches your condition:

$need = 5; /* how many we want */

foreach($this->_content as $index => $item) {

  if ($item['type'] == 'item') {
//...

/* only decrement if its an 'item' */
$need--;
  }
  if (! $need) break; /* we got everything we needed */
}

You can prevent the average joe from printing by putting some css

@media print { body { display:  none; } }

I wouldn't suggest this method, it is making the assumption that
the indexes are numeric and sequenced from 0..5

Modify your code like this and send it's output.. 

/* or ini_set('error_reporting', E_ALL);  if your version

error_reporting(E_ALL);

$fp = fopen('t.txt', 'r');

if ($fp === false) {
  die('cant open file');
}

always check the result of an fopen. feof() will only work on a
valid file handle.

$fp = false;
while (!feof($fp) ) {
  //infinite loop
}

and you'll never know what hit you if your error_reporting is to
low; ensure that at minimum, E_WARNING is on.

Correct, I forgot =0. But as far as I have seen his indices are numeric.

[PHP] Re: Putting a stop in a foreach - SOLVED

[Verdon Vaillancourt]

Hi Torsten, Aidan and Matt

Both of Torsten's and Aidan's suggestions worked, though the number of
returned results using Aidan's method isn't what I expected. This could be
the result of something else and I'm trying to puzzle out why. Matt helped
clarify my basic misunderstanding in what the foreach statement was doing.

Conceptually though, Torsten's and Aidan's suggestions both work.

[PHP] Clean Open Source PHP extranet app?

[david david]

Hello,

I am looking to create a simple "extranet" type
application similar to http://www.basecamphq.com/
written by 37signals.

Basically I just need a way for users to share
files/projects/messages.  

In fact, I would just go ahead and pay for Basecamp
except that it's closed source and it's only available
as a hosted service. (??!?)

Is there a similar open source application written in
PHP/MySQL?

Googling for such a project just returned a bunch of
PHPnuke/Portal type applications.  Not at all what I
need.

Any ideas?

Thanks,
David

[PHP] Curl & cookies

[Jason Morehouse]

Has anyone tried using curl to fetch a web page and cookies?



$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, 'http://www.php.net');
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEJAR,'cookie.txt');
curl_setopt ($ch, CURLOPT_COOKIE,1);
$content = curl_exec ($ch);
curl_close ($ch);
$cookie = file_get_contents('cookie.txt');
print $cookie;
?>


This works fine, and the cookie gets stored in the cookie.txt file, but it
only ever returns 1 cookie.  There should be 2 for php.net.  Same with
pretty much any other site.  Are there any configuration items I'm missing
for the cookie jar?

[PHP] Does this "directory detection" script work for you?

[John W. Holmes]

Hello. I'm relying on the following code so that a script can 
automatically detect where it's installed and create paths and URLs from 
the information. This way absolute paths and URLs are always used.

I've had a couple people report that the script wasn't finding the paths 
correctly, though, so I'm asking if people could test this out on their 
server and see if it detects the paths or not.


//Determine protocol of web pages
if(isset($_SERVER['HTTPS']) && 
strcasecmp($_SERVER['HTTPS'],'ON') == 0)
{ $protocol = 'https://'; }
else
{ $protocol = 'http://'; }

//HTML address of this program
$dir_name = dirname($_SERVER['SCRIPT_NAME']);
if($dir_name == '\\')
{ $dir_name = ''; }
$html = $protocol . $_SERVER['SERVER_NAME'] . $dir_name;

//Determine web address of current page
$current_page = $protocol . $_SERVER['SERVER_NAME'] . 
$_SERVER['SCRIPT_NAME'];

echo "Path to script: $path";
echo "URL to script directory: $html";
echo "URL to current script: $current_page";
?>
It should print out the file system path to where the script was placed 
as well as a URL to the directory it was placed and a URL to the file 
itself.

I've never had an issue with it personally and I've tested it on Apache 
and IIS on both Windows and Linux. So maybe it's some obscure CGI or OS 
configuration where this isn't working? I just need to know so I can 
plan accordingly.

The only two substitutions that can be made (that I know of) are:

$_SERVER['SCRIPT_NAME'] => $_SERVER['PHP_SELF']
and
$_SERVER['PATH_TRANSLATED'] => $_SERVER['SCRIPT_FILENAME']
If it doesn't work for you, does it work if you do one of those 
substitutions?

Also, this will test if the script is in subdirectories or not, also, so 
testing it within one and seeing if that works, too, is appreciated.

Thanks for any help and time you're willing to provide.

[PHP] PHP /\ UML

[Matthias H. Risse]

Hi,

I wonder if anyone here is aware of UML Tools
for PHP? I know of ArgoUML whichs PHP-codegenerator
seems to be very beta.
Maybe there are or are planned and well intergrated plugins for Zend 
Studio, PHPEd, TruStudio/Eclipse or alike? Basically I would be 
interrested in a solution that really makes it possible to use UML in 
the design and implementation process and which works both ways 
(code->uml, uml->code)..

I hope this is not offtopic for this list, but I couldnt find
any public OO-related one.
Yours,

[PHP] exclude_once(); ?

[Matthias H. Risse]

Hi again!

Question:
Does anyone know of a possibility to exclude files which
have been included _before_ my script starts on the
fly (e.g. at the first lines after the entrypoint) ?
Reasons:
This ISP of my customer somehow includes a bunch of
old PEAR files by default which I dont need or of which I
need in a later version. So when several PEAR-packages
perform a require_once('HTML/foo.php') PHP recognizes that
it has already included foo.php and does not overload with
the one specified in my "user space" code.
Maybe there is a general possibility from blocking
my ISP including some files by default?
Anyone knows why this has become practice by some
ISPs? (Doesnt make sense to me to have overhead
for dozens of requests which scripts most of the
dont require those classes to be used).
Yours,
M

Yuk.  That's awful.  The host should NOT have this set.  The host 
should allow it as an option, but not as a default.

http://www.php.net/ini_set
You can override the auto_append_file value of php.ini with a 
per-directory .htaccess file, with something like (untested):


php_value auto_append_file ''

OR


php_value auto_append_file NULL

... placed in your http document root should do the trick.  Of course, 
if the host doesn't allow per-dir .htaccess files, then you're screwed. 
 I'd move hosts very quick.

Re: [PHP] Does this "directory detection" script work for you?

[Richard Harb]

Hello,

I see one potential problem with this detection in one special case.

This will only occur if you use Apache's feature PATH_INFO.

There $current_page will be inaccurate as the scriptname might
be /index.php but the URL could be /index.php/path/to/mypage or just
/index/path/to/mypage - depending on Apache's configuration and link
presentation.

I mention this because I have used this extensively to work around
having to rely on mod_rewrite.

[PHP] thumbnail problems

[Ninti Systems]

I've searched the archives on this and, while I have turned up some
tips, they don't seem to solve my problem.

I an building a website for an indigenous organisation where jpg images
are uploaded, resized to a standard format, and thumbnails also
generated at the same time (so that is two resizes for each image). Most
of the time this works OK, but there are a lot of pages where many
thumbnails are just blacked out, eg:

http://waru.org/arakuwaritja.php?p=63

On some pages, all images are blacked out, eg:

http://waru.org/arakuwaritja.php?p=36

whereas on others they're all OK, eg:

http://waru.org/arakuwaritja.php?p=43

The people in the field taking and uploading the photos insist that the
format, color depth, etc, is not changing from photo to photo, and I
can't discern any differences. Yet some work, some don't.

I read somewhere that memory limitations could cause this, but still, it
only happens sometimes and not others. We are on a crowded shared server
I think.

I'm use ImageCreateTrueColor() after checking with ImageIsTrueColor(),
otherwise just ImageCreate(). The initial resizes almost always work
(down from 640x480 to 400x300), with the thumbnails it is looking like a
50% failure rate.

Thanks in advance for any assistance.

php's front page will only set one cookie, only in certain
conditions will it set other cookies. I have 4 total from php.net:
  LAST_SEARCH, MYPHPNET, LAST_LANG, COUNTRY

php only set's one cookie on the front page.

This might be a problem, IIRC, some web servers will not set
PATH_TRANSLATED if no PATH_INFO is being passed.

A quick sample of sizes of images does back this thoery up.  Most
pictures I sampled, the full picture's that resized properly were
~16KB, the black icon images original size were ~24KB - ~35KB

I would think that the GD library will complain at some point if
there are memory problems, make sure your settings (on the page
that generates the thumbnails) has error_reporting(E_ALL), and
monitor any errors that occure there.

[PHP] List() help

[PHPDiscuss - PHP Newsgroups and mailing lists]

I'm using list like
list($a,$b,$c,$d) = $MyArray
MyArray holds more than three items, 0-4 more,
my problem is that $d only gets one and I lose the others if more tha one
extra. I know I can just add more $e,f,g,h,i but how do I get the extras
into an array?

TIA

[PHP] $_SESSION <- Learning

[Ross Bateman]

Hi

I am finally starting to try and use register_globals = off on my Servers.
This means a lot of code that has to be checked and changed.

Unfortunatly I am struggeling to come to grips with this new concept (new to
me that is) and was wondering if anybody could give me some pointers.

Getting stumped at my login script.
Once I have checked user and passwords, I pass a few SESSION vars to use
throughout my app.


if ($status == 1)
   {
   //initiate a session
   session_start();
   //register session variables
   $_SESSION['SESSION'];
   //Get DataBase details and connect to it
   include($root_path . "include/vars.php");
   $query = "SELECT * FROM admin WHERE user_name = '$user'";
   $result = mysql_query($query);
   $row = mysql_fetch_object($result);
   //include the username
   $_SESSION['SESSION_UNAME'] = $row->user;
   //include the user id
   $_SESSION['SESSION_UID'] = $row->admin_id;
   //set the SecLevel Session Var
   $_SESSION['SESSION_SEC'] = $row->sec_level;
   //Now do the redirect
   //redirect to Admin Page
   header("Location: ./admin_main.php");
   exit();

   }
else


Where ever I have the $SESSION['var_name'] I used to have a
session_register("SESSION_VAR");
$SESSION_VAR = $row->user;

I then redirect to my app main page and check if a session is registerd to
make sure a user is logged in:

//check that each page is secure
session_start();
//OLD CODE IN SCRIPT = if (!session_is_registered("SESSION"))
if(isset($_SESSION['SESSION']))
   {
   //if session check fails, invoke error handler
   header("Location: ./../error.php?e=2");
   exit();
   }
?>

That all works fine, but when I finaly start to display data on the main
page, nothing shows up.

One of the things I try to display is the name of the user logged in:
>From the login script
//include the username
$_SESSION['SESSION_UNAME'] = $row->user;

then on my main page
echo "logged in as " . $_SESSION['SESSION_UNAME'] . " ";

Needless to say, no data is displayed. anybody able to point out what I
am getting wrong here. It used to work fine before the old way with
register_globals = on.

SIDE Note:
On a Windows PC with Apache, PHP and MySQL installed, even with the
register_globals = on set, the SESSION vars do not work.

Thanks and sorry for the long post,

Ross

I'm  not sure why  you  changed all this.

All you have to do is a simple foreach loop with a counter, and
break when the counter reaches your condition:

$need = 5; /* how many we want */

foreach($this->_content as $index => $item) {

  if ($item['type'] == 'item') {
//...

/* only decrement if its an 'item' */
$need--;
  }
  if (! $need) break; /* we got everything we needed */
}

I wouldn't suggest this method, it is making the assumption that
the indexes are numeric and sequenced from 0..5

Correct, I forgot =0. But as far as I have seen his indices are numeric.

You can prevent the average joe from printing by putting some css
in your document:

@media print { body { display:  none; } }

Try using array_shift[1] for the first few items instead of list:
$a = array_shift($MyArray);
$b = array_shift($MyArray);
$c = array_shift($MyArray);

$MyArray will have the leftovers, you can just assign it if you need a
copy:
$d = $MyArray;

If you only want $d to be an array when there is more than one entry
left do this instead:
if (count($MyArray) == 1) {
 $d = array_shift($MyArray);
} else {
 $d = $MyArray;
}

[PHP] $myobject->$$varname doens't work ??

[greg]

Hello,

I was just trying this but it doesn't work :

class a {
  public $foo = "hello world";
}
$obj = new a();
$varname = "foo";
echo $obj->$$varname;
$bar = "this is working";
$varname = "bar";
echo $$varname; // display "this is working" as expected
?>
Is it a bug or is it normal ?
I didn't find anything about it in documentation (php4 / php5).

Under normal circumstances you don't need to do that (unless you know
what you are doing - but it will not set a cookie on the client side,
it only modifies your superglobal variable for as long as the script
runs. I guess I'm once again stating the obvious).


> followed by a load of the page and a print doesn't show it.

> Do I only call setcookie if the cookie isn't set, or do i call it every
> time I load the page to initialize it?  Once I set it, how do I read it?

Once you setcookie() you can optionally give it something on its way:
like name, value, expire time/date, etc.

You could for example set a cookie to expire in half an hour - i.e.
for a session. It might make sense to refresh that cookie on every
page request, so that a session timeout will be postponed on each
refresh.

If you omit the expire time, it will be valid until the end of the
session (browser closes) - see the docs.


How do you get your cookie back?

If your visitor has a browser that allows cookies and you already sent
him one (or more) before, he will automatically transmit it to you as
part of the HTTP request headers. PHP does its magic and places the
values received into that Superglobal $_COOKIE (as well as $_REQUEST)
for you to play with...

So, if that array is empty that could mean two things:
1) you didn't send any cookie before (either because you already sent
your headers and thus have a f***up in your code or because the
visitor hasn't been to your page before)
2) the visitor does not allow cookies - too bad.


I guess that's all there is to it. Someone correct me or add to that
:)


> Does anyone have any pointers to a basic tutorial?

I didn't use any other page except the obvious one ...
http://www.php.net/manual/en/function.setcookie.php

I hope that answers at least part of what you were looking for ...
