Well, if I get you right, you have a class named Project holds 
information about a project. Now you want a list of the current 
projects. I'd make a new class, named ProjectList or something similar, 
that can be used to administrate your projects.

class Project
{
public $name;// The project's name
public $ownerID; // The user ID of the project's owner

/* The constructor. Note: this only works in PHP5 */
public function __construct ($id)
{
$db = mysql_connect();
// Get project info...

$this-name= $result['name'];
$this-ownerID = $result['owner'];
}
}
class ProjectList
{
public $projects = array();
public function __construct ()
{
$db = mysql_connect();
$query  = mysql_query('SELECT id FROM projects');
$result = mysql_fetch_array($query);
foreach ($result as $project_id) {
$this-projects[$project_id] = new Project($project_id);
}
}
public function listProjects ()
{
return $this-projects;
}
public function addProject ($name, $owner)
{
// ...
}
public function deleteProject ($id)
{
// ...
}
}

Who cares whether or not PHP is an object oriented language? If it has

I don't think it's possible. You can, however, ask the user to select

he doesn't have to do it every time he visits the site.

$_SERVER[HTTP_ACCEPT_LANGUAGE] - string with user's language 
preferences. However only a fraction of users willingly set it, so many 
times it will be on its default value, english even for russian speaking 
visitors.
Yup. I think it's better if you let the visitors decide.

I'm not quite getting what you're saying - are you sending the error

the good 'ol OR operator:

do_something() or die('Couldn\'t do it, sorry...');
Well, maybe an IF then:
if (!do_something()) {
exit('Still can\' do it...');
}
But there are also much more sophisticated ways of doing it. Clarify

If you want an argument to be optional and still be able to check 
whether or not it's been set, you can use NULL as the default value:

That check should be for 'is_null($c)' as the default value of $c will
be null, and it will be always set, even if not sent.

isset(null) evaluates to false...

Dunno 'bout the proxy part, but can't you just have a MySQL table like this:
id INT; ip VARCHAR(15); time DATETIME; PRIMARY KEY id
Then check if the client IP exists in the table upon page load. If it 
does, update the timestamp. Otherwise insert a new row. After the query 
you delete all rows that are more than 5 or so minutes old.

Bottom Line:

Better use

As far as I know the only errors you can handle through a user-defined 
function are of levels E_USER_ERROR, E_USER_WARNING and E_USER_NOTICE.

php.net (http://dk2.php.net/manual/en/function.set-error-handler.php) 
says this:

Note:  The following error types cannot be handled with a user defined 
function: E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, 
E_COMPILE_ERROR, E_COMPILE_WARNING, and E_STRICT.

class Foo

Re: [PHP] Multi-User Text-Editing

2004-09-07 Thread Daniel Schierbeck

Okay, i got the general idea, now it all comes down to the actual 
writing. I'm making a function that compares two strings (the one in the 
source i read used an exec() call, but i'd like to do it all in PHP) 
per-line. This poses some difficulties. Here's the scenario:

I want to determine whether or not two lines are identical.
If they're not:
- Has the line simply been edited?
- Is it a completely new line?
- Has the line been deleted?
To do so i'll have to run a loop, checking each line. But here's where 
the problem is:

?php
$str1 = NEWTXT
Once there was a Bar
It was red
It had some Foo
Underneath its Foobar
NEWTXT;
$str2 = OLDTXT
Once there was a Bar
It had some Foo
Underneath its Foobar
OLDTXT;
$arr1 = explode('\n', $str1);
$arr2 = explode('\n', $str2);
$count = 0;
foreach ($arr1 as $line_num = $line) {
if (isset($arr2[$count]  ($line === $arr2[$count]))) {
echo Unchanged \ . $line . \\n;
} elseif ($line !== $arr2[$count]) {
echo Changed to \ . $line . \ from \ . $arr2[$count] . 
\\n;
} elseif (!isset($arr2[$count])) {
echo Added \ . $line . \, was  . $arr2[$count] . \\n;
}
$count++;
}
?
Then i'd get something like this:
Unchanged Once there was a Bar
Changed to It was red from It had some Foo
Changed to It had some Foo from Underneath its Foobar
Added Underneath its Foobar
Where the second, third and fourth line is wrong - i added a line 
between There was a Bar and It had some Foo...

How should i do this?

[PHP] Multi-User Text-Editing

I'm developing a site with information about songs, albums and artists. 
I would like to have the song lyrics as well, but i don't know how i 
should approach it.

What i want is basically a way for many users to update, add or delete 
parts of a text (the lyric). It will probably only be 'trusted' users 
that'll be able to do it (users that has added more than x 
artists/albums/songs). How can i make a CVS-like system, where you can 
see the changes people made, maybe roll back to an earlier version etc. 
etc.?

I think i'll use MySQL, but if you think it's easier to use XML or 
something else, that'll be fine with me (as long as it's generally 
available).

Thank you in advance guys :)

Wow, confusing code - but i think i got the idea. Just one thing: After 
reading the code, it seems to me that every time someone makes a change 
to a record, a new row is inserted into the DB with the full text of the 
edited record - not just the changes. I saw that there was an automatic 
expiration function, but still, wouldn't it be a drag for the server?

Hello everyone,
 

I want to build a music site, all copyrights intact, and I want users to be
able to download mp3 or realplayer files using a one-click link. When they
click on a link they will simply be given a typical download window to save
that music file. How do I go about doing that and how should my file
structure work? What should the link include? Is it possible to just say,
for example, http://somesite.com/music/something.mp3?
If you want more control over the files you could have the mp3's in a 
private directory, then using PHP to force a download. There are some 
other threads about the Content-Type header, which is probably what 
you're looking for

Imagine that your file, 3416.mp3 is in /songs. 3416 is the song ID, so 
you can grab info such as artist, album and song name from a DB. Below 
is download.php, to download 3416.mp3, you should type 
download.php?file=3416

?php
	if (!isset($_GET['file']) or !file_exists('songs/' . $_GET['file'] . 
'.mp3')) {
		die(No file selected);
	} else {
		$file = $_GET['file'];
	}

$db = mysql_connect();
// More DB stuff
$artist = $row['artist']; // The artist name from the DB
$album  = $row['album']; // ...
$song   = $row['song']; // ...
$filename = $artist . '-' . $album . '-' . $song . '.mp3';
header('Content-Type: application/force-download');
header('Content-Length: ' . filesize('songs/'.$file.'.mp3'));
header('Content-Disposition: attachment; filename=' . $filename . '');
header('Content-Transfer-Encoding: binary');
readfile('songs/' . $file . 'mp3');
exit();
?

Also, if I wanted them
to listen to streamed music does PHP have any specialized functions I could
use to achieve that? 
You should take a look at the Ming library and the mp3 stream function 
(http://www.php.net/manual/en/function.swfmovie.streammp3.php). It's a 
bit tricky though, but i can't think of anything else.

Re: [PHP] [PHP5] paradox ? Bug ?

2004-09-03 Thread Daniel Schierbeck

I think this basically sums up the problems of the current handling of 
existence-checking in overloaded objects: We have an object that has 
user-defined methods for getting and setting object properties (__get() 
and __set(), respectively). These methods get and set the properties in 
a private array (private: can only be access from within the object 
itself). Example (mostly stolen from php.net):

?php
class Foo
{
// This array holds the properties
private $elem = array();
// This method is automatically called when an
// undefined (or inaccessible, as $array) property is
// called. The name of the called property is the only
// argument.
public function __get ($prop)
{
if (isset($this-elem[$prop])) {
return $this-elem[$prop];
} else {
trigger_error(Oooops, E_USER_WARNING);
}
}
// Same as before, but is called when setting a
// property
public function __set ($prop, $val)
{
$this-elem[$prop] = $val;
}
}
// Instantiate the class
$foo = new Foo();
// Check if $foo-bar ($foo-elem['bar']) is set
if (isset($foo-bar)) {
echo \$bar is set\n;
} else {
echo \$bar is not set\n;
}
// Set $foo-bar to 'foobar'
$foo-bar = 'foobar';
// Print the value of $foo-bar
echo $foo-bar, \n; // foobar

// Check if $foo-bar ($foo-elem['bar']) is set
if (isset($foo-bar)) {
echo \$bar is set\n;
} else {
echo \$bar is not set\n;
}
?
Now, since we access the properties of $foo in a 'virtual' manner - 
meaning $foo-bar doesn't really exist, it's actually $foo-elem['bar'] 
(if it were public, that is) - we can assume that we can check for 
property existance in the same 'virtual' way, right? Wrong. If we could, 
the above would output this:

$bar is not set
foobar
$bar is set
Yet it returns:
$bar is not set
foobar
$bar is not set
If we want to check whether or not $bar exists in $foo, we have to add a 
method to the Foo class:

public function isSet ($prop)
{
if (isset($this-elem[$prop])) {
return TRUE;
} else {
return FALSE;
}
}
Which is rather dumb, considering that the intention of isset() is to 
check whether or not a variable exists!

So far there has been two suggestions as to what can be done:
1. Change isset so that it automatically detects
   overloaded properties
	2. Let the user define a custom __isSet() method, similar to the 	 
one above, that is called each time a property of the class
	   is checked with isset()

Maybe there's some other angles/ideas/suggestions?

[PHP] Statistics

2004-09-02 Thread Daniel Schierbeck

I'm trying to develop a set of functions that can handle the statistics 
of a website. I want them to be as flexible as possible, and i want to 
be able to have several different views (day, week, month, year). For 
example if i wanted to know how many visitors, visits and page hits 
there was each month last year, i could call the function like this:

$months = Statistics::getStats(STAT_VIEW_YEAR, 2004);
foreach ($months as $month) {
echo $month['visitors'];
// ...
}
I'm thinking of doing it like this:
?php
class Statistics
{
public static function logPageView ()
{
global $db; // $db is just a MySQL object interface
$ip = $_SERVER['REMOTE_ADDR'];
$ex = STATS_SESSION_EXPIRE;
			$result = $db-query(UPDATE `statistics` SET `visit_end` = NOW() AND 
`hits` = `hits`+1 WHERE `ip` = '$ip' AND NOW()-`visit_end`  $ex ORDER 
BY `visit_start` DESC LIMIT 1);
		
			if ($db-affectedRows() !== 1) {
$db-query(INSERT INTO `statistics` (ip, visit_start, visit_end) 
VALUES ('$ip', NOW(), NOW()));
			}
		}
	
		public static function getStats ($view = STATS_VIEW_DAY, $date)
		{
			global $db;
			
			switch ($view) {
case STATS_VIEW_YEAR:
	$sql = YEAR(visit_start) = $date GROUP BY MONTH(visit_start) ORDER 
BY MONTH(visit_start);
	break;
// More cases
default:
	return FALSE;
			}

			return $db-query(SELECT COUNT(DISTINCT ip) AS visitors, COUNT(*) AS 
visits, SUM(hits) AS hits FROM `statistics` WHERE  . $sql)-fetchArray();
		}
	}

?
Is there a simpler way of approaching this?

[PHP] Re: Handling XML output in a slim way

Hi,
up until now, when outputing XML I've been constructing the output as a 
continous string-soup in such ways like

makeXmlSave() makes sure that quotes, ampersand,  and  are properly

possible to e.g. generated a a complete DOM tree first and then just 
having this tree being dumped as XML.

I'm using PHP4 right now.
thanks,

In PHP5 the simplexml functions make it very easy to read/edit XML 
documents. For instance

friends.xml:
friends
friend
nameCharlotte/name
age21/age
/friend
friend
nameDan/name
age25/age
/friend
friend
nameJennifer/name
age19/age
/friend 
/friends
With simplexml you can load that XML document into an object:
?php
$friends = simplexml_load_file('friends.xml');
foreach ($friends-friend as $friend) {
echo Name: {$friend-name}; Age: {$friend-age}\n;
}
?
Which would output:
Name: Charlotte; Age: 21
Name: Dan; Age: 25
Name: Jennifer; Age: 19
You can also edit the object and save it, either as an XML file or as an 
XML-formatted string. Search for 'simplexml' on php.net to see the full 
documentation.

But it only works in PHP5 ;)

Next time, please read my post carefully. $a is not NULL, it is 1. 
Therefore, isset($a) should return TRUE, which it does normally, just 
not when $a is returned via __get().

@catalin: Yes, a __isset() method would be ideal, but i still can't see 
why isset() shouldn't support the overloaded variables - after all, if 
you are able to access such a variable using the __get() method, why 
shouldn't you be able to check whether or not it has been set? 
Currently, if you want to check whether a variable in the $elem array is 
set, you would have to use this:

$a = $o-a;
echo isset($a) ? yes\n : no\n;
Which in my opinion isn't optimal.
Bottom line - if you can access a variable through property overloading 
you should be able to use isset() on them as well.

Actually i think no property is created; not in the sense of

The only real property of the object is $elem.
The $o-a, and $o-b are, IMHO, not object properties;
It is true that one can access $o-a and $o-b, but what is actually
returned is a member of the array $elem, and only because of the
implementation of the magic functions __set and __get.
isset() does test for an actual variable beeing set, which is 
definetely
not the case.
I agree however that this is confusing. I am definetely puzzled by the
usefullness of these methods since i consider this to be a real error trap;
it would be so easy to fill up an object with values without knowing
what they are and what they are supposed to do and when developing some
kinda library, things can get really messy.
On my part I would stick with the usual declaration of properties and 
not
use __set() and __get().
I think it's much cleaner to say:
class OO {
/** this is variable a and means ... */
public $a;
/** this is variable a and means ... */
public $b;
}

Frédéric hardy [EMAIL PROTECTED] wrote in message

Yes but not :-).
With you use these magic functions, when you write $o-a = 'foo', you 
create a property in the object. Not ? Even if it is stored in an array 
member, __set() create a property and __get() retrieve its value.

Doc says :

The $name parameter used is the name of the variable that should
be set or retrieved.
The __set() method's $value parameter specifies the value that
the object should set set the $name.
Conclusion :
class OO
{
  private $elem = array();
  public function __get ($prop)
  {
 if (isset($this-elem[$prop])) {
return $this-elem[$prop];
  }
  else
  {
 return NULL;
  }
  public function __set ($prop, $val)
  {
 $this-elem[$prop] = $val;
  }
}
$o = new OO();
echo isset($o-a) ? yes\n : no\n; # Must return false and return false 
effectively, cool
$o-a = 'foo';
echo isset($o-a) ? yes\n : no\n; # Must return false and return false 
effectively, NOT COOL

I personally find the __get() and __set() methods very usefull, 
especially when constructing object hierarchies. But, as Frédéric said, 
they're not sufficient. Either make isset() work with the __get() method

well, you can access strings like arrays already. So instead of

$var = 15 is a number;
$var[2] = 7;

echo $var;
// will output: 17 is a number
same way goes for accessing them
In PHP5, the square brackets have been replaced with the curly ones (the 
square brackets still works, but it's deprecated)

$string = 12345;
echo $string{2}; // 3

The method get_declared_classes() only shows only the classes included/required.
There's no predefined variable or method for determining this, that I'm

Ooops, didn't see your post, hehe...
By the way, use self instead of Foo, just in case you change the 
class' name.

ob_get_clean() is preferable:

the buffer

Didn't need the contents of the buffer. All I needed was the last line 
which was contained in $output = system().

Sorry, my bad...

No, this is not a bug. This means that if you define a new constructor
/ destructor, the parent class's won't be called unless you put it in
the new ones.

Although not a bug, it is a little misleading, i've corrected it to
explain when the constructor isn't called.

Thanks, all i needed to know :)
The manual's a bit confusing on that part...

[PHP] Re: Cookie behaviour

2004-08-23 Thread Daniel Schierbeck

Michael Purdy wrote:
Folks
I am running php 5.0.1 on NT.  

I have a small test script as shown below
script language=php
  setcookie('cat','large',time()+3600);
  setcookie('dog','small',time()+3600);
/script
The outcome of this script is that only the LAST cookie is successfully stored.despite 
having a different
name.  Is this because they are both being set from within the same script and 
therefore conflicting with
each other?
Mike
First of all, use ?php and ? instead of script language=php and 
/script, the latter is not always supported. Second, are you sure that 
you don't output any non-header information to the browser before 
setting the cookies? Try using output buffering:

?php
/* start output buffering */
ob_start();

/* print out something stupid (it is saved to the buffer) */
echo mooo\n;
/* set them cookies */
setcookie(foo, bar);
setcookie(bar, foo);
/* it's getting even stupider (can you even say that?!) */
echo baaah\n;
/* print the buffered output and end the output buffering */
ob_flush();
?

Daniel

Re: [PHP] How do I open Save As Dialog Box?

Ave,
I'm facing a little problem.
I have created a File Manager Application for my company which has a place

various MIME Types.. Mainly PDF, TXT  DOC.
What I want to do is basically... When the user clicks on the Download
Button... The Save As Dialog Box should appear...
What is happening right now is that the file opens in it's related software
(Word, Acrobat, Notepad etcetera). I don't want the file to open in it's
native software.
I know I need to use the
header (Content-type: application/octet-stream);
But I don't know how.
Can anyone help?
Thanks.
Try using header(Content-type: application/force-download)

[PHP] Class Con- and Destructor Inheritance

Hello there. I was experimenting a bit with the constructors and 
destructors, and found that this code:

?php
class First
{
public function __construct ()
{
echo Hello, World!\n;
}

public function __destruct ()
{
echo Goodbye, World!\n;
}
}
class Second extends First
{
}
$second = new Second;
?
Outputs
Hello, World!
Goodbye, World!
, yet the PHP manual 
(http://www.php.net/manual/en/language.oop5.decon.php) says:

Note:  Parent constructors are not called implicitly. In order  
to run a parent constructor, a call to parent::__construct() is
required.
Is this an error in the manual or in PHP itself? Should I report it 
somewhere?

i just read, that objects in php 5 automatically returned as reference? 
in my code it doesn't seems like that!!

ps: variable m_objData contains a lot of data from a mysql db
thanks for answers.
As you can read in some of the posts here, it only SEEMS like the 
objects are passed by reference (it's a conspiracy!). I'm not sure if 
it'll help you, but try using the ampersand () symbol to force 
passing-by-reference.

Cheers,
Daniel

I depends on what kind of database you wish to use (you probably have 
MySQL, though PostgreSQL would be preferable). If you have a large 
amount of lines I recommend you use prepared statements. But first of 
all, tell us which database you're going to use.
