[PHP] Error Handling question
Hi,
I am new to PHP and need some help for error handling.
I read in the docs that i can handle the errors this way in my PhP:
set_error_handler('errorHandler');
function errorHandler($errnum,$errmsg,$file,$lineno){
[...]
}
But does that mean that I have to copy paste this code in all my Php pages
or is there a better way ?
Thank you.

You could first check if the variable consists only of numbers. If so,
it's likely a timestamp. If $var does consist of something other than
digits, pass it to strtotime() first.
$arr_date = (
ctype_digit($var)
? getDate($var)
: getDate(strtotime($var))
);
Finally, check that the date is legitimate:
if (checkdate($arr_date['mon'], $arr_date['mday'], $arr_date['year']))
{
...

Hi Matt,
The problem here is that you're using echo statements, which output
directly. Instead you need to build a string containing this output, for
example:
$body = Hello, here is your quote from Freight Services.br /br /;
$body .= Shipping from: tab $origin to $destinationbr /;
etc.
Note the use of the .= operator. This is the same as saying $body =
$body.'whatever';
At the end, $body will then contain the HTML body of your email which you
pass to the mail function.
Hope this helps,
Edward

[PHP] Saving
Has anyone had to save the insance of a class which had a properties which were pointers? I have a really simple class. Just a few functions and a couple properties variables. But now I need to be able to save the class to a file. Of course when you re-open the file the pointers will be useless. I was thinking and the only way I came up with storing this to file would be to get the Name of the TTabSheets and the Text of the Node. That way when I read it back in I just have to search for those names in the PageControl and Tree by looping through and set those.

[PHP] How to implement a plugin system?
Hello all, I am working on a project which needs to have some sort of plugins architecture and I am kinda stuck. Basically I want to give a list of items to the user, and according to his/her selection, I want to load relevant functionality into my application. I was thinking of having an abstract plugin class, and have the plugins implement that but then how would I actually load the plugins? Say for instance I want to load plugins X,Y,Z (and lets say i implemented them as [X|Y|Z].class.php) , should I just 'include' (or require) them? Or should I initialize all possible plugins and just pick the ones user has chosen (which sounds a bit pointless as it would load unnecessary stuff)? How would you go about doing something like this?

Re: [PHP] How to implement a plugin system?
Hello Boro, Thanks for your response. However I am looking for something a bit more comprehensive :) I could do it as you suggested if I had only a few plugins. As I am going to add loads of plugins over the time, rather than adding all the plugins one by one, could something like a 'loader' class be implemented? What I mean by that is, it will take the requested plugin names (with their own parameters necessary) and load/initialise them. In semi-psuedo-code, it would be something like: foreach plugin suplied as the argument include the plugin initialise it end Perhaps I should change the question to: Do you think something like this would be efficient and useable? If not what sort of pattern would you follow? Warm regards, Hamza. Borokov Smith [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hey Hamza, require_once($chosenPlugin .

I would suggest you name your plugins X_plugin, Y_plugin and Z_plugin (where plugin could be anything) because that adds a level of security.

Re: [PHP] Saving
Aww fuck! I clicked the wrong newsgroup. Sorry about that guys. Stut [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Dan wrote: Has anyone had to save the insance of a class which had a properties which were pointers? I have a really simple class. Just a few functions and a couple properties variables. But now I need to be able to save the class to a file. Of course when you re-open the file the pointers will be useless. I was thinking and the only way I came up with storing this to file would be to get the Name of the TTabSheets and the Text of the Node. That way when I read it back in I just have to search for those names in the PageControl and Tree by looping through and set those. Although this would probably work it's probably not the best way to do it right? TPage = class private pge: TTabSheet; par: TTabSheet; txt: String; show: Boolean; node: TTreeNode; function GetTab: TTabSheet; procedure SetTab(Tab: TTabSheet); function GetText: String; procedure SetText(text: String); public Constructor Create; overload; Constructor Create(pg: TTabSheet; text: String; pare: TTabSheet = nil; showProp: boolean = true); overload; property page: TTabSheet read GetTab write SetTab; property text: String read GetText write SetText; end; That looks a lot like Delphi not PHP.

[PHP] Thoughts about music library
I'm building an web interface for my music collection. What I would like is some opinions on what to choose pro/cons: The first choice I took was to stream music directly to a player, i.e. I construct and export an m3u with php and open that with any player. This gives me an external playlist independent of browser screen. The loosing choice was to use icecast to stream. Here I can construct an online playlist witch shows whats up next, what was the last song, and skip back/forth... so on. This would mainly be for programmin excersice, any takers on pros? The next thing would be the playlists, I would like an option to save them for further use. My playlist so far is either that I enter a directory and press play. This would put all the files in this directory (not recursive) into a playlist and export, or I press one single file and a m3u gets exported. I can easily save this file as the... well... last playlists sorted after date or whatever, but how would I go on if I wanted to add songs. Here I was thinking about making a button behind each song or directory and have a js sort of table to one end of the screen witch add,update or gives me the choice to delete a song/album... This seems like a screenfilling option of sorts, anyone else with a less extensive, prettier or just a better solution? -- --- Børge http://www.arivene.net --- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Can anyone point me toward some useful resources?
greg, how is your application written? is it fairly modular? you could build an n-tier system by assigning different components of the application to different pieces of hardware. then you could have the components communicate via a local high speed network. soap would be a good protocol for the communication. http://www.phppatterns.com/docs/design/a_quick_intro_to_ntier?s=tier caching is a common performance tool as well. this is a different approach though, but can be used in tandem w/ the n-tier concept. -nathan On 8/6/07, greg patmore [EMAIL PROTECTED] wrote: Hi all, I was wondering if anyone could point me toward some good resources regarding suggestions on handling user preferences over a cluster in a heavy traffic website.

Namely what you want is the Strategy pattern. Strategy allows you to compose objects at run time dynamically, thereby changing behavior in your system on-the-fly. The components are made similar by a common interface, which can be either the PHP *interface* or the PHP *abstract class*. these components each encapsulate a different algorithm or module as you would call it. and the interface makes the system simple to extend. to create a new module you simply implement the interface and it is interchangeable with the other modules in the system. the factory method pattern is sort of complex. it is used to encapsulate object creation. it is typically used to instantiate objects in a *family* *of products* which is defined by a common interface, ie the strategy pattern. the factory method is used to create products in a standard way. factory method pattern goes further, in typical implementations, by using template method in a parent class. this controls the boundaries of the modules in the system. the template method invokes the a factory method on a subclass to get a concrete object. it then operates on the the concrete object in a predefined sequence. the abstract base class can define different types of methods. the base class may specify methods that must be implemented by concrete subclasses. it can also expose hook methods, with a default implementation. these methods can be optionally implemented in the subclasses. after invoking the factory method to get a concrete object the factorys template method will invoke the remaining methods, mandatory, hook or otherwise on the newly created concrete object in a predefined sequence before handing the new object to the client code that called it. http://www.phppatterns.com/docs/design/strategy_pattern http://www.phppatterns.com/docs/design/the_factory_method -nathan
