Exception::Class is a Perl module that allows you to declare real exception classes in Perl.

SYNOPSIS

use Exception::Class
( MyException,

AnotherException =>
{ isa => MyException },

YetAnotherException =>
{ isa => AnotherException,
description => These exceptions are related to IPC },

ExceptionWithFields =>
{ isa => YetAnotherException,
fields => [ grandiosity, quixotic ],
alias => throw_fields,
},
);

# try
eval { MyException->throw( error => I feel funny. ) };

my $e;
# catch
if ( $e = Exception::Class->caught(MyException) )
{
warn $e->error, "n", $e->trace->as_string, "n";
warn join , $e->euid, $e->egid, $e->uid, $e->gid, $e->pid, $e->time;

exit;
}
elsif ( $e = Exception::Class->caught(ExceptionWithFields) )
{
$e->quixotic ? do_something_wacky() : do_something_sane();
}
else
{
$e = Exception::Class->caught();
ref $e ? $e->rethrow : die $e;
}

# use an alias - without parens subroutine name is checked at
# compile time
throw_fields error => "No strawberry", grandiosity => "quite a bit";

Exception::Class allows you to declare exception hierarchies in your modules in a "Java-esque" manner.

It features a simple interface allowing programmers to declare exception classes at compile time. It also has a base exception class, Exception::Class::Base, that can be easily extended.

It is designed to make structured exception handling simpler and better by encouraging people to use hierarchies of exceptions in their applications, as opposed to a single catch-all exception class.

This module does not implement any try/catch syntax. Please see the "OTHER EXCEPTION MODULES (try/catch syntax)" section for more information on how to get this syntax.

Calendario Class provides a PHP class that is useful for creating calendars and organizers.
Calendario Class is a PHP class that helps you to create calendar and organizers.
Its highly configurable, letting you choose how many days are in a week, when a week starts, the details of the HTML output, and so on.
It also knows about holidays.
Enhancements:
- Added holidays functionality

Validate_fields Class is an easy-to-use form field validation PHP script. This class can be used to validate database inputs or mail forms.
It can validate simple text, numbers, dates, urls, email addresses, and the presence of HTML tags. Invalid form fields will be reported inside a detailed error message.
Enhancements:
- A small improvement in the create_msg() method makes it possible to switch between the XHTML version and the simple HTML version.
- In the fields array one key was named "name", and it has been renamed to "value" to make it more clear.
- The variable declarations at the beginning of the validation method was removed.
- Because the value of a checkbox (radio) type field is only available if the element is checked, there are new functions to validate this elements.

PHP JavaScript Tooltip Generator Class is a PHP class that can generate JavaScript tooltips. The project works on all major browsers, but transparency is not supported on Opera.
In Internet Explorer, the tooltips show above HTML SELECT elements as they should. The appearance of the tooltips is template driven. Only onmouseover/onmousemove events need to be sepcified, not onmouseout.
Further suggestions, comments and requests are welcommed.
Id also really appreciate if you could send me links to the web pages where you are using the class so I can give them as refference and convince more people to use it. Thanks!
The code is heavily documented so you can easily understand every aspect of it
Enhancements:
- in Firefox, the tooltips were showing up in the right position only the first time; after that, the tooltips would show in the top left corner of the screen.
- "Sticky" tooltips can now be created (tooltips that follow the mouse cursor) by calling the "show" method on the onmousemove event rather than on the onmouseover event.
- In Internet Explorer, the vertical scrollbar no longer appears if a tooltip is shown.
- Automatic tooltip re-positioning has been improved in order to keep the tooltip in the visible part of the browser window if it would "flow" outside.
- There is some code cleanup.

PHP HTML Graph Class is a class for drawing vertical bar graphs using only HTML and CSS. Simple and grouped bars can be created. You can change everything regarding the looks as the output is template-driven.
On the fly, you can change the size of graph, the color of all or individual bars, add labels, a title, and footnotes, or customize the CSS style of all elements. The width and height of bars can be specified in pixels or percentages. The code is heavily documented.
Enhancements:
- In some PHP versions, there were some issues regarding passing variables by reference.
- The class would produce no output (nor errors) in PHP versions lower than 5 due to the different implementations of PHPs get_class() function in these versions.
