Free class 1.0 software for linux

MRP Base Class 1.0 is an efficient base class for Perl objects that generates the class interface from a definition.

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.

IAM OPML Parser Class parses an OPML file (provided its URL) and returns an array.

OPML (Outline Processor Markup Language) is an XML format for outlines. Originally developed by Radio UserLand as a native file format for an outliner application, it has since been adopted for other uses, the most common being to exchange lists of web feeds (RSS) between web feed aggregators. The OPML specification defines an outline as a hierarchical, ordered list of arbitrary elements. The specification is fairly open which makes it suitable for many types of list data.

The XML elements in an OPML document are:

< opml version=”1.0″ > This is the root element. It must contain the version attribute and one head and one body element. Currently, there’s active work in OML 2.0, which is mainly aimed at solving some of v1.o’s shortcomings.

< head > Contains metadata. May include any of these optional elements: title, dateCreated, dateModified, ownerName, ownerEmail, expansionState, vertScrollState, windowTop, windowLeft, windowBottom, windowRight. Each element is a simple text element. dateCreated and dateModified contents conform to the date-time format specified in RFC 822. expansionState contains a comma-separated list of line numbers that should be expanded o and size of the display window. An OPML processor may ignore all the head sub-elements. If the outline is opened inside another outline then the processor must ignore the window elements.

< body > Contains the content of the outline. Must have one or more outline elements.

< outline > Represents a line in the outline. May contain any number of arbitrary attributes. Common attributes include text and type. The outline element may contain any number of outline sub-elements. While there are many tools to create and/or read OPML files, there are few PHP libraries/functions to work with these files.

This PHP class parses an OPML file (provided its URL) and returns an array with all the parsed data. This array contains, for each of the OPML file’s elements the following attributes: link_url, link_name, link_target, link_description, link_rss, created (date of creation), type (link type: RSS, HTML, etc.). The class uses file_get_contents() to retrieve the contents of the OPML file and then the XML extension is used to parse and store the file’s data in an associative array, where each outline element is stored using a different array index. The array has the following structure:

0 : Array:
{
names => Preface
urls => http://www.php.net/manual/en/preface.php
targets =>
feeds =>
descriptions =>
created => Nov 28 2005 21:05:49 GMT
type => link
}
1 : Array:
{
names => I. Getting started
urls =>
targets =>
feeds =>
descriptions =>
created =>
type =>
}

WebServerInfo PHP class is intended for developer who create software that will run
on different web servers. The project gives a developer a consistent interface
for accessing web servers variables.

Usage:

You have following options:

Option #1
require_once("WebServerInfo.class.php");
$obj = new WebServerInfo();
print $_SERVER[DOCUMENT_ROOT];

Option #2
require_once("WebServerInfo.class.php");
$obj = new WebServerInfo();
print $obj->get(DOCUMENT_ROOT);

Option #3
uncomment the 3rd line from WebServerInfo.class.php
and all you have to do is require the WebServerInfo.class.php class.

Note:
The constructor of WebServerInfo class overrides $_SERVER variable and
variables can be accessed as usual way.


Following base variables are exported if they do not exist.

REQUEST_URI
REDIRECT_URL
DOCUMENT_ROOT
SERVER_SIGNATURE
SERVER_ADDR
SCRIPT_FILENAME

PHP Image Manipulation Class can be used to perform several types of image manipulation operations.
It can rescale images to fit in a given width or height keeping (or not) the original aspect ratio, flip images horizontally or vertically, and rotate images by a given angle while filling the empty spaces with a given color.
All operations preserve transparency. The class does all the error checking for the source and target files. The class supports loading and saving images in the GIF, JPEG, and PNG formats.
Enhancements:
- The crop() method was added.
- The preserveSourceFileTime property was added, which instructs the scripts to preserve the date and time of the source files and pass them on to the target files.
- The flip methods now use the imagecopyresampled function instead of using imagecopy.
- The script no longer crashes when a valid path which is not a file is specified as a source file.
- Error handling for the create_image_from_source_file() private method was fixed, so the script can no longer be easily crashed by specifying bogus source files.

PHP Sessions Management Class is a php class to handle sessions by using a mySQL database for session related data storage providing better security then the default session handler used by PHP.
If you are not familiar with what php sessions are and what are they good for, check out the dedicated chapter in the php manual
If you are familiar with php sessions and you want to use this php class in your projects then remember that to prevent session hijacking, you must not forget to use the regenerate_id() method whenever you do a privilege change in your application
Before usage, make sure you use the session_data.sql file (which is a sql dump file generated with phpMyAdmin) from the install_sql folder to set up the table used by the class
You dont need to modify anything in your previous applications: after instantiating the php class, just use sessions as you would normally.
Note:
The class assumes that there is an active connection to a mySQL database and it does not attempt to create one. This is due to the fact that, usually, there is a config file that holds the database connection related information and another class, or function that handles database connection. If this is not how you do it, you can easily adapt the code by putting the database connection related code in the "open" method of the class.
Enhancements:
- The get_users_online() method is now more accurate as it now runs the garbage collector before getting the number of online users.
- The structure of the MySQL table used by the class was tweaked in so that the "http_user_agent" field was changed from VARCHAR(255) to TEXT to accomodate user agent strings that are longer than 255 characters.
- The "session_data" field was also changed from TEXT to BLOB to help users who store a large amount of data in sessions.

PHP HTML Form Generation and Validation Class is a PHP class for easy HTML form generation and validation.

If youre a web developer you know that designing HTML forms and writing the PHP code for their validation is a really dull task. And if youre like me you mustve looked around the web to see what you can find in order to ease this task.

I made this class first of all because being addicted to coding, I just had to. But what had me really thinking, after looking at some of others people work was: "cool, but what if I have to put the label on top of the text box and not to the left of it? or what if I have to put three controls in a row?" because the vast majority of the HTML form processors Ive seen were just adding the controls one beneath the other and as a webdeveloper I can tell you, besides the login window, I was never asked to build a form where all the controls are just one beneath the other... Now, I am sure that in some of them there were workaround for these things but I wanted it really simple. Oh, and another thing: I wanted the error messages generated by the form validation to be wherever I wanted not just on top, not just on bottom. I want them wherever I feel like theyre looking ok!

So thats why this PHP class is as straightforward as it gets: it provides an easy and intuitive way of handling both HTML form design - based on templates, where you can design your form any way you want, and basic server-side form validation. As this is a BETA version, currently there are only a few validation rules available but you can easily write custom validation rules, both for server-side and client-side.

It provides all the basic controls available in an HTML form plus a date picker control.

In order for the date control to work you must also download the PHP Date Picker Class from the downloads section and configure the PHP Form Generation and Validation Class by setting the datePickerPath property to point to the date picker class!

Youll get a better picture of what Im trying to say by downloading the class and running the example and browsing through the documentation

Suggestions, comments and requests are welcomed.

The code is heavily documented so you can easily understand every aspect of it.
