Image processing is needed in almost every web application like creating watermarks, uploading & resizing avatars, cropping them & similar tasks.

Asido is a feature-rich image processing class for PHP that fits to any environment like GD2, Magick Wand and Image Magick. It supports both PHP4 & PHP5 (newer versions support only PHP5).

An example of adding a watermark to an image:

And the code:

<?php
include(’./../../asido/dev/class.asido.php’);
asido::driver(’gd’);
$i1 = asido::image(
      ‘the-source-image.jpg’,
      ‘filename-with-which-you-want-to-save-the-result.png’
);
asido::watermark($i1, ‘put-the-watermark-image-here.png’);
$i1->save(ASIDO_OVERWRITE_ENABLED);
?>

It is really simple and clear.

Asido can:

• resize
• watermark
• rotate
• copy
• crop
• grayscale
• convert

images with ease. To develop faster, Asido is worth a try.

Datetime Toolbocks is a JavaScript library with advanced date parsing that generates date data from the text passed. A simple example would be "today", "next friday", or "last monday".

Secure input and data handling is hard when it comes to HTML because of many different types of malicious code (XSS).

HTML Purifier is a well documented, standards-compliant HTML filter library written in PHP. It simply:

• Removes all malicious code (better known as XSS) with an audited, secure yet permissive whitelist.
• Makes sure your documents are standards compliant. 

HTML Purifier requires PHP 5  (PHP 4 versions are not supported any more but can be downloaded). It saves so much time while developing & offers much more expertise than most of the self-coded data-handling libraries as HTML Purifier is concentrated only in this area.

This open source secure data handling solution also has a comparison chart wih other HTML filters.

Some community-written plugins for CMS softwares, WYSIWYG editors can be found in the HTML Purifier website.
