The extension is a filter to compress the HTML output - to reduce bandwidth.

The filter offers two compression methods:

• GZIP compression
• Trim leading white space and blank lines from HTML output. But does not affect pre, script or textarea blocks.

Heads up: The GZIP compression is turned off for old buggy IE's (< IE7).

Requirements ¶

• Yii 1.1.10 or above...(could work with older versions)
• tested with IE7-9, Firefox 13, Chromium, Safari 5.1

Installation ¶

• Extract the release file under protected/filters
• put in a controller code blocks like the following...

Usage ¶

See the following code example:

GZIP for all actions

/**
	 * @return array action filters
	 */
	public function filters()
	{
		return array(
            array(
                'application.filters.html.ECompressHtmlFilter',
                'gzip'            => (YII_DEBUG ? false : true),
                'doStripNewlines' => (YII_DEBUG ? false : true),
                'actions' => '*'
            ),
		);
	}

GZIP only for index & admin action in controller with CRUD actions

/**
	 * @return array action filters
	 */
	public function filters()
	{
		return array(
            array(
                'application.filters.html.ECompressHtmlFilter',
                'gzip'            => (YII_DEBUG ? false : true),
                'doStripNewlines' => (YII_DEBUG ? false : true),
                'actions' => 'index, admin'
            ),
		);
	}

Trim leading white space, blank lines & new lines from HTML output for all action

/**
	 * @return array action filters
	 */
	public function filters()
	{
		return array(
            array(
                'application.filters.html.ECompressHtmlFilter',
                'gzip'    => false,
                'actions' => 'ALL'
            ),
		);
	}

Nothing will compressed

/**
	 * @return array action filters
	 */
	public function filters()
	{
		return array(
            array(
                'application.filters.html.ECompressHtmlFilter',
            ),
		);
	}
