What a co-incidence, I've just created a similar (though far simpler)
version of this exact plugin and am in the process of testing it on my
sites. If you're interested this is all I did:
---
<?php
class GzCompress extends Plugin
{
public function info()
{
return array (
'name' => 'GzCompress',
'url' => 'http://habariproject.org/',
'author' => 'The Habari Community',
'authorurl' => 'http://habariproject.org/',
'version' => '0.1',
'description' => 'Send gzip compressed data to
browsers that support it.',
'license' => 'Apache License 2.0',
);
}
/**
* Force a low priority to ensure we're the last thing run before
outputting
*/
public function set_priorities()
{
return array( 'filter_final_output' => 100 );
}
public function filter_final_output( $buffer )
{
$HTTP_ACCEPT_ENCODING = $_SERVER["HTTP_ACCEPT_ENCODING"];
if ( headers_sent() )
$encoding = false;
else if ( strpos( $HTTP_ACCEPT_ENCODING, 'x-gzip' ) !== false )
$encoding = 'x-gzip';
else if( strpos( $HTTP_ACCEPT_ENCODING, 'gzip' ) !== false )
$encoding = 'gzip';
else
$encoding = false;
if ( $encoding ) {
$length = strlen( $buffer );
if ( $length > 2048 ) { // Only compress content
greater than 2KB
header( 'Content-Encoding: '.$encoding );
print( "\x1f\x8b\x08\x00\x00\x00\x00\x00" );
$buffer = gzcompress( $buffer, 9 );
$buffer = substr( $buffer, 0, $length );
}
}
return $buffer;
}
}
?>
---
So far my testing has been good.
I've not bothered with bzip or deflate compression as bzip tends to be
too CPU intensive for very little gain and most browsers that support
deflate support gzip.
