[RESOLVED] $_SERVER['HTTP_ACCEPT_ENCODING'] and notice in the xhtml service validation .......

[whisher06]

Hi.
I've got a snippet like this:

if(strpos($_SERVER['HTTP_ACCEPT_ENCODING'],'gzip')===false){
	echo $indexController->getPage();
}
else{
    	ob_start();
    	echo $indexController->getPage();
    	$output=gzencode(ob_get_contents(),9);
   	ob_end_clean();
    	header('Content-Encoding: gzip');
	echo $output;
	unset($output);
}

Why on earth I've got this notice:

<br />
<b>Notice</b>: Undefined index: HTTP_ACCEPT_ENCODING in <b>/mounted-storage/home50a/sub001/sc19485-LOWM/www/blogialnewversion/index.php</b> on line <b>25</b><br />

that waste all the validation process.
At the http://www.blogial.net/blogialnewversion/index.php there isn't notice 😕

Best wishes 😉

From http://us3.php.net/manual/en/reserved.variables.php#reserved.variables:

$_SERVER is an array containing information such as headers, paths, and script locations. The entries in this array are created by the web server. There is no guarantee that every web server will provide any of these; servers may omit some, or provide others not listed here.

Thanks a lot buddy.
Do you know any workaround for that ?
By the way is there a better way to gzip output buffer ?

Bye.

<?php
// before any output:
ini_set('zlib.output_compression', 1);

Or set it in your php.ini file or in a local .htaccess file if you want to apply it globally or by directory tree to all PHP files.
