Take full advantage of ob_start(); ... Magic
ok today i will be talking about ob_start() and how to take advantage of it in a different way than most people
here is a normal usage of ob_start()
Now when you run ob_start it will run threw a process of compressing your data before sending it to the web browser.PHP Code:<?php
ob_start();
?>
<html>
<head>
<title>Ob start Basic Example</title>
</head>
<body>
<div><p>Here is just a paragraph just to act as a content filler</p></div>
</body>
</html>
what where going to do is create our own process for it to run so we then can change the way the data is sent to the browsers.
ok so firstly we need to create a function that will take the data in then process it and then send it t the browser
Now in the LitewarezObHandler() function can do whatever we want to the html so you can create a mini templating system if you wish by replacing {home_link} in the functionPHP Code:$EnableGZipEncoding = true; // if this is true, will return the html gZip'ed
function gZipAllowed(){ //this is a check to see if the browser can accept gZip
$accept = str_replace(" ","",strtolower($_SERVER['HTTP_ACCEPT_ENCODING']));
$accept = explode(",",$accept);
return in_array("gzip",$accept);
}
function cleanHtml($OutputHtml){
now inside this function we can do many things from trimming to removing newlines and carriage returns.
$html = preg_replace("/\s+/"," ",$OutputHtml);//shrinking spaces
$html = preg_replace("/\r+/"," ",$OutputHtml);//shrinking returns
$html = preg_replace("/\n+/"," ",$OutputHtml);//shrinking new lines
return $html;
}
function LitewarezObHandler($OutputHtml){
global $EnableGZipEncoding;
$OutputHtml = cleanHtml($OutputHtml);
if(! gZipAllowed() || headers_sent() || !$EnableGZipEncoding) return $OutputHtml;
header("Content-Encoding: gzip");
return gzencode($OutputHtml);
}
?>
....
so now the usage of this fantastic html controller..
PHP Code:<?php
//make sure that the functions above are included here
ob_start('LitewarezObHandler');
//so what we are doing here is telling ob_start to pass the html data threw my special function
?>
<html>
<head>
<title>Ob start Basic Example</title>
</head>
<body>
<div><p>Here is just a paragraph just to act as a content filler</p></div>
</body>
</html>
heres what a user will see if he looks at your source
Now all your source code will bePHP Code:<html><head><title>Ob start Basic Example</title></head><body><div><p>Here is just a paragraph just to act as a content filler</p></div></body></html>
- Compressed
- Harder to read
- works with 90% of browsers

WareztheDDL.com GTFO.wsit will make your source 1 line?
PHP does a lot of these things that arent really needed though. Like for example. when would this be "needed"?
but fasting loading times and less bandwidth is always a good thing

twilight.ws ddlrank.comLitewarez that's the reason why I can't open your site because it is saying you use a invallid or unsupported method of compression. Just thought you should know.
I can always be contacted by sending a tweet @twilightws
