Turn on gzip if you want to do it properly. You can also just do something like this:

<pre><code>$this-&gt;output = preg_replace(
 array(
 '/ {2,}/',
 '/&lt;!--.*?--&gt;|\t|(?:\r?\n[ \t]*)+/s'
 ),
 array(

 $this-&gt;output
);

This removes about 30% of the page size by turning your html into one line, no tabs, no new lines, no comments. Mileage may vary

It can be installed as a PHP module and will (correctly, safely) strip whitespace and all other nastiness, whilst still outputting perfectly valid HTML / XHTML markup. It will also clean your code, which can be a great thing or a terrible thing, depending on how good you are at writing valid code in the first place ;-)

Additionally, you can gzip the output using the following code at the start of your file:

In my case I place the following code at the top of a PHP page to minify it:

<pre><code>function sanitize_output($buffer) {

 require_once('min/lib/Minify/CSS.php');

I've tried several minifiers and they either remove too little or too much.

This code removes redundant empty spaces and optional HTML (ending) tags. Also it plays it safe and does not remove anything that could potentially break HTML, JS or CSS.

Also the code shows how to do that in Zend Framework:

<pre><code>class Application_Plugin_Minify extends Zend_Controller_Plugin_Abstract {

 public function dispatchLoopShutdown() {
 $response = $this-&gt;getResponse();
 $body = $response-&gt;getBody(); //actually returns both HEAD and BODY

 //remove redundant (white-space) characters
 $replace = array(
 //remove tabs before and after HTML tags
 '/\&gt;[^\S ]+/s' =&gt; '&gt;',
 '/[^\S ]+\&lt;/s' =&gt; '&lt;',
 //shorten multiple whitespace sequences; keep new-line characters because they matter in JS!!!
 '/([\t ])+/s' =&gt; ' ',
 //remove leading and trailing spaces
 '/^([\t ])+/m' =&gt; '',
 '/([\t ])+$/m' =&gt; '',
 // remove JS line comments (simple only); do NOT remove lines containing URL (e.g. 'src="http://server.com/"')!!!
 '~//[a-zA-Z0-9 ]+$~m' =&gt; '',
 //remove empty lines (sequence of line-end and white-space characters)
 '/[\r\n]+([\t ]?[\r\n]+)+/s' =&gt; "\n",
 //remove empty lines (between HTML tags); cannot remove just any line-end characters because in inline JS they can matter!
 '/\&gt;[\r\n\t ]+\&lt;/s' =&gt; '&gt;&lt;',
 //remove "empty" lines containing only JS's block end character; join with next line (e.g. "}\n}\n&lt;/script&gt;" --&gt; "}}&lt;/script&gt;"
 '/}[\r\n\t ]+/s' =&gt; '}',
 '/}[\r\n\t ]+,[\r\n\t ]+/s' =&gt; '},',
 //remove new-line after JS's function or condition start; join with next line
 '/\)[\r\n\t ]?{[\r\n\t ]+/s' =&gt; '){',
 '/,[\r\n\t ]?{[\r\n\t ]+/s' =&gt; ',{',
 //remove new-line after JS's line end (only most obvious and safe cases)
 '/\),[\r\n\t ]+/s' =&gt; '),',
 //remove quotes from HTML attributes that does not contain spaces; keep quotes around URLs!
 '~([\r\n\t ])?([a-zA-Z0-9]+)="([a-zA-Z0-9_/\\-]+)"([\r\n\t ])?~s' =&gt; '$1$2=$3$4', //$1 and $4 insert first white-space character found before/after attribute
 );
 $body = preg_replace(array_keys($replace), array_values($replace), $body);

 //remove optional ending tags (see http://www.w3.org/TR/html5/syntax.html#syntax-tag-omission )
 $remove = array(
 '&lt;/option&gt;', '&lt;/li&gt;', '&lt;/dt&gt;', '&lt;/dd&gt;', '&lt;/tr&gt;', '&lt;/th&gt;', '&lt;/td&gt;'
 );
 $body = str_ireplace($remove, '', $body);

 $response-&gt;setBody($body);
 }
}

But note that when using gZip compression your code gets compressed a lot more that any minification can do so combining minification and gZip is pointless, because time saved by downloading is lost by minification and also saves minimum.

Here are my results (download via 3G network):

<pre><code> Original HTML: 150kB 180ms download
 gZipped HTML: 24kB 40ms
 minified HTML: 120kB 150ms download + 150ms minification
 min+gzip HTML: 22kB 30ms download + 150ms minification
</code></pre>
