Removing HTML Comments

[JAG]

Hi guys,

I'm one of those who loves typing a lot of comments in my HTML pages, but would prefer those comments not to be visible if a user does a "view source" on a page. What's the best way--using PHP--to strip comments likes these:

<!-- Some note here. -->

<!--
       Some
       long
       note
       here.
-->

It should NOT strip conditional comments:

<!--[if IE 7]>
<link rel="stylesheet" href="/css/ie7.css" type="text/css" media="screen" />
<![endif]-->

try this:

    $('*').contents().each(function() {
        if(this.nodeType == 8) {
            $(this).remove()
        }
    });

    });

The OP specifically emphasized wanting a PHP solution.

This will strip all comments, but exclude thise that begin with <!--[

PHP Code:

$html = preg_replace( '/\<\!\-\-[^\[].*\-\-\>/Us', '', $html );

Simplest PHP solution is to use PHP comments instead of HTML comments in the first place.

This seems to be what I'm looking for, but how do I implement it as a function? PHP n00b here.

PHP Code:

function removeHTMLComments($html) {
  return preg_replace( '/\<\!\-\-[^\[].*\-\-\>/Us', '', $html );  
}

echo removeHTMLComments($html); 


If you have multiple echos/prints each displaying part of website then it's best that you unify them into simple variable and echo/print it all at once so you wont preg_replace multiple times.
