create a 200 character summary from a longer html string

this is a quick function that can create a 200 word plain text summary from a html string. Also added the option to specify the char length of the string. 

Function

function create_summary($html_string, $max_length = 200)

Just add your string and specify the lengh and it will return the summary string. 

PHP

function create_summary($html_string, $max_length = 200) {
	$summary_return = "";
	$html_string_stripped = strip_tags($html_string); // strip the html tags
    if(strlen($html_string_stripped) >= $max_length) { // check if the string is greater than the $max_length value
    	$summary_return = substr($html_string_stripped, 0, 200) . ".."; // add the length summary and some dots on the end.
    } else {
		// just assign the string to the summary and return it as its under the max length anyway
		$summary_return = $html_string_stripped;
	}
	return $summary_return; // return our new summary string.
}

// testing
$my_html = '

Random CSS Property

scroll-padding-right

The scroll-padding-right property defines offsets for the right of the optimal viewing region of the scrollport: the region used as the target region for placing things in view of the user. This allows the author to exclude regions of the scrollport that are obscured by other content (such as fixed-positioned toolbars or sidebars) or to put more breathing room between a targeted element and the edges of the scrollport.
