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 = '

For a long time it had seemed to me that life was about to begin - real life. But there was always some obstacle in the way, something to be gotten through first, some unfinished business, time still to be served, or a debt to be paid. Then life would begin. At last it dawned on me that these obstacles were my life.
