>>why doesn't this code grab the html messages
Because on line 19 of your code you are splitting the data at newlines THEN your regex is examing data (one line at a time) that start with "[...]...".  

The "HTML" code appears on lines that do not start with "[...]" and thus never match.

Try:
preg_match_all('/([0-9:\/]+\s[0-9:]+\s[AP]M)\]\s(\w+)[:]\s([^\[]+)/',$string,$m);
$results=array();
foreach($m[0] as $k=>$v){
	$results[$k]=array("datetime"=>$m[1][$k], "name"=>$m[2][$k],"message"=>$m[3][$k]);
}
unset($m);
echo '<pre>',htmlentities(print_r($results,true)),'</pre>';
exit;
