how do I limit the number of characters?

Hi, this is a general query.
I am pulling an rss feed from my vanilla chat site, over to another section of my site (a non vanilla section).
A poster had posted the code below, which I amended, and put in my rss feed url. The feed now appears at the top of my right hand sidebar, as planned.
http://www.love2escape.com/multitrackers/
But, I want to limit the number of characters that appears in each post in the feed.
How would I do that? TIA
Here is the existing code.
<?php
set_time_limit(0);
$file = "http://www.love2escape.com/chat/search/?PostBackAction=Search&Keywords=&Type=Comments&btnSubmit=Search&Feed=RSS2";
$TOTALITEM_WANTED=5; //any number of links
$rss_channel = array();
$currently_writing = "";
$main = "";
$item_counter = 0;
function startElement($parser, $name, $attrs) {
global $rss_channel, $currently_writing, $main;
switch($name) {
case "RSS":
case "RDF:RDF":
case "ITEMS":
$currently_writing = "";
break;
case "CHANNEL":
$main = "CHANNEL";
break;
case "IMAGE":
$main = "IMAGE";
$rss_channel["IMAGE"] = array();
break;
case "ITEM":
$main = "ITEMS";
break;
default:
$currently_writing = $name;
break;
}
}
function endElement($parser, $name) {
global $rss_channel, $currently_writing, $item_counter;
$currently_writing = "";
if ($name == "ITEM") {
$item_counter++;
}
}
function characterData($parser, $data) {
global $rss_channel, $currently_writing, $main, $item_counter;
if ($currently_writing != "") {
switch($main) {
case "CHANNEL":
if (isset($rss_channel[$currently_writing])) {
$rss_channel[$currently_writing] .= $data;
} else {
$rss_channel[$currently_writing] = $data;
}
break;
case "IMAGE":
if (isset($rss_channel[$main][$currently_writing])) {
$rss_channel[$main][$currently_writing] .= $data;
} else {
$rss_channel[$main][$currently_writing] = $data;
}
break;
case "ITEMS":
if (isset($rss_channel[$main][$item_counter][$currently_writing])) {
$rss_channel[$main][$item_counter][$currently_writing] .= $data;
} else {
$rss_channel[$main][$item_counter][$currently_writing] = $data;
}
break;
}
}
}
$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
if (!($fp = fopen($file, "r"))) {
