How to change the text after extract it in PHP?

I'm working on my website to extract the data and I want to change text I
actually want. I'm stored the website link in MYSQL database where I can
output the link in PHP and I'm using PHP DOM to extract the data. I have
extracted the text which I got "College Football "Texas Christian at Texas
Tech" LIVE " using with this code:
<?php
define('DB_HOST', 'localhost');
define('DB_USER', 'myusername');
define('DB_PASSWORD', 'mypassword');
define('DB_DATABASE', 'mydbname');
$errmsg_arr = array();
$errflag = false;
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link)
{
die('Failed to connect to server: ' . mysql_error());
}
$db = mysql_select_db(DB_DATABASE);
if(!$db)
{
die("Unable to select database");
}
function clean($var)
{
return mysql_real_escape_string(strip_tags($var));
}
$channels = clean($_GET['channels']);
$id = clean($_GET['id']);
if($errflag)
{
$_SESSION['ERRMSG_ARR'] = $errmsg_arr;
echo implode('<br />',$errmsg_arr);
}
else
{
$insert = array();
if(isset($_GET['channels']))
{
$insert[] = 'channels = \'' . clean($_GET['channels']) .'\'';
}
if(isset($_GET['id']))
{
$insert[] = 'id = \'' . clean($_GET['id']) . '\'';
}
if($channels && $id)
{
$qrytable1="SELECT id, channels, links FROM tvguide WHERE
channels='$channels' && id='$id'";
$result1=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br
/>' . mysql_error());
while ($row = mysql_fetch_array($result1))
{
$links = $row['links'];
include ('simple_html_dom.php');
$html = file_get_html($links);
$title1 = $html->find('a[id=rowTitle1]', 0); // with this
echo $html->find('li[id=row1-3]', 0)->plaintext;
echo "<BR></BR>";
}
mysql_close($link);
}
}
?>
Here's the HTML source after I extract it:
7:30 PM College
Football
"Texas Christian at Texas Tech"

LIVE
<BR></BR>
I can see in the HTML source that there are long space which I want to get
rid it and I also want to ignore the time including AM and PM.
I want to change in the HTML source from this:
7:30 PM College
Football
"Texas Christian at Texas Tech"

LIVE
<BR></BR>
to this:
<span id='title1'>College Football: Texas Christian at Texas Tech -
LIVE</span><br></br>
Could you please tell me how I can change the text I want using my current
code?
