Is there a way with PHP to have it call a web page, preferably the main page, and grab the contents between these tags <TITLE>blah blah blah</TITLE>

An easy way to grab the contents of a page is simply file_get_contents. using curl might be a more robust solution however.

If you are just parsing the contents of the title tag, a regex might be easiest, but for more complex parsing, the SimpleXML extension might be a good fit.

Here is an example regex.

<?php
$subject = "hello <title>world</title> how are you today";
$pattern = '/\<title\>(.*)\<\/title\>/';
preg_match($pattern, $subject, $matches);
print $matches[1];

<?php
$subject = file_get_contents('http://www.example.com/');
$pattern = '/<title>(.*)<\/title>/i';
preg_match($pattern, $subject, $matches);
print_r($matches[1]);
?>

Use this:

<?php
$data=file_get_contents("www.webpage.com");
preg_match("#(<=<title>).*(?=</TITLE>)#", $data, $matches);
echo $matches[0];
?>

if it's a valid XML file:

$fp=fopen("http://domain.com/file.xml","r");
$contents = stream_get_contents($fp);
fclose($fp);

if ($xml =  new SimpleXMLElement($contents)) {
    echo $xml->title;
} else {
    echo "no title";
}

if it's not a valid xml file:

$fp=fopen("http://domain.com/file.xml","r");
$contents = stream_get_contents($fp);
fclose($fp);

$p1 = strpos($contents,"<title>")+7;
$p2 = strpos($contents,"</title>");

if ($p2 > $p1) {
    echo substr($contents,$p1,$p2-$p1);
} else {
    echo "no title";
}
