I recently needed a function to do exactly the same thing. I modified one I found on PHP.net

It isn't 100% perfect but it does the job.

function html_substr($posttext, $minimum_length, $length_offset) {
// The approximate length you want the concatenated text to be
$minimum_length = 200;
// The variation in how long the text can be
// in this example text length will be between 200-10=190 characters
// and the character where the last tag ends
$length_offset = 10;
// Reset tag counter & quote checker
$tag_counter = 0;
$quotes_on = FALSE;
// Check if the text is too long
if (strlen($posttext) > $minimum_length) {
// Reset the tag_counter and pass through (part of) the entire text
for ($i = 0; $i < strlen($posttext); $i++) {
// Load the current character and the next one
// if the string has not arrived at the last character
$current_char = substr($posttext,$i,1);
if ($i < strlen($posttext) - 1) {
$next_char = substr($posttext,$i + 1,1);
}
else {
$next_char = "";
}
// First check if quotes are on
if (!$quotes_on) {
// Check if it's a tag
// On a "<" add 3 if it's an opening tag (like )
if ($current_char == "<") {
if ($next_char == "/") {
$tag_counter++;
}
else {
$tag_counter = $tag_counter + 3;
}
}
// Slash signifies an ending (like or ... />)
// substract 2
if ($current_char == "/") $tag_counter = $tag_counter - 2;
// On a ">" substract 1
if ($current_char == ">") $tag_counter--;
// If quotes are encountered, start ignoring the tags
// (for directory slashes)
if ($current_char == "\"") $quotes_on = TRUE;
}
else {
// IF quotes are encountered again, turn it back off
if ($current_char == "\"") $quotes_on = FALSE;
}

// Check if the counter has reached the minimum length yet,
// then wait for the tag_counter to become 0, and chop the string there
if ($i > $minimum_length - $length_offset && $tag_counter == 0) {
$posttext = substr($posttext,0,$i + 1) . "...";
return $posttext;
}
}
}
return $posttext;
}

i suck at doing it, but look into the http://www.php.net/manual/en/function.eregi-replace.php function to replace everything between the < and > (including the <>'s) with an empty string.
