I hope this is not some homework...
if (preg_match("target", $url)) {
// search and replace
}
else {
// crude but effective, url in form:
// <a href="someplace.html" option="value">link text</a>
$url_array = explode('>', $url);
$new_url = $url_array[0].' target="your_target">'.$url_array[1] . '>';
}
To do a bit more work, search for the position of the first '>', and
then insert a string into the url (eg. with stripos() and
substr_replace()) just before that place.
Of if you really want to put effort in, tokenize the whole url, and
then parse the arguments as you see fit.
