<li><a href="http://localhost/namesitos/index.php?pg=id=b8f">Title &

To get just the text inside an <a> element, you can try something like this
(untested):

preg_match( '°\<a\s+[^>]+\>(.*?)\</a\>°', $text, $matches )

$matches[1] will then contain the text.

But if you want to remove all HTML, have a look at PHP's strip_tags()
function.

This is one way to do it. Note, that, if the link contains other HTML
elements (like a <span>, for example), those will be returned as part of the
text. Also, the above code only returns the text from the first link it
finds. If you have several links and need the text from all of them, have a
look at preg_match_all().

> is a standard code or you have make for yourself ?

It is a regular expression that I made up to show you a way to a possible
solution. Depending on your exact requirements, you might need to do some
modifications on that code.

....your question makes no sense because you aren't providing any sort
of coherent basis for it. There are lots of different ways to
manipulate strings in PHP, just look through here:
http://us3.php.net/manual/en/ref.strings.php

....if you can't figure your way out from there you probably shouldn't
be trying to program...in anything.

Bullshit! When I started programming I couldnt even understand why I a
line with string that had only numbers could not be used in
arithmethic declarations.... After that I had many problems where
someone like you could have said something like that. God bless I'm
smart enough to ignore such comments, as if I wouldnt be I would never
developed to be fairly good (though not guru) programmer.
