php's strip_tags() won't work

I'm trying to tweak a tiny bit a wordpress, but i am level 0 in php, so i kinda suck :/

I want to add a custom 'tweet this' button (i know there already is a gazillion of them, i just wanted to do it on my own, for fun)

So, i'm trying t开发者_JS百科his :

<a href="http://twitter.com/home?status=<?php strip_tags(the_excerpt()) ?>" >tweet this</a>

the_excerpt() returns "<p> ... excerpt ... </p>" and the strip_tags function does not strip those <p> tags !

What do i do wrong ?

Thanks, and sorry if it is obvious.

Your problem is that the_excerpt() does not return its contents to strip_tags(), but outputs it directly using echo. So strip_tags() (which would need a preceding echo by the way to do any work) can't do anything.

Use get_the_excerpt() instead (line break inserted for clarity, remove when using):

<a href="http://twitter.com/home?status=
<?php echo strip_tags(get_the_excerpt()); ?>" >tweet this</a>

By the way, I would also urlencode() the excerpt, you're bound to run into trouble otherwise if it contains "double quotes or other funny characters.

This doesn't look right by common sense: <?php strip_tags(the_excerpt()) ?>, then the WP doc explained, the_excerpt's API doc, it said it echoes instead of returning it. Well, use ob_start to workaround.

ob_start("callback");
the_excerpt();
$excerpt = ob_get_contents();

?>
<a href="http://twitter.com/home?status=<?php echo strip_tags($excerpt) ?>" >tweet this</a>
<?php

Note: I don't have any WordPress API experience.
