Reg-Ex Replacer with Function

[Philipp Lenssen]

I want to do the following (and I suspect the easiest way to be a
regular expression that uses a user-function):

Given the string...
--------
<p>Hello</p>

<p class="bla">World</p>

<h3>Hello User</h3>

<p>How are you</p>
--------
I want to change it to:
--------
<p>Hello</p>

<div class="annotation">That was paragraph 1</div>

<p class="bla">World</p>

<div class="annotation">That was paragraph 2</div>

<h3>Hello User</h3>

<p>How are you</p>

<div class="annotation">That was paragraph 3</div>
--------

So in other words, I want to add a string after every paragraph with a
iterated number. So I suspect I can do the following:

- Replace all "</p>" with "</p>...<div ..$n..." but increase the $n by
1 for every time

Can anybody tell me how to do this? Thanks!

Uhm, OK, a simple explode() did the job...

Use preg_replace_callback():

$annotations = array( ... );
$para_counter = 0;

function anno_callback($match) {
global $annotations, $para_counter;
$annotation = htmlspecialchars($annotations[$para_counter++]);
return "$match\n<div class=\"annotation\">$annotation</div>\n";
}

preg_replace_call('|</p>|i', 'anno_callback', $text);
