I'm trying to replace text with a link. The regex I now have, replaces all matches but I only want to replace the first two occurrences.
It should replace all occurrences of find me with a link, except when it is located in a or tag.

My current regex:
/<(a|h[1-6])[^>]*>(?:[a-zA-Z0-9\s\'\-\.,]|(?:<(.*)>.*<\/\1>))*<\/(a|h[1-6])>(*SKIP)(*FAIL)|\b(Find Me)\b(?=[^>]*(?:<|$))/ig
My dummy content:
Lorem ipsum find me and skip when
<b>find me</b> is inside a link tag
like this find me
<h1>find me in the title</h1>
<a href="#">here you can find me too</a>.
<h2 class="heading">Lorem Ipsum dolor find me here too</h2>
<table>
<tr><td>Cell 1 a</td><td>Find me</td></tr>
<tr><td>Cell 2 with find me</td><td><a href="#foo">Find me</a></td></tr>
</table>
<h3 class="heading">Duomo Di find me San Martino</h3>
<p>FIND ME as well</p>
My PHP preg_replace:
$text = 'Lorem ipsum find me and skip when
<b>find me</b> is inside a link tag
like this find me
<h1>find me in the title</h1>
<a href="#">here you can find me too</a>.
<h2 class="heading">Lorem Ipsum dolor find me here too</h2>
<table>
<tr><td>Cell 1 a</td><td>Find me</td></tr>
<tr><td>Cell 2 with find me</td><td><a href="#foo">Find me</a></td></tr>
</table>
<h3 class="heading">Duomo Di find me San Martino</h3>
<p>FIND ME as well</p>';
$regex = "/<(a|h[1-6])[^>]*>(?:[a-zA-Z0-9\s\'\-\.,]|(?:<(.*)>.*<\/\1>))*<\/(a|h[1-6])>(*SKIP)(*FAIL)|\b(" . preg_quote('find me') . ")\b(?=[^>]*(?:<|$))/i";
$text = preg_replace($regex, sprintf('<a href="%s">$4</a>', 'http://example.com'), $text);
Hope a fellow programmer can help me out :)
Fixed it by using the (for me) unknown $limit parameter .
$text = preg_replace($regex, sprintf('<a href="%s">$4</a>', 'http://example.com'), $text, $limit = 2);
