Add code before the third h3 tag

[walid]

I am using wordpress an I am trying to dynamically add an ad to my content. I want the ad to show before the third h2 tag.

How can I do this in php?

I need something like:

if third h2 tag,then echo "ads" before that h2

I'm not familiar with the Word Press environment, but I would make these recommendations:

Don't go backwards. Code isn't going to hit the brakes and jump into reverse.

Give the h2 a CLASS

<h2 class="ad_space">

Then search for ad_space.

You can do an online search for PHP string functions and determine how you want to locate that sub-string (maybe use stripos to obtain a true/false)
