[TYPO3] Some different headers

[Fred]

Hi,
I'm building a site with typo3 4.0.1.
I used the template object browser to modify my headers like that :

lib.stdheader.stdWrap.dataWrap = <div class="csc-header">|</div>
lib.stdheader.10.1.fontTag = <h1>|</h1>

My problem, now, is I'd like to develop this technic a bit more, to 
insert a php script inside this header, for exemple, and moreover I'd 
like to know if (and how) it's possible to design several headers 
depending on the "type" selector.

Thanks if you can help me.
