Small wordpress mod to integrate php script

Need Split Test Accelerator to work within a wordpress post. ## Deliverables Hi. I'm trying to add php code to a wordpress post so that I can split test headlines. The wordpress plugin "safeIncludes" is supposed to work with my split test program. And I can get the "safeIncludes" plugin to post other php code in my wordpress posts. I can also get my split test program to work in static pages. Here is the code I'm need to work within the "safeIncludes" wordpress post: <?php $id=2; include('/home/forexsca/public_html/sta/[login to view URL]');?> <?php if ($f[1]==1){echo $code[1];}?> <?php if ($f[1]==2){echo $code[2];}?> Thanks.
