Hi Milan:
I was banging my head against the Sabre wall as well. I'd successfully used cURL for another web service, and figured that's what would work for Sabre as well. I quickly found that wasn't going to work here.
Luckily I did find a blog post which used a different approach, and it worked! Although many people had commented asking for a sample with SessionCreateRQ, the author had not provided it. So I wrote my own blog post with a complete example, plus a few minor tweaks to the original class. You can find it all at:
Sabre Web Services in PHP[

I hope this helps.
