php storm cannot find class ZMQContext
Hi,
 I bind php with zeromq according to website zeromq.org.(I download dll files from PECL). 
Then I added dependency with composer React/zmq(version 0.3.0). 

According to tutorial I wanted to create new object f.e. $cronn=new ZMQContext(); But phpstorm don't know this class. I don't know where is a problem. 
I'm using win 8 64bit and PHP version is 5.5.15 . So I downloaded dll file for php 5.5 x86 (because in phpinfo() I found only x86) .
I found other classes like Context,Buffer,BufferTest... but there is no ZMQContext.

Where is the problem ?
Thanks for answer
