Why you was using open SSL random bytes as initializing vector? That would not work. I removed your base64 and trim/strstr only by test. But would work with they added too.

You need understand that you need do a padding manipulation of the decrypted result because of your random initializing vector. First at all you need save in some place the output of openssl_random_bytes in order to see a specific byte combination.
