Absolutely, but it's not an actual problem, because:

The Zend Engine License (available in Zend/LICENSE within the PHP source
tree) explicitly deals with this problem. To quote section 4 of said
licence:

4. Zend Technologies Ltd. may publish revised and/or new versions
of the license from time to time. Each version will be given a
distinguishing version number.
Once covered code has been published under a particular version
of the license, you may always continue to use it under the
terms of that version. You may also choose to use such covered
code under the terms of any subsequent version of the license
published by Zend Technologies Ltd. No one other than Zend
Technologies Ltd. has the right to modify the terms applicable
to covered code created under this License.

The important bit is that covered code can always be used under the
version of the Zend Engine License. Even in the incredibly unlikely
situation that Zend were to get bought out and development of the Zend
Engine was closed, the most recent version of the Zend Engine included in
the PHP source tree would remain open source, and I dare say that
development would continue on that open source version of the Zend Engine
regardless: much of the work that occurs on the engine comes from
developers who aren't employed by Zend anyway.

tl;dr: Can't happen. Relax.
