ZeroMQ with php7 in ubuntu not working

问题:

I have upgraded php5.6 to php7, but zeromq extension makes a lot of problems. Where can I download the correct zmq.so file for php7? None of the official sites offer a version for php7 that works (I'm using apache2.4).

I've followed along the following tutorial: How to install ZeroMQ.

The step "Installing ZeroMQ" is working fine, but the second step "Installing the PHP binding" is failing when I execute the command "make" with the following error:

"/home/puser/zeromq-4.1.4/php-zmq/zmq.c:2740:2: error: too many arguments to 
function 'zend_register_internal_class_ex' php_zmq_device_exception_sc_entry = 
zend_register_internal_class_ex(&ce_device_exception, php_zmq_exception_sc_entry, 
"ZMQException" TSRMLS_CC)  ^ In file included from /usr/include/php/20151012/main/php.h:40:

zend_class_entry *zend_register_internal_class_ex(zend_class_entry *class_entry, 
zend_class_entry *parent_ce);"

When using php 5.6, this error does not appear. How to fix this?

Edit: I 've found that ZeroMQ is currently "not working" with php7 from this post: ZeroMQ installation. Is there any workaround?

回答1:

There is a beta version available via PECL that you can install, I have been working with it without any issues.

sudo apt-get install php-pear
pecl install zmq-beta

If you get an error during install then you are most likely missing some dependencies

sudo apt-get install php7.0-dev libzmq-dev pkg-config

For MacOS, you can replace apt-get with brew and it should also work.

In newer versions of Ubuntu/Debian you can now do

sudo apt-get install php-zmq

Which is recommended over the previous method because it uses a newer version of the underlying ZeroMQ library and takes care of enabling the extension for you.

回答2:

the zmq PHP extension has not yet been ported to PHP7. work is in progress : https://github.com/mkoppanen/php-zmq/issues/155

update: there is a new release with PHP7 : https://pecl.php.net/package/zmq/1.1.3

I just published all the steps to install zmq and php-zmq on Debian or Ubuntu 16.04 with php7: Install ZMQ and php-zmq extension on Debian or Ubuntu
