I have recently been strongly attracted by Jupyter Notebook, an interactive notebook. Then after trying out its own Python kernel, I felt very good about this application as a whole, so I searched for other kernels it supports, including Jupyter Kernels.
I will introduce below how to install the PHP kernel under this application.
Installation steps
Install PHP kernel Jupyter-PHP
Environment requirements
1.PHP > ;= 7.0
2.Jupyter Notebook has been installed
3.Operation on Mac
Steps
1.Install Composer globally
$ curl -sS https://getcomposer.org/installer | php $ mv composer.phar /usr/local/bin/composer
2. Install the PHP-ZMQ extension
(1) Download and compile
$ git clone git://github.com/mkoppanen/php-zmq.git $ cd php-zmq $ phpize && ./configure $ make && make install
(2) Modify the configuration
Modify the php.ini configuration and add `extension=/path/modules/zmq.so`
3. Downloadjupyter-php-installer.phar
4.Execute phar installation program
$ php jupyter-php-installer.phar install
5. The installation is successful, and the Jupyter-PHP kernel has been successfully installed.
Problems encountered and solved
Problem 1:
Compile PHP-ZMQ without autoconf and pkg-config
Solution:
$ brew install autoconf $ brew install pkg-config
Problem 2:
No php.ini on Mac
Solution:
$ sudo cp /etc/php.ini.default /etc/php.ini
Question 3:
The compiled extension zmq.so cannot be moved to the PHP default extension path /usr/lib/php/extensions/no-debug-non- zts-20160303/
Solution:
Because macOS System Integrity Protection (SIP) will prevent you from moving zmq.so to the default path, and I don’t want to turn off SIP. So the solution is to introduce extensions to write absolute paths
extension=/path/modules/zmq.so
Problem 4:
Use PHP kernel and print to print double output
Solution:
In fact, it is caused by the indistinguishable output between the printed value and the return value, and the author has not solved it yet. View issues
