Install PHP kernel under Jupyter Notebook
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-configProblem 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

What are the best practices for writing clean and maintainable PHP code?
Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
