When I run: php jupyter-php-installer.phar install
it throws:
ERROR: Error while trying to download Jupyter-PHP dependencies with Composer.
when I run: php jupyter-php-installer.phar install -v
it says:
The Jupyter-PHP kernel has been successfully installed.
but there is no single trail of php kernel

Currently I'm able to install this using Jupyter-PHP-Installer, but would be nice to be able to install from this repo (to aid in development)

It would be nice to allow install per-notebook packages using composer, with automatically enabled autoloading for those per-notebook packages.

BUT, we have to confirm in first place if that's even possible:

• Confirm the possibility of attaching some metadata to notebook files, like directory paths, to store related vendor packages.
• In case it's possible, implement this nice feature.

It would be nice to add support to some PsySH commands:

• doc command: online documentation.
• ls command: for introspection.
• wtf command: errors introspection, for debugging.

It would be awesome to have a logo for this project ^_^ . Anyone around here with artistic aptitudes?

Some things should be better documented

• Jupyter install process. People without experience with Jupyter and/or Python would need easier to read and follow documentation than the official one. This should cover:
  • Required system packages list
  • Required PIP packages list
  • Step by step guide.
• PHP-ZMQ extension install guide.
• Install process without using the installer to aid development.

I have installed PHP on my Jupyter, but I cannot run it on the Jupyter notebook. Because PHP is not available to connect with Kernel.

Some kernels like IPython allow sending complex objects to the Jupyter Notebook, like tables, plots, or even interactive widgets. It would be nice to add those capabilities to the Jupyter-PHP kernel.

• tables and/or "dataframes" support.
• plots support.
• interactive plots support. Nice dream.

Hello;

After installing the PHP kernel, jupyter repeats the output returned by the PHP interpreter.
Please refer to the the attached image.

This issue happens on both an Ubuntu 16.04 and Fedoea 25 machines.

Anybody knows how to fix the error?

How can render and display HTML in output?
I try this codes:

header("Content-Type: text/html; charset=utf-8");
echo "Hi <b>world!</b>";

But have this in output:

Hi <b>world!</b>

In other words, what is the equivalent of the following python commands in Jupyter-PHP?

from IPython.core.display import display, HTML
display(HTML('<h1>Hello, world!</h1>'))

Jupyter Notebook shows a timeout message every time a Jupyter-PHP kernel is started. The timeout is related with the kerne_info_request request. In theory, the kernel is responding with a kernel_info_reply message, but for some reason this message is not arriving to (or not being accepted by) the kernel.

EDIT: This also causes missing syntax highlighting because Jupyter does not receive the needed info to use it in Pygments.

Would it be appropriate for this kernel to ignore a <?php line so that it can be passed a whole script?

Original issue report in Hydrogen: nteract/hydrogen#726

As @mmorton75 commented, other Jupyter kernels handle in a different way expression evaluations and data sent to stdout.

More info about this bug can be found in the discussion of the issue #17 .

Hii there,

I've tried using your notebook, but already at the first moment of using it, I found a little inconvenience:

I wonder if this could be solved soon?
Cheers

Thanks for great project.

Can use graphical chart and plot in the Jupyter-PHP be like matplotlib and Plotly library of jupyter python?
For example include Google Charts, chartjs, highcharts,... projects.

In other words, what is the equivalent of the following python commands in Jupyter-PHP?

import matplotlib.pyplot as plt
%matplotlib inline
plt.bar(range(0, 5), [10, 5, 13, 1, 20])

I am wondering if we can support melody : http://melody.sensiolabs.org/ .

May be an interesting feature if so.

It would be nice to use TravisCI and Scrutinizer to improve the project's quality.

• Travis CI Integration.
• Scrutinizer Integration.

php ./jupyter-php-installer.phar install -vvv

Hi there!

I want to use php in jupyterlab, but I encountered the following problem during the installation process. Does anyone know how to solve this?
Thank you very much.

Why do not syntax highlight the php codes?!
Is not this important?!

This is what all the other kernels seem to be doing. Could have options that redirect it to a file, but sending it by default also helps in log capture when running on the cloud (see also http://12factor.net/) which is useful for installs like paws.wmflabs.org (where I'm hoping to get this installed!)

We should ensure that Jupyter-PHP is compatible with PHP 7.

I have installed Jupyter-PHP everything is fine but i get this annoying error msg each keyword I type in my atom .

kernel dead.
oh no!

We should ensure that Jupyter-PHP is compatible with HHVM.

for ($i=1; $i<10; $i++) {
    echo $i;
}

this code output 9 lines in Jupyter instead of 1 line.

Running php ./jupyter-php-installer.phar install I get the following error:

ERROR: Error while trying to download Jupyter-PHP dependencies with Composer.

If I run the composer install with the composer.json from the repository it install the dependencies without any problem.
Any idea on how to make this work?
Thank you!
