How to programm in PHP your phone or android tablet
First you will need to install Termux.
In Termux you run the following:
First if you haven't already, make it possible to access the phone drive from termux. This is optional.
termux-setup-storage ls storage ls storage/shared
If you run those three commands, you will see the contents of your android phone. The folders in showing up in the second commands are shortcuts. The folders under storage/shared is the topmost directory on your phone.
Install PHP and libraries:
pkg upgrade pkg install php openssl composer sqlite libxml2 libxslt git
You can now run PHP programs by typing "php index.php".
Let's get started with PHP Router:
git clone https://github.com/Largo/phprouter.git cd phprouter php -S 127.0.0.1:8080 routes.php
Open 127.0.0.1:8080 in the phone browser to see PHP router in action. You should see the word INDEX on the screen. Check out the code to learn more about PHPRouter. Here is my Fork and here is the documentation.
You can of course also install laravel, symfony or anything else! Yes, it's possible to programm in laravel on your android smartphone or android tablet! Or not use any framework!
You will probably want a text editor on your phone. You can either run one inside linux on termux or you use an android app and select the folder and file in the app. For blog posts, I use iA Writer, but there are editors like ACode which look promising. Consider using micro, nano, emacs or vim because you can use them on all other systems too.
You might be easier to install code server on a VPS to use vscode on android through a server. Gitpod/Github Codespaces is another option. Stay tuned for my article on that!
