phpsh is an interactive shell for php that features readline history, tab completion, quick access to documentation. It was developed at Facebook and ironically, is written mostly in python. This article explains how you can install/use it on a Debian Etch system.

This document comes without warranty of any kind! I do not issue any guarantee that this will work for you!

1 Installing phpsh

phpsh depends on PHP (4 or 5, 5 is recommended) and Python 2.4+, therefore we install PHP5 and Python as follows:

apt-get install php5-cli python

Afterwards we download and uncompress phpsh as follows:

wget http://www.phpsh.org/phpsh-latest.tgz
tar xvfz phpsh-latest.tgz

This creates the directory phpsh with the phpsh executable. Before we can run phpsh, we must make it executable:

cd phpsh
chmod 755 phpsh

2 Using phpsh

Now we can start the PHP shell simply by running

./phpsh

http://www.phpsh.org/readme.php shows how you can use the PHP shell. You can use tab to autocomplete function names, global variable names, constants, classes, and interfaces, and you can use the arrow keys to browse the command history. The equal sign at the beginning of a line will return the value of an expression.

Type

q

to leave the PHP shell.

Here's a sample output:

server1:~/phpsh# ./phpsh
I can't find a tags file for you.  To enable tab completion in phpsh,
go to the root directory of your php code and run 'ctags -R',
(or whatever the analagous command is with your version of ctags,)
then run phpsh from that directory or a subdirectory of that directory.
Commandline: php -q /root/phpsh/phpsh.php
