Using the PEAR Installer in PHP

InfinityCoder December 27, 2016

You want to use the PEAR installer, pyrus. This allows you to install new packages, upgrade, and get information about your existing PEAR packages.
To execute a command, type the command name as the first argument on the command line:

1
% php pyrus.phar command

Pyrus is a tool to manage PEAR packages. It’s not bundled with PHP, so you need to install it yourself. Fortunately, Pyrus is distributed as a self-contained PHP Archive (aka a phar). So, all that’s necessary is to download the file.

 

Then use PHP to run it:

1

% php pyrus.phar --version
 
Pyrus version 2.0.0a4 SHA-1: 72271D92C3AA1FA96DF9606CD538868544609A52
Using PEAR installation found at /Users/rasmus/lib
php pyrus.phar version 2.0.0a4.

Here’s how to list all installed PEAR packages with the list-packages command:

Pyrus version 2.0.0a4 SHA-1: 72271D92C3AA1FA96DF9606CD538868544609A52
Using PEAR installation found at /Users/rasmus/lib
Listing installed packages [/Users/rasmus/lib]:
[channel pecl.php.net]:
(no packages installed in channel pecl.php.net)
[channel doc.php.net]:
(no packages installed in channel doc.php.net)
[channel __uri]:
(no packages installed in channel __uri)
[channel pear.php.net]:
Archive_Tar 1.3.7 stable
Console_Getopt 1.3.0 stable
PEAR 1.9.4 stable
Structures_Graph 1.0.4 stable
XML_Util 1.2.1 stable

For a list of all valid PEAR commands, use help. pyrus has commands for both using and developing PEAR packages; as a result, there are many commands that you may not need.

The package command, for example, creates a new PEAR package. If you only run other people’s packages, you can safely ignore this command. See Table 27-2 for a list of frequently used commands.
Table 27-2. Common PEAR installer commands

Command name Shortcut Description
install

upgrade

uninstall

list-packages

list-upgrades

channel-discover

list-channels

search

i

up

un

l

lu

di

lc

s

Download and install packages

Upgrade installed packages

Remove installed packages

List installed packages

List all available upgrades for installed packages

Initialize an alternate PEAR Channel from its server

List all locally configured PEAR Channels

Search for packages

To find where your PEAR packages are located, run the get php_dir PEAR command.
You can check the value of the include_path by calling ini_get(‘include_path’) from within PHP or by looking at your php.ini file.

If you can’t alter php.ini because you’re in a shared hosting environment, add the directory to the include_path at the top of your script before including any PEAR files.

You can configure Pyrus settings using:

1
% php pyrus.phar set setting value

Here setting is the name of the parameter to modify and value is the new value. To see all your current settings, use the get command:
