PHP Packages Using the PEAR Installer

PHP Packages



Using the PEAR Installer

Problem

You want to use the PEAR installer, pyrus. This allows you to install new packages, upgrade, and get information about your existing PEAR packages.

Solution

Install Pyrus.

To execute a command, type the command name as the first argument on the command line:

       % php pyrus.phar command

Discussion

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 (akaa phar). So, all that’s necessary is to download the file.

Then use PHP to run it:

       % 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:

       % php pyrus.phar list-packages
       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. 

Table  Common PEAR installer commands

Command name   Shortcut       Description                                                                                                              
install                         i                   Download and install packages
upgrade                     up                Upgrade installed packages
uninstall                    un                Remove installed packages
list-packages             l                   List installed packages
list-upgrades             lu                List all available upgrades for installed packages
channel-discover     di                 Initialize an alternate PEAR Channel from its server

search                         s                  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:

       % 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:

       % php pyrus.phar get
       Pyrus version 2.0.0a4 SHA-1: 72271D92C3AA1FA96DF9606CD538868544609A52
