PEAR (short for PHP Extension and Application Repository) is a framework and distribution system for reusable PHP components. In includes many useful tools and components that can be easily downloaded and installed by using PEAR package manager. This post describes how to install and configure PEAR package manager and then how to use it to install a PEAR package. An example PEAR package used in this post is phploc, whichAis a tool for measuring the size of PHP projects.

Start by installing PHP on Windows by using one of the following methods:

Now open an elevated command line prompt and go to the directory where PHP was installed. For example if PHP 5.3 was installed with Web PI 3.0 then the directory path will be:

  • %ProgramFiles%\PHP\v53\ - when PHP is installed for IIS
  • %ProgramFiles%\IIS Express\PHP\v53 - when PHP is installed for IIS Express

While in that directory run the go-pear.bat command. If you intend on having multiple versions of PHP installed on the same machine then make sure to answer aolocala on the first question asked by go-pear.bat:

C:\Program Files\PHP\v5.3go-pear.bat Are you installing a system-wide PEAR or a local copy? (system|local) [system] : local Please confirm local copy by typing 'yes' : yes Below is a suggested file layout for your new PEAR installation.A To change individual locations, type the number in front of the directory.A Type 'all' to change all of them or simply press Enter to accept these locations. 1. Installation base ($prefix)AAAAAAAAAAAAAAAAAA : C:\Program Files\PHP\v5.3 2. Temporary directory for processingAAAAAAAAAAA : C:\Program Files\PHP\v5.3\tmp 3. Temporary directory for downloadsAAAAAAAAAAAA : C:\Program Files\PHP\v5.3\tmp 4. Binaries directoryAAAAAAAAAAAAAAAAAAAAAAAAAAA : C:\Program Files\PHP\v5.3 5.

Continue following the prompts to complete the installation process. During the installation you may seeAa warning similar to the one shown below:

****************************************************************************** WARNING!A The include_path defined in the currently used php.ini does not contain the PEAR PHP directory you just specified: If the specified directory is also not in the include_path used by your scripts, you will have problems getting any PEAR packages working. Would you like to alter php.ini ? [Y/n] : y

Make sure to say yes [y]Ato the question about altering php.ini so that include_path directive is updated to the correct PEAR PHP directorty

After that you may also get a warning about out-of-date version of PEAR package manager:

** WARNING! Old version found at C:\Program Files\PHP\v5.3, please remove it or be sure to use the new c:\program files\php\v5.3\pear.bat command

If you see that then after the go-pear.bat has finished its work, run the following command to upgrade the PEAR package manager:

C:\Program Files\PHP\v5.3pear upgrade pear downloading PEAR-1.9.1.tgz ... Starting to download PEAR-1.9.1.tgz (293,587 bytes) .................done: 293,587 bytes downloading Archive_Tar-1.3.7.tgz ...
