How to Install PEAR in a WAMP

PEAR could be the most important add-on library for PHP developers. Here is an example to install PEAR in a WampServer:

1. Create a directory to serve PEAR.

In this case, we choose C:\wamp\bin\php\pear for our PEAR.

2. Download and save go-pear.phar from the official website.

The file can be downloaded from http://pear.php.net/go-pear.phar

3. Start cmd and cd to the directory that go-pear.phar resides in.
C:\Documents and Settings\Administrator>cd C:\wamp\bin\php\pear
4. Use php utility to execute the phar file.

Start to install PEAR.

C:\wamp\bin\php\pear>C:\wamp\bin\php\php5.4.3\php go-pear.phar

Enter "local" and then "yes"

Are you installing a system-wide PEAR or a local copy?
(system|local) [system] : local
Please confirm local copy by typing 'yes' : yes

Only item 12 needs to be specified, please enter the path of php.exe.

Below is a suggested file layout for your new PEAR installation.  To
change individual locations, type the number in front of the
directory.  Type 'all' to change all of them or simply press Enter to
accept these locations.

 1. Installation base ($prefix)                   : C:\wamp\bin\php\pear
 2. Temporary directory for processing            : C:\wamp\bin\php\pear\tmp
 3. Temporary directory for downloads             : C:\wamp\bin\php\pear\tmp
 4. Binaries directory                            : C:\wamp\bin\php\pear
 5. PHP code directory ($php_dir)                 : C:\wamp\bin\php\pear\pear
 6. Documentation directory                       : C:\wamp\bin\php\pear\docs
 7. Data directory                                : C:\wamp\bin\php\pear\data

 9. Public Web Files directory                    : C:\wamp\bin\php\pear\www
10. Tests directory                               : C:\wamp\bin\php\pear\tests
11. Name of configuration file                    : C:\wamp\bin\php\pear\pear.ini
12. Path to CLI php.exe                           :

******************************************************************************
WARNING!  The include_path defined in the currently used php.ini does not
contain the PEAR PHP directory you just specified:
<C:\wamp\bin\php\pear\pear>
If the specified directory is also not in the include_path used by
your scripts, you will have problems getting any PEAR packages working.

PEAR will modify the interpreter php.ini in the following location. But for a WAMP server, the effective one is in C:\wamp\bin\apache\apache2.2.22\bin, you can append a snippet to apache\php.ini after the installer modifies the interpreter php.ini.

Would you like to alter php.ini <C:\wamp\bin\php\php5.4.3\php.ini>? [Y/n] : Y

php.ini <C:\wamp\bin\php\php5.4.3php.ini> include_path updated.

Current include path           : .;C:\php\pear
Configured directory           : C:\wamp\bin\php\pear\pear
Currently used php.ini (guess) : C:\wamp\bin\php\php5.4.3\php.ini
Press Enter to continue:

** WARNING! Old version found at C:\wamp\bin\php\pear, please remove it or be sure to use the new c:
wamp\bin\php\pear\pear.bat command

The 'pear' command is now at your service at c:\wamp\bin\php\pear\pear.bat

** The 'pear' command is not currently in your PATH, so you need to
** use 'c:\wamp\bin\php\pear\pear.bat' until you have added
** 'C:\wamp\bin\php\pear' to your PATH environment variable.

Run it without parameters to see the available actions, try 'pear list'
to see what packages are installed, or 'pear help' for help.

Thanks for using go-pear!


C:\wamp\bin\php\pear>
5. Append a snippet to apache php.ini which is in C:\wamp\bin\apache\apache2.2.22\bin
;***** Added by go-pear
include_path=".;C:\wamp\bin\php\pear\pear"
;*****
6. C:\wamp\bin\php\pear should be added to PATH environmental variable.
7. Restart the WAMP server

Now, let's test PEAR utility.

Install a package MDB2.
