There are some tutorials or blogs on the internet that are already describing “How to setup PEAR package on WAMP environment”, but after following each and every one of them I stumbled upon some errors and misconfiguration.

My configuration was done on WAMP 2.1 environment (with PHP 5.3.5)

1. step: You will need to setup “php.ini” file, the one from “php5.x.x” directory and not the one from “apache/bin”. Find the line:

;phar.require_hash = On

and change it to:

phar.require_hash = Off

Save the file and run “cmd” as Administrator.

2. step: go to PHP working directory in my case:

C:\wamp\bin\php\php5.3.5>

And type:

php -d phar.require_hash=0 PEAR/go-pear.phar

In next steps I used system (I used local at first but “pear” command was not working from command line even tho I set PATH variable) and watch for system paths (I chose “all” and added PEAR in directory name where applicable). Examples:

C:\wamp\bin\php\php5.3.5\PEAR
C:\wamp\bin\php\php5.3.5\PEAR\pear
C:\wamp\bin\php\php5.3.5\PEAR\www
C:\wamp\bin\php\php5.3.5\PEAR\cfg
C:\wamp\bin\php\php5.3.5\PEAR\docs
etc...

After installation is completed got to “php” folder under “PEAR” directory, find “PEAR_ENV.reg” and run it.

Try typing “pear” in command line if you are getting error (try to close current “cmd” and run new one):

'pear' is not recognized as an internal or external command,
operable program or batch file.

If the problem is still present try adding PEAR path manually in Environment Variables under “Path”:

;C:\wamp\bin\php\php5.3.5\PEAR

If “pear” is still not recognized as command try to reinstall PEAR from beginning.

If “pear” is working you should see next result after typing “pear” command:

C:\>pear

* Notice: if you get warnings about Structure_Graph do not worry we will get to that in a second.

3. step:

You can not follow step 3 if “pear” command is not working in your “cmd”!!!

Download [PEAR Structures] and extract its content to PEAR folder. Run “cmd” as Administrator and go to PEAR working directory Then run:

C:\wamp\bin\php\php5.3.5\PEAR>pear install -a Structures_Graph

If everything goes well you should see something like this:

downloading Structures_Graph-1.0.4.tgz ...
Starting to download Structures_Graph-1.0.4.tgz (30,318 bytes)
.........done: 30,318 bytes
install ok: channel://pear.php.net/Structures_Graph-1.0.4

After that upgrade PEAR with next command from same working directory:

C:\wamp\bin\php\php5.3.5\PEAR>pear upgrade PEAR

Well that is all to it. I tried to stress out where I had problem with setting up PEAR package. If you have any further question feel free to ask.
