# Configuring PEAR on Windows

[<span class="caps">PEAR</span>](http://pear.php.net/) is the <span class="caps">PHP</span> Extension and Application Repository. Applications written in <span class="caps">PHP</span> often include references to external libraries and <span class="caps">PEAR</span> is a way to manage these. On Windows if <span class="caps">PEAR</span> hasn’t already been configured log in to the server and run go-pear.bat in the <span class="caps">PHP</span> directory (C:\\php in this case). This adds the <span class="caps">PEAR</span> settings to php.ini:

```
<br></br>include_path=“.;C:\php\pear”<br></br>
```

  
It also creates “pear.bat” which can be used to search for and install components. For instance:```
pear search Requestpear install HTTP_Request
```

If you use the Apache Web Server after running go-pear.bat it’s necessary to restart Apache (as with any other changes to php.ini).
