The radius is the package which is based on the libradius (Remote Authentication Dial In User Service) of FreeBSD. It allows customers to identify and make representations through network applications on remote servers. This PECL extension supports any protocol Radius Authentication for full identification and Radius Accounting. This package is available for Unix (tested on FreeBSD and Linux) but also for Windows. These functions are available in the standard PHP module, which is always available.

The radius is an extension of PECL which is not bundled with PHP. The following are the Predefined Constants :

• RADIUS_ACCESS_REQUEST ()
• RADIUS_ACCESS_ACCEPT ()
• RADIUS_ACCESS_REJECT ()
• RADIUS_ACCOUNTING_REQUEST ()
• RADIUS_ACCOUNTING_RESPONSE ()
• RADIUS_USER_NAME (string)

I have provided you more predefined constants that can be useful for you. These constants are defined by this extension, and are only available when the extension has been compiled into PHP or dynamically loaded at runtime. The following are the predefined constants :

• RADIUS_NAS_IP_ADDRESS (string)
• RADIUS_NAS_PORT (integer)
• RADIUS_SERVICE_TYPE (integer)
• RADIUS_FRAMED_IP_ADDRESS (string)
• RADIUS_FRAMED_IP_NETMASK (string)
• RADIUS_FRAMED_ROUTING (integer)
• RADIUS_FILTER_ID (string)

You should follow the steps mentioned below while using the Radius Service :

1. First, you will have to retrieve a radius resource
2. Then configure the library
3. After that create the request
4. Add the attributes
5. Send request
6. After sending retrieve attributes
7. Lastly close the radius resource (optional)
