Application of Php-pear

Use of Php-pear
Recently to install Centreon, its system requires a lot of pear packages.
Checked, the original pear is an official PHP framework, probably similar to the official Python library and Ruby Gem bar?
A variety of PHP development tools can be installed under Linux with the pear install.

Install pear under Linux
Reference

$ wget Http://pear.php.net/go-pear.phar
$ PHP Go-pear.phar

But pear is not as convenient as Yum, I try to run:
Reference

Pear Install-o DB db_dataobject db_dataobject_formbuilder Validate MDB2 Date html_common html_quickform html_quickform_a Dvmultiselect html_table archive_tar auth_sasl console_getopt net_socket net_traceroute Net_Ping XML_RPC SOAP

-O indicates that only required dependencies are installed
The last error, said validate this package has no stable version.
Go to Pear official website to see, validate this package starts with the Alpha 0.0.2 version, until now the 0.8.4, actually has been the beta version ...

Workaround:
Use pear install-f channel://pear.php.net/validate-0.8.4
-F means forced installation
