Optimizing your code using code profiler and code analyzer

You need to install Netbeans in order to use this plugin. Here are the steps you need to follow:

1) Open NetBeans then select option from menu bar Tools > Plugin. Then search plug-in name "phpcsmd" in the available plug-in tab and install it from there.

2) Now open the terminal and be there as the super user by typing command "sudo su".

3) Install PEAR library (if it is not installed) into your system by running following commands into your terminal

b) php go-pear.phar

As we need this for the installation of further addons.

4) Then run the command

"pear config-set auto_discover 1"

This will be used to set auto discover the path "true" for the required plug-ins. So they get install to the desired location automatically.

5) Then run below command to install PHP code sniffer.

"pear install --alldeps pear/PHP_CodeSniffer"

6) Now to install the PHP Mess Detector by running following command

"pear install --alldeps phpmd/PHP_PMD"

If you get the error like "invalid package name/package file "phpmd/PHP_PMD"" while installing this module. You need to use this "pear channel-discover pear.phpmd.org" command to get rid of this error. After this command you can run the above command again to install Mess detector.

7) Now to install the PHP Depend by running following command

"pear install --alldeps pdepend/PHP_Depend"

8) Now install the PHP Copy Paste Detector by running following command

"pear install --alldeps phpunit/phpcpd"

9) Then run the command
