Use of $_SERVER variables in custom plugin

Question

In my Joomla application, I have functionality where I use server variables, like request_uri and query parameters for parsing url string.

This function is used in many modules. So, I wanted to implement the same functionality by using a custom plugin, following Joomla tutorial.

My question is whether using a plugin in this case is appropriate.
And can we use server objects in a plugin class?

If yes, how to use this plugin in my other modules and components.

Any detailed answers are appreciated.

You could create your own library with the functionality you want to re-use in all your extensions and load it each time with JLoader.

The $_SERVER is a SUPERGLOBAL variable and can be accessed anytime from everywhere.

Since you are working with Joomla, you may want to use what Joomla has to offer, so have a look at JURI

Job could be done with a plugin as well. For example you could create a system plugin and in your plugin's classes create public methods.

Accessing your plugin from your modules:

$myPluginFramework = new MyPluginFramework();

$myPluginFramework->myRequestUri();

Note that the plugin must be enabled in order to be able to create a new object of your plugin class. You probably have to consider any checks for if the class exists

if (class_exists('MyPluginFramework')) {
    $myPluginFramework = new MyPluginFramework();
    $myPluginFramework->myRequestUri();
    ...
}
