creating plugin headers

The plugin header is the only requirement for a plugin to function in WordPress. The plugin header is a PHP comment block located at the top of your primary plugin PHP file. This comment block tells WordPress that this is a valid WordPress plugin.
Write the following code in your Sample wordpress header plugin file myPlugin.php:

Plugin Name: myPlugin
Plugin URI: your url addredd
Description: my first wordpress plugin
WordPress admin interface
Version: 1.0
Author: you naem
Author URI: 
License: GPLv2

As you can see, the plugin header is straightforward. The only required line for WordPress to recognize your plugin is the plugin name, but it ’ s good practice to fill in the entire header as shown. The plugin will be shown at administration panel as :

You can activate this plugin from here but right now it does nothing.
