WordPress plugin
“if your Plugin will be called “Fabulous Functionality”, you might call your PHP file fabfunc.php. Again, try to choose a unique name. People who install your Plugin will be putting this PHP file into the WordPress Plugin directory in their installation, wp-content/plugins/” – https://codex.wordpress.org/Writing_a_Plugin
- installed a new wordpress
- checked out wp-content/plugins/
- found hello.php, opened it, cloned it to ‘collapse.php’
- checked out installed plugins on wordpress and found collapse!
- activated it and it worked!
which means

Plugin Name: Hello Dolly
Plugin URI: http://wordpress.org/extend/plugins/hello-dolly/
Description: This is not just a plugin, it symbolizes the hope and enthusiasm of an entire generation summed up in two words sung most famously by Louis Armstrong: Hello, Dolly. When activated you will randomly see a lyric from <cite>Hello, Dolly</cite> in the upper right of your admin screen on every page.

/** These are the lyrics to Hello Dolly */
$lyrics = "Hello, Dolly
Well, hello, Dolly
It's so nice to have you back where you belong
You're lookin' swell, Dolly
I can tell, Dolly
You're still glowin', you're still crowin'
You're still goin' strong
We feel the room swayin'
While the band's playin'
One of your old favourite songs from way back when
So, take her wrap, fellas
Find her an empty lap, fellas
Dolly'll never go away again
Hello, Dolly
Well, hello, Dolly
It's so nice to have you back where you belong
You're lookin' swell, Dolly
I can tell, Dolly
You're still glowin', you're still crowin'
You're still goin' strong
We feel the room swayin'
While the band's playin'
One of your old favourite songs from way back when
Golly, gee, fellas
Find her a vacant knee, fellas
Dolly'll never go away
Dolly'll never go away
Dolly'll never go away again";
// Here we split it into lines
$lyrics = explode( "\n", $lyrics );
// And then randomly choose a line
return wptexturize( $lyrics[ mt_rand( 0, count( $lyrics ) - 1 ) ] );
}
// This just echoes the chosen line, we'll position it later
function hello_dolly() {

// Now we set that function up to execute when the admin_notices action is called

“add_action( ‘admin_notices’, ‘hello_dolly’ );”
admin_notices is a div on top of the dashboard and functions output goes up there!
Hooks
“For instance, before WordPress adds the title of a post to browser output, it first checks to see if any Plugin has registered a function for the “filter” hook called “the_title”. If so, the title text is passed in turn through each registered function, and the final result is what is printed. So, if your Plugin needs to add some information to the printed title, it can register a “the_title” filter function.” – https://codex.wordpress.org/Writing_a_Plugin
“You can sometimes accomplish the same goal with either an action or a filter. For example, if you want your plugin to change the text of a post, you might add an action function to publish_post (so the post is modified as it is saved to the database), or a filter function to the_content (so the post is modified as it is displayed in the browser screen).” – https://codex.wordpress.org/Plugin_API
