I have multiple classes

class actors extends CI_Controller {
}    

class movies extends CI_Controller {
}

class producers extends CI_Controller {
}

class shows extends CI_Controller {
}

I want to capitalize the class name so the result is

class Actors extends CI_Controller {
}    

class Movies extends CI_Controller {
}

class Producers extends CI_Controller {
}

class Shows extends CI_Controller {
}

So i have to do find and replace with regex.

find class\s

replace class\s

How do i capitalize the class names?

It's not very clear what are you trying to do. Are you trying to execute this regex in IDE or are writing PHP code that will process PHP files and capitalize class names there? – p0358 Nov 18 '18 at 22:42
Use `preg_replace_callback`. See [this answer](https://stackoverflow.com/a/2638319/3832970). – Wiktor Stribiżew Nov 18 '18 at 22:42

Why can't you just rename them, or is this impossible? Edit: [might be relevant...](https://stackoverflow.com/q/19943995/1415724). @user892134 – Funk Forty Niner Nov 18 '18 at 22:43

Use the pattern `(class\s)([a-z])` and replace with `\1\U\2`. [Example](https://regex101.com/r/eHSC5M/1). – 41686d6564 stands w. Palestine Nov 18 '18 at 22:45
@AhmedAbdelhameed Thanks got it working – user892134 Nov 18 '18 at 22:46
Or `class\s+\K[a-z]` => `\u$0`, `\b(class\s+)([a-z])` => `$1\u$2`, etc. I linked to the [answer](https://stackoverflow.com/a/37563098/3832970) that will help you master these kinds of replacements. – Wiktor Stribiżew Nov 18 '18 at 22:52
