Which IDE/editor to choose for bulk changes (HTML/PHP)?

Question

PHP

Good afternoon!
I hope for help in the following question:
There is a site with 50+ subdomains.
Each subdomain is physically a separate site. At the same time, the physical structure on them matches 100%, and the content is somewhere around 90%. Everything is on the same server.
Files often require the same adjustments for all subdomains. Editing each subdomain in turn is not an option, of course.
I am quite satisfied with mass editing of files with regular replacements, but the problem is that all the files for this need to be opened first. Notepad++ does not allow you to do this automatically (i.e. you have to click a hundred times).
What could be the alternative? It is necessary that the editor supports bulk editing by regular expressions and makes it possible to open a set of files in a similar path for editing in one action (probably some command). No other features are required in principle (changes are usually simple).
Thank you!

Answer 1

Thanks to everyone for the answers, but I found the most suitable option myself.
"Replace in Path" function in PHPStorm.
It is clear that this is all a crutch, but this is the fastest and easiest way in my case.

Answer 2

You want to use the wrong tool to solve a problem.
Look towards static site generators, they will make your life much easier.
The generator can be installed locally, and only edits can be uploaded to the server.
There is a not bad Ruby generator - middleman. They were also on nodejs, but I did not work with them.
In theory, all this can be collected in gulp, the good thing is powerful, you just need to find a plugin that will arrange data from a json file in Html (similar to middleman). Well, to keep the data in one place, ala admin panel.

Answer 3

As an option, use git + something for auto-deploy.

Answer 4

It seems to me easier to make a constructor of such 50+ sites (or refactor specifically), and manage them from the admin panel than to find a solution in the IDE

Answer 5

Is the red-eyed solution suitable? bash script using sed (actual editor with regular expressions) + find (search for necessary files)

Answer 6

IMHO, crap. Editor of many files at once, regular expressions... Why?!
We take the site, make a complete edit to it, check its correctness.
We make a diff with the original and roll this patch on all copies.
