What regex to use in php?

Question

React

Good afternoon dear experts! I would like to ask you a question about a regular expression.
I do not quite understand how to implement the removal of characters I do not need.
I have a code:
$str = substr($filename, strlen('Subject(*)'));
I have files:
1. Subject(Fwd_ CASTORLAND Price list September 2016)_Price Castorland September-2016!!!NEW+Darts!!!1.xlsx
2. Subject(Fwd_ Atberg 98, price)_Price dated 12.09.16.xls
....
I write something like strlen('Subject(*)'), but only the first parenthesis and the first letter are removed. How can I remove everything inside the brackets along with Subject.
Example: Before
: Subject(Fwd_ Atberg 98, price)_Price from 12.09.16.xls Now
: Price from 12.09.16.xls
And so that, even after the bracket (the last one), the symbol _
is deleted Thank you very much for your help!

Answer 1

Are you using webpack?
The error is most likely in the wrong connection of the file with the code (bundle.js usually). Such an error usually looks like this in the console . More details here .
I can’t answer the question more precisely without the server startup code, and the webpac-dev-server code and webpack-config files may also come in handy.

Answer 2

Good afternoon.
As far as I'm concerned, here's what might work:

preg_replace('/Subject\(.*\)_/i', '', $str); // где $str - имя файла
