Find and replace strings within your text files.
Originally found this code here: https://gist.github.com/twhitney11/3803245
and decided to update it to work with PHP 8.
Tested on PHP versions 8.0 to 8.4
It now allows the file-types-to-search to be input on the command line.
You can change $limit_to_dirs and $dirs_to_skip to suit your particular needs.
