How can I replace the obsolete split PHP command with explode in a folder structure with many files?

In the meantime, I figured it out myself.

find . -iname '*.php' -type f -exec grep -l -m 1 -P '[<][?]' {} \; | xargs -r grep -l -m 1 --null -P '[^_.]split[\s]*[(]' | sudo xargs -0 -r perl -pi -e 's/([^_.])split([\s]*[(])/$1explode$2/g'
  1. Get PHP files (case-insensitive).
  2. Check if <? is inside.
  3. Check if split( is inside.
  4. Replace split( with explode(.

For 3 and 4: _split( (preg_split) and .split( (Javascript in my case) won't be replaced.

Tested on Ubuntu 18.04.

    Refactoring code is generally best left to IDEs

    I upvoted your comment. But finally understanding all this find, grep, xargs, sed/perl, pipe and regex stuff makes me happy. :) It was a long run. :)
