Is there an editor with dev code capability?

Question

PHP

There is an editor that can save (or similar actions) 2 types of code.
The first is general, and the second is general + additional.
The bottom line is that I want to make 2 versions of one script and in one of them each step will be logged.
For example:

*$log = 'Приветствие';

echo 'Hello, world!';

*var_dump(
*    $log
*);

Anything that has a "*" in front of the string will not get into one of the script versions.

Answer 1

git with branches

Answer 2

You should read about logging levels .

Answer 3

define ("debug", true);
function debug($var, $comment){
     if(debug){
         echo "// $comment //\n";
         // do debug stuff
     }
     return;
}

In production, set to false -> profit!
Or, if you read your answer about the absence of anything in one version - git with separate branches .
