This PR was submitted for the 4.2 branch but it was merged into the 3.4 branch instead (closes #11200). Discussion ---------- Update dotenv.rst it seems standard practice is to no longer use `getenv()` due to it not being thread safe. symfony/symfony@21a909a Updated the docs to remove reference to that function. Would we want to go so far as to add a note to **not** use `getenv()`? Commits ------- 5be35bf Update dotenv.rst
