+### Target PHP version
+`composer.lock` is _always_ built for a particular version, by default the one it is generated (with `composer update`).
+
+If the PHP version used to generate the .lock isn't a widely available one (like PHP 8), a more common one should
+be locally specified in `composer.lock`:
+
+```json
+    "config": {
+        "platform": {
+            "php": "7.1.3",
+            "ext-something": "4.0"
+        }
+    }
+```
