+### 6.4. Operator's placement
+
+A statement that includes an operator MAY be split across multiple lines, where
+each subsequent line is indented once. When doing so, the operator MUST be
+placed at the beginning of the new line; ternaries MUST occupy 3 lines, never 2.
+
+For example:
+
+```php
+<?php
+
+$variable1 = $ternaryOperatorExpr
+    ? 'fizz'
+    : 'buzz';
+
+$variable2 = $possibleNullableExpr
+    ?? 'fallback';
+
+$variable3 = $elvisExpr
+    ?: 'qix';
