As documented in https://wiki.php.net/rfc/use_global_elements, the engine (by default) does a local namespace lookup, then falls back to global namespace when first calling a global function referenced in namespaced code, unless that function is referenced via fully qualified name (FQN). By using the FQN, the actual symbol can be looked up at compile-time, both by the PHP engine and by static analysis tooling, allowing for compiler (in particular) optimizations to replace known hot-path functions with specialized opcodes. Sadly, no actual benchmark at hand: the improvements can be minimal or massive, depending on where this library is used (tight loops being most relevant).
