Anyone got actual PROOF that macros are more efficient in an
interpreted language? Claims that <language construct x> is
more efficient without specifying the language are almost always
false.

Let's see you implement the equivalent of the C macros:
#define LENGTH (
#define FEET ) * 12.0 + (
#define INCHES )
used as:
LENGTH 6 FEET 3 INCHES
in a PHP function. Of course, abusing C macros like that should carry
the death penalty.
