PHP MapScript doesn't try to detect whether PHP was compiled in debug or
non-debug mode.  It just assumes non-debug all the time.  If you would
like this to change eventually then please file a enhancement bug in
bugzilla.

In the meantime, you'll find in php_mapscript.c the following lines
(around line 250):

#ifdef PHP4
#define ZEND_DEBUG 0
#endif

Try setting ZEND_DEBUG to 1 and recompile.  I haven't tried this
recently but it may do what you want.
