Vinko,

Are you sure that you compiled with php_mapscript_util.c revision 1.8? 
JF Doyon had the same extents problem as you with the test version of
php_mapscript_uitl.c that I Emailed both of you, but using revision 1.8
of php_mapscript_util.c (the latest in CVS) fixed it for him.

JF: Do you still get that extents problem?

For instance, to retrieve php_mapscript_util.c revision 1.7, you would
call:

  cd mapscript/php3
  cvs update -r 1.7 php_mapscript_util.c

Note that this is "sticky"... i.e. you'll be "stuck" with revision 1.7
forever, even next time you do a cvs update... to remove the sticky
flags and come back to the latest revision you'll have to use
  cvs update -A php_mapscript_util.c
