Test script: --------------- <?php mb_ereg_search_init('foo'); var_dump(mb_ereg_search('\A')); var_dump(mb_ereg_search_getpos()); var_dump(mb_ereg_search('\s*')); var_dump(mb_ereg_search_getpos()); var_dump(mb_ereg_search('\w+')); var_dump(mb_ereg_search_getpos()); var_dump(mb_ereg_search_getregs()); var_dump(mb_ereg_search('\s*')); var_dump(mb_ereg_search_getpos()); var_dump(mb_ereg_search('\Z')); var_dump(mb_ereg_search_getpos()); Expected result: ---------------- bool(true) int(0) bool(true) int(0) bool(true) int(3) array(1) { [0]=> string(1) "foo" } bool(true) int(3) bool(true) int(3) Actual result: -------------- // warnings suppressed, see bug #72691 bool(true) int(1) bool(true) int(2) bool(true) int(3) array(1) { [0]=> string(1) "o" } bool(true) int(4) bool(false) int(3) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72693&edit=1
