I've run the above example on the latest 5.2 and 5.3 snapshots and am getting error messages warning about empty patterns similar to that in ereg() which is great. Thanks for making the change!

This is shown by setting the $regs argument and looking at the returned array which only contains one element which is bool(false). Reproduce code: --------------- <?php $unset_var = 10; unset ($unset_var); $inputs = array(NULL, null, false, FALSE, "", '', @$undefined_var, @$unset_var); $iterator = 1; foreach($inputs as $input) { if(@is_array($mb_regs)){ $mb_regs = ''; } echo "\n-- Iteration $iterator --\n"; echo "Without \$regs arg:\n"; var_dump( mb_ereg($input, 'hello, world') ); echo "With \$regs arg:\n"; var_dump(mb_ereg($input, 'hello, world', $mb_regs)); var_dump($mb_regs); $iterator++; }; ?> Expected result: ---------------- http://pastebin.com/f5f5c20ff Actual result: -------------- http://pastebin.com/f3f966bd0 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43994&edit=1
