Reproduce code: --------------- function some_func() { echo "some_func() was called!\n"; return 'bar'; } echo str_replace('foo', some_func(), "aaaaa"); Expected result: ---------------- aaaa Actual result: -------------- some_func() was called! aaaa ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43642&edit=1
