https://github.com/php/php-src/commit/f00d1c72b4dbaf3532569d20efc1da7c408605d6 The above patch optimizes calls to gettype() into an opcode, however the strings returned for closed resources has changed relative to 7.1 and earlier. The newer output is objectively better, but it's technically a BC break. Was this intentional, and are we fine letting this change stand? -Sara
