+Subject: [PATCH] Fix regression introduced by fixing bug 81726
+
+When a tar phar is created, `phar_open_from_fp()` is also called, but
+since the file has just been created, none of the format checks can
+succeed, so we continue to loop, but must not check again for the
+format. Therefore, we bring back the old `test` variable.
+
+Closes GH-9620.
+
+(cherry picked from commit 432bf196d59bcb661fcf9cb7029cea9b43f490af)
