#46359 [Com]: getopt fails to recognize '?' as a short option

ID: 46359 Comment by: RQuadling at GMail dot com Reported By: johnston dot joshua at gmail dot com Status: Open Bug Type: Documentation problem Operating System: OS X 10.5.x and OpenSuSE PHP Version: Irrelevant New Comment: The parse_opts() function in php-src/ext/standard/basic_functions.c is responsible for this issue. Only 0-9, a-z and A-Z are acceptable characters for short options. It is odd that --? is supported if '?' is a long option. This 1 line change patch below should cover it.

It doesn't say anywhere in the manual about ? being a special character or which characters are accepted. It is common practice to use -h/-? as options that mean show the help I don't know if this is a documentation error or function error.
