Actually, when using a custom completion function with readline_completion_function(), if this custom completion function does not find any match, it falls back to the default filename completion.

In order to prevent this behaviour, the C API of readline provides a variable named "rl_attempted_completion_over". Defining this variable to a non-zero value disables the uses of the default filename completion.

This variable is not exposed to PHP and the filename completion cannot be bypassed. The provided patch exposes this variable to PHP, and allows to use readline_info("attempted_completion_over", 1) in the PHP completion function to prevent default filename completion to occurs.

There is a bug report but it s closed since 2005

Another bug report for this with a patch which does the job but in a wrong way, imo.
