Registers a completion function
(PHP 4, PHP 5)
Code Examples / Notes » readline_completion_php
This function can simply return an array of all possible matches (regardless of the current user intput) and readline will handle the matching itself. This is likely to be much faster than attempting to handle partial matches in PHP.
It seems that the registered function can accept 2 parameters, the first being the partial string, the second a number that when equal to zero indicates that the tab was hit on the first argument on the input. Otherwise it looks like the position within the string is returned.
This is neccessary information for processing shell command line input.
