Description:
------------
When running PHP interactive interpreter with:
    
    php -a
    
"Delete" button doesn't work (produces `~` instead), jumping over words with 
"Ctrl"+"Left Arrow" and "Ctrl"+"Right Arrow" doesn't work either (`;5D` and 
`;5C`, respectively). It annoys me a lot - I use `php -a` every day. 
Worth noting, that other interpreters (irb, ipython, etc.) work good.

The problem occurs in each distro I tried - (K)Ubuntu (PHP 5.4.9-4ubuntu2.1 (cli) 
(built: Jun 11 2013 13:10:01)), Fedora (PHP 5.3.3 (cli) (built: Nov 29 2012 
04:12:23)), RHEL (PHP 5.3.3 (cli) (built: Nov 29 2012 04:12:23)). Works good on 
Mac though.

Expected result:
----------------
Ctrl+arrows should move the cursor by words, delete should delete current 
character.

Actual result:
--------------
Ctrl+left arrow produces ;5D
Ctrl+right arrow produces ;5C
Delete produces ~

Not a PHP bug. Configure .editrc (for libedit) or .inputrc (for readline). For 
instance, I see that ubuntu compiles PHP against libedit, so for instance to 
have DEL to work you could edit your ~/.editrc and add:

bind "\e[3~" ed-delete-next-char

or just use default shortcuts here: http://www.bigsmoke.us/readline/shortcuts
Those are valid for both libedit and readline.

My guess is that irc, ipython etc. are compiled against readline and your 
distros provide a global /etc/inputrc where the bindings are defined.

@cataphract: Thanks, your tip - for DELETE key - run fine!
$ cat ~/.editrc
bind "\e[3~" ed-delete-next-char
