LXXXIII. GNU Readline
The readline() functions implement an interface
to the GNU Readline library. These are functions that provide
editable command lines. An example being the way Bash allows you
to use the arrow keys to insert characters or scroll through
command history. Because of the interactive nature of this
library, it will be of little use for writing Web applications,
but may be useful when writing scripts meant to be run from a
shell.
To use the readline functions, you need to install libreadline and
compile PHP with support for readline.
To compile PHP with readline support, you need to configure PHP
--with-readline after you've installed
libreadline. You can find libreadline on the home page of the GNU
Readline project, at http://cnswww.cns.cwru.edu/~chet/readline/rltop.html.
