Can not use command line interpreter

Question

I have tried to execute simple php code in the php interpreter. When I executed the command php -a I getting the message

Interactive mode ena

Answer 1

Because module readline not installed. http://php.net/manual/en/features.commandline.interactive.php

This is how I install the module by recompiling php source codes:

Find previous Configure command:

$ php -i | grep configure
Configure Command =>  './configure'  '--prefix=/usr/local/php7' ...

Then recompile:

./configure --prefix=/usr/local/php7 \
--with-readline \

...

$ make clean 
$ make
$ make test 
$ sudo make install

Check if readline module installed:

$ php m | grep readline
readline

Then start php Interactive shell:

$ php -a
Interactive shell
