Problem with readline.so

apt-get install php5-readline
php5 -i |grep Readline
Readline Support => enabled
Readline library => EditLine wrapper
1. Which library does this EditLine wrapper refer to?
2. How to open readline.so?

find / -name 'readline.so*'
/usr/lib/php5/20131226/readline.so
/usr/lib/x86_64-linux-gnu/libreadline.so
/usr/lib/x86_64-linux -gnu/ruby/2.1.0/readline.so
/usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so.18
/usr/lib/x86_64-linux-gnu/libguilereadline-v-18 .so
/usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so.18.0.0
/usr/lib/python2.7/lib-dynload/readline.x86_64-linux-gnu.so
/ lib/x86_64-linux-gnu/libreadline.so.6.3
/lib/x86_64-linux-gnu/libreadline.so.6
