php - Fatal error: Call to undefined function expect_popen() -

since upgrade php 5.5.9 5.6 on ubuntu 14.04 lts server have been getting problems expect library php. keeps displaying fatal error in description. believe package need libexpect-php5. installation checks confirm installed:

root@k1:/etc/php5/conf.d$ dpkg --get-selections | grep -v deinstall | grep expect empty-expect                            install expect                                  install expect-dev                              install expect-lite                             install libexpect-ocaml                         install libexpect-ocaml-dev                     install libexpect-perl                          install **libexpect-php5**                      install // installed right? libexpect-simple-perl                   install libghc-hspec-expectations-dev           install libghc-hspec-expectations-doc           install libghc-hspec-expectations-prof          install libnet-scp-expect-perl                  install libtest-expect-perl                     install netexpect                               install python-pexpect                          install python-pexpect-doc                      install python3-pexpect                         install 

and

root@k1:/etc/php5/conf.d$ expect -v expect version 5.45 

and expect.so files:

root@k1:/usr/lib$ ls | grep expect libexpect.so libexpect.so.5 libexpect.so.5.45 

and /etc/php5/apache2/php.ini file:

extension=expect.so 

i had install libexpect-ph5 downloading , installing .deb file manually, because erring uninstallable dependency api... when , apt-get update && apt-get upgrade keeps telling me this:

the following packages have been kept back:   libexpect-php5 

just installing package something, system still keep package back. leaves me php version doesn't know expect_popen() function.

how solve this?

i found out apache2 loading wrong php.ini file. since upgrade php 5.6 path has changed (of course).

old location:

/etc/php/apache2/php.ini 

new location:

/etc/php/5.6/apache2/php.ini 

along had specify exact path expect.so extension in php.ini.
