[SOLVED] php invoke ... already enabled for PHP 7.0

[joneall]

After installing apache2 and php7.0,. php is simply not working:

$ ps -edf | grep -i php
root 1274 1 0 08:19 ? 00:00:00 php-fpm: master process (/etc/php/7.0/fpm/php-fpm.conf)
www-data 1282 1274 0 08:19 ? 00:00:00 php-fpm: pool www
www-data 1283 1274 0 08:19 ? 00:00:00 php-fpm: pool www
jon 3240 1975 0 08:25 pts/0 00:00:00 grep --color=auto -i php

I don't think this is adequate. And opening phpinfo.php with a browser just shows up the contents of the file.

In /var/syslog, I find a bunch of lines like this:

Feb 26 08:01:01 jon-neon php7.0-cli: php_invoke ctype: already enabled for PHP 7.0 cli SAPI
Feb 26 08:01:01 jon-neon php7.0-cli: php_invoke gettext: already enabled for PHP 7.0 cli SAPI
Feb 26 08:01:01 jon-neon php7.0-cli: php_invoke sysvsem: already enabled for PHP 7.0 cli SAPI
Feb 26 08:01:01 jon-neon php7.0-cli: php_invoke exif: already enabled for PHP 7.0 cli SAPI

What in the world does php have to do with exif?

In auth.log, I find

Feb 26 08:20:02 jon-neon systemd: pam_unix(systemd-user:session): session opened for user jon by (uid=0)

Also, dist-upgrade has messed up my grub, which is now some sort of neon stuff and ignores all but /dev/sda. I suppose that is another topic.

A bunch of questions:
- How did you install php and apache?
- What happens when you go to http://localhost?
- What does the contents of the apache log look like?
- Whats the output of php --version?

[joneall]

1 - sudo apt-get install apache2 php7.0

2 - I see the index file I put there, with links to some local stuff and with phpinfo.php right thre, as I have always done.

Don't know anything about zend. Thanks for helping!

Oh, yes, phpinfo.php contains

<?php

// Show all information, defaults to INFO_ALL
phpinfo();

// Show just the module information.
// phpinfo(8) yields identical results.
phpinfo(INFO_MODULES);

?>

I have had no more answers on this subject., but unfortunately the problem persists unchanged. I have further checked and going via a browser thru localhost to phpinfo.php adds nothing to /var/log/php7.0-fmp.log. It's as if php is not even being called.

No ideas? I don't much want to go back to standard Kubuntu. Kind of got used to Neon.

Found fix, but why?

I found a guy with the same problem on Ubuntu 16.04 here and then did the following:

$ php -r 'echo "\n\nYour PHP installation is working fine.\n\n\n";'

Your PHP installation is working fine.

$ sudo apt-get install libapache2-mod-php
$ sudo service apache2 restart
$ sudo a2enmod php7.0
$ systemctl status apache2.service

Then, AFTER reloading phpinfo.php, it works. So i think it was the install of libapache2-mod-php, whatever that is, which did it.

QUESTION: Why did that not get installed along with apache2?

[GreyGeek]

Because not everyone uses PHP.
