What to do if the php extension is not loaded

Problem Restore:

I'm trying to install the ssh2 extension for php and am having a little difficulty, the files are there, it just doesn't load to PHP.

(Recommended tutorial: java video tutorial)

First I installed ssh2:

 aptitude install libssh2-1-dev libssh2-php

(For what it's worth, I'm running on Nginx Ubuntu 12.04)

I can see loading ssh2 using the modules command:

php -m |grep ssh2
ssh2

But when I run my code I get an undefined function error.

In my phpinfo() script I can see that my php installation scans this directory for other ini files: /etc/php5/fpm/conf.d lists the contents of this directory and I Can see my ssh2.ini is there:

ls /etc/php5/fpm/conf.d
mysqli.ini  mysql.ini  pdo.ini  pdo_mysql.ini  ssh2.ini

Again according to phpinfo, the other four ini files are loaded, SSH2 is not.

I also tried putting "extension=ssh2.so" directly in my php.ini file /etc/php5/fpm/php.ini and restarting the nginx server.

Solution:

1. Set "display_startup_errors = On" in php.ini

2. Set "error_log ='/var/log" in php.ini /php_error.log'"

3. Create an error log, touch /var/log/php-error.log

Restart the php5-fpm daemon and look for the ssh2 module in the error log any errors.
