How do I see the extensions loaded by PHP?

Solution 1:

Running

php -m
will give you all the modules, and
php -i
will give you a lot more detailed information on what the current configuration.

Solution 2:

Run command. You will get installed extentions:

php -r "print_r(get_loaded_extensions());"

Or run this command to get all module install and uninstall with version

dpkg -l | grep php5

Solution 3:

You want to run:

 php -m 

on the command line,

or if you have access to the server configuration file open

/etc/php5/apache2/php.ini

and look at all the the extensions,

you can even enable or disable them by switching between On and Off like this

<Extension_name> = <[On | Off]>
