How to check which PHP extensions have been enabled/disabled in Ubuntu Linux 12.04 LTS?

I'm using Ubuntu Linux 12.04 LTS on my local machine. I've installed LAMP long ago on my machine. Now I want to enable following PHP extensions:

  1. php_zip
  2. php_xml
  3. php_gd2

For it first I want to check whether these PHP extensions are enabled or not. I searched a lot about how to check the installed/enabled PHP extensions but every time I found how to install these extensions on Ubuntu Linux. So can someone please let me know how should I check the enabled/disabled PHP extensions in Ubuntu Linux 12.04 LTS?

To check if this extensions are enabled or not, on the script level, not in CLI, you can create a php file i.e. info.php and write the following code there:

<?php 
echo "GD: ", extension_loaded('gd') ? 'OK' : 'MISSING', '<br>';
echo "XML: ", extension_loaded('xml') ? 'OK' : 'MISSING', '<br>';
echo "zip: ", extension_loaded('zip') ? 'OK' : 'MISSING', '<br>';
?>

That's it.

Tested on PHP 8.1:

Check extension INSTALLED (in Operative System):

php -m

Check extension LOADED (in CLI):

# set EXT value with the desired extension name.
EXT=gmp php -r "echo getenv('EXT'),': ', extension_loaded( getenv('EXT') ) ? 'Loaded' : 'Not loaded', PHP_EOL;"

Check extension LOADED (in PHP-FPM):

echo "<?php phpinfo(); ?>" > public/info.php

and then visit you-running-php-fpm-host/info.php; remember to delete the file afterwards!

Another quick way to see if a module is enabled / disabled vs only installed or not is to use phpquery command.

For example, on my Linux Mint machine, if I want to see if xdebug is enabled I would run:

 phpquery -v 8.1 -s apache2 -m xdebug

-v - is to specify for which version you want

-s - to specify the environment (apache2 or cli)

-m - the module you are interested into.

The response for the above example was (in my case):

xdebug (Enabled for apache2 by maintainer script)

Here some more examples.

Checking for installed php modules and packages

In addition to running

php -m

to get the list of installed php modules, you will probably find it helpful to get the list of the currently installed php packages in Ubuntu:

sudo dpkg --get-selections | grep -v deinstall | grep php

This is helpful since Ubuntu makes php modules available via packages.

You can then install the needed modules by selecting from the available Ubuntu php packages, which you can view by running:

sudo apt-cache search php | grep "^php5-"

Or, for Ubuntu 16.04 and higher:

sudo apt-cache search php | grep "^php7"

As you have mentioned, there is plenty of information available on the actual installation of the packages that you might require, so I won't go into detail about that here.

Related: Enabling / disabling installed php modules

It is possible that an installed module has been disabled. In that case, it won't show up when running php -m, but it will show up in the list of installed Ubuntu packages.

Modules can be enabled/disabled via the php5enmod tool (phpenmod on later distros) which is part of the php-common package.

Ubuntu 12.04:

Enabled modules are symlinked in /etc/php5/conf.d

Ubuntu 12.04: (with PHP 5.4+)

To enable an installed module:

php5enmod <modulename>

To disable an installed module:

php5dismod <modulename>

Ubuntu 16.04 (php7) and higher:

To enable an installed module:

phpenmod <modulename>

To disable an installed module:

phpdismod <modulename>

Reload Apache

Remember to reload Apache2 after enabling/disabling:

service apache2 reload

For information on php extensions etc, on site.

  1. Create a new file and name it info.php (or some other name.php)

  2. Write this code in it:

     <?php
       phpinfo ();
     ?>
    
  3. Save the file in the root (home)of the site

  4. Open the file in your browser. For example: example.com/info.php All the php information on your site will be displayed.

Perhaps the easiest way to see which extensions are (compiled and) loaded (not in cli) is to have a server run the following:

<?php
$ext = get_loaded_extensions();
asort($ext);
foreach ($ext as $ref) {
    echo $ref . "\n";
}

PHP cli does not necessarily have the same extensions loaded.

You can view which modules (compiled in) are available via terminal through php -m
