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  lt modulename gt    To disable an installed module   php5dismod  lt modulename gt    Ubuntu 16 04  php7  and higher   To enable an installed module   phpenmod  lt modulename gt    To disable an installed module   phpdismod  lt modulename gt    Reload Apache  Remember to reload Apache2 after enabling disabling   service apache2 reload

To check if this extensions are enabled or not  you can create a php file i e  info php and write the following code there    lt  php  echo  GD     extension loaded  gd      OK     MISSING     lt br gt    echo  XML     extension loaded  xml      OK     MISSING     lt br gt    echo  zip     extension loaded  zip      OK     MISSING     lt br gt      gt    That s it

Perhaps the easiest way to see which extensions are  compiled and  loaded  not in cli  is to have a server run the following    lt  php  ext   get loaded extensions    asort  ext   foreach   ext as  ref        echo  ref     n       PHP cli does not necessarily have the same extensions loaded
