The Installation Procedure is always the same  but the package-manager and package-name varies  depending which distribution  version and or repository one uses  In general  the steps are      a  at first  user privilege escalation is required  either obtained with the commands su or sudo       b  then one can install the absent PHP module with a package manager       c  after that  restarting the apache2 HTTP daemon is required to load the module       d  at last  one can run php -m   grep imap to see if the PHP module is now available    On Ubuntu the APT package php5-imap  or php-imap  can bei installed with apt-get   apt-get install php5-imap service apache2 restart   On Debian  the APT package php5-imap can be installed aptitude  or apt-get    aptitude install php5-imap apache2ctl graceful   On CentOS and Fedora the RPM package php-imap can be installed with yum  hint  the name of the package might be something alike php56w-imap or php71w-imap  when using Webtatic repo    yum install php-imap service httpd restart   On systemd systems  while using systemd units  the command to restart unit httpd service is   systemctl restart httpd service   The solution stated above has the problem  that when the module was already referenced in    etc php5 apache2 php ini   It might throw a   PHP Warning   Module  imap  already loaded in Unknown on line 0   That happens  because it is referenced in the default php ini file  at least on Ubuntu 12 04  and a PHP module must at most be referenced once  Using INI snippets to load modules is suggested  while the the directory  etc php5 conf d   that path may also vary  is being scanned for INI files    etc php5 conf d imap ini   Ubuntu also features proprietary commands to manage PHP modules  to be executed before restarting the web-server   php5enmod imap php5dismod imap   Once the IMAP module is loaded into the server  the PHP IMAP Functions should then become available  best practice may be  to check if a module is even loaded  before attempting to utilize it

Simple enough  the IMAP extension is not activated in your PHP installation  It is not enabled by default  If your local installation is running XAMPP on Windows  you have to enable it as described in the XAMPP FAQ      Where is the IMAP support for PHP       As default  the IMAP support for PHP is deactivated in XAMPP  because   there were some mysterious initialization errors with some home   versions like Windows 98  Who works with NT systems  can open the file     xampp php php ini  to active the php exstension by removing the   beginning semicolon at the line   extension php imap dll   Should be    extension php imap dll      Now restart Apache and IMAP should work  You can use the same steps   for every extension  which is not enabled in the default   configuration
