I have a LAMP box running Ubuntu, Apache 2 and PHP5 with Slicehost. I'm a bit new to all this sysadmin stuff (I'm primarily a web developer).

I need to use the IMAP functions in PHP, but they don't seem to be enabled according to phpinfo(). How do I enable them?

All of the information I can find on the net says I need to recompile PHP to add it, but I don't have a clue how to do that.

Any advice would be most appreciated. Thanks.

Well, that depends on the distribution your LAMP server is running on. For example with Debian you can install the PHP5 IMAP module straight from the package manager with command apt-get install php5-imap.

  • I tried this, but the IMAP functions still don't show up in the php.ini (even after rebooting Apache and the whole server). I played with a LAMP box a few years back with the original PHP and Apache and remember having to open php.ini and uncomment a line to activate a module - I can't see any sign of that now though.

  • What extensions are listed in php.ini or other ini files? Is there somewhere a line like extension=imap.so? If not, just add it. Commented Aug 23, 2010 at 9:56
  • I re-performed your original suggestion, rebooted apache and it's now working - I must have cocked something up the first time. Thanks! Commented Aug 23, 2010 at 10:28

    It's not enough to install it. You have to enable it as @JohnSimmonds mentionned.

Carry out the following:

apt-get install php5-imap

However it's not enabled by default so enable it with:

php5enmod imap

Then bounce apache:

service apache2 restart

Check the PHP version:

$ php -v

Suppose shows 7.0.32. So your FastCGI Process Manager(fpm) tool version is 7.0

Now install IMAP ENABLE and ENJOY!! Follow below commands.

# sudo apt-get install php7.0-imap
# phpenmod imap

Restart & Enable service:

# sudo systemctl restart php7.0-fpm
# sudo systemctl enable php7.0-fpm

Check now.. IMAP is enabled!
