Fatal Error: Call to undefined function imap_open PHP

Question

I have followed the steps below to enable IMAP and still things are not working.


    sudo apt-get install php5-imap
    sudo apt-get install php5-cli
    sudo php5enmod imap 
    service php5-fpm restart
    sudo service nginx restart

I can see the IMAP extension enabled under phpinfo and also can see the extension is loaded using command dpkg -l | grep php5-imap

Server: Linux and using nginx

Make sure you've enabled the module for php5-fpm; just checking the output of `phpinfo()` under the cli won't tell you that it has been successfully enabled for the fpm version. — MatsLindh, Apr 24 '20 at 18:12
@MatsLindh under/etc/php5/mods-enabled i can see the imap.ini present, can you please clarify how can we enabled the module for php5-fpm? — Omair Shahid, Apr 24 '20 at 18:38

`enabled under phpinfo` - how/where? From CLI, or nginx, or both? There are not the same, maybe you have enabled it in one, but not the other? `Fatal Error: Call to undefined ...` - how/where do you see this error, CLI, or nginx? — Don't Panic, May 02 '20 at 02:02

This should be a comment, but I haven't got the reps for comment, so...

Try to check your extension file, i.e. make sure that in /etc/php5/mods-enabled/imap.ini, the keyword extension=/path/to/imap.so is not commented (having ; or # as its beginning of line) and your /path/to/imap.so file exists.
Try to check if you had multiple php-fpm services running. Use systemctl list-unit-files | grep php to check. If you had multiple php-fpm services, make sure you had installed imap extension to the correct php-fpm instance.
