Question

PHP execution is throwing a Warning about Imagick...

Output of php -v:

PHP Warning: Version warning: Imagick was compiled against Image Magick 
version #### but version #### is loaded. Imagick will run but may behave
surprisingly in Unknown on line 0

Answer 1

You have certainly upgraded imagick after installing PHP, so you need to reinstall imagick using pecl.

Run the following:

sudo pecl uninstall imagick
sudo pecl install imagick

If you run php -v and see a warning saying that the module imagick was already loaded, check your ini file:

php -i | grep 'Configuration File'

Then open the file and remove duplicate entries of extension="imagick.so". You might need to look into the configuration path to check also other ini files.
