Problems installing xdebug.so extension on local AMP environment - php

Question

Edit: I've now removed the version of xdebug.so I installed manually, and installed XDebug via Homebrew. When I type "php -i" at the command line, xdebug appears to be installed; but when I run phpinfo(), there's still no sign of XDebug.
I've just got a new Mac so, like every time I buy a new Mac, I have rebuilt my local web development environment (this time, following an amazing tutorial: https://echo.co/blog/os-x-1010-yosemite-local-development-environment-apache-php-and-mysql-homebrew)
Everything has gone smoothly until I got to installing the XDebug extension. I use Komodo as a development environment so, as I've always done in the past, I followed the instructions here: http://docs.activestate.com/komodo/7.1/debugphp.html#debugphp_top
I followed the instructions to the letter, but I can't get xdebug.so to appear in my phpinfo.php() page. Here's what I did:
Created a phpinfo.php file so that I can find the correct php.ini file
Checked that phpinfo.php file and found that the "Loaded Configuration File" is "/usr/local/etc/php/5.6/php.ini"
Edited that php.ini, adding the following lines to the bottom of the file:
_
zend_extension=/usr/local/Cellar/php56/5.6.14/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=localhost
xdebug.remote_port=9000
xdebug.idekey=<idekey>
; You may also want this - to always start a remote debugging connection.
;xdebug.remote_autostart=1
Ran "brew services restart httpd22" (and, just to be sure, "sudo apachectl restart")
When I go reload phpinfo.php, it contains to reference to xdebug.so.
I can confirm that xdebug.so is present at /usr/local/Cellar/php56/5.6.14/lib/php/extensions/no-debug-non-zts-20131226 and that /usr/local/Cellar/php56/5.6.14/lib/php/extensions/no-debug-non-zts-20131226 is set as the "extension_dir" in php.ini.
What am I missing?!

Ultimately this proved be to be caused my me doing things in the wrong order. I'd used Homebrew to install Apache and PHP, but I'd installed Apache 2nd: this meant that it wasn't set up to work with the version of PHP I then installed.
I reinstalled PHP using the command brew reinstall php54 --homebrew-apxs, and that ensured that Apache and PHP were talking to each other.
Then, to install xdebug, I ran brew install homebrew/php/php56-xdebug. After restarting Apache, XDebug showed up in phpinfo() straight away!
Then I had to get XDebug talking to Komodo. To do this I added in the config lines from my original post to the specific xdebug config file that had been created during the Homebrew install (mine was located at /usr/local/etc/php/5.6/conf.d/ext-xdebug.ini), and then made sure that Komodo was listening on the correct port (9000 didn't work, so I changed to 9001).
