Komodo-ext-docs - Debugging PHP

Download and install Komodo IDE

Create a project

Open up Komodo and create a project in your installed MAMP located on a MAC '/applications/joomla-3.4.3-1/apps/joomla' this will display all files in the left side panel of the IDE. This will allow you to directly edit and debug your code.

Configure IDE for debugging

Modifying the php.ini file

In order to use the debugger you need to modify the php.ini file of the Apache server you are using.

Follow these instructions:

On a MAC using MAMP

Goto /applications/joomla-3.4.3-1/php/etc/php.ini
open up this file with your favourite text editor
do a search for xdebug you should find something like this:


;[XDebug]
;; Only Zend OR (!) XDebug
;zend_extension="/Applications/mampstack-5.5.27-0/php/lib/php/extensions/xdebug.so"
;xdebug.remote_enable=true
;xdebug.remote_host=127.0.0.1
;xdebug.remote_port=9000
;xdebug.remote_handler=dbgp
;xdebug.profiler_enable=1
;xdebug.profiler_output_dir=/tmp

Delete the semicolon ; in front of the text under ';; Only Zend OR (!) XDebug' so it reads like this:


;[XDebug]
;; Only Zend OR (!) XDebug
zend_extension=&quot;/Applications/mampstack-5.5.27-0/php/lib/php/extensions/xdebug.so&quot;
xdebug.remote_enable=true
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.profiler_enable=1
xdebug.profiler_output_dir=/tmp

Then do a search for implicit_flush you will find

implicit_flush = Off

Change the Off to On

implicit_flush = On

Save your changes Restart your apache server
