Using VVV for WordPress development is awesome, however sometimes the errors returned are confusing and difficult to debug. Thankfully there’s a PHP extension which makes tracing the errors returned by PHP and WordPress much, much easier and that’s XDebug.
Installing XDebug on your VVV machine is easy:
SSH into your VVV machine with:
Install XDebug with:
sudo apt-get install php5-xdebug
Open your php.ini
sudo vim /etc/php5/fpm/php.ini
Go to the bottom of the file by typing G (capitalized) and enter Insert mode by typing i (lowercase). Paste in the following:
# XDebug Extension zend_extension="/usr/lib/php5/20121212/xdebug.so" xdebug.remote_enable=1 xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000
You can also decide whether you want to limit how much information is shown in a var_dump by adding the following settings below the above code:
# Sane limits xdebug.var_display_max_depth = 5 xdebug.var_display_max_children = 256 xdebug.var_display_max_data = 1024
And if you want no limits on how much information is shown enter the following:
# No limits xdebug.var_display_max_depth = -1 xdebug.var_display_max_children = -1 xdebug.var_display_max_data = -1
Exit and save by typing :wq and hit enter.
Restart PHP5-FPM with:
sudo service php5-fpm restart
And you should be good to go! Let me know if you have any problems!
