I am trying to debug some PHP code and wanted to download the XDebug debugger for PHP. All I see there is Windows binaries for downloading. Is it at all possible to use it on Ubuntu?
Execute the following commands in your terminal.
Download Xdebug - you will need to follow alternate instructions if you don't have PHP5 working on your machine already.
sudo apt-get install php5-xdebug
The package should modify your INI file for you, but just in case you need to edit it yourself open it up and make the following modification - on Ubuntu its typically at /etc/php5/apache2/php.ini - add the following line.
That path might be a little different on your system - just make sure its a fully qualified path to the xdebug.so file on your machine. Also remember to comment out any references to the Zend Debugger - you can't run both at the same time.
Now restart Apache.
sudo /etc/init.d/apache2 restart
You may also need want enable html_errors. Search for html_errors in /etc/php5/apache2/php.ini and make sure it is set to On. A restart of Apache is also required.
html_errors = On
Double-check with phpinfo() to make sure that everything is installed properly - you may also want to set configurations for Xdebug in your php.ini file.
