====== Install Xdebug ====== When it comes to PHP programming having the possibility to use a debugger to track problems in your code is a necessity. One of the most popular one in the PHP ecosystem happens to be [[http://xdebug.org|XDebug]]. ===== Getting the package ===== XDebug can be [[http://xdebug.org/download.php|downloaded in a variety of versions]] or even built from [[https://github.com/derickr/xdebug|sources]]. But the Xdebug website also offers an [[http://xdebug.org/wizard.php|installation wizard]] that will help determine what to do to get XDebug working on your system. Follow the simple instructions and you'll soon have XDebug installed and running. <code> mkdir /opt/phpfarm/xdebug $ cd /opt/phpfarm/xdebug $ wget http://xdebug.org/files/xdebug-2.2.3.tgz $ tar -xzf xdebug-2.2.3.tgz $ cd xdebug-2.2.3 </code>
