Debug PHP code using the Xdebug PHP Extension.
This is currently an alpha release, and still in active development.
You may already have Xdebug installed. Check the results of the phpinfo function for xdebug information. If no xdebug section exists, you likely need to install this. *nix users can likely find it within their package manager of choice. Alternative installation or compiling instructions are available here.
xdebug.remote_enable=1 xdebug.remote_host=127.0.0.1 xdebug.remote_connect_back=1 # Not safe for production servers xdebug.remote_port=9000 xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_autostart=true
With these settings, PHP will connect to your editor for every script it executes. The alternative is to switch xdebug.remote_autostart to false, and install an Xdebug helper extension for your browser of choice, such as:
These browser extensions will give you a button within your browser to enable/disable Xdebug. The extensions might have configuration options for an "IDE key" (which is used for an XDEBUG_SESSION cookie). The IDE key for Atom with PHP Debug is "xdebug-atom".
It is also possible to run a php script from the command line with Xdebug enabled. You can find more information on this at the Xdebug documentation for Starting The Debugger. See can find a complete list and explanation of Xdebug settings here.
To begin debugging:
Move the cursor to a line you want to break on and set a breakpoint by pressing
Alt+F9, selecting Toggle Breakpoint from the Command Palette (
ctrl+shift+p)or with the php-debug menu (
Packages -> php-debug->Toggle Breakpoint).
This will highlight the line number green, to indicate the presence of a breakpoint.
ctrl+alt+d, selecting 'Toggle Debugging' from the Command Palette or php-debug menu.
If everything worked correctly, you can now use the various buttons/commands to step through the script.
