What does each Xdebug parameter mean?
xdebug.show_error_traceType: integer, Default value: 0, Introduced in Xdebug >= 2.4
When this setting is set to 1, Xdebug will show a stack trace whenever an Error is raised - even if this Error is actually caught.
xdebug.remote_connect_backType: boolean, Default value: 0, Introduced in Xdebug >= 2.1
If enabled, the xdebug.remote_host setting is ignored and Xdebug will try to connect to the client that made the HTTP request. It checks the $_SERVER['HTTP_X_FORWARDED_FOR'] and $_SERVER['REMOTE_ADDR'] variables to find out which IP address to use.
If xdebug.remote_addr_header is configured, then the $SERVER variable with the configured name will be checked before the $_SERVER['HTTP_X_FORWARDED_FOR'] and $_SERVER['REMOTE_ADDR'] variables.
This setting does not apply for debugging through the CLI, as the $SERVER header variables are not available there.
Please note that there is no filter available, and anybody who can connect to the webserver will then be able to start a debugging session, even if their address does not match xdebug.remote_host.
xdebug.remote_enableType: boolean, Default value: 0
This switch controls whether Xdebug should try to contact a debug client which is listening on the host and port as set with the settingsxdebug.remote_host and xdebug.remote_port. If a connection can not be established the script will just continue as if this setting was 0.
The above was a copy and paste for Xdebug's documention. Please refer to Xdebug's documentation for more information.
