Where is the php.ini which needs to be set up?

The simplest way to find out the path of the php.ini is again with the help of the phpinfo function as described in Section 1.5.1.2, “Find the extension directory”

	Tip
	Another possibility to find out where an application searches specific files is by using a tool called Filemon which you can get from Sysinternals.

The resulting output shows the path of the php.ini file within the topmost header. See Figure 1.10, “Get the php.ini path”

Now open php.ini and search for “implicit_flush”, and set it to “On”.

; this is to see output while debugging
implicit_flush = On 

copy the following lines into php.ini (they can go at the end of the file). For linux it is a php_dbg.so instead of php.dbg.dll.

[debugger]
extension=php_dbg.dll
debugger.enabled=on
debugger.profiler_enabled=on
debugger.hosts_allow=localhost
debugger.hosts_deny=ALL
debugger.ports=7869, 10000/16

Disable eAccelerator if it is installed and enabled:

eaccelerator.enable="0"

Disable the Xdebug extension if installed (usually via pear) by commenting out

;zend_extension=/usr/lib/php4/20020429/xdebug.so

Also if you have Zend Extension Manager installed (You should find a [Zend] section) make sure you add this line before any other zend_extension_ts (windows) or zend_extension (linux) lines: For Windows:

zend_extension_ts = "C:\path\to\php_dbg.dll"

For linux:

zend_extension=/var/lib/php4/dbg.so

Restart web server
