PDT(Php Development Tool) debugger setup

To get source-level debugging for php in PDT,
have to install Zend Debugger or XDebug Debugger.

//=== Zend Debugger Installation [ref: thierryb.net]:
UPDATE URL: http://downloads.zend.com/pdt
*** use "Help -> Install New Software"
instead of "Help -> Software Updates -> Find and Install"

* Zend Debugger Client:
 php.ini modification to make Zend Debugger client work with Mysql(only for PDT installed on MS Windows?)

* Zend Debugger Server:
download "Studio Web Debugger" from http://www.zend.com/products/studio/downloads


//=== Examples for PDT debug setting using Zend Debugger:

//=== phpinfo
PHP Version     5.3.2-1ubuntu4.7

//=== extension_dir  /usr/lib/php5/20090626+lfs   
put the extracted ZendDebugger.so under the extension_dir

//=== php.ini  edit (better back it up before editting)
sudo gedit /etc/php5/apache2/php.ini

set(or comment out) the following attributes:

* zend_debugger.allow_hosts
zend_debugger.allow_hosts=127.0.0.1/32, 192.168.0.0/16


; this is to see output while debugging
implicit_flush = On

* The output buffering functionality must be switched off to see debug output, too.
output_buffering = 0

[ Note: Remember that output buffering is necessary to allow you to send header (e.g. cookies) even after you sent body content.
Rrestore output_buffering to its original value when we get an error message like "Warning: Cannot modify header information - headers already sent",]


* Disable eAccelerator if it is installed and enabled:
eaccelerator.enable="0" (string or digit?)


* Disable the Xdebug extension by commenting out
;zend_extension=/usr/lib/php4/20020429/xdebug.so

* Disable DBG Debugger, too :
;extension=dbg.so
;extension=php_dbg.dll


* For linux, copy the following lines into the end of php.ini
[Zend]
zend_extension=/usr/lib/php5/20090626+lfs/ZendDebugger.so
zend_debugger.allow_hosts=<comma separated ip_addresses>
zend_debugger.expose_remotely=always

//=== restart web server
sudo /etc/init.d/apache2 restart
