 +====== Remote Debug PHPAGI Scripts ======
  
 +You can debug PHPAGI scripts remotely using the debugger from Zend Studio for Eclipse.
 +
 +===== Requirements =====
 +
 +You'll need some stuff!
 +
 +  - Zend Debugger from www.zend.com.
 +  - Apache running on the Asterisk server.
 +
 +===== Installing the Debugger =====
 +
 +  * Download the debugger from Zends website.
 +
 +  wget http://​www.hurdmanivr.com/​download/​ZendDebugger-5.2.12-linux-glibc23-i386.tar.gz
 +
 +  * Extract the file.
 +
 +  tar -xzf ZendDebugger-5.2.12-linux-glibc23-i386.tar.gz
 +
 +  * Find out which version of PHP you are running.
 +
 +  PHP -v.
 +
 +  * Switch to the directory, which you just extracted, that matches the version of PHP you are running.
 +
 +  cd 5_2_x_comp
 +
 +  * Find out where your PHP modules are.
 +
 +  grep extension_dir /​etc/​php.ini
 +
 +  * Copy the appropriate ZendDebugger.so into your PHP modules path.
 +
 +  cp ZendDebugger.so /​usr/​lib/​php/​modules
 +
 +  * Add the following lines to the php.ini file.  The allow_hosts line should include a remote IP as well.  Can be a comma separated list.
 +
 +  ; Zend Debugger
 +  zend_extension = "/​usr/​lib/​php/​modules/​ZendDebugger.so"​
 +  zend_debugger.allow_hosts = "​127.0.0.1"​
 +  zend_debugger.expose_remotely = always
 +
 +  * Copy the dummy.php file into the root of your web server.
 +
 +  cp dummy.php /​var/​www/​html/​
 +
 +  * Restart apache. ​ The command below works for Redhat, Fedora Code, CentOS and other Redhat based distros.
 +
 +  service httpd restart
 +
 +
 +===== Create a Debug Script =====
 +
 +You'll need to set some Zend debugging values and then start Asterisk in console mode.  If Asterisk is already running, stop it first.
 +
 +Create a debug_asterisk.sh file containing the following lines.
 +
 +<​code>​
 +#!/bin/sh
 +export QUERY_STRING="​start_debug=1&​debug_host=localhost&​no_remote=1&​debug_port=40814&​debug_stop=1&​debug_session_id=1003"​
 +asterisk -vvvvc
 +</​code>​
 +
 +Note hat this uses localhost and the 40814 port.  You will use localhost when using a tunnel. ​ Also, the port will change, possibly with each connection. ​ Look at the URL that Zend uses to get the correct port number.
 +
 +===== Setup the Tunnel =====
 +
 +On the client machine, which is running Zend Studio...
 +
 +  * Select the drop-down next to the tunnel icon and select //​Servers//​.
 +
 +  * Add a new tunnel to the Asterisk server machine.
 +
 +===== Start the Zend Debugger =====
 +
 +  * Select //Run//, //Debug URL//.
 +
 +  * Enter the URL of your asterisk server. ​ I use the IP of the machine and run apache on a non-standard port.
 +
 +  http://​67.50.48.18:​50180
 +
 +  * Click the //Debug// button.
 +
 +===== Launch Asterisk =====
 +
 +  * Make sure that your debug_asterisk.sh script starts on the same port that Zend used in the previous step (hint: look at the query string in Zend).
 +
 +  * Start asterisk with your debug_asterisk.sh script.
 +
 +That's it.  It will probably be a little slow, but Zend should open the debug tools and allow you to step through your PHPAGI code line by line, set break points, etc.
