The & character in URL will break the curl command in *nix shell due to its default behavior for background process. This trick solved my problem

[sourcecode]
url=’http://example.com?param1=value1&param2=value2′
curl –proxy squid-proxy-server-name:port-number $url
[/sourcecode]

Install guest addition:
http://www.youtube.com/watch?v=mBAbcwsKog8

Shared folder:

• click Devices => Shared Folders
• run in shell terminal: mount -t vboxsf shared_folder_name guest_server_path/
• edit /etc/rc.local file and add line: mount.vboxsf -w -o uid=500 shared_folder_name guest_server_path/

create project
[sourcecode]zf.sh create project rsvp[/sourcecode]

Link library
[sourcecode]ln -s /path/to/ZendFramework-1.11.11-minimal/library/Zend .[/sourcecode]

set up access permission for application/ folder by add .htaccess file with line:
[sourcecode]deny from all[/sourcecode]

To set the project as a sub-folder instead of document root (common in shared hosting), one has to set up path redirect. First, we need to change .htaccess file under the project folder to add path rewrite function (Note: need to make sure apache httpd.conf has the “AllowOverride All” set for the folder)

[sourcecode]
RewriteRule (.*) ./public/$1
[/sourcecode]

Second, we can edit configs/application.ini and add a line
[sourcecode]settings.baseUrl = "/rsvp"[/sourcecode]

Third, edit Bootstrap.php and add a function
[sourcecode]
protected function _initBaseUrl()
{
$options = $this->getOptions();
$baseUrl = isset($options[‘settings’][‘baseUrl’])
? $options[‘settings’][‘baseUrl’]
: null; // null tells front controller to use autodiscovery, the default
$this->bootstrap(‘frontcontroller’);
$front = $this->getResource(‘frontcontroller’);
$front->setBaseUrl($baseUrl);
}
[/sourcecode]

create layout
[sourcecode]zf.sh enable layout[/sourcecode]
and then edit application/layouts/layout.phtml to add necessary header/footer inclusion.

set up database by editing application/configs/application.ini file
[sourcecode]
resources.db.adapter = PDO_MYSQL
resources.db.params.host = localhost
resources.db.params.username = my_username
resources.db.params.password = my_password
resources.db.params.dbname = my_db
[/sourcecode]

create controller
[sourcecode]zf.sh create controller controllername[/sourcecode]

create action
[sourcecode]
zf.sh create action add controllername
zf.sh create action edit controllername
zf.sh create action delete controllername
[/sourcecode]

create model
[sourcecode]
zf.sh create db-table controlername db_table_name
[/sourcecode]

and then modify application/models/DbTable/ProjectName.php to add CRUD DB functions.
