xmanager for linux

The title may seem stupid. But believe me that is what I have searched for. I wanted to run the applications of a far_away_computer on a local_computer as of they are applications of local_computer
The steps

1. In the sshd_config if far_away_computer check for
   
   

   X11Forwarding yes

2. On the local_computer edit ssh_config to have
   
   

   ForwardX11 yes

   or use the -X flag every time u connect to far_away_computer
3. Once you are connected to far_away_computer from local_computer, start xterm on the far_away_computer.

Both ssh_config and sshd_config will be present in either /etc or /etc/ssh

disable zend layout on home page

$this->_helper->layout()->disableLayout();

where $this represents the controller

Zend Router application.ini

if you want http://domain.com/user to be mapped to http://domain.com/index/index/username/kranthi
use this in your application.ini file

resources.router.routes.route_id.route = "/user/:username/*"
resources.router.routes.route_id.defaults.controller = "index"
resources.router.routes.route_id.defaults.action = "index"
resources.router.routes.route_id.defaults.username = "kranthi"

this code executes before transferring the control to the controller

in zend docs it is mentioned

$router = $ctrl->getRouter();

here $ctrl is an instance of Zend_Controller_Front and should be declared before running your bootstrap file in your index.php (single point of entry) file

$ctrl  = Zend_Controller_Front::getInstance();
$router = $ctrl->getRouter();
.
.
.
$application->bootstrap()
            ->run();

Datatype mismatch

Dont use the typecast blindly. Make it a practice to log datatype mismatches

Syntax highlighter for this blog

Typecasting to int or float

easy solution is

$val = $val + 0;

And PHP will take care of the rest.
If you want to ensure that the variable is integer is_numeric is the way to go. is_int and is_float will be of little help here.
Also note that will always evaluate to true

if ((int)$value == $value)

that is because of the internal typecasting of the equality operator
