Apache Mod Rewite

Apache Mod Rewrite is enabled and Rewrite Engine is on, yet rewrite is not working

Likely reason is that AllowOverride is set to None. Changing back to All will resolve the problem
If the problem persists try

RewriteLog logfile
RewiteLogLevel level; 0 - no log 9 - highest 

No log means mod_rewrite is not executing

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
