The lines of code is as follows:

// Mark a start point so we can benchmark the controller
$BM->mark('controller_execution_time_( '.$class.' / '.$method.' )_start');
echo $class;
echo $method;
exit;
$CI = new $class();

if i exit before $CI = new $class(); than my browser does not hangs and prints class and method.
if i place echo and exit after new $class() nothing happnes and browser hangs.

some one psl help me.

What is your definition of 'hanging'?

A webbased application is stateless, so a browser can't 'hang' (at least not in combination with CI, which is server side code).

Start by describing what exactly happens.

hi
thanks for reply.
it hangs in the sense that the following code loops in to indefinite loop.
$CI = new $class(); inside codeigniter.php .
i can argue about the same since i tried to debug by giving echo and exit and the conclusion was that control is never transferred to next statement of $CI = new $class(); codeigniter.php.i know kits silly but i m unable to solve.

If it's really looping, the process will eventually timeout (the default in php.ini is 30 seconds), with a warning.

This is a standard CI, downloaded? Or does it already contain an application? Did you enable CI logging (application/config/config.php, set log_threshold to 4), and did you check the logfile produced? Any error messages in your apache logs?

Hi Wan,
thanks for the reply.
I have downloaded 1.7.2 from the link http://codeigniter.com/download.php.
Logs for CI with log_threshold set to 4 gives following:

DEBUG - 2010-09-18 11:20:03 --> Config Class Initialized

Apache logs does not have any error.

i m just starting to learn example helloworld.

Just debuging withe cho statement helped me to conclude that this line of code ($CI = new $class() in codeigniter.php is never completed.i say it loops.may be other term is appropriate.

The code downloaded doesn't have the database library enabled.

My suggestion is that you have a problem in your database configuration. CI is trying to connect to your database server on a non-responsive hostname and/or port, which means the connect() hangs on the TCP timeout of that connection attempt.

Hi Thanks a lot.
The problem was data CI can not connect to localhost but can connect to 127.0.0.1.
Replacing local host with 127.0.0.1 in config\database.php dod work.
Suggestions :if we have such cases than atleast the app should print a message so that user can know.
BTW it was nice that u could know the reason.Its really suprising for me to know if u can share the way u concluded its DB problem.
