Big Numbers

[eluser]jshvrsn[/eluser]
I seem to have troubles with CI when sending certain strings as function parameters. It looks like any string that looks like an exponential number and is greater than a certain size kills CI. It doesn't matter what's in the function, in fact, the function can be empty.

For Example:

The string "1E47" can be sent fine, but "1E48" cannot.

http://myip/index.php/mycontroller/myfunction/1E47 == OK
http://myip/index.php/mycontroller/myfunction/1E48 == FAIL

function myfunction( $x )
{
}

Am I doing something wrong?

Thanks.

Works fine here using PHP 5.2.5... which PHP version are you using?
HAve you tried it outside CI interface, in plain PHP?

I'm using PHP 5.2.5 running as FCGI under Lighttpd 1.4.15 on a ARM processor running Linux. I also happen to be using CI 1.5.4.

What I found is that in the _set_route_mapping() function in Router.php, there is this little chunk of code:

Code:

// Explode the URI Segments. The individual segments will
// be stored in the $this->segments array.    
foreach(explode("/", preg_replace("|/*(.+?)/*$|", "\\1", $this->uri_string)) as $val)
{
   // Filter segments for security
   $val = trim($this->_filter_uri($val));

   if ($val != '')
      $this->segments[] = (string) $val;
}

and if I change

Code:

if ($val != '')

to

Code:

if ($val !== '')

then it works fine.

I don't see this problem on my desktop machine running Apache. Could it somehow be an issue in Lighttpd?

I tried CI 1.6.1 today and see the same problem. However, the _set_route_mapping() function has been changed, so I haven't found where to apply the fix yet.

Is there any error/warning/notice message? What does var_dump($var) and var_dump('') return?

[eluser]jshvrsn[/eluser]
No warnings, it just hangs.

var_dump( $val ) = string(4) "1E48"
var_dump( '' ) = string(0) ""

[eluser]jshvrsn[/eluser]
I did a very simple test to narrow this down.

I made a file with this content:

Code:

<?php echo( "1E48" != '' ); ?>

Then I ran it from the command line. PHP hung. So I guess that proves the problem is somehow with my cross-compiled PHP.

Sorry for the distraction, I'll take my investigation over to the PHP site.

Thanks for trying to help me out!
