[PHP] database credentials with ini_set() question?

[dsiembab01]

I know that phpinfo() will show the pass and username as plain text, but 
other than that what are the security reasons for not using ini_set() 
for database credentials?

NOw if they would cover the Zend Library I might pay a dollar.

Then do not reply.  It was an offer to the community at large, not
just you and the other top-poster.  ;-P

you could read this
http://xdebug.org/docs/execution_trace
and then parse trace files to get the memory usage
create a global to store user functions, I think user function do not 
populate get_defined_functions(); until the function is called;

$t = get_defined_functions();
$userFunctions = $t['user'];
$file = xdebug_get_tracefile_name();
parse the file and then create a function to call the said variable.
I think you can figure it out.

Currently it's mostly procedural with some components that are OO.  I 
suspect most of the memory sinks are large arrays (we have a lot of 
them), but I am not certain of that.  Hence my interest in more accurate 
investigation tools.

That's not really what I'm after.  Let me try an example:

  if (empty($foos[$id]) {
$foos[$id] = load_foo($id);
  }
  return $foos[$id];
}

When load_foo() is slow (e.g., lots of DB traffic or remote-server 
calls or whatever), such caching can have a significant performance 
boost. Sometime after foo() has been called 15 times from 30 places 
in code, when I get to the end of the request (or just every time I 
call foo() would be fine) I want to be able to do something like:


$cost = get_memory_used_by($foos);

So that I can determine how much memory that caching is costing me 
over the lifetime of the page, and determine if it's a worthwhile 
trade-off.

something like this?
you can put it wherever you like and returns an array for further 
processing. You could optionally add a second argument to set the 
index to a name and check if the name exists to add 1 to the end of 
the name so your indexes stay maintained.

a good tool for mapping mysql databases is mysql-workbench.
the real question is how much normalization is normal?
