  • exclude private property from print_r or object?

    - by Hailwood
    Basically I am using Code Igniter, and the Code Igniter base class is huge, when I print_r some of my objects they have the base class embedded inside them. this makes it a pain to get the information I actually wanted (the rest of the properties). So, I am wondering if there is a way I can hide, or remove the base class object? I have tried clone $object; unset($object->ci); print_r($object); but of course the ci property is private. the actual function I am using for dumping is: /** * Outputs the given variables with formatting and location. Huge props * out to Phil Sturgeon for this one (http://philsturgeon.co.uk/blog/2010/09/power-dump-php-applications). * To use, pass in any number of variables as arguments. * Optional pass in "true" as final argument to kill script after dump * * @return void */ function dump() { list($callee) = debug_backtrace(); $arguments = func_get_args(); $total_arguments = count($arguments); if (end($arguments) === true) $total_arguments--; echo '<fieldset style="background: #fefefe !important; border:2px red solid; padding:5px">'; echo '<legend style="background:lightgrey; padding:5px;">' . $callee['file'] . ' @ line: ' . $callee['line'] . '</legend><pre>'; $i = 0; foreach ($arguments as $argument) { //if the last argument is true we don't want to display it. if ($i == ($total_arguments) && $argument === true) break; echo '<br/><strong>Debug #' . (++$i) . ' of ' . $total_arguments . '</strong>: '; if ((is_array($argument) || is_object($argument)) && count($argument)) { print_r($argument); } else { var_dump($argument); } } echo '</pre>' . PHP_EOL; echo '</fieldset>' . PHP_EOL; //if the very last argument is "true" then die if (end($arguments) === true) die('Killing Script'); }

  • Why can't my function access a variable in an enclosing function?

    - by nailer
    I know about the LEGB rule. But a simple test of whether a function has read access to variables defined in an enclosing function doesn't seem to actually work. Ie: #!/usr/bin/env python2.4 '''Simple test of Python scoping rules''' def myfunction(): print 'Hope this works: '+myvariable def enclosing(): myvariable = 'ooh this worked' myfunction() if __name__ == '__main__': enclosing() Returns: NameError: global name 'myvariable' is not defined Am I doing something wrong? Is there more to it than the LEGB resolution order?

  • What does (void**) mean in C?

    - by numerical25
    I would look this up, but honestly I wouldn't know where to start because I don't know what it is called. I've seen variables passed to functions like this: myFunction((void**)&variable); Which confuses the heck out of me cause all of those look familiar to me; I've just never seen them put together like that before. What does it mean? I am a newb so the less jargon, the better, thanks!

  • Python command line - add PYTHONPATH during module run

    - by orokusaki
    I want to run: python somescript.py somecommand But, when I run this I need PYTHONPATH to include a certain directory. I can't just add it to my environment variables because the directory I want to add changes based on what project I'm running. Is there a way to alter PYTHONPATH while running a script? Note: I don't even have a PYTHONPATH variable, so I don't need to worry about appending to it vs overriding it during running of this script.
