<p>Without any programming experience whatsoever, I started studying PHP beginning in the second quarter of this year with the goal of slowly building my dream website starting later this summer.</p>
<p>Just as I was wrapping my head around PHP and beginning--I felt-- to truly understand the different concepts and how the code works (this is why I prefaced my post with my non-experience--I've really had to bang and cram it all in my head), I come across Object Oriented PHP.</p>
<p>I've taken the approach of of mastering (trying, as much as possible, at least) as many of the concepts and ideas before diving in to try and create my own scripts; much like learning how to dribble, throw a baseball or football well, before playing a single game. (of course I've played around with and done some code -drills).</p>
<p>My question to the experts is this: Should or must I learn and delve deep
into Object-Oriented-PHP, thus delaying my "start-to-code" date? Or will procedural PHP Programming suffice if one would like to build good E-commerce, forum/comment-type (like PHP Help) or basic social networking websites?</p>

But after installing and uninstalling python 2.7 and 3.2 a few times too many (i just found out 3.x doesn't support some of the 3rd party libraries like PIL), i have lost .py file association(when i double click my python scripts, windows asks me to choose a program to open it with instead of making python interpret it). How can i fix the issue?</p>

4,329,998 | 4,329,999 | Python get class name | <p>So i have this problem, i want to get the name of a python class in this way:</p>
<pre><code>class TestClass():
myName = (get class name here automatically)
saveDirectory = os.path.join(saveDir, myName) # so i can save it in unique location
def __init__(self):
pass # do something
</code></pre>
<p>However, it seems that <code>__class__.__name__</code> doesn't actually exist as of yet at the time when <code>myName</code> is created. So i have been forced to put that into the <code>__init__()</code> function, like this:</p>
<pre><code>class TestClass():
def __init__(self):
self.myName = self.__class__.__name__
saveDirectory = os.path.join(saveDir, self.myName) # so i can save it in unique location
pass # do something
</code></pre>
<p>But this has a big problem, because I cannot get the name of the class until I instantiate the class, I instend to create a few gigabytes of data for each instance of the class to be saved in the saveDirectory, so it can be re-used later. So I don't actually want to do go ahead with my current solution.</p>
<p>Is there anyway to get the class name as I have intended? Or am I just dreaming?</p>
<p>EDIT:</p>
<p>Thanks guys for your great suggestions. I am going to spend a little bit of time taking a look at Metaclasses. Otherwise, I will probably create a dictionary globally, and have references to these instantiated classes instead.</p>

<p>I have the logic that plays the sound every minute in the active state using a runnable and handler. The app works fine if you press the start or stop buttons. </p>
<p>If you run the app and hit stop it kills the app. If you run the app hit home the sounds continue to play and when you relaunch the timer will be up to date. This is expected.</p>
<p>The problem i am having is that if you hit home and then launch another app, there is a high chance my app gets killed and the sounds will no longer play (and consequently GUI will is reset when you relaunch)</p>
<p>My question is, <strong>What approach should i use so that my app will continue to play the sounds until i tell it to stop, even if its not in the foreground?</strong> The sounds can be thought of as a reminder to the user.</p>
