2,162,286 | 2,162,287 | jQuery: I cannot modify an element's CSS color after using append() | <p>I have used jQuery's append() command to create a set of DIVs from an array.</p>

$.each(myArray,function(index,item){
$("#results_panel").append('<div id="result_'+item+'">'+item+'</div>');

1,610,495 | 1,610,496 | Application priority | <p>An application that is running for a long time in foreground will acquire more priority in time?
I explain my problem. I ported a software for communication with a fixed infrastructure in Android. I'm making some tests. Each test makes 5 experiments (the mobile node sends some queries to the infrastructure and evalutes the number of query successful and the mean time) and the result of the test is the mean of the results of these experiments.
During the test the application is always in foreground.
In the experiments the result improve e. g. (10% 15% 30% 40% 55% of query ok).
I implemented the system as activity and not yet as service.
For the test the app aquire the locks SCREEN_DIM_WAKE_LOCK and WIFI_MODE_FULL.

<p>I'm in the road of learning PHP and before I go further with my current coding style, i want to make sure :
Are line breaks and spaces affect the performance of the server ? Usually, I always add them for readibility. for example in the following code :</p>
<pre><code>import('something') ;
$var = 'A' ;
$varb = 'B' ;
switch($var) {
case 'A' :
doSomething() ;
doAnotherThing() ;
break ;
}
if ($var == $varb) { header('Location: somewhere.php') ; }

<ol>
<li>I add space before a semicolon</li>
<li>I add space after and before variable value assignment and comparison</li>
<li>I add space between ) and {</li>
<li>Usually I add a line break after { if the code following it consist of multiple statements.</li>
<li>Inside the curly bracket, I always start with a space before the first statement and ended it with another space after the last statement's semicolon</li>
<li>I always give a 2-space-width tab for every child elements</li>
<li>I always add a space after 'Location:' inside header function.</li>
<li>I always add space before semicolon for each case condition</li>
</ol>
<p>This style is cool for me, I like it, its tidy and it makes me easier to debug, what i wonder is, will this kind of coding style hurt/burden the system ? Will it makes server slower by re-formatting my codes ? So far i got no formatting error.</p>

1,371,235 | 1,371,236 | Using $this->key with overloaded __get() in PHP | <p>I have a dynamically loading class as a variable within another class. I have implemented it as follows:</p>

if ($key == "dr") {
if (!$this->dr) { $this->dr = new DR(); }

<p>When I utilize this function from outside the class it works as expected:</p>

When I use the same technique from inside the class the <code>__get()</code> function does not get called, and I receive NULL:</p>

}
