I know how to fadeout an item added to the dom (A success/error message in this case), but the way I'm doing it now is by writing the code to fadeout the specific item I need when it is loaded with the DOM, but also writing seperate fadeOut code when the item is added via AJAX.</p>
<p>Is there a more elegant way to handle this?
I looked into using the .live() handler but that requires an event be passed in as one of its parameters (not good because I just want the item to fade out after a set amount of time, no matter what).</p>
<p>tldr; I'm trying to write a piece of code that will fadeOut an item whether it loads with the DOM or is added to it (via AJAX for example). </p>

1,177,666 | 1,177,667 | why is PHP not throwing a parse error? | <p>There are lots of "Why does PHP throw an error here?" questions. Well, this is a little different. I found the following code while reworking some code written by a coworker:</p>

echo $value;
// ...
}

<p>My first thought: "Umm...how embarrassing; he must have accidentally pasted that in there..." followed by: "Wait...there's no way this code actually runs...that should be a syntax error". And yet:</p>
<pre><code> $ php -l test.php
No syntax errors detected
</code></pre>
<p>And indeed, (like so much PHP code that seemingly shouldn't run) it runs in production without trouble. So I did a little testing:</p>
<pre><code>foreach($arr as $key => $value) {http://google.com/ <-- original, no error
foreach($arr as $key => $value) {http: <-- also no syntax error
foreach($arr as $key => $value) {http <-- bingo! "Unexpected T_ECHO..."

<p>I need to have a List or something similar where each person can tell if they are older or younger than the average age. (Ideally I want to say top 10% and bottom 10%) but I will settle for over under median.</p>
<p>Is there a way to do this?</p>
<pre><code>List<Person> people = new List<Person>();
//Fill People
foreach(var person in people)
{
if (person.TopTenPercent)

<p>And here is where I'm stuck. This is the first time I've used this type of loop before and I don't know what's going on. I have seen tutorials just pass over this loop with a "you should know what happens here" attituded. So if you could explain this loop that would be great also. </p>

<pre><code>if ($body.html().indexOf('&nbsp;') > -1) {
$body.find(':*:not(:has(*))').each(function(){
// These nodes don't have any children so contain text or nothing
$(this).html($(this).html().replace(/&nbsp\;/,''));

4,311,077 | 4,311,078 | toggle information on and off, pulling from separate file | <p>I'm writing code that will, when a button is clicked, display some simple text (a changes log), and then when clicked again will hide it.</p>
<p>The trick here is that I'd like to keep that change log in a separate file, and call it for display. I've got code like follows:</p>
<pre><code> echo "<input type=\"button\" id=\"recentchanges\" value=\"Show/Hide Recent Changes\" /></br><span id=\"changestext\"></span>";
</code></pre>
<p>And:</p>
<pre><code>$('#recentchanges').click(function() {
$('#changestext').append(test/recentchanges.txt);
});
</code></pre>
<p>So my questions are. 1. How can I hide/show by clicks? It doesn't look like .toggle() is what I want.. but perhaps it is.. And 2. How can I call data from a separate file? (and as part of that question, should it be a txt file or an html file? Should I have the text formatted with html, or just raw text?)</p>

<p>I have three menus where you select and option and for each menu you select it displays a row of data.

I created another select that you select a default provider and onchange the other menus in the rows change. The problem I have is that they all have the same id because when you pick an option a function gets called. I tried to loop through all select and from those selects with id=x change selected option but only works for 1st select found with that id</p>
<pre><code>echo" function pickprovider($name, $idname){ \n";

<p>I have seen some terrible code. But why blame the language? I mean it's not like PHP is some kind of ol-procedural style pile of mess people describe it to be. By looking at PHP frameworks, I don't really see any mess or bad code there.</p>
