3,294,348 | 3,294,349 | Does PHP evaluate variables when a function is defined? | <p>I am creating a multipage form in PHP, using a session. The <code>$stage</code> variable tracks the user's progress in filling out the form, <strong>(UPDATE) and is normally set in $_POST at each stage of the form.</strong></p>
<p>On the second page (stage 2), the form's submit button gets its value like this:</p>
<pre><code>echo '<input type="hidden" name="stage" value="';
echo $stage + 1;
echo '" />;
</code></pre>
<p>That works fine - <code>$stage + 1</code> evaluates to 3 if I'm on page 2. But since I'm doing this more than once, I decided to pull this code out into a function, which I defined at the top of my code, before <code>$stage</code> is mentioned.</p>
<p>In the same spot where I previously used the code above, I call the function. I have verified that the function's code is the same, but now <code>$stage + 1</code> evaluates to 1.</p>
<p><strong>Is PHP evaluating my variable when the function is defined, rather than when it's called? If so, how can I prevent this?</strong></p>
<h3>Update 1</h3>
<p>To test this theory, I set <code>$stage = 2</code> before defining my function, but it still evaluates to 1 when I call the function. What's going on?</p>
<h3>Problem Solved</h3>
<p>Thanks to everyone who suggested variable scope as the culprit - I'm slapping my forehead now. <strong><code>$stage</code> was a global variable, and I didn't call it <code>$GLOBAL_stage</code></strong>, like I usually do, to prevent this sort of problem.</p>
<p>I added <code>global $stage;</code> to the function definition and it works fine. Thanks!</p>

3,350,063 | 3,350,064 | How can I choose if I want to append text or html to a div generically? | <p>I'm writing a javascript library and I need to use jquery's append method to add content to a div. I thought that append() treats <code>"straight strings"</code> as text and <code>$("<div>html objects</div>")</code> as html but apparently if you use <code>append("<p>")</code> then you will get the string parsed into html which means that strings need to be encoded before being appended.</p>
<p>I would like to use something which works like append but which makes distinctions between strings which are to be treated literally and strings which are to be parsed BASED ON THE PARAMETER. Since this is a library I wouldn't like to duplicate all my functions to make text() and html() versions of each.</p>
<p>For example, I want to be able to add the string <code>"<p>xx</p>"</code> without it being parsed to html but when I want to add the same string as html then I would pass <code>$("<p>xx</p>")</code> as a parameter instead.</p>
<p>edit: Basically I'm tired of seeing tutorials use append() to append text, because it does not append text, it appends html. I want to know if there is a method which distinguishes appending strings from appending html objects.</p>

2,999,940 | 2,999,941 | Add values from second array after array values? | <p>There are similar questions however none quite tackes the problem.</p>
<pre><code>Array('1','2','3')
Array('4','5','6')
</code></pre>
<p>Assuming they both have keys 0, 1, 2. Merging the two arrays doesn't allocate the second array values after the first's since it overwrites keys with the same name. Neither using an union array operator (+) works. And using array_push results in this:</p>
<pre><code>Array('1','2','3',Array('4','5','6'))
</code></pre>
<p>How can the values from array2 be added after the ones from array1 maintaining their order?</p>

</blockquote>
<p>I am working in an android application and I want to tweet a message and a picture to twitter. I am able to tweet only tweets to twitter by the code :</p>
<pre><code>String token = prefs.getString(OAuth.OAUTH_TOKEN, "");
String secret = prefs.getString(OAuth.OAUTH_TOKEN_SECRET, "");
AccessToken a = new AccessToken(token, secret);
Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(Constants.CONSUMER_KEY,
Constants.CONSUMER_SECRET);
twitter.setOAuthAccessToken(a);
try {
**twitter.updateStatus("New tweet");**
twitter.//Which property of twitter should I use to tweet an image and //message
} catch (TwitterException e) {
// TODO Auto-generated catch block
Log.e("Errorssssssssssssss", e.toString());
}
</code></pre>
<p>How do I include an image as well?</p>

5,082,664 | 5,082,665 | Equivalent in C# of "Block values" in other languages | <p>In some languages, almost everything can be used as a value. For example, some languages let you treat a block of code as a unit which can return a value.</p>
<p>In Scheme, a block of code wrapped in a <code>let</code> can return a value:</p>
<pre><code>(define val
(let ()
(define a 10)
(define b 20)
(define c (+ a b))
c))
</code></pre>
<p>Perl 5 also supports blocks as values:</p>
<pre><code>my $val = do
{
my $a = 100;
my $b = 200;
my $c = $a + $b;
$c;
};
</code></pre>
<p>The closest approximation to block values I could come up with in C# was to use a lambda that is cast and immediately called:</p>
<pre><code>var val = ((Func<int>)(() =>
{
var a = 10;
var b = 20;
var c = a + b;
return c;
}))();
</code></pre>
<p>That's not too bad and is in fact exactly what is happening semantically with Scheme; the <code>let</code> is transformed to a <code>lambda</code> which is applied. It's at this point that I wouldn't mind macros in C# to clean up the syntactic clutter.</p>
<p>Is there an another way to get "block values" in C#?</p>
