    array_unshift($array, &quot;Choose City&quot;)

or you can do it manually

I think you are looking for [`array_unshift()`](http://php.net/manual/en/function.array-unshift.php) - this adds an element to the beginning of the array, rather than the end, without overwriting any existing elements.

However, the array will now be indexed starting at `0`...

If you know that Index 0 is not used you can simply assign it:

    $array[0] = &quot;Choose City&quot;;

I started learning ASP.NET MVC3. 

So, while reading tutorials  online and in books, I came across this term *&quot;view engine&quot;* quite frequently. I don&#39;t know what it is. 

What does it actually do? 

Why should it matter to me at all?

I have an array that doesn&#39;t use the 0 index. The array starts from 1,2,3. So I would like to add to the array. I tried do `array_push($array, &quot;Choose City&quot;)`, but this ends up at the end of the array, with array index 4 in this case.

How can I set it to be the array index 0?

How can I display a string that contains HTML tags in twig template?

My PHP variable contains this html and text:

    $word = &#39;&lt;b&gt; a word &lt;/b&gt;&#39;;

When I do this in my twig template:

    {{ word }}

I get this:

    &amp;lt;b&amp;gt; a word &amp;lt;b&amp;gt;

I want this instead:

    &lt;b&gt; a word &lt;/b&gt;

Is it possible to get this easily?

I&#39;m using the symfony2 framework and I want to use the PHP&#39;s DateTime class (PHP version is 5.3).

Here the declaration:

    namespace SDCU\GeneralBundle\Entity;

    class Country
    {
	   public function __construct(){
		   $this-&gt;insertedAt = new DateTime();
	   }
    }

But, when executing this constructor, I get an error saying that there&#39;s no &quot;SDCU\GeneralBundle\Entity\DateTime&quot; class. I&#39;ve been searching around for DateTime&#39;s namespace but with no success... any idea?


PHP DateTime class Namespace

Example:

    list($fruit1, $fruit2) = array(&#39;apples&#39;, &#39;oranges&#39;);

code above of course works ok, but code below:

    list($fruit1, $fruit2) = array(&#39;fruit1&#39; =&gt; &#39;apples&#39;, &#39;fruit2&#39; =&gt; &#39;oranges&#39;);

gives: `Notice: Undefined offset: 1 in....`

Is there any way to refer to named keys somehow with list like `list(&#39;fruit1&#39; : $fruit1)`, have you seen anything like this planned for future release?

It seem I have problem with a twig if statement.

    {%if fields | length &gt; 0 || trans_fields | length &gt; 0 -%}

The error is:

    Unexpected token &quot;punctuation&quot; of value &quot;|&quot; (&quot;name&quot; expected) in 

I can&#39;t understand why this doesn&#39;t work, it&#39;s like if twig was lost with all the pipes.

I&#39;ve tried this :

    {% set count1 = fields | length %}
    {% set count2 = trans_fields | length %}
    {%if count1 &gt; 0 || count2 &gt; 0 -%}

but the if also fail.

Then tried this:

    {% set count1 = fields | length &gt; 0 %}
    {% set count2 = trans_fields | length &gt; 0 %}
    {%if count1 || count2 -%}

And it still doesn&#39;t work, same error every time ...


So... that lead me to a really simple question: does Twig support multiple conditions IF ?

twig: IF with multiple conditions

    public List&lt;string&gt; GetpathsById(List&lt;long&gt; id)
    {
        long[] aa = id.ToArray();
            long x;
        List&lt;string&gt; paths = new List&lt;string&gt;();
        for (int i = 0; i &lt; id.Count; i++)
        {
            x = id[i];
            Presentation press = context.Presentations.Where(m =&gt; m.PresId == aa[i]).FirstOrDefault();
            paths.Add(press.FilePath);
        }
        return paths;
    }

This code throws the following exception: `The LINQ expression node type &#39;ArrayIndex&#39; is not supported in LINQ to Entities.` 

However, if I supply `x` instead of `aa[i]` it works.

Why?

I have a NumPy array &#39;boolarr&#39; of boolean type. I want to count the number of elements whose values are `True`. Is there a NumPy or Python routine dedicated for this task? Or, do I need to iterate over the elements in my script?

How can I remove all the duplicate elements from this array while retaining all unique elements without using for-loops and iteration?

I want to parse JSON arrays and using gson. Firstly, I can log JSON output, server is responsing to client clearly. 

Here is my JSON output:

&lt;!-- language: lang-json --&gt;

     [
          {
               id : &#39;1&#39;,
               title: &#39;sample title&#39;,
               ....
          },
          {
               id : &#39;2&#39;,
               title: &#39;sample title&#39;,
               ....
         },
          ...
     ]

I tried this structure for parsing. A class, which depends on single `array` and `ArrayList` for all JSONArray.

&lt;!-- language: lang-java --&gt;

     public class PostEntity {

          private ArrayList&lt;Post&gt; postList = new ArrayList&lt;Post&gt;();

          public List&lt;Post&gt; getPostList() { 
               return postList; 
          }

          public void setPostList(List&lt;Post&gt; postList) { 
               this.postList = (ArrayList&lt;Post&gt;)postList; 
          }	
     }

Post class:

&lt;!-- language: lang-java --&gt;

     public class Post {
     
          private String id;
          private String title;

          /* getters &amp; setters */
     }


When I try to use gson no error, no warning and no log:


&lt;!-- language: lang-java --&gt;

     GsonBuilder gsonb = new GsonBuilder();
     Gson gson = gsonb.create();

     PostEntity postEnt;
     JSONObject jsonObj = new JSONObject(jsonOutput);
     postEnt = gson.fromJson(jsonObj.toString(), PostEntity.class);

     Log.d(&quot;postLog&quot;, postEnt.getPostList().get(0).getId());

What&#39;s wrong, how can I solve?

Pretty self evident question...When using .push() on an array in javascript, is the object pushed into the array a pointer (shallow) or the actual object (deep) *regardless* of type.

Do objects pushed into an array in javascript deep or shallow copy?

Is there a way to push all my local commits to the remote repository *except the most recent one*? I&#39;d like to keep the last one locally just in case I need to do an amend.

git push: Push all commits except the last one

I have made a git commit and subsequent push. I would like to change the commit message. If I understand correctly, this is not advisable because someone might have pulled from the remote repository before I make such changes. What if I know that no one has pulled? 

Is there a way to do this?

I&#39;m looking for alternative ways to push view controllers instantiated on storyboard programmatically.
I&#39;ve actually found two ways, that I use to go to the next view, but also to go back to the previous:

 1. using `pushViewController`:


        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@&quot;MainStoryboard&quot; bundle: nil]; 
        LocationWebView *lvc = [storyboard instantiateViewControllerWithIdentifier:@&quot;LocationWebView&quot;];
        [self.navigationController pushViewController:lvc animated:YES];



 2. performing `Segue` programmatically:

        [self performSegueWithIdentifier: @&quot;SongSegue&quot; sender: self];


Do you have some hints on alternatives and on the best way this operation should be performed? Note that I&#39;m not referring to modal views.
