Yes ...whatever order you will give to foreach it will iterate in same orders. And in your case `array will be sorted in the output file.`

The relevant reference might not be that of `foreach` or sorting as previously mentionned, but that of array instead.

[Language reference&#160;—&#160;Arrays](http://www.php.net/manual/en/language.types.array.php) says:
&gt; An array in PHP is actually an ordered map.



This is correct, `foreach` will output in same order as the input array .

Yes - the items will be output in the same order they are in within the array.

    import android.app.Activity;
    import android.os.Bundle;
    
    import android.content.ContentResolver;
    import android.content.ContentValues;
    import android.provider.ContactsContract;

        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            try {
    	        ContentResolver cr = this.getContentResolver();
    	        ContentValues cv = new ContentValues();
    	        cv.put(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, &quot;New Name&quot;);
    	        cv.put(ContactsContract.CommonDataKinds.Phone.NUMBER, &quot;1234567890&quot;);
    	        cv.put(ContactsContract.CommonDataKinds.Phone.TYPE, ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE);
    	        cr.insert(ContactsContract.RawContacts.CONTENT_URI, cv);

Hallo,

I&#39;m trying to let a python script run as service (daemon) on (ubuntu) linux.

On the web there exist several solutions like:

http://pypi.python.org/pypi/python-daemon/

&gt; A well-behaved Unix daemon process is tricky to get right, but the required steps are much the same for every daemon program. A DaemonContext instance holds the behaviour and configured process environment for the program; use the instance as a context manager to enter a daemon state.

http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/

However as I want to integrate my python script specifically with ubuntu linux my solution is a combination with an init.d script

    #!/bin/bash

    WORK_DIR=&quot;/var/lib/foo&quot;
    DAEMON=&quot;/usr/bin/python&quot;
    ARGS=&quot;/opt/foo/linux_service.py&quot;
    PIDFILE=&quot;/var/run/foo.pid&quot;
    USER=&quot;foo&quot;

    case &quot;$1&quot; in
      start)
        echo &quot;Starting server&quot;
        mkdir -p &quot;$WORK_DIR&quot;
        /sbin/start-stop-daemon --start --pidfile $PIDFILE \
            --user $USER --group $USER \
            -b --make-pidfile \
            --chuid $USER \
            --exec $DAEMON $ARGS
        ;;
      stop)
        echo &quot;Stopping server&quot;
        /sbin/start-stop-daemon --stop --pidfile $PIDFILE --verbose
        ;;
      *)
        echo &quot;Usage: /etc/init.d/$USER {start|stop}&quot;
        exit 1
        ;;
    esac

    exit 0

and in python:

    import signal
    import time
    import multiprocessing

    stop_event = multiprocessing.Event()

    def stop(signum, frame):
        stop_event.set()

    signal.signal(signal.SIGTERM, stop)

    if __name__ == &#39;__main__&#39;:
        while not stop_event.is_set():
            time.sleep(3)

My question now is if this approach is correct. Do I have to handle any additional signals? Will it be a &quot;well-behaved Unix daemon process&quot;?

When an array is passed to `foreach` is the output order guaranteed to be the same as the input? I know in some languages that the output order is not guaranteed since each element is processed at the same time.

For example, I&#39;m passing a sorted array to `foreach` to write to a file. I want to be sure that the array will be sorted in the output file.

Is foreach guaranteed to iterate in the array order in php?

Last week I learned that classes can be included in your project by writing an `__autoload()` function. Then I learned that using an autoloader isn&#39;t only a technique but also a pattern.

Now I&#39;m using the autoloader in my project and I&#39;ve found it very very useful. I was wondering if it could be possible to do the same thing with functions. It could be very useful to forget about including the right PHP file with functions inside it. 

So, is it possible to create a function autoloader?

Autoloader for functions

When interpolating PHP&#39;s string-indexed array elements (5.3.3, Win32)
the following behavior may be expected or not:

    $ha = array(&#39;key1&#39; =&gt; &#39;Hello to me&#39;);

    print $ha[&#39;key1&#39;];   # correct (usual way)
    print $ha[key1];     # Warning, works (use of undefined constant)

    print &quot;He said {$ha[&#39;key1&#39;]}&quot;; # correct (usual way)
    print &quot;He said {$ha[key1]}&quot;;   # Warning, works (use of undefined constant)

    print &quot;He said $ha[&#39;key1&#39;]&quot;;   # Error, unexpected T_ENCAPSED_AND_WHITESPACE
    print &quot;He said $ha[ key1 ]&quot;;   # Error, unexpected T_ENCAPSED_AND_WHITESPACE
    print &quot;He said $ha[key1]&quot;;     # !! correct (How Comes?)

Inerestingly, **the last line seems to be correct PHP code**. Any explanations?
Can this feature be trusted?



&lt;hr&gt;
Edit: The point of the posting now set in **bold face** in order to reduce misunderstandings.


Interpolation (double quoted string) of Associative Arrays in PHP

Looking through codeigniter&#39;s source code,

in its helper functions I keep seeing code
`$CI =&amp; get_instance();`
can anyone please explain to me how this code works?

I get that it is returning a reference to the $CI super object, but where does `get_instance()` come from?

explain $CI =&amp; get_instance();

This may be really easy but I can&#39;t find a PHP function to do this...

OK so

    $dow_numeric = date(&#39;w&#39;);

gives the numeric day of the week 0-6 for Sunday to Saturday.

And

    $dow_text = date(&#39;D&#39;);

gives the 3 letter abbreviation for the text day of the week (Sun, Mon, etc.)

Is there a function or easy way to use `$dow_numeric` to get `$dow_text`?  If I have &#39;0&#39; as `$dow_numeric`, how can I make `$dow_text = &#39;Sun&#39;`?  Yes a `switch` statement could do the job, but I’m looking for a more elegant solution.

      foreach ($a as &amp;$v) { }
      foreach ($a as $v) { }
    
      print_r($a);
    ?&gt;

I think it&#39;s a normal program but this is the output I am getting:

    )

Can someone please explain this to me?

Strange behavior Of foreach

In C#, Does foreach automatically call Dispose on any object implementing IDisposable?


http://msdn.microsoft.com/en-us/library/aa664754(v=vs.71).aspx seems to indicate that it does:

*Otherwise, the collection expression is of a type that implements System.IEnumerable, and the expansion of the foreach statement is:
Copy

    IEnumerator enumerator = 
            ((System.Collections.IEnumerable)(collection)).GetEnumerator();
    try {
       while (enumerator.MoveNext()) {
          ElementType element = (ElementType)enumerator.Current;
          statement;
       }
    }
    finally {
       IDisposable disposable = enumerator as System.IDisposable;
       if (disposable != null) disposable.Dispose();
    }

Does foreach automatically call Dispose?

I have a question regarding the native `Array.forEach` implementation of JavaScript: Does it behave asynchronously?
For example, if I call:

    [many many elements].forEach(function () {lots of work to do})

Will this be non-blocking?

JavaScript, Node.js: is Array.forEach asynchronous?

I have a foreach loop and I want to see if there is a next element in the loop so I can compare the current element with the next. How can I do this? I&#39;ve read about the current and next functions but I can&#39;t figure out how to use them.

Thanks in advance

there are some informative posts on how to create a counter for loops in an R program.  However, how do you create a similar function when using the parallelized version with &quot;foreach()&quot;?
