Navigation Guide written in JavaScript/Ajax/PHP

My order was to develop a navigation guide which should help the visitors to discover the most important content of a website. This “NaviGuide” had to be realized as JavaScript/Ajax/CSS pop up on the fact that much users are using pop up blocker.

This NaviGuide runs since 24.July 2008 at www.stz-baden-baden.de implemented in the well known Content Managment System “Joomla”.

A couple of weeks ago I developed a little “Online Image Uploader” based on my private “JaZzPHP Framework”. The website just consists of a simple upload form as well as rudimentary archive page.

The purpose is to simplify sharing screen shots, images etc..

This is basically a private tool, but if someone needs such a function - fell free to use it.

Hello everybody,

I would like to present you my first little game - called “Starship”.
It is basically a 2D space shooter in a great 80’s look with some funny features.

• S - Start game
• Arrow keys - Steering
• Space - Fire
• ESC - Quit

Please post me some comments and your improvement suggestions!
Have fun with this little pastime game!

Hi guys,

since I’m so often converting strings into MD5 hashs I thought I could quickly set up a little page for doing that. So if you need such a function as well… have a look at the following web address.

I was wondering whether there is a performance difference between count() and sizeof().

<?PHP
 
  // CREATE TEST ARRAY
  $a = array('a','b','c','d','e','f','g','h','i','j');
 
  // START TIMER ONE
  $TimerOne = benchmarkTimerStart();
 
  // CALL COUNT FUNCTION 1000000 TIMES
  for($i=0;$i<1000000;$i++)
  {
    count($a);
  }
 
  // STOP TIMER ONE
  $ResultOne = benchmarkTimerStop($TimerOne);
 
  // START TIMER TWO
  $TimerTwo = benchmarkTimerStart();
 
  // CALL SIZEOF FUNCTION 1000000 TIMES
  for($i=0;$i<1000000;$i++)
  {
    sizeOf($a);
  }
 
  // STOP TIMER TWO
  $ResultTwo = benchmarkTimerStop($TimerTwo);
 
  // PRINT RESULTS
  echo 'Count: '.$ResultOne.' Seconds<br />';
  echo 'SizeOf: '.$ResultTwo.' Seconds';
 
  // TIMER FUNCTIONS
  function benchmarkTimerStart()
  {
    $timeExplode = explode(" ", microtime());
    $time = $timeExplode[1] + $timeExplode[0];
    return $time;
  }
 
  function benchmarkTimerStop($timer=0)
  {
    $timeExplode = explode(" ", microtime());
    $time = $timeExplode[1] + $timeExplode[0];
    $finish = $time - $timer;
    $endTime = sprintf("%4.3f", $finish);
    return $endTime;
  }
?>

My test proved that there is no difference at all! sizeof() is just an alias for count().
So I suggest you to use count() - its the original name of this function.

A couple of days ago i was forced to get in touch with the well known CMS framework “Joomla”. First of all i was a little bit confused about the system mambot/module/component… but it seems to be logical.

First Joomla Mambot

To learn the hole thing I decided to develop a small script witch preloades every picture on a page.

The Mambot

The script itselfe i absolutely simple. I developed a preload function based on PHP5/XHTML/CSS which is very modern and  supported by every browser as well.

This first encounter between Joomla and me is already in use. Feel free to observe the “live demo” on the following web address.

Have a nice day,

Vor ein paar Tagen wurde ich zum wiederholten mal gefragt, wie man einen Counter in PHP entwickelt, welcher die Dauer des Aufenthalt eines Besuchers auf einer Website ermitteln kann.

Der Ansatz

Um einen Online-Zeit Zähler zu programmieren muss man entweder Cookies oder Session Variabeln verwenden. Zudem, da PHP Serverseitig läuft kann man niemals zu 100% genau sagen wie lange sich ein Benutzer auf der Website aufhält. Desweiteren muss man sich auf eine Genauigkeit festlegen (bsp.: 60 Sec).

Der Code

Falls ihr Fragen dazu habt - einfach posten!

Leider gibt es in PHP keine Properties wie in vielen Sprachen.

Um die Vorzüge von Properties doch nutzen zu können, habe ich hier eine möglichkeit um dies zu realisieren.

<?PHP
 
  class TestClass
  {
 
    // INITIALIZE VARIABLES
    private $Variable	= NULL;  	
 
    public function __construct()
    {
      // SET VARIABLE
      $this->Variable = "Example";
    }
 
    public function __destruct() { }
 
    // PROPERTY
    public function prop_Variable($Value=NULL)
    {
      //SET
      if($Value!=NULL) $this->Variable = $Value;
 
      //GET
      else return $this->Variable;
    }
  }
 
  //CreateObject
  $obj_Test = new  TestClass;
 
  // SET VARIABLE
  $obj_Test->prop_Variable('Content');
 
  // GET VARIABLE
  echo $obj_Test->prop_Variable();
 
?>

Ich wünsche viel Spaß damit!

Mit freundlichen Grüßen,
