Drupal 7 – Almost here

Andreas Glaser — Tue, 04 Jan 2011 12:06:31 +0000

The waiting is almost over – Drupal 7 is finally going to be released tomorrow the 5th of January 2011.
D7 will bring loads of new and improved features, modules from D6 which proved to be useful that made it into the core and much better default administration layouts.

Especially the new layouts will help newbies to get their heads around Drupal in less time to fully enjoy the endless flexibility and efficiency.

Drupal certainly stood the test of time since it’s release in January 2001 and will definitely experience a boost from this major release.

Google Trends Comparison (Drupal vs Joomla vs Typo3 vs Concrete5)

If you haven’t yet worked with Drupal this is definitely the perfect time to get in touch.

Places all your questions will be answered

Personally I’ve been working with Drupal for many years now and developed quite some business websites on it and it gets my recommendation any time. (if you’re not a bloody rookie ;) )

Drupal – Get Vocabulary Name by VID

Andreas Glaser — Wed, 24 Mar 2010 12:26:30 +0000

This function retrieves vocabulary names by their id.

getVocabularyNameByVID($vid)

^?View Code PHP

function getVocabularyNameByVID($vid) {
  /* make sure vid is numeric */
  if(!is_numeric($vid)) return false;
 
  /* fetch name */
  $result = db_query("SELECT name FROM {vocabulary} WHERE vid = %d", $vid);
  $name = db_fetch_object($result)-&gt;name;
 
  /* return name or false if not found */
  return $name ? $name : false;
}

PHP Comments # // or /* /*

Andreas Glaser — Mon, 22 Mar 2010 10:52:15 +0000

PHP as well as most (all?) other programming languages provide different ways to comment source code.
Most common comment indicators are # , // and /* */ .

^?View Code PHP

# this is a comment
echo 'print something';
// another comment
phpinfo();
/* and one more */
var_dump($_ENV);

Which one should I use?

# vs //

I definitely tend to # since it’s only one character instead of two slashes.

# and // vs. /* */

If you plan to pack your code I would highly recommend to always use /* */ due to it’s source code packer compatibility.

/* */ also provides multi line commenting.

/**
* this
* is a
* valid comment
**/

PHP – SRCDS/HTTP Synchronizer (Linux)

Andreas Glaser — Thu, 03 Dec 2009 17:03:04 +0000

I just came across a script I have totally forgotten about, which I wrote quite a while ago.
I haven’t managed to write a real documentation so far… anyway… feel free to try it.

All you need to do, is to install php in case you haven’t done it already!

Release – Imageloader

Andreas Glaser — Tue, 14 Oct 2008 11:34:58 +0000

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.

Screenshot

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.

Have fun with it!

Online MD5 Hash Generator

Andreas Glaser — Thu, 04 Sep 2008 15:47:19 +0000

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.

Have fun with this little tool.

PHP – count() vs. sizeOf()

Andreas Glaser — Tue, 19 Aug 2008 08:51:57 +0000

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

Test code:

^?View Code PHP

&lt;?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&lt;1000000;$i++)
  {
    count($a);
  }
 
  // STOP TIMER ONE
  $ResultOne = benchmarkTimerStop($TimerOne);
 
  // START TIMER TWO
  $TimerTwo = benchmarkTimerStart();
 
  // CALL SIZEOF FUNCTION 1000000 TIMES
  for($i=0;$i&lt;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;
  }
?&gt;

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.

So long,
Andreas Glaser (aka JaZz)
