Kohana 3 – ErrorException [ Warning ]: htmlspecialchars() expects at most 3 parameters, 4 given

1	ErrorException [ Warning ]: htmlspecialchars() expects at most 3 parameters, 4 given

If Kohana 3 throws this exception, that means that your currently installed PHP version is lower than 5.2.3 .
This can be easily be fixed by updating PHP to the latest stable version (recommended) or by changing one of Kohana (not recommended).

To fix it code wise open following file with your preferred editor

^?View Code CODE

1	/system/classes/kohana/html.php

Search for…

^?View Code PHP

1	return htmlspecialchars((string) $value, ENT_QUOTES, Kohana::$charset, $double_encode);

… and change it into

^?View Code PHP

1	return htmlspecialchars((string) $value, ENT_QUOTES, Kohana::$charset);

Done :)

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”.

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,

PHP Online-Zeit Zähler

Andreas Glaser — Tue, 10 Jun 2008 13:41:41 +0000

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!
