class Foobar {
/**
* @constructor
*/
  function Foobar($params) {
    foreach ($params as $key=>$val) {
      $this->$key= $val;
    }
  }
}

hiermit erzeugt man einfach mal beliebige Klassenvariablen. Man kann das auch gleich noch besonders toll machen und “magische” getter und setter benutzen:

public function __set($var, $val){
  $this->$var = $val;
}

public function __get($var){
  if(isset($this->$var)){
    return $this->$var;
  } else {
    throw new Exception("Property ‘$var’ does not exist");
  }
}

Echt toll. Somit weiß man _nie_ welche Variablen ein Objekt zur Zeit hat. Tolle Sache.

function is_negative($number) {
return substr((string)$number, 0, 1) === '-';
}

Ich lass das einfach mal so stehen …

Ein Quellcodebeispiel gibt es hier: http://blog.maartenballiauw.be/post/2009/04/27/PHPPowerPoint-010-(CTP1)-released!.aspx

Das Zipfile das es zum Download gibt, enthält auch vier Testfälle. In meinem Fall musste ich noch den XMLWriter mit in PHP einkompilieren und danach noch ein paar Dateien und Verzeichnisse umbennen, da Linux bekanntlich sehr auf Groß- und Kleinschreibung achtet (PHPPowerpoint.php != PHPPowerPoint.php). Anyway, hier ein Beispielcode aus dem Zip und danach die generierte Powerpoint-Datei:

Und dieses PDF hab ich aus dem Ergebnis erstellt (dazu brauch man dann wieder Powerpoint 2007, das kann die Klasse glaube ich nicht )

Soweit so gut.

Jetzt hab ich einfach auf dem Server auf dem der Core läuft folgendes PHP-Script hinterlegt:

#!/usr/bin/php -q

Keinerlei Fehlerbehandlung, wenns schiefläuft geht bestimmt irgendwas irreperabel kaputt. Keine Garantie für nichts Ein möglicher Aufruf wäre:

14:34:46 pennywise ~# ./searchQuassel.php -h quassel-storage.sqlite -u pennywise -c quassel.de -s foobar
2008-11-03 11:49:01 (#quassel.de) pennywise    : und da war der Bot jetzt halt drin, weil er irgendwas gesagt hat wie "hallo foobar, wilkkommen in der hölle"
2008-11-06 20:35:57 (#quassel.de) pennywise    : kann ich auch ein temporäres netzwerk haben? sowas wie /join irc.server.com/#foobar?
2008-11-12 11:52:56 (#quassel.de) hanswurst    : im core-log steht nur "foobar benutzer x getrennt"

manpage

-h : Pfad zur SQLite-DB von quasselcore. Liegt meist in ~/.config/quassel-irc.org/
-u : Der Benutzer mit dem man sich in quassel einloggt. Dies hat nichts mit der IRC-Identität zu tun.
-c : Der Channel (bzw. das Query) in dem gesucht werden soll. Ist case insensitive und kann auch nur teilweise übergeben werden (z.B. "quassel" findet "#quassel", "#quassel.de" und "quassel-announce")
-s : OPTIONAL. Der Text nach dem gesucht werden soll. Wenn weggelassen, dann werden alle Nachrichten im übergebenen Channel zurückgegeben

Ich hatte auch noch ne Version mit Prepared Statements, aber die hat beim "$db->prepare($sql)" einfach kein Statement erzeugt. Ohne Fehlermeldung ohne alles. WTF?!

Scienta ZF Debug Bar

Der aufmerksame Leser hat hier ZF entdeckt und, ja tatsächlich, hier ist die Rede vom Zend Framework.

Die Toolbar erlaubt es einem die SQL-Queries, die Page-Render-Zeit, die Version des ZF und den Speicherverbrauch anzuzeigen. Und noch ein paar Gimmicks mehr, dazu verweise ich aber einfach auf den Original-Blogeintrag.

Noob configuration issue

Ohne Witz. Schon jetzt keine Lust auch nur annähernd mich in sein Problem reinzudenken
