Class Verkettung

class a {

    var $str = 0;

    function b(){

        echo $this->str++ . ' ';    

        return $this;

    }

}

$a = new a();

$a->b()->b()->b()->b()->b()->b()->b()->b()->b()->b()->b()->b()->b();

echo $a->str;

Wichtig ist, dass die Rückgabewert selber eine Klasse ist.

Damit man GEOIP-PECL auf Debian zum laufen bringt:

  1. apt-get install geoip-bin geoip-database libgeoip-dev

     
  2. pecl install geoip

     
  3. Eintrag in php.ini: extension=geoip.so

Danach Apache neu starten oder Konfigurationsdatei neu laden.

<?php

echo geoip_country_code_by_name (  $ip );

// Ausgabe sollte zweistellige Ländercode wie DE oder ähnliches sein.

?>
