<?php
// The generic class which can act standalone.
Class OireMail {
// these are required
public $smtp_server="";
public $domain="";
public $from="";
public $login="";
public $pass="";
public function __construct($smtp_server = '', $domain = '', $from =
'', $login = '', $pass = '') {
$this->stmp_server = $smtp_server;
$this->domain = $domain;
$this->from = $from;
$this->login = $login;
$this->pass = $pass;
}
}
// Let's create a generic email class and supply all the params.
$Mail = new OireMail('Server', 'Domain', 'from@domain.com',
'login',
'Passw0rd');
// A more specialised version of the class with all the required params pre set.
Class SpecialisedOireMail extends OireMail {
public function __construct() {
parent::__construct('SpecServer', 'SpecDomain',
'Spec@SpecDomain.com', 'SpecLogin', 'SpecPassw0rd');
}
}
// Let's create a specialised version. Note - no need to supply params
as the sub-class deals with that.
$SpecMail = new SpecialisedOireMail();
var_dump($Mail, $SpecMail);
?>
outputs ...
object(OireMail)#1 (6) {
["smtp_server"]=>
string(0) ""
["domain"]=>
string(6) "Domain"
["from"]=>
string(15) "from@domain.com"
["login"]=>
string(5) "login"
["pass"]=>
string(8) "Passw0rd"
["stmp_server"]=>
string(6) "Server"
}
object(SpecialisedOireMail)#2 (6) {
["smtp_server"]=>
string(0) ""
["domain"]=>
string(10) "SpecDomain"
["from"]=>
string(19) "Spec@SpecDomain.com"
["login"]=>
string(9) "SpecLogin"
["pass"]=>
string(12) "SpecPassw0rd"
["stmp_server"]=>
string(10) "SpecServer"
}
Hope that helps.
