<?php
class Test {
public $go ;
private $id ;
function show() {
return "id: {$this->id} go: {$this->go}" ;
}
function __construct()
{
echo "in __construct() ". $this->show() ."\n" ;
$this->go = uniqid() ;
}
}
if (! ($res = mysql_query('SELECT * FROM
test', $db))) {
die('Invalid query: ' . mysql_error() . "\n");
}
while($obj = mysql_fetch_object($res, 'Test') ){
echo "outside ________ ". $obj->show() ."\n\n";
}
?>
This code gives the result:
in __construct() id: 1 go: first
outside ________ id: 1 go: 4845bd99ca2e3
in __construct() id: 2 go: second
outside ________ id: 2 go: 4845bd99ca2fd
It means that __construct() is invoked after filling fields with data from database, eg. it can be
used to change strings into integers.
