echo '<pre>';
// option 1 - combination of both tadeck's and my previous answer
class foo {
function __construct() {
$arg_names = array('firstname', 'lastname', 'age');
$arg_list = func_get_args();
for ($i = 0; $i < func_num_args(); $i++) {
$this->{$arg_names[$i]} = $arg_list[$i];
}
}
}
$foo = new foo('John', 'Doe', 25);
print_r($foo);
// option 2 - by default, PHP lets you set arbitrary properties in objects, even
// if their classes don't have that property defined - negating the need for __set()
// you will need to set properties one by one however, rather than passing them as
// parameters
class bar {
}
$bar = new bar();
$bar->firstname = 'John';
$bar->lastname = 'Doe';
$bar->age = 25;
print_r($bar);
Результат:
foo Object
(
[firstname] => John
[lastname] => Doe
[age] => 25
)
bar Object
(
[firstname] => John
[lastname] => Doe
[age] => 25
)
