the easiest way to use and understand multiple constructors:
<?php
class A
{
function __construct()
{
$a = func_get_args();
$i = func_num_args();
if (method_exists($this,$f='__construct'.$i)) {
call_user_func_array(array($this,$f),$a);
}
}
function __construct1($a1)
{
echo('__construct with 1 param called: '.$a1.PHP_EOL);
}
function __construct2($a1,$a2)
{
echo('__construct with 2 params called: '.$a1.','.$a2.PHP_EOL);
}
function __construct3($a1,$a2,$a3)
{
echo('__construct with 3 params called:
'.$a1.','.$a2.','.$a3.PHP_EOL);
}
}
$o = new A('sheep');
$o = new A('sheep','cat');
$o = new A('sheep','cat','dog');
// results:
// __construct with 1 param called: sheep
// __construct with 2 params called: sheep,cat
// __construct with 3 params called: sheep,cat,dog
